The state's electric reliability council is warning about the possibility, even with un-mothballing two old coal-fired plants.
And, 2012, actuually, wasn't that bad a summer. We don't have to be as bad as 2011 for us to face problems.
And, speaking of 2011, don't forget, these electric plants need water. If the drought is worse this year than 2012, even if it doesn't approach 2011, that's an additional complication.
That said, we progressives like to deride Dick Cheney for not talking about conservation. Will you raise your A/C thermostat, even before an official ERCOT warning?
