Renewable Curtailment and Forecast Variance Dispatch

Role: Senior Renewable Energy Market and Generation Analytics Lead specializing in ERCOT/CAISO nodal dispatch and wind/solar forecasting.

Context

• Generation Portfolio: {{asset_portfolio}}
• Operational Horizon: {{forecast_period}}
• Curtailment Volume: {{curtailment_mwh}}
• Pricing Hub/Node: {{market_pricing_node}}
• Financial Imbalance Exposure: {{imbalance_penalty_estimate}}
• Operational Adjustments: {{mitigation_actions}}

Task

Compose an actionable operational email to generation asset managers and the real-time energy trading desk outlining why generation diverged from forecast, quantifying curtailment exposure at the node, and confirming adjustments to bidding or plant setpoints.

Method

1. Contrast day-ahead weather and generation models against real-time generation profiles for {{asset_portfolio}}.
2. Quantify the exact volume of lost generation represented by {{curtailment_mwh}} across {{forecast_period}}.
3. Map the volume variance against nodal pricing dynamics at {{market_pricing_node}} to explain {{imbalance_penalty_estimate}}.
4. Differentiate between economic curtailment (negative nodal pricing) and physical reliability curtailment (interconnection congestion).
5. Review the feasibility and timing of proposed {{mitigation_actions}} such as automated battery storage absorption or revised day-ahead bidding parameters.
6. Synthesize the operational takeaways into an executive morning/shift briefing email tailored for rapid commercial comprehension.
7. Conclude with required sign-offs before next scheduling gate closure.

Constraints

• MUST express all volumetric figures in MWh and financial metrics with explicit currency markers.
• MUST differentiate between forecast error volume and ISO-instructed curtailment volume.
• MUST NOT make unsupported forward pricing predictions outside {{forecast_period}}.
• Email length must not exceed 300 words total.

Output format

• Subject: Forecast Deviation & Curtailment Brief: {{asset_portfolio}} [{{forecast_period}}]
• Commercial Summary: 2 sentences defining total MWh lost and net financial exposure.
• Key Analytical Drivers: 3 concise bullet points covering weather shift, nodal congestion, and ISO dispatch instructions.
• Trading & Plant Directives: Numbered list specifying real-time dispatch adjustments from {{mitigation_actions}}.
• Gate Closure Warning: 1 sentence stating the immediate scheduling deadline.

Self-review

• Ensure {{market_pricing_node}} and {{imbalance_penalty_estimate}} are prominently highlighted.
• Check that the distinction between weather-driven variance and grid curtailment is unambiguous.
• Verify adherence to the strict 300-word limit.
