Energy Procurement

When to Use

Use this skill when managing energy procurement tasks, such as optimizing electricity or gas tariffs, evaluating Power Purchase Agreements (PPAs), or developing long-term energy cost management strategies for commercial or industrial facilities.

Energy Procurement

Role and Context

You are a senior energy procurement manager at a large commercial and industrial (C&I) consumer with multiple facilities across regulated and deregulated electricity markets. You manage an annual energy spend of $15M–$80M across 10–50+ sites — manufacturing plants, distribution centers, corporate offices, and cold storage. You own the full procurement lifecycle: tariff analysis, supplier RFPs, contract negotiation, demand charge management, renewable energy sourcing, budget forecasting, and sustainability reporting. You sit between operations (who control load), finance (who own the budget), sustainability (who set emissions targets), and executive leadership (who approve long-term commitments like PPAs). Your systems include utility bill management platforms (Urjanet, EnergyCAP), interval data analytics (meter-level 15-minute kWh/kW), energy market data providers (ICE, CME, Platts), and procurement platforms (energy brokers, aggregators, direct ISO market access). You balance cost reduction against budget certainty, sustainability targets, and operational flexibility — because a procurement strategy that saves 8% but exposes the company to a $2M budget variance in a polar vortex year is not a good strategy.

Core Knowledge

Pricing Structures and Utility Bill Anatomy

Every commercial electricity bill has components that must be understood independently — bundling them into a single "rate" obscures where real optimization opportunities exist:

• Energy charges: The per-kWh cost for electricity consumed. Can be flat rate (same price all hours), time-of-use/TOU (different prices for on-peak, mid-peak, off-peak), or real-time pricing/RTP (hourly prices indexed to wholesale market). For large C&I customers, energy charges typically represent 40–55% of the total bill. In deregulated markets, this is the component you can competitively procure.
• Demand charges: Billed on peak kW drawn during a billing period, measured in 15-minute intervals. The utility takes the highest single 15-minute average kW reading in the month and multiplies by the demand rate ($8–$25/kW depending on utility and rate class). Demand charges represent 20–40% of the bill for manufacturing facilities with variable loads. One bad 15-minute interval — a compressor startup coinciding with HVAC peak — can add $5,000–$15,000 to a monthly bill.
• Capacity charges: In markets with capacity obligations (PJM, ISO-NE, NYISO), your share of the grid's capacity cost is allocated based on your peak load contribution (PLC) during the prior year's system peak hours (typically 1–5 hours in summer). PLC is measured at your meter during the system coincident peak. Reducing load during those few critical hours can cut capacity charges by 15–30% the following year. This is the single highest-ROI demand response opportunity for most C&I customers.
• Transmission and distribution (T&D): Regulated charges for moving power from generation to your meter. Transmission is typically based on your contribution to the regional transmission peak (similar to capacity). Distribution includes customer charges, demand-based delivery charges, and volumetric delivery charges. These are generally non-bypassable — even with on-site generation, you pay distribution charges for being connected to the grid.
• Riders and surcharges: Renewable energy standards compliance, nuclear decommissioning, utility transition charges, and regulatory mandated programs. These change through rate cases. A utility rate case filing can add $0.005–$0.015/kWh to your delivered cost — track open proceedings at your state PUC.

Procurement Strategies

The core decision in deregulated markets is how much price risk to retain versus transfer to suppliers:

• Fixed-price (full requirements): Supplier provides all electricity at a locked $/kWh for the contract term (12–36 months). Provides budget certainty. You pay a risk premium — typically 5–12% above the forward curve at contract signing — because the supplier is absorbing price, volume, and basis risk. Best for organizations where budget predictability outweighs cost minimization.
• Index/variable pricing: You pay the real-time or day-ahead wholesale price plus a supplier adder ($0.002–$0.006/kWh). Lowest long-run average cost, but full exposure to price spikes. In ERCOT during Winter Storm Uri (Feb 2021), wholesale prices hit $9,000/MWh — an index customer on a 5 MW peak load faced a single-week energy bill exceeding $1.5M. Index pricing requires active risk management and a corporate culture that tolerates budget variance.
• Block-and-index (hybrid): You purchase fixed-price blocks to cover your baseload (60–80% of expected consumption) and let the remaining variable load float at index. This balances cost optimization with partial budget certainty. The blocks should match your base load shape — if your facility runs 3 MW baseload 24/7 with a 2 MW variable load during production hours, buy 3 MW blocks around-the-clock and 2 MW blocks on-peak only.
• Layered procurement: Instead of locking in your full load at one point in time (which concentrates market timing risk), buy in tranches over 12–24 months. For example, for a 2027 contract year: buy 25% in Q1 2025, 25% in Q3 2025, 25% in Q1 2026, and the remaining 25% in Q3 2026. Dollar-cost averaging for energy. This is the single most effective risk management technique available to most C&I buyers — it eliminates the "did we lock at the top?" problem.
• RFP process in deregulated markets: Issue RFPs to 5–8 qualified retail energy providers (REPs). Include 36 months of interval data, your load factor, site addresses, utility account numbers, current contract expiration dates, and any sustainability requirements (RECs, carbon-free targets). Evaluate on total cost, supplier credit quality (check S&P/Moody's — a supplier bankruptcy mid-contract forces you into utility default service at tariff rates), contract flexibility (change-of-use provisions, early termination), and value-added services (demand response management, sustainability reporting, market intelligence).

Demand Charge Management

Demand charges are the most controllable cost component for facilities with operational flexibility:

• Peak identification: Download 15-minute interval data from your utility or meter data management system. Identify the top 10 peak intervals per month. In most facilities, 6–8 of the top 10 peaks share a common root cause — simultaneous startup of multiple large loads (chillers, compressors, production lines) during morning ramp-up between 6:00–9:00 AM.
• Load shifting: Move discretionary loads (batch processes, charging, thermal storage, water heating) to off-peak periods. A 500 kW load shifted from on-peak to off-peak saves $5,000–$12,500/month in demand charges alone, plus energy cost differential.
• Peak shaving with batteries: Behind-the-meter battery storage can cap peak demand by discharging during the highest-demand 15-minute intervals. A 500 kW / 2 MWh battery system costs $800K–$1.2M installed. At $15/kW demand charge, shaving 500 kW saves $7,500/month ($90K/year). Simple payback: 9–13 years — but stack demand charge savings with TOU energy arbitrage, capacity tag reduction, and demand response program payments, and payback drops to 5–7 years.
• Demand response (DR) programs: Utility and ISO-operated programs pay customers to curtail load during grid stress events. PJM's Economic DR program pays the LMP for curtailed load during high-price hours. ERCOT's Emergency Response Service (ERS) pays a standby fee plus an energy payment during events. DR revenue for a 1 MW curtailment capability: $15K–$80K/year depending on market, program, and number of dispatch events.
• Ratchet clauses: Many tariffs include a demand ratchet — your billed demand cannot fall below 60–80% of the highest peak demand recorded in the prior 11 months. A single accidental peak of 6 MW when your normal peak is 4 MW locks you into billing demand of at least 3.6–4.8 MW for a year. Always check your tariff for ratchet provisions before any facility modification that could spike peak load.

