Welcome to EPRI's Resource Adequacy Center

What is Resource Adequacy?

Resource adequacy (RA) is an assessment of whether the current or projected resource mix is sufficient to meet capacity and energy needs for a particular grid. The resource mix refers to the mix of supply-side generation, such as solar or nuclear paired with energy storage, and demand-side flexibility, such as demand response and energy efficiency. RA assessments are used to identify potential shortfalls in the availability of resources across different time frames, from long-term planning (5 to 20+ years) to seasonal and day-ahead assessments. As the RA look-ahead time approaches real-time operations, options to address identified shortfalls become fewer and more expensive.

The purpose of this site is to bring together information to help those trying to assess adequacy in this context. It draws on a wide range of work that EPRI and the industry has conducted in response to the challenge of the emerging grid. We welcome your feedback on how to make this increasingly useful to support you and your decisions.

This resource center focuses on basic RA concepts, methods and metrics and more application focused topics such as study tool choices and methods to assess the impact of certain technology classes. Each of the links below brings you to a dedicated section to each issue facing practitioners when conducting adequacy studies.

-Resource adequacy is a fundamental part of grid planning and operational planning. The challenge involved with understanding adequacy is increasing as new technologies join the generation mix. Technologies such as wind, solar, short-duration energy storage, distributed resources and Power-to-X all have different constraints on their availability to conventional thermal generation or hydro power. Meanwhile, customer behavior is changing and the role of electricity in society is evolving as the key vector for decarbonization.
