First off, it said during the install. So evidently it wasn't load related anyway.

Second, I used to live in a little town of well under 50k people. The local coop gave a couple hundred dollars in rebates for the installation of load management on their water heaters. I'd expect this would get solved in basically the same way. The total gwh isn't a problem, the gw is, and that's fairly easy to solve problem.