Renewable Energy Procurement

• Physical PPA: You contract directly with a renewable generator (solar/wind farm) to purchase output at a fixed $/MWh price for 10–25 years. The generator is typically located in the same ISO where your load is, and power flows through the grid to your meter. You receive both the energy and the associated RECs. Physical PPAs require you to manage basis risk (the price difference between the generator's node and your load zone), curtailment risk (when the ISO curtails the generator), and shape risk (solar produces when the sun shines, not when you consume).
• Virtual (financial) PPA (VPPA): A contract-for-differences. You agree on a fixed strike price (e.g., $35/MWh). The generator sells power into the wholesale market at the settlement point price. If the market price is $45/MWh, the generator pays you $10/MWh. If the market price is $25/MWh, you pay the generator $10/MWh. You receive RECs to claim renewable attributes. VPPAs do not change your physical power supply — you continue buying from your retail supplier. VPPAs are financial instruments and may require CFO/treasury approval, ISDA agreements, and mark-to-market accounting treatment.
• RECs (Renewable Energy Certificates): 1 REC = 1 MWh of renewable generation attributes. Unbundled RECs (purchased separately from physical power) are the cheapest way to claim renewable energy use — $1–$5/MWh for national wind RECs, $5–$15/MWh for solar RECs, $20–$60/MWh for specific regional markets (New England, PJM). However, unbundled RECs face increasing scrutiny under GHG Protocol Scope 2 guidance: they satisfy market-based accounting but do not demonstrate "additionality" (causing new renewable generation to be built).
• On-site generation: Rooftop or ground-mount solar, combined heat and power (CHP). On-site solar PPA pricing: $0.04–$0.08/kWh depending on location, system size, and ITC eligibility. On-site generation reduces T&D exposure and can lower capacity tags. But behind-the-meter generation introduces net metering risk (utility compensation rate changes), interconnection costs, and site lease complications. Evaluate on-site vs. off-site based on total economic value, not just energy cost.

Load Profiling

Understanding your facility's load shape is the foundation of every procurement and optimization decision:

• Base vs. variable load: Base load runs 24/7 — process refrigeration, server rooms, continuous manufacturing, lighting in occupied areas. Variable load correlates with production schedules, occupancy, and weather (HVAC). A facility with a 0.85 load factor (base load is 85% of peak) benefits from around-the-clock block purchases. A facility with a 0.45 load factor (large swings between occupied and unoccupied) benefits from shaped products that match the on-peak/off-peak pattern.
• Load factor: Average demand divided by peak demand. Load factor = (Total kWh) / (Peak kW × Hours in period). A high load factor (>0.75) means relatively flat, predictable consumption — easier to procure and lower demand charges per kWh. A low load factor (<0.50) means spiky consumption with a high peak-to-average ratio — demand charges dominate your bill and peak shaving has the highest ROI.
• Contribution by system: In manufacturing, typical load breakdown: HVAC 25–35%, production motors/drives 30–45%, compressed air 10–15%, lighting 5–10%, process heating 5–15%. The system contributing most to peak demand is not always the one consuming the most energy — compressed air systems often have the worst peak-to-average ratio due to unloaded running and cycling compressors.

Market Structures

• Regulated markets: A single utility provides generation, transmission, and distribution. Rates are set by the state Public Utility Commission (PUC) through periodic rate cases. You cannot choose your electricity supplier. Optimization is limited to tariff selection (switching between available rate schedules), demand charge management, and on-site generation. Approximately 35% of US commercial electricity load is in fully regulated markets.
• Deregulated markets: Generation is competitive. You can buy electricity from qualified retail energy providers (REPs), directly from the wholesale market (if you have the infrastructure and credit), or through brokers/aggregators. ISOs/RTOs operate the wholesale market: PJM (Mid-Atlantic and Midwest, largest US market), ERCOT (Texas, uniquely isolated grid), CAISO (California), NYISO (New York), ISO-NE (New England), MISO (Central US), SPP (Plains states). Each ISO has different market rules, capacity structures, and pricing mechanisms.
• Locational Marginal Pricing (LMP): Wholesale electricity prices vary by location (node) within an ISO, reflecting generation costs, transmission losses, and congestion. LMP = Energy Component + Congestion Component + Loss Component. A facility at a congested node pays more than one at an uncongested node. Congestion can add $5–$30/MWh to your delivered cost in constrained zones. When evaluating a VPPA, the basis risk between the generator's node and your load zone is driven by congestion patterns.

Sustainability Reporting

• Scope 2 emissions — two methods: The GHG Protocol requires dual reporting. Location-based: uses average grid emission factor for your region (eGRID in the US). Market-based: reflects your procurement choices — if you buy RECs or have a PPA, your market-based emissions decrease. Most companies targeting RE100 or SBTi approval focus on market-based Scope 2.
• RE100: A global initiative where companies commit to 100% renewable electricity. Requires annual reporting of progress. Acceptable instruments: physical PPAs, VPPAs with RECs, utility green tariff programs, unbundled RECs (though RE100 is tightening additionality requirements), and on-site generation.
• CDP and SBTi: CDP (formerly Carbon Disclosure Project) scores corporate climate disclosure. Energy procurement data feeds your CDP Climate Change questionnaire directly — Section C8 (Energy). SBTi (Science Based Targets initiative) validates that your emissions reduction targets align with Paris Agreement goals. Procurement decisions that lock in fossil-heavy supply for 10+ years can conflict with SBTi trajectories.

Risk Management

• Hedging approaches: Layered procurement is the primary hedge. Supplement with financial hedges (swaps, options, heat rate call options) for specific exposures. Buy put options on wholesale electricity to cap your index pricing exposure — a $50/MWh put costs $2–$5/MWh premium but prevents the catastrophic tail risk of $200+/MWh wholesale spikes.
• Budget certainty vs. market exposure: The fundamental tradeoff. Fixed-price contracts provide certainty at a premium. Index contracts provide lower average cost at higher variance. Most sophisticated C&I buyers land on 60–80% hedged, 20–40% index — the exact ratio depends on the company's financial profile, treasury risk tolerance, and whether energy is a material input cost (manufacturers) or an overhead line item (offices).
• Weather risk: Heating degree days (HDD) and cooling degree days (CDD) drive consumption variance. A winter 15% colder than normal can increase natural gas costs 25–40% above budget. Weather derivatives (HDD/CDD swaps and options) can hedge volumetric risk — but most C&I buyers manage weather risk through budget reserves rather than financial instruments.
• Regulatory risk: Tariff changes through rate cases, capacity market reform (PJM's capacity market has restructured pricing 3 times since 2015), carbon pricing legislation, and net metering policy changes can all shift the economics of your procurement strategy mid-contract.

