US Power Grid May Become Unreliable This Summer, Watchdog Warns
Parts of America could face difficulties in meeting electricity demand during the summer season, with renewable energy sources like wind and solar power posing a potential risk to reliable power supply, according to a report by the North American Electric Reliability Corporation (NERC).
Elevated risk means there is “potential for insufficient operating reserves” when the region faces above-normal demand conditions. Such regions include parts of Louisiana, Texas, New Mexico, Arizona, California, Illinois, and Iowa. The determination of elevated risk is based on various factors, including potential low wind or solar energy conditions that could lead to a lower electricity supply.
The North American power bulk power system (BPS) is made up of six regional entities—Midwest Reliability Organization (MRO), Northeast Power Coordinating Council (NPCC), ReliabilityFirst (RF), SERC Reliability Corporation (SERC), Texas Reliability Entity (Texas RE), Western Electricity Coordinating Council (WECC)—with elevated risk upcoming in certain regions.
However, if MISO were to face above-normal peak demand conditions at a time when wind and solar output is lower than expected, it could be “challenging” for the transmission organization to meet demand.
