Colorado Resource Adequacy
Overview
The Colorado Resource Adequacy Act of 2023, in House Bill 23-1039, article 43, requires resource adequacy reports to be posted on load-serving entities' websites using a common uniform resource locator convention, as determined by the Colorado Energy Office, and include a list of categories of information.
Article 43 on Electric Resource Adequacy finds that:
- Maintaining electric reliability and resource adequacy in the transition to clean energy is of great importance to Colorado and its electricity customers;
- The development of a comprehensive resource adequacy reporting structure for all wholesale and retail load-serving entities will help position Colorado utilities for entry into an optimal organized wholesale market, as defined in section 40-5-108 (1)(a), that will increase the efficient and cost-effective use of capacity resources and enable resource adequacy across a broader footprint throughout the state;
- The North American Electric Reliability Corporation has identified resource adequacy and energy risks in the western interconnection of the electric power grid; and
- Colorado can begin to address these risks by adding resource adequacy reporting requirements for all load-serving entities to help measure the sufficiency of reliable and resilient electric service to all Colorado electricity customers.
Requirements
- A native load forecast;
- Nameplate capacity and accredited capacity by individual resource, including renewable energy resources and storage;
- Identification of any accredited capacity attributable to distributed generation resources, including energy storage;
- Identification of any demand response that the load-serving entity relied upon for resource planning purposes or uses to reduce peak load;
- Identification of the target planning reserve margin;
- Identification of the forecasted planning reserve margin;
- Identification of the total accredited capacity and any formulas or assumptions used to calculate the accredited capacity; and
- Identification of any excess capacity or resource needs and of plans to mitigate forecasted shortfalls prior to experiencing peak load supply conditions that were forecasted in calculating the planning reserve margin.
