Israeli solar power plant developer Solel announced Monday it has scored $105 million in funding from London-based investment firm Ecofin — yet another sign that the market for large-scale solar energy projects is reaching critical mass.
Solel last July signed the world’s largest solar power deal when it agreed to supply California utility PG&E (PCG) with 553 megawatts of green electricity to be produced by a massive solar thermal power plant to be built in the Mojave Desert. The company’s solar trough technology is also used in nine solar power plants (photo above) that were built in the Southern California desert in the 1980s. (In a solar trough power plant, long rows of parabolic mirrors focus the sun’s rays on tubes of liquid suspended over the arrays to create steam that drives an electricity-generating turbine.)
Raising $105 million is impressive and it’s certainly a big number. But given that a 500-megawatt solar power plant can easily cost $1 billion or more to build, it’s a relative drop in the bucket. However, it will allow Solel to move forward with the project and line up project financing for the PG&E plant while it negotiates more deals with other utilities — it won’t say which, but likely candidates are Southern California Edison (EIX) and San Diego Gas & Electric (SRE).
Competitors BrightSource Energy and Ausra have solar power plant applications before the California Energy Commission and have signed or are negotiating power purchase agreements with PG&E.
“Everyone is realizing that the market is there for thousands of megawatts of peaking power,” Solel CEO Avi Brenmiller recently told Green Wombat. “As time goes by we see energy prices rising and utilities are focusing their efforts to get solar thermal power because this is the right solution in the southwest United States.”
The Ecofin investment in Solel is notable also given the uncertainty surrounding solar power at the moment due to Congress’ failure to extend the solar investment tax credit in the recently enacted energy bill. The 30 percent credit is considered crucial to help solar energy companies secure financing for power plants and achieve economies of scale. The tax credit expires at the end of 2008 but solar energy proponents and their allies on Wall Street say they’re confident that Congress will take up legislation this session to extend it for as long as eight years.

WASHINGTON (Dow Jones)–Senate Finance Committee Chairman Max Baucus, D-Mont., has agreed to extend expiring tax credits for wind, biomass and other renewable energy sources in a $160 billion economic stimulus plan being debated by his committee Wednesday afternoon.
The addition won praise from committee Democrats and Sen. Charles Grassley of Iowa, the highest-ranking Republican on the committee.
The provision would extend the production credit for electricity produced from wind, closed-loop biomass, open-loop biomass, and other sources by one year, through Dec. 31, 2009.
Such changes are being opposed by Senate GOP leaders, who argue that they diverge from an agreement reached between the Bush administration and House leaders and could put the chances for passing an economic stimulus bill at risk.
The Senate Finance Committee is expected to approve Baucus’s version of the plan. But given GOP leaders’ opposition, its fate on the Senate floor remains unclear.
