In Wisconsin, where state regulators and utilities have been perceived as cool to renewable energy, rural cooperatives are making major investments in solar power.
According to solar installers and experts, co-ops, which aren’t subject to regulation by the state’s Public Service Commission, are being more responsive to their customers’ interest in solar.
“What’s very important here is working with cooperatives, they have more flexibility,” said SoCore senior vice president of sales Rob Scheuermann.
Dairyland is a generation & transmission (or G&T) cooperative, that brings together 25 smaller member electric cooperatives and 17 municipal utilities in Wisconsin, Iowa, Minnesota and Illinois. Such G&T cooperatives provide wholesale power to distribution cooperatives, which deliver the electricity to customers in rural areas.
Currently Dairyland has only 3 MW of small solar and bio-digesters in its system. The cooperative had incentive to increase its renewable resources because of the closing of DTE Energy’s 40 MW Stoneman biomass plant in Cassville, Wisconsin. Dairyland’s contract with that plant had helped meet its state renewable portfolio obligations.
“Dairyland Power is committed to expanding our investment in solar and other renewables for two main reasons: our members have expressed interest and we continue to diversify our generation portfolio with more renewable energy as part of Dairyland’s overall strategic plan,” said manager of business development Craig Harmes. “It is good business practice.”
Dairyland has entered Power Purchase Agreements with two solar developers that will build and own solar installations providing energy to customers in member cooperatives. The cooperative got 30 answers offering 100 different plans in response to its request for proposals last summer, according to Harmes.
SoCore senior vice president of development Eric Luesebrink said the project “is really kind of an innovative program” in its design and structure.
“Setting aside the fact it’s probably the largest single solar contracting exercise in Wisconsin, I don’t of know any other approach that’s been collaborative with distribution cooperatives and generation and transmission cooperatives like this,” he said.
Scheuermann said Dairyland’s RFP didn’t specify that projects had to be scattered over multiple sites, but “I think at the end of the day Dairyland liked the distributed nature of the projects and it fit in well with the grid.”
Distributed projects are “typically better absorbed by the power grid without significant impact on the local infrastructure and reliability,” confirmed Harmes. Since the sites are all located near existing utility substations, significant upgrades to the grid should not be needed. SoCore is leasing sites from farmers or landowners with unused space.
“We really worked with the transmission members of Dairyland – who were really asking for solar,” said Scheuermann. “By partnering with them we really gained a lot of support within the network to do this project, as well as landowners who were really excited about it, as well as member co-ops, who are thinking about their own community solar garden projects, whether we can build systems for them outside of this.”
From one farming state to another
GroSolar’s installation will involve 6- to 8-foot-tall tracking panels that move with the sun, increasing efficiency 15 percent over stationary panels. The company says it will provide about 5,000 MWh in the first year, enough to power about 470 homes.
GroSolar spokesperson Maribeth Sawchuk said the company has no other developments in Wisconsin, and is “hoping to use this to get more contacts in the state, and see how local folks feel about solar.”
Sawchuck said the company often does installations on city property, old landfills and universities. GroSolar’s 2.5 MW, 10-acre installation on the Rutland city landfill in Vermont is part of Green Mountain Power’s heavy investment in renewable energy.
The company says the Wisconsin construction will mean about $750,000 in direct wages and more than $1.5 million economic impact on the area, with local contractors hired.
“It’s not just about installing solar, it’s about helping the environment, creating jobs and so much more,” she said.
A cooperative model
Keith Reopelle, senior policy director of Clean Wisconsin, said the group is “very pleased” with the Dairyland investment in solar especially given the challenges that solar faces in utility service territories.
“It is interesting we’ve seen more activity and investment by co-ops and municipal utilities under a little bit of a different model,” he said. “It makes sense because they are really just trying to be as responsive as they can to their members. Whether served by investor-owned utilities or cooperatives, solar is becoming more and more popular as the price goes down; and co-ops maybe have an advantage as they are able to be more nimble and more responsive to their customer base.”
“It’s really impressive to see all over the country how cooperatives are embracing solar and finding new ways to implement it,” added Andy Olsen, with the Environmental Law & Policy Center. “There are a number of things that led them to this, to diversify their generation mix and move away from fossil fuels, which they have to do regardless of what happens with the Clean Power Plan.”
Scheuermann said SoCore has received an enthusiastic reception from local landowners and neighbors, and he hopes the project can help drive the solar market in Wisconsin more broadly, including encouraging Wisconsin utilities to welcome solar.
“It’s just unfortunate that for a state where there’s only 25 MW of solar developed, that very early on it got a little contentious between the solar developers and the Public Service Commission,” he said.
In other states, he added, SoCore “has some opportunities where we’re working to bring customers who want solar to the utility, and we could be developing solar on behalf of the utility, selling it to the utility so the utility can serve customers the way they want to be served. It’s not always a contentious situation – a lot of times utilities do embrace solar.”
