ERCOT and Reliant urge Texans to conserve power amidst extreme heat wave.

Texas' grid operator, ERCOT, is urging residents to conserve energy between 4 p.m. and 8 p.m. on Tuesday due to soaring demand caused by extreme heat. ERCOT expects energy demand to hit a record high of 81,230 megawatts at 4 p.m. due to an atypical number of power plants being offline and wind turbines producing less power. The state is not in an emergency situation, but ERCOT is asking for voluntary conservation to ensure a smooth power supply. The extreme heat is worsened by climate change, and ERCOT recommends raising thermostats, refraining from running large appliances, and turning off unneeded lights and appliances.
