PG&E ramps up solar financing with $100 million fund

In The New York Times on Monday, I write about a $100 million tax equity fund created by PG&E Corporation to finance residential solar installations:

P.G.&E. Corporation, the California utility holding company, has created a $100 million tax-equity fund to finance residential solar installations by SunRun, a San Francisco start-up that leases photovoltaic arrays to homeowners.

The fund, managed by a P.G.&E. subsidiary, Pacific Energy Capital II, is the largest single solar leasing pool to date, according to the company, and marks the growing interest of utilities in the renewable energy financing business.

“We’re in somewhat of a unique position in that roughly half of the nation’s rooftop solar installations are in our service territory,” Brian Steel, P.G.&E.’s senior director of corporate strategy, said in an interview. “We’re at the proverbial ground zero of these new technologies and so perhaps more than any utility holding company in the country we have a strategic imperative to get ahead of the curve through having a propriety seat at the table with a partner like SunRun.”

The financing, announced Monday, follows P.G.&E.’s creation of a $60 million tax-equity vehicle in January for SolarCity, a Silicon Valley company that also leases solar arrays to homeowners.

The $100 million in financing is expected to fund solar installations for 3,500 homes in Arizona, California, Colorado, Massachusetts and New Jersey.

“That a major energy company like P.G.&E. is coming to the table illustrates that distributed solar is becoming part of the mainstream energy business,” said Edward Fenster, SunRun’s chief executive.

Solar revolution prompts rethink of grid projects

In my Green State column in Grist this week, I talk to Ryan Pletka, a renewable energy expert at engineering and consulting firm Black & Veatch, who has been conducting economic analysis for California’s Renewable Energy Transmission Initiative.  The rapid evolution of the solar market has prompted Pletka to rethink the the need for massive new transmission projects in California:

California’s ambitious goal of obtaining a third of its electricity from renewable sources by 2020 has spawned a green energy boom with thousands of megawatts of solar, wind, and biomass power plants planned for … the middle of nowhere.

And therein lies the elephant in the green room: transmission. Connecting solar farms and geothermal plants in the Mojave Desert and wind farms in the Tehachapis to coastal metropolises means building a massive new transmission system. The cost for 13 major new power lines would top $15.7 billion, according to a report released in August by the state’s Renewable Energy Transmission Initiative.

The initiative, called RETI, is an attempt to build a statewide green grid in an environmentally sensitive way that will avoid the years-long legal battles that have short-circuited past transmission projects.

But the rapidly evolving solar photovoltaic market may moot the need for some of those expensive and contentious transmission lines, requiring transmission planners to rethink their long-term plans, according to Black & Veatch, the giant consulting and engineering firm that does economic analysis for RETI.

In short, solar panel prices have plummeted so much as to make viable the prospect of generating gigawatts of electricity from rooftops and photovoltaic farms built near cities.

“This has pretty significant implications in terms of transmission planning,” Ryan Pletka, Black & Veatch’s renewable energy project manager, told me last week. “What we thought would happen in a five-year time frame has happened in one year.”
