Clean energy is taking over the Texas grid. State officials are trying to stop it.

Summary

Wind, solar, and nuclear energy contributed over 40% of the Texas' power in 2022. Texas wind turbines and solar panels have strong "complementarity," meaning deficiencies in one source are generally compensated by gains in another, smoothing electricity supply and lowering the demand for additional generators facilitating grid integration of intermittent energy sources. Since 2006, Texas coal has lost almost half its share. Cheap natural gas from hydraulic fracturing was outcompeting coal, and coal power stations had to modify their equipment to meet tighter mercury restrictions, rising electricity production costs. Wind and solar, with low construction prices, fast build periods, and no fuel costs, dominate Texas's freewheeling energy sector. However, some politicians are now seeking to shift the balance back toward fossil fuels. Texas lawmakers banned fossil fuel boycotters from doing business with the state's retirement and investment funds last year. Texas Lt. Gov. Dan Patrick wants additional funding for natural gas-fired electricity. Wind and solar power are expanding, but they are intermittent, so regulators want adequate dispatchable electricity like natural gas to ramp up on overcast days. A new credit structure would encourage more dispatchable plants to come online and save some failing generators, but power generation costs would rise.
