So far so good on power supply

Demand (solid blue line) is comfortably below available supply (top line). As part of today's Flex Alert, state power officials are asking people to turn off all unnecessary lights, postpone using appliances until after 6 p.m., and turn air conditioner thermostats up to 78 degrees. Demand for power reached 46,847 megawatts on Monday, the highest so far this year. The heat wave is expected to continue through the week, with some relief by the weekend. Of course, that's what they said last weekend.
