Warren Buffett's MidAmerican Energy Holdings Co. said on Wednesday it would make its first move into solar energy with the purchase of First Solar Topaz Solar Farm power plant in California, one of the two largest under construction in the world.
MidAmerican Energy, the utility arm of Berkshire Hathaway Inc., already operates wind power facilities, and its move into solar comes amid growing worries about the solar industry's ability to finance large utility-scale projects.
Financial details of the transaction were not available. Shares of First Solar rose as much as 12.5 per cent on the Nasdaq Stock Market on Wednesday.
The deal for the plant, which at 550 megawatts would equal the capacity of First Solar's Desert Sunlight plant, comes after First Solar failed to win a U.S. loan guarantee to help finance its construction.
The Topaz plant, being built in San Luis Obispo County, will have the capacity to generate enough energy to power about 160,000 average California homes, MidAmerican Energy said in a statement.
The deal "demonstrates that solar energy is a commercially viable technology without the support of governmental loan guarantees," Greg Abel, president and chief executive officer of MidAmerican, said in a statement.
Analysts speculated that the plant's sale price was likely inside the range that First Solar had sold previous projects on a per-watt basis, putting it between $1.65-billion (U.S.) and $1.95-billion.
"If nothing else, what this does is it tells you that First Solar will be able to sell what it makes, and that certainly is better than any other solar company can say at this point," said Jeff Bencik, an analyst at Kaufman Bros.
The acquisition dovetails with Berkshire's increasing interest in solar technologies in recent years, the most notable example being its investment in China's BYD Co. Ltd.
Though BYD is best known for its electric cars, it is also one of the world's largest battery makers and has a nascent solar panel business as well.
Even though financial details were not disclosed, First Solar's struggles financing the plant suggest that Berkshire likely got a good deal, which fits in with Mr. Buffett's value investing strategy.
He famously said earlier this year he had a loaded elephant gun with which he was searching for big deals, and he has made a number of them, including the $9-billion takeover of chemical maker Lubrizol Corp. and an $11-billion investment in IBM Corp.
Ever since Mr. Buffett took a nearly 10-per-cent stake in BYD during the depths of the financial crisis in late 2008 – through MidAmerican rather than Berkshire proper – Buffett watchers have speculated the company had an interest in using BYD's battery technology at renewable energy plants.
Mr. Buffett's long-time business partner Charlie Munger has also been a cheerleader for the potential of solar.
"All kinds of things are going to be possible once we really gear up to harness the sun," Mr. Munger once said in a CNNMoney interview. "That has always required cheaper solar and better batteries and they're both coming."
The Topaz plant may qualify for a cash grant totalling 30 per cent of its construction costs under a program that expires at the end of 2011. That cash grant program will turn into a tax incentive at the beginning of next year.
Pacific Gas and Electric Co. will buy the electricity from Topaz under a 25-year agreement, Des Moines, Iowa-based MidAmerican Energy said.
First Solar had hoped to secure a loan guarantee from the U.S. government to help finance construction of the plant as it had for other large solar projects.
But political pressure on the U.S. Department of Energy following the collapse of start-up solar manufacturer Solyndra LLC prompted new scrutiny on the loan guarantee application process, and First Energy was not able to meet the end-of-September program deadline.
Solyndra, which had received more than $500-million of government funding, collapsed into bankruptcy at the beginning of September.
First Solar is the largest U.S. photovoltaic solar company and the world's lowest-cost solar manufacturer.
But along with others in the sector, it has been hit hard by a glut of solar panels on the market that has driven prices down by 40 per cent so far this year, narrowing its cost advantage over its rivals in China and Europe.
