PJM power demand hits preliminary winter record
PJM has hit a preliminary record for winter demand with a peak load of 145,000MW at 8.15am on January 22, driven by extreme cold nationwide.
In a statement PJM said that this exceeds the all-time winter instantaneous peak of approximately 143,700MW, set in February 2015, pending the availability of verified metered load data. The grid operator added that its generation fleet and transmission system performed reliably while supporting neighboring systems on all fronts with nearly 8,000MW exported.
PJM’s Mike Bryson, senior vice president for Operations, said PJM and its member companies took a number of steps before the onset of the cold that helped prepare the system for the most difficult periods Tuesday and Wednesday. These included:
- cold weather advisory and cold weather alert: helps members get engaged with preparing for the cold weather
- conservative operations declaration: helps generators line up gas purchases with the gas market, especially over holiday weekends
- maintenance outage recall: maximizes generator availability by requiring generators that were out for maintenance to come back in service
- low voltage alert: maximizes transmission system capability
- maximum generation alert: issued Tuesday to alert neighboring regions that electricity exports from PJM may be curtailed, if necessary.
