Powin’s Latest Deal Hints at Maturation for Energy Storage Project Financing
Powin Energy, the Oregon-based energy storage developer, is expecting to see an uptick in non-recourse financing following a landmark project this month.
The company secured construction financing for an 8.8-megawatt/40.8-megawatt-hour battery plant in Stratford, Ontario, from Brookfield Renewable Partners, one of the largest independent renewable energy businesses in the world.
“Securing non-recourse financing is a critical step for energy storage assets themselves, as well as the broader market,” said Geoffrey Brown, Powin Energy president, in a press release. “We believe that closing a deal of this nature with a well-respected group like Brookfield is indicative of market maturation and Powin’s future prospects.”
While the non-recourse funding model is commonplace in most renewable energy markets, the track record is more limited in energy storage. Only a handful of deals have made headlines.
Last year, for example, another Ontario project based on flywheels and lithium-ion batteries and built by Convergent Energy and Power was funded through a non-recourse finance package from CJF Capital and SUSI Partners’ Energy Storage Fund I.
“The facility reflects a non-recourse, third-party project financing structure for energy storage assets in a sector dominated by on-balance-sheet financing,” noted Convergent in a press statement.
And in 2015, half the money for the Jake and Elwood battery storage projects developed by Renewable Energy Systems Americas came from non-recourse senior secured project financing debt.
Brown said he thought many energy storage projects since had been difficult to fund through non-recourse debt because of the nature of their contracts.
Following the Stratford deal, though, Brown told GTM he expected non-recourse funding to become the norm for energy storage projects with clear, fixed revenue streams.
“If you’re talking about contracted or not just purely ancillary services revenue, then the percentage of projects that are going to have some level of non-recourse debt financing is substantial,” he said. “Energy storage is the type of thing that, if you’re talking non-recourse debt financing, naturally is attractive to capital.”
Investor understanding of the technical side of battery storage has increased in recent years, said Brown. “Now it’s just about driving up the volume of projects. We don’t expect storage to be different to any other renewable energy.”
Non-recourse finance, loans where the lender is only entitled to repayment from the benefits of a project and not from the other assets of the borrower, has been growing in importance in other green energy sectors.
The model is particularly suited to capital-intensive projects that deliver regular income over long periods, as is typically the case with wind or solar plants.
In 2014, it accounted for 32 percent of the money going to all new renewable energy assets, according to Bloomberg New Energy Finance’s 2015 Global Trends in Renewable Energy Investment report.