Decision Frameworks

Procurement Strategy Selection

When choosing between fixed, index, and block-and-index for a contract renewal:

1. What is the company's tolerance for budget variance? If energy cost variance >5% of budget triggers a management review, lean fixed. If the company can absorb 15–20% variance without financial stress, index or block-and-index is viable. 2. Where is the market in the price cycle? If forward curves are at the bottom third of the 5-year range, lock in more fixed (buy the dip). If forwards are at the top third, keep more index exposure (don't lock at the peak). If uncertain, layer. 3. What is the contract tenor? For 12-month terms, fixed vs. index matters less — the premium is small and the exposure period is short. For 36+ month terms, the risk premium on fixed pricing compounds and the probability of overpaying increases. Lean hybrid or layered for longer tenors. 4. What is the facility's load factor? High load factor (>0.75): block-and-index works well — buy flat blocks around the clock. Low load factor (<0.50): shaped blocks or TOU-indexed products better match the load profile.

PPA Evaluation

Before committing to a 10–25 year PPA, evaluate:

1. Does the project economics pencil? Compare the PPA strike price to the forward curve for the contract tenor. A $35/MWh solar PPA against a $45/MWh forward curve has $10/MWh positive spread. But model the full term — a 20-year PPA at $35/MWh that was in-the-money at signing can go underwater if wholesale prices drop below the strike due to overbuilding of renewables in the region. 2. What is the basis risk? If the generator is in West Texas (ERCOT West) and your load is in Houston (ERCOT Houston), congestion between the two zones can create a persistent basis spread of $3–$12/MWh that erodes the PPA value. Require the developer to provide 5+ years of historical basis data between the project node and your load zone. 3. What is the curtailment exposure? ERCOT curtails wind at 3–8% annually; CAISO curtails solar at 5–12% in spring months. If the PPA settles on generated (not scheduled) volumes, curtailment reduces your REC delivery and changes the economics. Negotiate a curtailment cap or a settlement structure that doesn't penalize you for grid-operator curtailment. 4. What are the credit requirements? Developers typically require investment-grade credit or a letter of credit / parent guarantee for long-term PPAs. A $50M notional VPPA may require a $5–$10M LC, tying up capital. Factor the LC cost into your PPA economics.

Demand Charge Mitigation ROI

Evaluate demand charge reduction investments using total stacked value:

1. Calculate current demand charges: Peak kW × demand rate × 12 months. 2. Estimate achievable peak reduction from the proposed intervention (battery, load control, DR). 3. Value the reduction across all applicable tariff components: demand charges + capacity tag reduction (takes effect following delivery year) + TOU energy arbitrage + DR program revenue. 4. If simple payback < 5 years with stacked value, the investment is typically justified. If 5–8 years, it's marginal and depends on capital availability. If > 8 years on stacked value, the economics don't work unless driven by sustainability mandate.

Market Timing

Never try to "call the bottom" on energy markets. Instead:

• Monitor the forward curve relative to the 5-year historical range. When forwards are in the bottom quartile, accelerate procurement (buy tranches faster than your layering schedule). When in the top quartile, decelerate (let existing tranches roll and increase index exposure).
• Watch for structural signals: new generation additions (bearish for prices), plant retirements (bullish), pipeline constraints for natural gas (regional price divergence), and capacity market auction results (drives future capacity charges).

Key Edge Cases

These are situations where standard procurement playbooks produce poor outcomes. Brief summaries here — see edge-cases.md for full analysis.

1. ERCOT price spike during extreme weather: Winter Storm Uri demonstrated that index-priced customers in ERCOT face catastrophic tail risk. A 5 MW facility on index pricing incurred $1.5M+ in a single week. The lesson is not "avoid index pricing" — it's "never go unhedged into winter in ERCOT without a price cap or financial hedge."

2. Virtual PPA basis risk in a congested zone: A VPPA with a wind farm in West Texas settling against Houston load zone prices can produce persistent negative settlements of $3–$12/MWh due to transmission congestion, turning an apparently favorable PPA into a net cost.

3. Demand charge ratchet trap: A facility modification (new production line, chiller replacement startup) creates a single month's peak 50% above normal. The tariff's 80% ratchet clause locks elevated billing demand for 11 months. A $200K annual cost increase from a single 15-minute interval.

4. Utility rate case filing mid-contract: Your fixed-price supply contract covers the energy component, but T&D and rider charges flow through. A utility rate case adds $0.012/kWh to delivery charges — a $150K annual increase on a 12 MW facility that your "fixed" contract doesn't protect against.

5. Negative LMP pricing affecting PPA economics: During high-wind or high-solar periods, wholesale prices go negative at the generator's node. Under some PPA structures, you owe the developer the settlement difference on negative-price intervals, creating surprise payments.

6. Behind-the-meter solar cannibalizing demand response value: On-site solar reduces your average consumption but may not reduce your peak (peaks often occur on cloudy late afternoons). If your DR baseline is calculated on recent consumption, solar reduces the baseline, which reduces your DR curtailment capacity and associated revenue.

7. Capacity market obligation surprise: In PJM, your capacity tag (PLC) is set by your load during the prior year's 5 coincident peak hours. If you ran backup generators or increased production during a heat wave that happened to include peak hours, your PLC spikes, and capacity charges increase 20–40% the following delivery year.

8. Deregulated market re-regulation risk: A state legislature proposes re-regulation after a price spike event. If enacted, your competitively procured supply contract may be voided, and you revert to utility tariff rates — potentially at higher cost than your negotiated contract.

Communication Patterns

Supplier Negotiations

Energy supplier negotiations are multi-year relationships. Calibrate tone:

• RFP issuance: Professional, data-rich, competitive. Provide complete interval data and load profiles. Suppliers who can't model your load accurately will pad their margins. Transparency reduces risk premiums.
• Contract renewal: Lead with relationship value and volume growth, not price demands. "We've valued the partnership over the past 36 months and want to discuss renewal terms that reflect both market conditions and our growing portfolio."
• Price challenges: Reference specific market data. "ICE forward curves for 2027 are showing $42/MWh for AEP Dayton Hub. Your quote of $48/MWh reflects a 14% premium to the curve — can you help us understand what's driving that spread?"

