Meanwhile, the low electricity prices of recent years — a function of cheap natural gas — and small profits have discouraged companies from investing in new power plants. ERCOT, which oversees about 90 percent of the state’s power grid, said power reserves that are called on when demand peaks on the hottest summer days have shrunk to the lowest levels since Texas deregulated power markets in 2002.
