Minnesota soon could see at least a sevenfold expansion of solar power.
In
an unprecedented ruling, a judge reviewing whether Xcel Energy should
invest in new natural gas generators vs. large solar power arrays
concluded Tuesday that solar is a better deal.

If
the finding by Administrative Law Judge Eric Lipman is upheld by the
state Public Utilities Commission (PUC), Edina-based Geronimo Energy
plans to build about 20 large solar power arrays on sites across Xcel’s
service area at a cost of $250 million.

“It says
solar is coming in a big way to the country and to Minnesota,” Geronimo
Vice President Betsy Engelking said of the ruling.

Geronimo’s
Aurora Solar Project would receive no state or utility subsidies, but
would qualify for a federal investment tax credit. Engleking said it is
the first time in the United States that solar energy without a state
subsidy has beaten natural gas in an official, head-to-head price
comparison.

“The cost of solar has come down
much faster than anyone had anticipated,” she said in an interview.

The
largest of the Geronimo projects would be five times bigger than the
state’s largest solar array in Slayton, Minn. Some would cover up to 70
acres of land. The proposed sites are in 17 counties, mostly in central,
eastern and southeastern Minnesota.

It is the
first time the state has used a competitive bidding process for a major
power generation project. The commission ordered the trial-like
proceeding to force energy companies to compete on price.

Xcel,
based in Minneapolis, and three other energy companies offered various
proposals, mostly generators powered by natural gas. Xcel’s plan
included a new gas generator at its Black Dog plant in Burnsville, where
the utility intends to retire the remaining coal-burning units.

In
a 50-page ruling, Lipman said “the greatest value to Minnesota and
Xcel’s ratepayers is drawn from selecting Geronimo’s solar energy
proposal …”

If the Aurora project is built, Xcel
likely would purchase the power under a long-term agreement. That could
help Xcel toward its requirement to get 1.5 percent of its power from
the sun by 2020 under a new state energy law. Xcel also is counting on
rooftop solar systems, community-owned arrays and its own large projects
to meet that goal.

Lipman said that if solar
alone can’t supply all of Xcel’s extra power needs in the next few
years, the utility could take up an offer to purchase surplus energy
from Great River Energy, the state’s second-largest power company. The
judge also said Xcel will have time to consider other generation
projects if electrical demand picks up.

Xcel
said in a statement that it appreciated Lipman’s work, but that it
disagreed with some of the findings and would file a written response.
Under the PUC’s rules, the competitors and other interests can take
exception to the judge’s ruling before the five-member commission takes a
vote.

Geronimo already does business with Xcel,
selling the output of its Prairie Rose Wind Farm in Rock County, in far
southwestern Minnesota. Two of four planned wind farms that Xcel will
add in the next two years — near Windom, Minn., and near Jamestown, N.D.
— are being built by Geronimo. The company has built two smaller wind
farms in southeastern Minnesota and is about to construct two more wind
farms in Michigan and Nebraska for other utilities.

Other competitors
The
other competitors considered by the judge were Houston-based Calpine,
which proposed a gas turbine in Mankato at its existing power plant
there and Chicago-based Invenergy, which proposed gas turbines at Cannon
Falls and Hampton. Xcel also proposed two gas units near Hankinson,
N.D.

“We are reviewing the [judge’s]
recommendations, and will evaluate our next steps in the docketed
proceeding,” Craig Gordon, Invenergy vice president of sales and
marketing, said in an e-mail Tuesday.

If the
Aurora Project is approved, Geronimo said the solar arrays would be
built in 2015 and 2016. Engelking said that Geronimo already has signed
deals for land and that it has identified more sites than needed in case
some don’t work out.

Each of the ground-mounted arrays would be next to an existing substation, avoiding transmission-line costs.
She
said the company still needs state or local permits. But the company
has visited with local governments and has pledged to make payments in
lieu of taxes ranging from $50,000 to $110,000 a year.

Geronimo,
a renewable energy developer, doesn’t intend to own the projects, she
said. Its financing partner, Enel Green Power, has the first option to
acquire them, she said. But it’s possible Geronimo could make a deal to
sell the arrays to Xcel or other energy companies, she said.