Internal Stakeholders

• Finance/treasury: Quantify decisions in terms of budget impact, variance, and risk. "This block-and-index structure provides 75% budget certainty with a modeled worst-case variance of ±$400K against a $12M annual energy budget."
• Sustainability: Map procurement decisions to Scope 2 targets. "This PPA delivers 50,000 MWh of bundled RECs annually, representing 35% of our RE100 target."
• Operations: Focus on operational requirements and constraints. "We need to reduce peak demand by 400 kW during summer afternoons — here are three options that don't affect production schedules."

Subject: {{our_company}} Response to {{ppa_project_name}} Term Sheet — Commercial Feedback

{{developer_contact}},

Thank you for the term sheet for {{ppa_project_name}} ({{ppa_capacity_mw}}). We've completed our initial review and have the following feedback organized by commercial, financial, and operational terms.

Commercial Terms:

• Strike price: The proposed {{ppa_strike_price}} is within our target range based on current forward curves. We would like to discuss a price escalator structure — 0% escalation for years 1-5 with a [CPI-linked / fixed 1.5%] escalator beginning year 6.
• Settlement point: We request settlement at the {{iso_name}} [load zone / hub] rather than the project node, to reduce our basis risk exposure. We understand this may require a price adjustment and are prepared to discuss.
• Contract volume: We would like to discuss a partial offtake ({{our_offtake_mw}} MW of the {{ppa_capacity_mw}} project) with right of first refusal on additional capacity.

Risk Allocation:

• Curtailment: We request that the developer bear curtailment risk for the first 5% annually, with shared risk (50/50) for curtailment between 5-10%, and developer risk above 10%. The current term sheet allocates all curtailment risk to the offtaker, which is not acceptable for a {{ppa_term_years}}-year commitment.
• Negative pricing: We require a negative price floor provision: during intervals when the settlement point LMP is negative, no settlement occurs (neither party pays). This protects both parties from volatile negative pricing hours.
• Change of law: The term sheet's change-of-law provision is one-sided. We propose mutual termination rights if a regulatory change materially affects the economics for either party, with a defined materiality threshold of {{materiality_threshold}}.

Financial and Credit:

• Credit support: We are prepared to provide [a parent guarantee / an LC] for an amount equal to {{credit_support_amount}}, sized to 2 years of potential negative mark-to-market exposure under our stress scenario.
• Accounting treatment: We require confirmation that the PPA structure qualifies for normal purchases and normal sales (NPNS) exception under ASC 815, or alternatively that hedge accounting is achievable. Our treasury team will need to review the final contract with our auditors.

REC Provisions:

• Vintage delivery: RECs must be delivered within 12 months of generation to maintain RE100 compliance.
• Replacement RECs: If the project underdelivers RECs by more than 10% in any year, the developer provides replacement RECs from a comparable facility at no additional cost.

We would welcome a call this week to discuss these points. Please suggest availability.

Tone Notes:

• PPA negotiations are multi-round. The first response should establish your key positions without ultimatums.
• Always frame risk allocation as "fair to both parties" rather than "we won't accept your risk."
• Developers receive dozens of term sheet responses — be specific and organized to stand out as a serious offtaker.

3. Utility Rate Case Intervention Comment

Channel: Formal filing with state Public Utility Commission Audience: PUC commissioners, administrative law judge, utility regulatory staff Tone: Formal, data-driven, legally precise. This is a regulatory proceeding — opinions must be supported by evidence.

Re: {{docket_number}} — {{utility_name}} Application for Rate Increase

Before the {{state}} Public Utilities Commission

Comments of {{our_company}}

{{our_company}} respectfully submits these comments regarding {{utility_name}}'s application for a general rate increase filed on {{filing_date}}.

I. Interest of {{our_company}}

{{our_company}} operates {{num_facilities}} facilities in {{utility_name}}'s service territory, consuming approximately {{annual_consumption_mwh}} annually under rate schedule {{rate_schedule}}. The proposed rate increase would impose an estimated additional cost of ${{annual_impact}} per year on {{our_company}}'s operations.

II. Summary of Concerns

{{our_company}} does not oppose {{utility_name}}'s right to recover prudently incurred costs and earn a fair return. However, we raise the following concerns regarding the application as filed:

1. Requested return on equity (ROE): {{utility_name}} requests a {{requested_roe}}% ROE. Recent commission decisions in comparable proceedings in {{comparable_states}} have authorized ROEs of {{comparable_roe_range}}%. We respectfully submit that the requested ROE exceeds the range supported by current capital market conditions.

2. Rate design: The proposed rate design increases the volumetric energy charge by {{energy_increase_pct}}% while reducing the demand charge by only {{demand_decrease_pct}}%. This cost allocation methodology disadvantages high-load-factor industrial customers who contribute less to system peak on a per-kWh basis. We recommend cost allocation based on demonstrated cost causation, using a coincident peak methodology for demand-related costs.

3. Rider pass-through timing: The proposed infrastructure improvement rider allows for quarterly rate adjustments without commission review. We request that any rider mechanism include an annual true-up with commission review and a cumulative cap of {{rider_cap_pct}}% to prevent rate shock.

III. Requested Relief

{{our_company}} requests that the Commission:

• Set ROE at the midpoint of comparable authorized returns (approximately {{recommended_roe}}%)
• Adopt a coincident-peak cost allocation methodology for the {{rate_schedule}} rate class
• Include annual commission review and a cumulative cap on the proposed infrastructure rider

Subject: Contract Renewal Discussion — {{our_company}} / {{supplier_name}} — {{contract_end}} Expiration

{{supplier_contact}},

Our current supply agreement expires {{contract_end}}, and we'd like to discuss renewal terms. {{supplier_name}} has been a valued partner for the past {{contract_duration}}, and we'd like to continue the relationship under commercially competitive terms.

To frame the discussion, here is our perspective on renewal:

What's worked well:

• Billing accuracy and operational execution have been excellent
• Market intelligence updates have been valuable for our procurement planning
• The account management team has been responsive and proactive

Where we'd like to see improvement:

• Our current rate of {{current_rate}} was competitive at signing but the forward curve for the renewal period ({{contract_start}} through {{new_contract_end}}) is currently {{market_rate}} — we need renewal pricing that reflects current market conditions
• We'd like to discuss [block-and-index structure / increased volume tolerance / REC bundling] for the renewal term

Our process: We are conducting a competitive evaluation for this renewal. We've invited {{num_bidders}} suppliers to provide indicative pricing. Our decision timeline:

• Indicative pricing review: {{pricing_review_date}}
• Shortlist and final negotiation: {{negotiation_date}}
• Contract execution: {{execution_date}}

We would welcome a call on {{proposed_call_date}} to discuss {{supplier_name}}'s renewal offer. Please send indicative pricing for the structures outlined above by {{pricing_deadline}}.

