As the power supply landscape continues to move toward renewables, can microgrids boost reliability? 

According to the “2023 Summer Reliability Assessment,” published in May 2023 by the North American Electric Reliability Corporation (NERC), two-thirds of North America is at risk of energy shortfalls this summer during periods of extreme demand.

While there are no high-risk areas in this year’s assessment, the number of areas identified as being at elevated risk has increased. The assessment finds that, while resources are adequate for normal summer peak demand, if summer temperatures spike, seven areas — the U.S. West, SPP and MISO, ERCOT, SERC Central, New England, and Ontario — may face supply shortages during higher demand levels.
