Description The developer of what would be the region’s biggest energy storage project is asking federal regulators for more time to begin construction. But executives at Rye Development, which is managing the Swan Lake North pumped-storage hydropower project for owner Copenhagen Infrastructure Partners, said the two-year extension to April 2025 doesn’t indicate trouble for the $1 billion project. “We feel as confident as ever,” Michael Rooney, Rye’s vice president of project management, said. Rooney and colleague Erik Steimle, vice president of project development at Rye, said they expect federal energy regulators to issue a notice to proceed with construction by the end of the year, and for work to begin in early 2024. The Klamath County project is expected to take four years to build. They were mum on where they stand as far as landing an offtaker for the project’s power, a prerequisite to beginning construction, but it didn’t sound like an insurmountable obstacle. “I can just share that we’ve got really solid interest in the project across Oregon, Washington and California,” Rooney said. Portland General Electric included Swan Lake North on its final short list of projects in an ongoing renewables solicitation, but beyond a Montana wind farm, the utility hasn’t publicly settled on what resources it plans to acquire. Neither PGE nor Rye would comment on whether Swan Lake North was in play for the utility. The big price tag, long construction horizon and the fact that significant pumped storage hasn’t been built in the U.S. in decades have been complicating factors in pitching the project, which was licensed by the Federal Energy Regulatory Commission in 2019. But Rye thinks the timing for the project couldn’t be better now, with California, Washington and Oregon all pursuing aggressive 100% clean electricity goals. That means a lot more renewable energy will soon be flowing onto the grid, and not always when it’s most needed. Swan Lake North would act as a giant rechargeable battery by pumping water from a lower reservoir to an upper reservoir when energy is plentiful, then releasing it down through electricity-generating turbines in a closed-loop system when demand rises. Swan Lake North would be able to generate around 400 megawatts of power — just a shade under what PGE’s natural-gas-fired Carty Generating Station puts out — for at least eight hours. It would dwarf the largest existing grid-connected energy storage system in Oregon, a new PGE facility that uses lithium-ion batteries that can generate 30 megawatts for four hours. Also working in the project’s favor: The Inflation Reduction Act made it eligible for a 30% investment tax credit. That could rise to 40% if the project meets domestic content requirements, and might even climb to 50% based on other criteria still being fine-tuned by the feds. _________________________________________________________ As of October 6, 2022, the project is in final planning. No applications or building permits have been submitted into the City of Pine Grove. Information regarding the architect and general contractor has not been disclosed. A firm construction timeline has not been set, however, construction is not expected to begin prior to early 2023.
