The California Feed-In Tariff
Well to be honest, it hit me hard. The head of the Energy Division at the California Public Utilities Commission was taking a shot at me. At issue is how to fund solar systems and how to make solar investments a good deal. Sean Gallagher took exception with my assertion that California is applying the brakes with limits on net metering. He claimed that there has to be balance in the level of subsidy. And didn't I know that California has a feed-in tariff? No, frankly, I did not. In EcoMotion Network News Volume 11#10 I challenged the State to follow the German feed-in tariff model that is working so well.
Gallagher asserts that net energy metering has not one but two benefits. In addition to paying small producers retail rates for on-site generation, participants enjoy the benefits of being connected to the grid. "…With solar net metering, they get credit against the transmission and distribution components of their bill when they produce energy, not just the energy commodity component of the bill. Of course, the customer still receives transmission and distribution service from the utility in the hours when the premise is a net consumer of energy. So solar net metering down to zero is a pretty good deal for customers. It is really a second subsidy, in addition to the rebate program." While Gallagher is a strong solar advocate, particularly mandating solar in new developments in appropriate climate zones, he noted, "…other ratepayers, not the utility, effectively pay for net metering. So if you increase the net metering subsidy by allowing the bill to go negative, other ratepayers must pay for it." This is the crux of the policy issue: What level of incentives will move the solar market, and what level of rate increase will our society accept to support sustainable energy resources? In Germany, consumer willingness to pay for renewables was analyzed, and consumers there are willing to pay. The feed-in tariff model allows any solar producer to maximize production without limits.
Sean Gallagher then reported on his division's work developing a feed-in tariff in California: "Happily, perhaps, there is also a feed-in tariff solution. The Commission's implementation of AB 1969 from 2006 expanded on the requirements of the bill to allow any customer to install a small renewable facility (up to 1.5 MW) and sell ALL the energy to the local utility, at the MPR rate. Of course, a customer can't get both net metering and the feed in tariff approach, but now customers can choose based on which approach is a better fit for them." I thanked Sean and dug in to CPUC Draft Resolution E-4137.
The California Feed-In Tariff - formally presented in a CPUC Draft Resolution E-4137 on "tariffs for the purchase of eligible renewable energy generation" - will come before the CPUC Commissioners for approval at their upcoming December 20th meeting. The tariff's genesis was AB 1969 which passed in September 2006. It was designed to accommodate water and wastewater facilities that sought to feed power back into the grid. The CPUC was charged with developing a suitable tariff, and ultimately a resolution called for 250 MW of renewables from water and wastewater facilities statewide. SCE and PG&E expanded the offering to 228 MW for other, "non-water and wastewater facilities."
Further, the feed-in tariff is based on MPR, the so-called "market price referent" and pays renewable energy providers with 10, 15, and 20-year contracts for fixed "feed-in" prices of 9.2 - 11.954 cents per kWh, plus a "time of delivery" (TOD) factor, basically a relatively small sum. (The MPR is the "predicted annual average cost for a base-load proxy plant.") While the tariff may be a good start, it's far from the German model that pays over fifty cents a kilowatt-hour! It certainly appears far from playing a major role in progressing renewable energy and solar power in California; at its current rates it will not become a common means for the average citizen or business or government facility to go solar.
Molly Sturkel at the CPUC writes that, "We're not sure what the interest level will be... but plan to watch it closely. For [power users] that have average retail electric rates below the MPR (like some that actively manage their load to get close to whole power rates) -- this is a good tariff opportunity."
