Although the eclipse will reduce solar power generation, PJM Interconnection expects no power grid reliability issues in its footprint, which includes 13 states and the District of Columbia and 65 million people. It will use its sufficient reserves for replacement generation.
“Certainly, this is an unusual solar event, but as far as potential impacts to the grid, PJM and its members are prepared,” said PJM President and CEO Andrew L. Ott. “While this is an anticipated event, we routinely plan and prepare for unpredictable events or things that can’t be forecast far in advance, such as severe storms and heat waves.”
Certain states will experience a greater impact, including North Carolina, which will experience a complete solar eclipse, and New Jersey, which has more photovoltaic solar generation than most other the states served by PJM.
PJM will ensure sufficient resources are ready to replace any solar generation loss and will refine its analysis prior to the eclipse to factor in the latest weather forecasts.
