Following a relatively calm weekend, SPP has again declared a resource advisory for Monday across its 14-state balancing authority area because of expected high loads and concerns over generation availability.
The advisory, which does not require public conservation, is effective from noon to 10 p.m. CT. Under the advisory, the BA can commit units earlier than under standard day-ahead market procedures and commit resources in reliability status.
The RTO’s most recent conservative operations and resource advisories expired as scheduled Thursday night.
The National Weather Service says an approaching cold front will cool down parts of the Midwest by late Sunday into Monday, but “searing heat” will remain in the Southern Plains into early this week.
A persistent high level ridge from the Southern Plains to the Southeast has resulted in record-breaking triple-digit temperatures as high as 115 degrees Fahrenheit in Oklahoma and Texas. Highs well above 100 F are expected in the early part of the week and for the foreseeable future. (See related story, ERCOT Sets Record for Demand … Again.)
SPP set a new mark for peak demand last week at 53.2 GW on July 19. It was the fourth time this year the RTO has recorded a new high. The record before this year was 51.04 GW, set last July.
