[Vo]:1200 MW compressed air storage

2015-12-10 Thread Jed Rothwell
This describes 1200 MW for 48 hours, in compressed air stored in salt
caves. It resembles pumped hydroelectric storage.

Just a thought:- I wonder if an arrangement could be made with some industries
(e.g. Aluminium producers) where they took a lot of cheap power when it was
available and less, expensive power, when it wasn't. IOW a form of demand side
management. It could be a way of mitigating the requirement for storage, making
renewables more useful. Perhaps they already do this?

I expect some power companies have arrangements like that.

In Atlanta now that we have smart meters, Georgia Power offers a discount
"nights and weekends" rate. The catch is, they charge a lot more during
peak hours in the summer. The rate is 5 cents/kwh off-peak, and 20 cents at
peak.

"Georgia Power's peak period is from 2-7 p.m. on summer weekdays for the
months June - September."
