rules change

The porposed amendment seeks to amend the WESM Rules and various WESM Manuals to:

• Apply Forecast Accuracy Standards (FAS), in lieu of Dispatch Conformance Standards (DCS), to Variable Renewable Energy (VRE) generating units that elect to operate as Scheduled Generating Units;
• Enable offer-based participation and greater responsiveness of VRE generators to market price signals;
• Allow VRE generators to manage exposure to negative prices and reduce uneconomic dispatch;
• Maintain forecast accountability through the existing FAS framework; and
• Implement the necessary amendments to the WESM Rules and relevant WESM Manuals to give effect to the proposed changes.
