>Wholesale power prices on Texas’ main power grid hit the ceiling price of $9,000 per megawatt hour for parts of five straight days. That was exponentially higher than the average price, which was $21.18 per megawatt hour in 2020, according to the Electric Reliability Council of Texas, or Ercot, the nonprofit that controls the grid.
