The cash, and profit from these operations doesn't fall within the regulations of state governments. AES Energy Storage, with the same corporate parent -- AES (AES) as Indiana's IPALCO utility -- has a 32-Mwatt battery in West Virginia controlling the output of a wind farm. It makes money.
Not every utility company is on board with this. Municipally owned CPS Energy in San Antonio is trying to cut what it pays homeowners for solar power, citing increased costs. Most of Texas' grid is isolated from that of the rest of the country, as seen in this Google Sites map.

Pacific Gas & Electric (PCG) is trying to fight off a challenge to its monopoly status in San Francisco from the municipally owned CleanPowerSF.
