PRINCETON, N.J., April 16, 2009 — Reliably integrating larger amounts of wind, solar, and other variable generation into the bulk power system will require changes to the way the system is planned and operated, stated the North American Electric Reliability Corporation (NERC) in the special report “Accommodating High Levels of Variable Generation,” released today. The report highlights transmission additions and reinforcements, better forecasting of variable generation output, and access to flexible grid resources (including customer participation in targeted demand management, plug-in hybrid electric vehicles, and large-scale electricity storage) as key contributors to reliably integrating variable resources into the system.