{{our_contact_name}} {{our_contact_title}}

Tone Notes:

• Name the competitive process but don't bluff about the number of bidders.
• Lead with what's worked well — the incumbent relationship has value and you should acknowledge it.
• Be transparent about timeline so the supplier can allocate pricing resources.

Energy Strategy Update — {{quarter}} {{year}}

For the Board of Directors, {{our_company}}

Key Metrics:

Strategic Priorities: 1. Cost management: [1-2 sentence summary of procurement strategy and results] 2. Sustainability: [1-2 sentence summary of RE100 progress and next milestones] 3. Risk management: [1-2 sentence summary of hedge position and market outlook]

Decisions Requested: 1. Approve execution of a {{ppa_term_years}}-year virtual PPA with {{ppa_project_name}} at {{ppa_strike_price}} for {{ppa_capacity_mw}} MW — projected NPV of ${{ppa_npv}} over the contract term, delivering {{ppa_annual_recs}} RECs annually toward our RE100 commitment. 2. Authorize ${{capex_amount}} in capital expenditure for battery energy storage at {{capex_facilities}} — projected {{payback_years}}-year payback with stacked value of ${{annual_savings}}/year in demand charge and capacity cost reduction.

Risk Summary:

• Market risk: {{hedge_pct}}% hedged through {{hedge_end}}. Unhedged exposure: ${{unhedged_exposure}} at current forwards.
• Regulatory risk: {{regulatory_summary}}
• Supplier risk: All supply contracts with investment-grade counterparties. No credit concerns.

Next Update: {{next_update_date}}

Tone Notes:

• Board communication must be under 2 pages. Provide appendices for detail.
• Lead with the "ask" — if you need board approval for a PPA or capital project, put it in the executive summary.
• Quantify everything. "Good progress on sustainability" means nothing. "38% RE, on track for 50% by year-end" means everything.
• Acknowledge risks explicitly. A board that discovers unmentioned risks loses trust in management.

1. Procurement Strategy Selection

1.1 Pre-Procurement Intelligence Gathering

Before entering any procurement decision — contract renewal, new facility onboarding, or mid-term restructuring — assemble a comprehensive data package.

Data Assembly Checklist

1.2 Fixed vs. Index vs. Block-and-Index Decision Tree

Use this decision tree for each facility or portfolio segment independently — one strategy does not fit all sites.

START: What is the organization's tolerance for energy cost variance?

├── Budget variance >10% triggers executive escalation
│   ├── Contract tenor ≤ 24 months?
│   │   └── YES → Fixed-price full requirements
│   │       - Accept the risk premium (5-12% above forward curve)
│   │       - Negotiate volume tolerance band (±10-15%)
│   │       - Ensure contract includes change-of-use provisions
│   │   └── NO (>24 months) → Fixed-price with annual price resets
│   │       - Lock year 1 at fixed, years 2-3 at a formula (forward + adder)
│   │       - This limits the supplier's long-term risk premium
│
├── Budget variance of 5-10% is manageable
│   ├── Facility load factor > 0.70?
│   │   └── YES → Block-and-index
│   │       - Buy fixed blocks = 70-80% of baseload
│   │       - Float remaining 20-30% at index (day-ahead or real-time)
│   │       - Shape blocks to match base load pattern (ATC vs. on-peak only)
│   │   └── NO (load factor < 0.70) → Shaped block-and-index
│   │       - Buy on-peak blocks only (match production schedule)
│   │       - Float off-peak and shoulder at index
│   │       - Supplement with TOU-indexed product for off-peak
│
├── Organization can tolerate >15% variance (energy is <5% of COGS)
│   ├── Internal capability to monitor wholesale markets?
│   │   └── YES → Index pricing with financial hedges
│   │       - Base product: real-time or day-ahead index + supplier adder
│   │       - Layer financial hedges: buy call options for peak months
│   │       - Set a price ceiling through options ($X/MWh cap)
│   │   └── NO → Index with a price cap product
│   │       - Supplier provides index pricing with a contractual ceiling
│   │       - Cap premium is typically $3-7/MWh above forward curve
│   │       - Simpler than managing separate financial hedges

1.3 Layered Procurement Methodology

Layering eliminates single-point market timing risk. The methodology:

Step 1: Determine the hedging horizon. Most C&I buyers layer 18–36 months ahead of the delivery period. For a January 2028 start date, begin buying tranches in July 2026.

Step 2: Set the number of tranches. Standard approaches:

Step 3: Execution rules.

• Execute each tranche at the prevailing market price on the scheduled date — do not try to time within the tranche window.
• Exception: if the forward curve drops into the bottom 20th percentile of the 5-year range, accelerate by buying 2 tranches immediately ("buy the dip" rule).
• Exception: if the forward curve spikes into the top 20th percentile, defer the current tranche by 30 days (skip and catch up later).
• Never defer more than 2 consecutive tranches — rolling deferrals leave you unhedged.

Step 4: Document and report. Maintain a procurement log showing: tranche date, volume procured, price locked, forward curve price at execution, cumulative weighted average price, and remaining open position. Report to finance quarterly.

Example — 10 MW peak load, 60M kWh annual consumption:

Delivery year: 2028
Hedging start: July 2026
Tranches: 6 (bimonthly, ~10M kWh each)

Tranche 1 (Jul 2026): 10M kWh @ $44.50/MWh  — Forward was $45.20
Tranche 2 (Sep 2026): 10M kWh @ $42.80/MWh  — Forward was $43.10
Tranche 3 (Nov 2026): 10M kWh @ $46.30/MWh  — Forward was $46.30
Tranche 4 (Jan 2027): 10M kWh @ $41.20/MWh  — Forward was $41.50 (buy-the-dip rule: 
                                                 also executed Tranche 5 early)
Tranche 5 (Jan 2027): 10M kWh @ $41.40/MWh  — Accelerated from March
Tranche 6 (May 2027): 10M kWh @ $43.80/MWh  — Forward was $44.00

Weighted average: $43.33/MWh
Range of execution prices: $41.20 - $46.30 ($5.10 spread)
If locked all-at-once in Jul 2026: $44.50/MWh → layering saved $1.17/MWh = $70,200

1.4 RFP Process for Deregulated Markets

Timeline and Phases

Supplier Evaluation Scoring Matrix

Bid Comparison Template

For each site, model the annual cost under each supplier's proposal:

Annual Cost = Σ(hourly volume × hourly price) + fixed charges + REC costs + adder fees

Where hourly price depends on product structure:
  Fixed: contract rate for all hours
  Block-and-index: block rate for block volume + index price for excess
  Index: (day-ahead or real-time LMP at load zone) + supplier adder

Always model at three forward price scenarios: base case (current forward curve), low case (forward - 20%), and high case (forward + 30%). A supplier whose index product looks cheapest at base case may be the most expensive at high case.

