Yep, this is interesting. Consumption goes down, so rates have to go up. See what you get for conserving energy. The cost of fuel is only around 3.5 c/kWh so ratepayers get slight temporary relief from declining fuel prices. Beyond that you have a butt load of fixed assets to maintain. Thus, if ratepayers consume less, rates must increase to cover all the fixed cost.
Now in that context, you can see why rooftop solar is so problematic. It simply reduces consumption. The utility would like to add a special interconnection fee for customers who self-generate. The reason is simple, they've got fixed costs to cover.
So should we cheer them for investing in solar? No, it just adds more fixed cost. Even if fuel consumption and prices drop more as a result of utility solar, it is all those fixed costs that drive up the power bill.
When utility move to a service model instead of a fixed asset rental model, then ratepayers will benefit from truly variable cost pricing. For example, netting 1.2c/kWh for redistributing residential solar power does not add any fixed costs to the system and allows the utility to prune its fixed cost over time. So it can become a lighter weight system over time. But adding utility solar or any other generation facility adds fixed costs that remaining ratepayers will bear for the next 30 years.
Also note that the rate hIke is 15.8% for residential customers, but 14.4% for all ratepayers. Thus, the residential sector is bearing more of the weight of this system than the industrial and possibly commercial sectors. I strongly suspect that there is cost shifting from industry to families.
On the positive side, this rate increase should help SolarCity with their marketing efforts. Even an escalator on a PPA does not look so bad when the utility has demonstrated it will raise rates on whoever is left on the grid.
What happens when residential ratepayers learn that they cannot lower their power bill simply by reducing consumption? The more you conserve, the more you pay.
What about the argument that you publish commercial rates based upon demand and then pay the market at those prices.
Homeowners become power producers through their aggregator. In this case, it's Solar City.
Or John Smith can build his own solar "field" and become a micro entrepreneur.
Seems to be working in Germany.
Haven't heard a good counter argument other than "utility death spiral".
