I signed up for Solar back in April via SolarCity. They're not installing until december. Glad I signed up for it with the rate hike notice I got. But beware that National Grid (at least where I live) is capping how much power I can generate so they limited the size of my SolarCity install. Transformer couldn't handle as much intake as I was able to generate. There's a big battle brewing between these electric companies and the solar companies.
The utilities have a huge advantage in this fight: they own the network. It's going to take state legislatures and utilities commissions to move the utilities, and it will be a state-to-state, hand-to-hand battle.
There is no federal preemption available here, as the line between retail and wholesale power is very clearly drawn. The
D.C. Circuit recently threw out FERC Order 745. Quoting from the court's opinion:
The rule seeks to incentivize retail customers to reduce electricity consumption when economically efficient. Petitioners complain FERC’s new rule goes too far, encroaching on the states’ exclusive jurisdiction to regulate the retail market. We agree and vacate the rule in its entirety.
Overturning this rule was an important win for "big power" -- the fight was led by
EPSA, the trade organization of the independent power producers, who have a lot to lose if DR can be subsidized to knock down super-peak prices. The DC Circuit has jurisdiction over all the federal agencies, so its opinion on a FERC matter like this applies through the U.S., much as a SCOTUS ruling would. (FERC did not appeal this order to SCOTUS.)
I bring up this DR issue because DR and solar have a lot in common -- the major difference being that solar can result in net injections at a customer site, while DR is limited to reducing load. The rate-making issues are very similar, though.
