Grid operator PJM issues maximum generation alert for Monday amid heat wave
June 23 (Reuters) - Grid operator PJM Interconnection has issued an alert for Monday asking power generators to be ready to operate at maximum capacity if needed, as hot weather continues throughout the eastern U.S. region the grid operator serves.
PJM expects its electricity needs to reach 160,000 MW on Monday, 158,000 on Tuesday and 155,000 on Wednesday, it said.
The alert is aimed at transmission and generation owners who can schedule maintenance work accordingly, and also signals to neighboring regions that PJM power exports may need to be curtailed, the grid operator said.
A hot weather alert is in effect through June 25 for PJM's entire service area, which includes all or parts of 13 states including New Jersey and Illinois plus the District of Columbia, ahead of an expected extended heat wave.
Major cities across the U.S. are preparing for extreme temperatures caused by a heat dome that hit the U.S. Plains on Friday and is expected to expand to much of the rest of the country over the coming days.