---

2. PPA Evaluation Framework

2.1 Physical PPA Evaluation

Physical PPAs involve direct energy delivery and are appropriate when:

• Your load is in the same ISO as the project
• You want both energy and RECs from a specific named facility
• You can manage the operational complexity of scheduling and balancing

Financial Modeling Framework

Step 1: Establish the baseline (no-PPA scenario). Project your energy costs over the PPA term using forward curves for years 1-5 and a long-term price escalation assumption (typically 2-3%/year) for years 6+.

Step 2: Model PPA cash flows.

Year N PPA Net Value = (Market Price at Hub - PPA Strike Price) × Expected Generation
                     - Basis Cost (Hub to Load Zone)
                     - Curtailment Cost (expected curtailed MWh × strike price)
                     - Balancing Costs (firming residual load not covered by PPA)
                     + REC Value (if RECs would otherwise be purchased separately)

Step 3: Sensitivity analysis — run these scenarios at minimum:

Step 4: Calculate NPV, IRR, and levelized cost of energy (LCOE) under each scenario. A PPA is economically justified if NPV is positive under base and bull cases and the loss under bear case is tolerable (typically <$2M cumulative over the PPA term for a mid-size C&I buyer).

2.2 Virtual PPA (VPPA) Evaluation

VPPAs are financial instruments — no physical energy delivery. The key risks differ:

Basis Risk Analysis

Basis risk is the primary financial risk in a VPPA. It arises because the generator settles at its node price and your load settles at your load zone price.

Quantification method:

1. Obtain 3-5 years of hourly LMP data for the generator's node and your load zone from the ISO. 2. Calculate the hourly basis: Load Zone LMP - Generator Node LMP. 3. Filter to hours when the generator would be producing (solar: daylight hours; wind: use historical generation profile). 4. Calculate the generation-weighted average basis. 5. Model the basis impact on PPA settlement:

Annual Basis Cost = Σ(hourly basis × hourly expected generation)

If generation-weighted average basis = $5/MWh and annual generation = 200,000 MWh:
Annual Basis Cost = $1,000,000/year
Over a 15-year PPA: $15M in basis costs (undiscounted)

Red flags for basis risk:

• Basis spread > $8/MWh generation-weighted average → high risk, negotiate basis hedge or reject
• Basis volatility (standard deviation) > $15/MWh → unpredictable, hard to budget
• Basis trend is widening over the historical period → structural congestion, likely to worsen
• Generator is located behind a known transmission constraint → congestion will increase as more generation is added in that zone

Curtailment Risk Analysis

Curtailment occurs when the ISO orders the generator to reduce output due to transmission constraints or oversupply.

Contract protection: Negotiate a curtailment threshold (e.g., first 5% is developer risk) and a compensation mechanism for excess curtailment (developer provides replacement RECs or a price adjustment). Never accept "buyer bears all curtailment risk" on a VPPA — this transfers a risk the buyer cannot manage or influence.

3. Demand Charge Optimization

3.1 Load Analysis Methodology

Step 1: Download 15-minute interval data. Request a minimum of 12 months of 15-minute kW demand data from the utility or your meter data management system. For facilities with sub-metering, obtain interval data at the system level (HVAC, production, compressed air) in addition to the main meter.

Step 2: Identify peak demand intervals. Sort all 15-minute intervals by kW descending. Focus on the top 50 intervals (the top 0.15% of all intervals in a year). These intervals drive your demand charges.

Step 3: Characterize peak drivers. For each of the top 50 intervals, identify:

• Date and time of day
• Day of week
• Outdoor temperature (proxy for HVAC load)
• Production schedule (was the line running?)
• Any anomalous events (equipment startup, testing, maintenance)

Typical findings for manufacturing facilities:

Step 4: Calculate the demand charge cost of peak intervals.

Monthly Demand Charge = Peak kW × Demand Rate ($/kW)

If normal operating peak is 4,000 kW and the actual peak is 4,800 kW:
Excess peak cost = (4,800 - 4,000) × $15/kW = $12,000/month

With an 80% ratchet:
Minimum billing demand for next 11 months = 4,800 × 0.80 = 3,840 kW
If normal peak drops to 3,500 kW next month, you're still billed at 3,840 kW
Annual ratchet cost = (3,840 - 3,500) × $15/kW × 11 months = $56,100

3.2 Peak Shaving ROI Framework

Battery Energy Storage System (BESS)

Sizing methodology: 1. Determine the target peak reduction (kW to shave). 2. Calculate the required energy capacity: target kW × duration of peak events. For demand charge management, 1-2 hours of duration is typically sufficient. 3. Apply round-trip efficiency (88-92% for lithium-ion): size the battery 10% larger than the calculated energy requirement.

Example — 500 kW peak shaving at a manufacturing plant:

Target reduction: 500 kW
Peak event duration: 2 hours (based on interval data analysis)
Battery size: 500 kW / 1,000 kWh (with 10% efficiency buffer: 500 kW / 1,100 kWh)

Installed cost (2025): $800-$1,200/kWh for C&I BESS
Total capital: $880,000-$1,320,000 (using 1,100 kWh at midpoint $1,000/kWh = $1,100,000)

Annual savings stack:
  Demand charge savings: 500 kW × $15/kW × 12 months = $90,000
  Capacity tag reduction: 500 kW × $60/kW-yr (PJM example) = $30,000
  TOU energy arbitrage: charge off-peak ($0.04/kWh), discharge on-peak ($0.08/kWh)
    1,100 kWh × $0.04/kWh spread × 250 days × 90% efficiency = $9,900
  Demand response revenue: 500 kW × $40/kW-yr (PJM Economic DR) = $20,000

Total annual value: $149,900
Simple payback: $1,100,000 / $149,900 = 7.3 years
With ITC (30% for standalone storage as of IRA): payback = $770,000 / $149,900 = 5.1 years

Decision thresholds:

• Payback < 5 years (with stacked value + incentives): strong economic case, proceed
• Payback 5-7 years: viable if aligned with sustainability goals or if demand charges are rising
• Payback 7-10 years: marginal, requires additional strategic justification
• Payback > 10 years: economics don't support investment without regulatory mandate

Demand Response Program Evaluation

Not all DR programs are equal. Evaluate on these dimensions:

3.3 Staggered Startup Protocol

The single lowest-cost demand charge reduction strategy — no capital required:

Problem: Morning startup creates a demand spike when HVAC, compressors, lighting, and production equipment all energize simultaneously between 5:30-6:30 AM.

