Hi All, Following this post with much interest, as this affects everyone that wants to reduce reliance on a utility grid that is already overburdened, If TOU metering was done away with, it would eliminate "buy low and sell high", which is a "wash" when you consider battery replacement cost (due to excessive cycling). GTBB is an excellent way for individuals to "do their part" in conserving energy. The fact that utility companies are putting up such a battle is indicative of one thing.....money (is there any other motive?). Everyone concerned should contact their lawmakers in Congress to pass a federal law so these utility companies will stop obstructing clean energy.

Or another way to put it....a monthly 'battery bill' of $25 to $120 depending on battery bank size, and how many years they pamper it to last....or torture it to premature death. The GTBB backlash from the utilities is just more smoke and mirrors.....I'll try to get something up on HuffPost before I leave for Canada next week.....

Its even higher for sealed batteries and Li+. It would have to be an amazing cost difference in the TOU rates to beat the battery cost plus all the losses of AC charging/ discharging a battery. I agree with Phil, as I've seen utilities obstruct solar since the 1980s. Unfortunately their attitude has still not changed. Its pretty dumb too; battery storage could help improve the reliability of the grid. You can't retire yet folks, we have another battle to fight.

Yes, perhaps you can make a buck or two if the delta is big enough. However, that's like driving forty miles in your 4x4 to use a dollar coupon instead of shopping at the grocery store down the block. There are just better ways to make a buck. At the end of the day, what should matter in NEM is what generated the energy that is exported. The customer should be able to maintain their battery by charging from grid, solar, or any combination. The batteries are not a balloon -- energy used to charge them doesn't come rushing back out. Batteries are like a bucket -- if the inverter can only sell what flows over the top, then it takes solar input to begin flowing. Ultimately, it's going to take a chorus of voices to get the CPUC to tell the utilities to shape up and stop obstructing these systems. If people stay silent, the utilities get their way. It's your industry, it's your business. It's your choice.
