44 views Source: San Angelo Standard-Times The operator of Texas' power grid is facing fresh skepticism after the grid faced a near emergency Tuesday – just two months since February's deadly power outages. Even though it was a mild spring afternoon with highs in the 70s and 80s, power generation came close to falling short of demand Tuesday, leading the Electric Reliability Council of Texas to call for conservation. In the end, no blackouts were ordered as electricity use fell in the evening hours. However, the failure to accurately predict power generation amid warmer-than-expected temperatures – even though the agency knew that 25% of the grid's power generation had been shut down for maintenance – brought new criticism for ERCOT, which has faced much of the blame for widespread power outages during February's winter storms.
