California's gas-fired power plants experienced a surge of curtailments and spiking emissions during last summer's heat wave, according to the report from an in-state environmental coalition.

MISO’s system can operate on 50% renewable generation if the RTO greenlights dramatically more transmission and its members embrace new technologies.

EIM transfers out of CAISO were on the upswing in March, re-establishing a pattern first seen last spring with California’s growing solar surpluses.

CAISO is curtailing an increasing volume of renewable generation this spring as the ISO sees its “duck curve” already dipping to levels forecast in 2021.
