Here in Colorado we have net metering, so two meters aren't needed. If my solar generates more than I use the excess is sent back to the grid, "State 3" in your post, I sell my electricity back to Xcel at wholesale
prices, not what I pay if I get the power from the grid, "State 1" from your post. Lets say I need power from Xcel, I would pay them (for simplicity) 10 cents per kw, but if I generate more on a sunny day I sell it back to them for 6 cents per kw. Please point out to me how are they getting screwed again?
Us fine folks here in Colorado passed a law several years ago that 20% of electricity has to come from renewable resources by 2020
, so Xcel would benefit from having more people getting solar on their houses, but they want to have the generation facilities to keep their monopoly.
Plain and simple, this is just a money grab by Xcel as they are going for the triple bonus of not having to generate as much electricity (less money spent on coal), getting a "connection fee", and getting closer to the requirement of 20% renewable without any capitol outlay.
I think most all power companies are scared that their monopoly on electricity production and distribution is in jeopardy with advances and the new smart grid. Power companies are the single biggest roadblock to any advancement of our aged and ailing electrical grid. They refuse to look at any other way of doing business other than having huge power plants and huge power lines feeding. (sound familiar? Music industry anyone?) I realize that there will always be a need for power plants and lines, but there are many ways to get the job done better.
I am guessing that you work for a power company?
