California utilities lead in solar energy, report says
West Coast utilities are charging ahead with solar plants, but other regions could surpass them soon, according to the Solar Electric Power Association.
Southern California Edison is leading the way as utilities become the solar industry's largest customers, according to a report Wednesday by the Solar Electric Power Association, whose members include solar tech companies and more than 300 utilities.
The utility is ahead of its counterparts in both overall solar energy capacity per megawatt and per customer, the study found (PDF). Further north, Pacific Gas & Electric is in front in terms of overall solar capacity and megawatts per customer.
The nonprofit solar association compiled the rankings from data collected from 50 utilities this spring. It projected growth in U.S. solar electricity, particularly photovoltaics, to expand to 600 megawatts in 2012 from 150 megawatts last year.
Southern California Edison came out on top largely due to its interest in large, concentrating solar thermal projects, such as a. And it's working to build panels across 65 million square feet of rooftops.
However,under way by other electricity providers could dethrone the Southern California utility from its top spot, the report predicted.
Golden State utilities may be the earliest solar adopters, but others in the West, Midwest and Mid-Atlantic regions are also increasingly embracing renewables, according to the study.
In its forecast, 4,600 megawatts of concentrating solar systems will be planned nationwide within the next eight years, at least 600 megawatts of which won't come from sprawling solar farms.
For instance, initiatives to encourage solar adoption by homeowners and businesses are coming from Duke Energy, Long Island Power Authority, San Diego Gas & Electric, and Southern California Edison.
State renewable energy portfolio standards will help to advance adoption of big solar installations, but progress will stall if, which are set to expire at the end of the year, aren't extended, said the report's author, Mike Taylor, in a conference call.
"We're hitting some new momentum with new business models, but this tax credit uncertainty is potentially holding things back and creating some friction in the system," added Taylor, the association's research director. "A lot of utilities are waiting in the wings to see what's happening. Some are jumping ahead of the game because they want to be the first movers."
By his group's estimation, other states making inroads with solar power include Arizona, Colorado, Hawaii, Illinois, Nevada, New Jersey, New York, Texas, Washington, and Wisconsin.
