It’s a question we hear all the time: Why doesn’t California have a German-style feed-in tariff for the solar industry? German utilities pay a high price for any solar electricity fed into the grid, with the cost distributed among the country’s ratepayers. The much-esteemed policy made Germany a huge solar market, with 1.5 gigawatts of new capacity installed last year. For comparison, the United States would need 6 gigawatts of annual solar installations, 20 times more than it has today, to reach the same level of market penetration.
But at a luncheon Wednesday to discuss solar trends in advance of the Intersolar North America conference next month, some California solar insiders voiced skepticism about whether a German-style feed-in tariff would be the end-all policy for the state.
In fact, California already has a feed-in tariff, but it’s ineffective because the price is low, based on prices for natural gas. The state also has a net-metering program in which solar customers use the electricity they generate for their own use, then feed excess electricity into the grid, running their meters backward. In addition, California has a solar incentive program, which offers declining rebates for solar projects, and a renewable portfolio standard, which requires utilities to get 20 percent of their electricity from renewable sources by 2010.
