Power demand sets weekend record

The heat wave seems to have toppled at least one power demand record. A spokeswoman for the Independent System Operator that runs the New England grid – ISO New England – said preliminary results for Saturday showed a peak demand in the region of 24,653 megawatts. If that holds, it will set a new record for weekend power demand.

It was also more power than ISO New England had predicted it would need. Weekend power demand is typically lower than weekday.

ISO New England also reported that its preliminary data for the weekday portion of the heat wave showed peak demand came on Friday at 27,377 megawatts. If that holds it will be the fourth highest on record. The highest was 28,130, coming during a heat wave on Aug. 2, 2006.
