The state's electric power grid operator says Texas needs more generating capacity if it's to avoid repeats
of last February's rolling blackouts and the summer's power supply crises.
In statements issued Thursday, the Electric Reliability Council of Texas says extreme conditions this winter could mean a worst-case of demand for 60,000 megawatts with generation dipping to about 57,000 megawatts.
It also said its reserve generating capacity "will likely fall below the minimum target beginning next summer."
It cites decisions to mothball some outdated generation units, delays in planned generation and higher demand expectations.
ERCOT expects to have a 12 percent margin in reserve generating capacity in the next two summer peak seasons.
That's short of the 13.75 percent margin it believes ensures reliable power during higher-than-normal temperatures and generator outages.
