Visual Primer: Growing Share of Intermittent Generation Prompts Closer Scrutiny of Potential Resource Adequacy Issues

Evolving electric system reliability needs that stem from the anticipated unprecedented growth in intermittent resources have prompted a closer scrutiny of resource adequacy (RA) issues. The increasing share of renewables to facilitate a lower-carbon grid, coupled with fossil generation retirements and increased demand for electrification, pose emerging challenges to the ability of system operators to meet reliability requirements. RA ensures that the planned resource mix is sufficient to meet the future system capacity needs and maintain grid reliability.
