A long hot summer?

Could be:

Higher temperatures and increased demand for electricity Monday, perhaps due to a rebounding economy, drove electricity reserves below 7 percent, prompting a Stage 1 emergency.

The Independent System Operator, which manages much of the state's power grid, lost two plants that supplied about 800 megawatts early Monday, then saw electricity use surpass forecasts by 1,100 megawatts, mainly due to higher than average temperatures, said ISO spokeswoman Stephanie McCorkle.

Note the reference to the rebounding economy's potential to drive electrical demand. Unfortunately that cuts both ways - lack of power can throttle the economy.

And this time they won't be able to blame Enron.
