NERC Issues Grim Outlook for Bulk Power System Winter Reliability
NERC Issues Grim Outlook for Bulk Power System Winter Reliability (by Sonal Patel, Power, November 18, 2021.)The North American Electric Reliability Corp. (NERC) is warning that much of the central U.S.—a region that stretches from the Great Lakes into southern Texas—may face critical power deficiencies during extreme winter weather conditions over the next three months. Natural gas supply disruptions and low hydropower conditions could also imperil power reliability in New England and the West, it said.
In its Nov. 18–issued 2021–2022 Winter Reliability Assessment, the nation’s designated Electric Reliability Organization (ERO) urged generators across the U.S. to take proactive steps to prepare for an eventful winter and keep communications open with grid operators.
NERC also called on grid operators to prepare and implement cold weather operating plans, conduct drills, and poll generators for fuel and availability status. Load-serving entities should review critical loads to prevent disruptions, and regulators should support requested environmental waivers, it said.
A Cold, Hard Outlook
The ERO’s dire report echoes its May-issued summer assessment, when it warned of “elevated risks” for energy emergencies in Texas, New England, in the Midcontinent Independent System Operator (MISO) territory, and parts of the West. In its bulk power system (BPS) reliability assessment for the next three months—December 2021 through February 2022—NERC suggests extreme weather risks, including soaring peak demand or generator outages that exceed forecasts, “can be expected to cause energy emergencies” in regions that have previously suffered cold-weather reliability debacles. These include MISO, the Southwest Power Pool (SPP), and the Electric Reliability Council of Texas (ERCOT)...
