At best, that will mean summer "brownouts," voltage reductions that dim lights and slow appliances.

But Potomac Electric, like other utilities, made do with voltage reductions.

Essentially, the power savings were achieved with a combination of frequency (through adjusting multipliers) and voltage reduction.

The 500 KV transmission system was not completed throughout the whole state back in the 1960's and 70's, so we saw more voltage reductions then.

But they managed to get through the afternoon with voltage reductions and the help of the public cutting consumption.

"There is a possibility for voltage reductions or other emergency measures, because there's a greater chance we're going to experience shortages," Mr. Shepardson said.

New Jersey has already experienced several voltage reductions this summer.

A technique to prevent this is load shedding by rolling blackout or voltage reduction (brownout).

A phenomenon known as load diversity plays a role in voltage reduction and can counteract its effects on occasion.

I know they've done clock gating; but voltage reduction?
