We all have our stories of disappointing SCE policy, but I occasionally find examples from other states that show we should be grateful for the policies in place in CA, imperfect as they are.
Net metering is allowed in 36 states. It is not an option for the 9 million people served by TVA.
The reason offered by the nation’s largest public power utility is that net metering is not allowed by the law that created TVA. The utility generates electricity and sells it to 155 local power companies (LPCs). The LPCs create and maintain the distribution system and sell the power they bought from TVA to us. The contractual arrangement with TVA is a “buy all, sell all” whereby the LPCs can purchase electricity only from TVA. This effectively forbids net metering, because TVA interprets that as the LPC buying power from the owner of the PV array.
Thus, any grid-tied solar system within the TVA region must have dual metering, one to measure power coming off the grid, another to measure power going to the grid. The arrangement with TVA is likewise “buy all, sell all” in that you have no choice but to sell all the power you generate to TVA, then you buy back whatever you actually consume. If you are able to get in under TVA’s “cap” for its Green Power Providers incentives program, you will be paid the retail rate for the power you generate. All others are paid the lower wholesale rate. Everyone pays the retail rate for what they consume. So the home or business owner pays for the PV system, and TVA makes money on the power generated by it.