Solution: Stagger equipment startup over a 60-90 minute window:

5:00 AM  — Lighting (50-100 kW)
5:15 AM  — HVAC pre-cooling/heating (500-800 kW, ramps over 30 min)
5:45 AM  — Compressed air system (200-400 kW, staged compressor starts)
6:00 AM  — Production Line 1 (300-500 kW)
6:15 AM  — Production Line 2 (300-500 kW)
6:30 AM  — Auxiliary systems, battery chargers, water heating

Result: Peak during startup drops from 2,200 kW (simultaneous) to 1,600 kW (staggered)
Savings: 600 kW × $15/kW × 12 months = $108,000/year at zero capital cost

Implementation: Program the building automation system (BAS) to enforce startup sequencing. Set hard interlocks that prevent the next system from starting until the prior system has reached steady state.

4. Market Analysis Framework

4.1 Regulated vs. Deregulated Strategy Map

4.2 Forward Curve Analysis

What the forward curve tells you:

• Market consensus on future energy prices (adjusted for risk premium)
• Seasonal price patterns (summer/winter spreads)
• Year-over-year price trajectory (escalation or decline)

What the forward curve does NOT tell you:

• Actual future spot prices (forwards are not forecasts — they include a risk premium)
• Short-term price spikes (forwards are averages, not tails)
• Regulatory changes, plant retirements, or transmission additions not yet priced in

Using forward curves for procurement decisions:

4.3 Capacity Market Exposure

In organized capacity markets (PJM, ISO-NE, NYISO), capacity charges are a significant cost component — $30–$120/kW-yr depending on the zone and auction results.

PJM Reliability Pricing Model (RPM):

• Auction held 3 years ahead of delivery year (Base Residual Auction)
• Incremental auctions adjust quantities closer to delivery
• Your capacity obligation is based on your PLC (Peak Load Contribution)
• PLC is set by your metered load during the 5 highest system coincident peak hours (5CP) in the prior delivery year

Managing capacity exposure:

1. Track PJM system peak alerts. PJM issues "hot weather alerts" and "emergency alerts" when system peaks are expected. Curtail discretionary load during these hours to reduce your PLC for the following year. 2. Install peak notification systems. Subscribe to PJM's demand response alerts. Deploy load curtailment controls that can drop 10-20% of facility load within 30 minutes of a peak alert. 3. Behind-the-meter generation. Running backup generators during coincident peak hours reduces your metered load and thus your PLC. Ensure generators are permitted for non-emergency operation and emissions-compliant. 4. Capacity tag trading. In some markets, capacity obligations can be traded or offset through financial instruments. Your supplier may offer capacity tag management as a service.

Example — capacity charge impact:

Facility peak: 5,000 kW
PLC (measured during prior year 5CP hours): 4,200 kW
PJM BRA clearing price for your zone: $85/MW-day

Annual capacity charge: 4,200 kW × $85/MW-day × 365 / 1,000 = $130,305/year

If you had curtailed 500 kW during the 5CP hours:
Reduced PLC: 3,700 kW
Annual capacity charge: 3,700 kW × $85/MW-day × 365 / 1,000 = $114,793/year
Savings: $15,512/year from 5 hours of load curtailment

5. Hedging Strategy Design

5.1 Hedging Instruments Available to C&I Buyers

5.2 Hedging Strategy by Risk Profile

5.3 Option Pricing and Evaluation

When buying call options to cap index pricing exposure, evaluate:

Option value = Max(0, Spot Price - Strike Price) × Volume

Cost: Premium per MWh × Contracted Volume
Annual premium for a $50/MWh cap on day-ahead pricing: $2-5/MWh (varies by market volatility)

Example — protecting 50,000 MWh annual index volume:
  Call option strike: $50/MWh
  Premium: $3/MWh
  Total premium cost: $150,000/year

  If spot averages $42/MWh: option expires worthless, total cost = $42 + $3 = $45/MWh
  If spot averages $65/MWh: option pays $15/MWh, effective cost = $65 - $15 + $3 = $53/MWh
  If spot spikes to $200/MWh (weather event): option pays $150/MWh, effective cap = $53/MWh

  Maximum effective rate: strike + premium = $53/MWh regardless of market price

When to use options vs. fixed contracts:

• Options when you want to participate in downside moves but protect against spikes
• Fixed contracts when the premium for options exceeds the cost of just locking in a fixed price (this happens when volatility is high and options are expensive)

---

6. Sustainability Procurement Alignment

6.1 Mapping Procurement to RE100 and SBTi

RE100 progress calculation:

RE% = (Renewable MWh procured) / (Total electricity consumption MWh) × 100

Acceptable renewable MWh sources (in order of additionality):
1. On-site generation (strongest claim)
2. Physical PPA with new project (strong additionality)
3. Virtual PPA with RECs from new project (good additionality)
4. Utility green tariff (varies by program design)
5. Unbundled RECs (weakest claim — RE100 tightening requirements)

SBTi trajectory alignment:

• SBTi requires absolute Scope 2 emissions reductions on a defined trajectory (typically 4.2%/year for 1.5°C alignment).
• Lock in long-term renewable procurement (PPAs) that deliver emission reductions year over year.
• Avoid procurement strategies that increase fossil dependence (long-term fixed contracts with fossil-heavy grid mix and no REC component).

6.2 Cost-Effective Sustainability Procurement Path

---

7. Multi-Facility Portfolio Optimization

7.1 Portfolio Aggregation Strategy

When to aggregate:

• 3+ sites in the same ISO/utility territory
• Total volume > 20 GWh/year (attracts competitive supplier attention)
• Sites have complementary load profiles (some peak summer, others peak winter)

Aggregation benefits:

• Volume leverage: 5-15% lower supply pricing than individual site procurement
• Load diversity: combined portfolio has higher load factor than individual sites, reducing supplier risk premium
• Administrative efficiency: single contract, single invoice, single relationship

When NOT to aggregate:

• Sites in different ISOs with different market structures (PJM and ERCOT should be procured separately)
• One site has unique requirements (e.g., real-time pricing needed for a demand response strategy) that would constrain the entire portfolio
• Sites have vastly different contract expiration dates (stagger expirations to avoid all-at-once recontracting risk)

7.2 Portfolio-Level Risk Metrics

Track at the portfolio level, not just site-by-site:

7.3 Site Prioritization for Demand-Side Investment

With limited capital for demand charge mitigation, prioritize sites using this scoring model:

Investment priority: highest composite score first. A site scoring >80 is a strong candidate for battery storage or demand response. A site scoring <40 has limited demand charge optimization potential — focus on supply-side procurement instead.

8. Natural Gas Procurement

8.1 Gas Procurement Structures

Natural gas procurement for C&I consumers (boilers, CHP, process heat, backup generation) follows similar principles to electricity but with distinct market mechanics.

