Dive Brief: The grid operator for most of Texas expects there will be sufficient generation to meet peak loads this summer, but on Thursday detailed three low-probability scenarios where extreme weather could lead to blackouts. The new level of detail on scenarios with a 1% chance of occurring is an attempt by the Electric Reliability Council of Texas (ERCOT) to "restore trust" following February's winter grid collapse and communication failures, according to Warren Lasher, senior director of system planning. ERCOT is bracing for record-breaking electric demand this summer, officials said, due to anticipated heat as well as population and economic growth in the state. But the grid heads into the warmest months with a 15.7% reserve margin, only slightly below the ideal level, they added.
