ATLANTA – Adequate capacity resources are projected to meet increasing peak demand over the next 10 years, NERC finds in its recent long-term assessment. The addition of large amounts of utility-scale wind, solar and natural gas generation combined with a major influx of energy storage technology requires continued enhancements to system planning and operations.
More than 330 GW of solar and wind capacity are planned for installation through 2029, according to the 2019 Long-Term Reliability Assessment. Meanwhile, the rate of transmission infrastructure development needed to support these variable resources and system expansion has declined from nearly 40,000 circuit miles earlier this decade to less than 15,000 circuit miles over the next ten years, the assessment finds.
