It's often the hand of regulators and legislators that guides the direction of regulated utilities, rather than the hand of the free market. And when it comes to renewable-energy-friendly legislation, the summer and fall of 2013 were mostly unicorns and rainbows for the fate ofsolarpower and energy storage in California. Here's the rundown.
AB 327: Net metering and rate reform. AB 327 is now California state law and it ensures that net metering (which pays solar-equipped customers retail prices for the solar power delivered to the grid) will stay in place until at least 2016. The law also gives the California Public Utilities Commission authority to completely remove caps on the program, rather than sticking to the 5 percent of nameplate generation capacity quota that was previously in place.
The law carries with it a signing statement from Governor Jerry Brown. As reported by Jeff St. John, Brown noted, "As the CPUC considers rules regarding grandfathering of net metering customers, I expect the Commission to ensure that customers who took service under net metering prior to reaching the statutory net metering cap on or before July 1, 2017, are protected under those rules for the expected life of their systems."
The value of solar power and the threat that net energy metering poses to the utility business model will be demonstrated, one way or another, in the California laboratory in the coming years.
SB 43: Shared solar, community solar, solar gardens, and virtual net metering. This type of solar financing has name-recognition and brandings problem, but basically it allows renters or people with shaded roofs to go solar. Signed into law earlier this month, the law launches a new 600-megawatt program that lets customers of IOUs purchase up to 100% of their electrical power from a remote solar power plant. The maximum project size is 20 megawatts, and 100 megawatts are being set aside for "the most impacted and disadvantaged communities" and "[a]reas disproportionately affected by environmental pollution." (Here's the full text of the Green Tariff Shared Renewables Program.)
AB 217: Expansion and continuation of low-income solar program. Slated to end in 2016 but now extended to 2021 are the Single-Family Affordable Solar Homes and Multi-Family Affordable Solar Housing (SASH and MASH) programs, worth a combined $108 million. The programs offer rebates and provide training in solar installation. According to the text of the law, "It is the goal of the state to install solar energy systems that have a generating capacity equivalent to 50 megawatts for low-income residential housing."
Last month, the California PUC set terms of a mandate for an eye-popping 1.3 gigawatts of energy storage to support the state’s power grid by 2020. As reported by Jeff St. John, the decision "breaks new ground in seeking to establish a regulatory regime in which utilities, third-party storage providers, and even customer-owned storage assets can play an integrated role. Those include rules that would limit utilities from owning more than 50 percent of the total amount of energy storage to be procured across the three “grid domains” of transmission, distribution, and customer-located storage.
That decision comes in spite of requests from the state’s three investor-owned utilities -- Southern California Edison, San Diego Gas & Electric and Pacific Gas & Electric -- that they be able to control a larger share of the storage they would be required to connect to their grids.
“This is pretty significant, because they’re saying that utilities can even own assets behind the meter,” Janice Lin, executive director of the California Energy Storage Alliance (CESA), an industry group representing energy storage companies, said in an interview.
As with NEM, the California renewable experiment with mandated energy storage is going to be watched very carefully by other states.
