Commercial PPA Indexation and Tariff Risk Assessment

Role: Senior Energy Origination & Structured Pricing Specialist with fifteen years of experience in wholesale power structuring.

Context

• Energy Seller: {{utility_provider}}
• Off-taker Profile: {{offtaker_profile}}
• Tariff Model: {{proposed_tariff_structure}}
• Market Benchmark: {{wholesale_market_index}}
• Agreement Duration: {{contract_term_years}}
• Curtailment Terms: {{curtailment_provisions}}

Task

Deliver an end-to-end pricing structure analysis for {{utility_provider}} evaluating the revenue viability and downside risk of {{proposed_tariff_structure}} over {{contract_term_years}} for {{offtaker_profile}}.

Method

1. Deconstruct {{proposed_tariff_structure}} into base load, peak spread, and capacity charge components.
2. Model the correlation between {{wholesale_market_index}} fluctuations and customer net payment flows.
3. Quantify volumetric risk under the operational constraints of {{curtailment_provisions}}.
4. Calculate the unhedged price exposure across extreme power spot price scenarios.
5. Evaluate credit and default risk implications specific to {{offtaker_profile}} under high-tariff periods.
6. Compare implied gross margins against standard utility hurdle rates.
7. Formulate specific indexation floor and ceiling recommendations to protect sales profitability.

Constraints

• Base all risk scoring on the defined parameters for {{wholesale_market_index}}.
• MUST evaluate both merchant upside sharing and downside floor protection.
• MUST NOT suggest contract modifications that alter {{contract_term_years}} without quantitative justification.
• Maintain an objective, risk-adjusted underwriting tone.

Output format

• Executive Summary: Exactly 3 bullet points summarizing pricing viability.
• Tariff Risk Matrix: 4 named rows evaluating Margin, Volume, Indexation, and Counterparty risks.
• Sensitivity Analysis: 3 scenarios (Base, High Spot Spike, Deep Slump) with margin impact.
• Pricing Guardrail Recommendations: Maximum 4 actionable contracting rules.

Self-review

• Confirm all 6 context variables are explicitly referenced.
• Verify exactly three scenarios are detailed in the sensitivity section.
• Check that indexation mechanics directly reflect {{wholesale_market_index}}.
