Clean Energy Funds

The Clean Energy Fund enables a mix of projects administered by Commerce's State Energy Office. Funding will support development, demonstration, and deployment of clean energy technologies that save energy and reduce energy costs, reduce harmful air emissions, or otherwise increase energy independence for the state. 

Clean Energy Revolving Loan Fund Grants

These grants finance use of proven building energy efficiency and renewable energy technologies that currently lack access to capital. The program generates opportunities within the residential and commercial sectors. 
Craft3 is a nonprofit CDFI lender serving the rural and urban low-income communities of Oregon and
Washington. Craft3 is administering two clean energy loan programs: a commercial and a residential lending program.

Puget Sound Cooperative Credit Union
Puget Sound Cooperative Credit Union has offered financial services to the Puget Sound region since 1934. They are a not-for-profit banking alternative, owned by their members. PSCCU is administering a residential clean energy lending program.

Smart Grid Grants to Utilities

Grant will demonstrate improved integration of renewables through energy storage and information technology, improve reliability, and reduce the costs of intermittent renewable or distributed energy.
Avista was awarded a $3.2-million grant from the state to field test a 1-MW, 3.2-MWhr UniEnergy vanadium-flow battery assembly in a three-year demonstration project at a substation in Pullman, Wash. Total project cost, as proposed, exceeds $7.6 million.
Puget Sound Energy was awarded a $3.8 million grant from the state to help deploy a 2-MW, 4.4-MWhr lithium-ion/phosphate battery assembly at a substation in Glacier, WA. Total project cost, as proposed, exceeds $12 million. 
Snohomish PUD was awarded $7.3 million in state grants for multiple demonstration projects. The PUD has been working with Seattle-based 1Energy Systems for the past two years to implement Modular Energy Storage Architecture, a set of nonproprietary design and connectivity standards that provide a scalable approach for energy storage control system integration and optimization. Total project cost, as proposed, exceeds $23.4 million. 
  • The MESA 1 project will deploy two 1-MW, 500-MWhr lithium-ion battery based systems within one substation. These two large-scale lithium-ion battery assemblies, one built by LG Chem and a second by Mitsubishi-GS Yuasa, will each use a Parker Hannifin Power Conversion System. The battery assemblies were dedicated on January 15, 2015.
  • The MESA 2 project, at a different substation, will deploy multiple advanced vanadium-flow battery assemblies, built by UniEnergy Technologies, having total combined ratings of 2MW/6.4MWhr.
Pacific Northwest National Laboratory was awarded $695,000 in state funds to perform use case analysis on all the systems described above.  

Federal Grant Matching Funds 

These grants are for Washington research institutions, including colleges, universities, federally funded research and development centers, and any other entities able to demonstrate continuous and intensive engagement with the research community, preferably through both a publication history in academic literature, and success in patenting and licensing relevant technology.

  • Three applicants (proposals exceed $1.84 million) are in contract negotiations. 
  • Eight applicants (proposals exceed $8.6 million) are waiting for federal grant award notifications.
  • Six applicants (proposals exceed $18.5 million) did not receive federal awards.

No additional funding is available at this time. All funds are currently committed for submitted proposals. Should one or more of these proposals not be successful, we will give notice of funding availability.

Returning Recovery Act Funds

Commerce is authorized to expend up to $4 million in new loans generated from returned federal recovery act energy funds. No funding is available at this time and are dependent upon the timing and volume of federal loan repayments.