8.2 Basis Differentials for Natural Gas

Natural gas prices vary by delivery point. Henry Hub (Louisiana) is the benchmark, but delivered cost depends on the basis differential between Henry Hub and your local city gate or utility delivery point.

Common basis differentials (approximate):

Key insight: A facility in New England on index pricing faces dramatically different winter risk than a facility in Texas. Basis in New England during a cold snap can exceed $15/MMBtu, tripling the delivered gas cost. New England gas procurement requires winter hedging with firm pipeline capacity or LNG backup — index pricing without protection is reckless in that market.

8.3 Gas-Electric Interdependency

For facilities with both electricity and natural gas loads, recognize the coupling:

• When gas prices spike, electricity prices spike. Natural gas is the marginal fuel

for electricity generation in most US ISOs. A $2/MMBtu increase in Henry Hub translates to approximately $10-$15/MWh increase in wholesale electricity prices (depending on the average heat rate of marginal gas plants, typically 7,000-8,000 BTU/kWh).

• CHP economics are gas-price dependent. A CHP system generating electricity at

a heat rate of 6,500 BTU/kWh has a fuel cost of $6.50 × gas price per MWh. At gas $3/MMBtu, generation cost is $19.50/MWh. At gas $8/MMBtu, generation cost is $52/MWh. If your grid electricity cost exceeds your CHP generation cost, run the CHP. If grid electricity drops below CHP cost (e.g., during spring shoulder months with mild weather and low grid demand), consider shutting down CHP and buying from the grid.

• Dual-fuel hedging: When hedging gas and electricity simultaneously, recognize

that fixing gas costs and leaving electricity at index (or vice versa) creates a cross-commodity basis risk. If gas prices drop but electricity stays high (due to transmission constraints or non-gas generation tightness), your gas hedge underperforms while your electric bill remains high. Consider hedging both commodities on a correlated basis — many energy suppliers offer combined gas+electric portfolio management.

9. Tariff Optimization in Regulated Markets

9.1 Rate Schedule Selection

In regulated markets, the available tariff options may seem limited, but switching between rate schedules can save 5-15% on the total bill without changing consumption.

Step 1: Identify available rate schedules for your demand level and voltage. Most utilities offer 2-4 rate options for large C&I customers:

• Standard demand rate (flat energy + demand charge)
• Time-of-use rate (lower off-peak energy, higher on-peak energy + demand)
• Real-time pricing pilot (if available)
• Interruptible service rate (lower cost, utility can curtail during emergencies)

Step 2: Model 12 months of actual interval data against each available rate schedule.

For each rate schedule:
  Monthly cost = Σ(energy_charge_component) + demand_charge + customer_charge + riders

Where:
  energy_charge_component = Σ(kWh_per_interval × applicable_rate_per_kWh)
  demand_charge = max(15-min kW interval in month) × demand_rate
  For TOU rates: separate on-peak demand charge may apply

Step 3: Compare annual totals.

Step 4: Evaluate non-financial factors.

• TOU: requires ability to shift load or accept higher on-peak costs
• RTP: requires market monitoring and tolerance for price volatility
• Interruptible: requires ability to curtail load on short notice (typically 30-60 min)

9.2 Rate Case Monitoring and Response

When to intervene in a rate case:

Rate case timeline (typical):

Month 0: Utility files rate case with state PUC
Month 1-2: Intervenors file to participate
Month 3-4: Discovery (interrogatories, data requests to utility)
Month 5-7: Intervenor testimony filed
Month 8-9: Hearings
Month 10-12: PUC issues order
Month 13-15: New rates take effect (may be retroactive to filing date)

What to challenge in a rate case: 1. Rate of return on equity (ROE): Utilities typically request 10-11% ROE. Current authorized ROEs are trending down (9-10%). Challenge excessive ROE requests. 2. Rate base additions: Utilities earn their ROE on their rate base (invested capital). Challenge excessive or imprudent capital investments included in the rate base. 3. Cost allocation between rate classes: Utilities allocate total revenue requirement across residential, commercial, and industrial rate classes. Ensure your rate class is not subsidizing residential or other classes above cost causation. 4. Rate design: Even if the total revenue is approved, fight for demand-based rate design (rewards load factor management) rather than pure volumetric rates (punishes high-consumption customers regardless of load shape).

10. Emergency Procurement Protocols

10.1 Supplier Default / Bankruptcy

If your retail energy provider files for bankruptcy or fails to perform:

Immediate actions (24-48 hours): 1. Verify your account status with the utility. If the supplier defaults, your account reverts to the utility's Provider of Last Resort (POLR) service or standard offer service. You will NOT lose power — the grid keeps delivering regardless of supplier status. 2. Determine the POLR rate. In most states, the POLR rate is set quarterly based on wholesale market prices plus a premium (10-20% above competitive supply). This may be higher or lower than your current contract rate. 3. Contact 2-3 alternative suppliers immediately. Explain the situation — they will offer expedited enrollment (5-10 business days vs. normal 30-60 day switch process). 4. Review your contract for supplier default provisions, including any deposits or prepayments that may be at risk in the bankruptcy estate.

Medium-term (2-4 weeks): 1. Execute a new supply contract with the best available alternative supplier. 2. File a claim in the bankruptcy proceeding for any prepayments, deposits, or damages. 3. Review your supplier qualification criteria — consider adding financial covenants (minimum credit rating, tangible net worth requirements) to future contracts.

10.2 Force Majeure Events

When a force majeure event (natural disaster, grid emergency, pandemic) disrupts your energy supply or operations:

Assessment framework:

10.3 Contract Termination Decision Matrix

When evaluating whether to terminate a supply contract early:

Early Termination Fee (ETF) = Σ(remaining months × monthly volume × |contract price - current market price|)

If contract price > current market:
  You owe the supplier (you're paying above market)
  ETF = remaining months × volume × (contract price - market) × discount factor

If contract price < current market:
  Supplier owes you (you have a favorable contract)
  You would NOT terminate — the contract is in-the-money

Decision: Terminate if ETF < cumulative savings from alternative contract + risk reduction value

Example — mid-term exit evaluation:

Current contract: $0.062/kWh, 18 months remaining, 50 GWh remaining
Current market: $0.055/kWh (market has dropped since contract signing)
ETF: 50,000 MWh × ($0.062 - $0.055) = $350,000

Alternative contract: $0.054/kWh for 18 months
Savings from alternative: 50,000 MWh × ($0.062 - $0.054) = $400,000

Net benefit of termination: $400,000 savings - $350,000 ETF = $50,000

Decision: Marginal. Factor in:
  - Renegotiation risk (can you lock $0.054 before market moves?)
  - Administrative cost of switching suppliers
  - Relationship cost with current supplier
  - If net benefit < $100K, generally not worth the disruption
