Why not put up some solar panels, get a good set of batteries and an inverter? That way, they can't say a fargin' thing. If only the A/V equipment is on the solar setup and they can't prove it's connected to the grid,....
If I was in that part of the country, I'd be on solar power so fast it would make peoples' heads spin. I'm so sick of WE Energies (Wisconsin) I'd do almost anything to not pay a utility. They raised our residential rates close to 45% in the last 7 years, sold a nuclear power plant for $985 Million, told us to use less power and now that they aren't selling as much energy, they want to raise our rates 7% because they said they have to offset the fixed costs and that commercial and industrial customers aren't buying as much. They also said their pension fund payments have increased and need to provide a better return for their shareholders.
