Solar panels on high-value farmland raise concerns
Solar power technology draws no objections from farmer Sam Sweeney.
In fact, he’s got 600 square feet of solar panels on his property near Dayton, Ore.
“It’s time to explore other options for energy,” Sweeney said.
However, the potential for solar development on prime farmland in Oregon’s Willamette Valley does make Sweeney anxious.
Three solar companies have sent letters offering to lease his property at rates several times higher than other growers would typically pay.
While Sweeney has ignored the offers, he realizes other growers will be tempted by such deals.
“When I saw that, I thought, ‘Gosh, these are probably going out all over the valley,’” he said. “A lot of people are going to think this is really an opportunity. Before we know it, we could have a lot of these scattered about on really high quality soil.”
Those concerns are shared by the Oregon Board of Agriculture and the Oregon Department of Agriculture, which plan to formally ask the state’s Land Conservation and Development Commission to re-examine regulations for solar development on high-value farmland.
Currently, the rules allow solar facilities to be constructed on up to 12 acres of high-value farmland as long as the local county government issues a conditional use permit.
Larger projects must undergo an analysis of alternative sites, but there’s a concern that developers might circumvent that requirement with several smaller projects.
“Cumulatively, they may have the same impact as a large one,” said Jim Johnson, ODA’s land use specialist. “They’re doing large-scale operations by breaking them up and having components.”
Originally, the 12-acre threshold was established so farmers could supplement their income, but now that solar companies are looking to develop several properties, it’s time to re-evaluate the rule, he said.
One possibility would be to reduce the threshold to 5 acres, and subject larger projects to an alternative site analysis, Johnson said.
Solar development is more intensive than simply installing some panels — developers generally move soil, add gravel and build fences, said Larry Ojua, executive director of the Yamhill Soil and Water Conservation District, which has raised concerns over two recent solar projects in Yamhill County, southwest of Portland.
Once a lease for a solar project expires, the changes raise doubts about returning the farmland to its previous condition, he said. “What if the company goes out of business?”
Unlike wind energy, which is largely compatible with agriculture, solar development entails a greater risk of permanent land conversion, said Barbara Boyer, chair of the Oregon Soil and Water Conservation Commission and vice chair of the Oregon Board of Agriculture.
“You can’t farm underneath them, like you can with the wind turbines,” she said.
Solar companies develop projects in Western Oregon even though the region’s “solar resource” is about 30-40 percent lower than in Central or Eastern Oregon, said Rob Del Mar, policy analyst for the Oregon Department of Energy.
“The solar resource is not stellar, not ideal, but it’s adequate,” he said.
Nonetheless, building solar facilities on the westside is efficient because that’s where most of the population — and energy consumption — are, Del Mar said.
Costs for solar hardware and installation have also declined in recent years, he said. “It’s so much cheaper than it used to be, and the market has really matured.”
Oregon’s “business energy tax credit” expired in 2014, but a federal tax credit for 30 percent of project costs is still available.
The state Department of Energy also dispenses grants for renewable energy projects, with 13 projects receiving a total of $1.5 million from the agency this year. Energy Trust of Oregon, a nonprofit, also provides cash incentives for renewable energy development.
Jeff Bissonnette, executive director of the Oregon Solar Energy Industries Association, said he’s aware of concerns about solar development on prime farmland but hadn’t heard about the push for rule changes.
Bissonnette said he’d have to see specific policy proposals before commenting on them.
“That’s always a conversation we’re willing to engage in,” he said.
Prices for electricity aren’t currently high enough to justify a “gold rush” of solar development in Western Oregon, said Alan Hickenbottom, a principal at Latitude45 Associates, which consults on solar projects.
Developing several small projects, rather than one big one, is less efficient because it would require multiple “interconnections” hooking them up to the electrical grid, he said.
“I’m wondering how it would pencil for them,” said Hickenbottom.
