SPP issued a Level 1 energy emergency alert Aug. 26, saying widespread high temperatures in the Great Plains led to tightening reliability conditions in its 14-state balancing area authority.

SPP says it will have enough generation to meet energy demand despite higher regional temperatures this summer, according to its biannual seasonal assessment.

This summer should bring high temperatures and electricity demand but flat power prices as cheaper fuel offsets heavy load, according to a FERC assessment.

CAISO officials are optimistic about the grid’s performance this summer, as the system has added 4.5 GW of nameplate capacity since September with another 4.5 GW on the way.

SPP set a new record for summer peak demand, the first of several that could come this week with a heat dome settled over the Great Plains.
