Later in the article, they mention the "capacity market" that Texas does not have, but other states do have. In NY, we call that ICAP. ICAP pays generators for being capable of delivering energy, and bidding in the daily markets. The purpose of ICAP is to prevent bad guys like Enron from boosting prices by withholding capacity, or faking malfunctions. If ICAP payments are substantial, power generators want the payments badly. The key relevant here is, what do the power plants need to do to qualify for ICAP payments? Thinks like winterproofing for example.
Critics say ICAP pays providers for doing nothing, and Texas doesn't have it. But I agree with the WSJ that the lack of ICAP in Texas is a major blunder.
