It’s not necessarily a bad thing to have too much capacity to deliver electricity. Remember the rolling blackouts?
Industry experts had projected a 2.1 percent increase in peak load for the Texas grid this year, but so far the increase has been less than half that.
Electric Reliability Council of Texas director of system planning Warren Lasher says it’s mostly about the weather.
“Especially in the Houston area, this has been a fairly mild summer,” Lasher says. “In other parts of Texas, it’s been rather warm, but it's the cumulative impact of the weather across the region which results in our peak load.”
Lasher says ERCOT projects up to a decade in advance and it’s always good to have plenty of electricity available.
He says, “If you build more capacity than you need, then that capacity will go unused. However, loads continue to grow in the state, the economy is growing at a good pace.”
