Moody’s concludes: mass grid defection not yet on the horizon

Yes, solar power systems are getting cheaper and battery storage is improving. The combination has many folks worried (or elated) about the future prospects of grid-based electric utilities when consumers can get the power they want at home. (See Lynne’s post from last summer for background.)

An analysis by Moody’s concludes that battery storage remains an order of magnitude too high, so grid defections are not yet a demonstrable threat. Analysis of consumer power use data leads them to project a need for a larger home system than other analysts have used. Moody’s further suggests that consumers will be reluctant to make the lifestyle changes–frequent monitoring of battery levels, forced conservation during extended low-solar resource periods–so grid defection may be yet slower than the simple engineering economics computation would suggest.

COMMENT: I’ll project that in a world of widespread consumer power defections, we will see two developments to help consumers avoid the need to face forced conservation. Nobody will have to miss watching Super Bowl LXXX because it was cloudy the week before in Boston. First, plug-in hybrid vehicles hook-ups so the home batteries can be recharged by the consumer’s gasoline or diesel engine. Second, home battery service companies will provide similar mobile recharge services (or hot-swapping home battery systems, etc.) Who knows, in a world of widespread defection, maybe the local electric company will offer spot recharge services at a market-based rate?

  1. Don’t be ridiculous. Grid electricity is a bargain. Trying to replace it with solar panels (we have had no sunshine for the last 48 hours daylight was iron gray with freezing rain) and keeping the car parked so we can keep the lights on is absurd. BTW, the idea of having to run my own diesel electric generators is not comforting. Do I get to hire an oiler.
