About Obsidian

A recognized leader in Pacific Northwest renewable energy, green hydrogen and clean fuel infrastructure development

Our Developments

Obsidian is currently advancing multiple projects to deliver long-duration energy storage and low-carbon, low-emission fuels to customers in Oregon, Washington and Idaho. Several of these facilities are being developed to supply clean electricity and clean burning gas to the  power sector as the region seeks to rapidly decarbonize its grid while wholesale loads grow. A subset of these sites will also produce eMethanol and other alternative fuels for maritime shipping and west coast transportation.  Additionally, Obsidian has 500 MW of utility scale solar and BESS projects in operation or late-stage development in Oregon.  


Pacific Northwest Legacy

Twenty Years and Counting

Obsidian operates from a long-standing position of leadership in the Pacific Northwest renewable energy sector. Our organization is shaped by a legacy of innovation dating back to 2003 with the pioneering of utility scale solar projects in the state of Oregon beginning in 2008. We are proud to have developed the first utility-scale solar energy facility in Bonneville Power Administration’s service territory, as well as the first solar facilities in PGE’s and PacifiCorp’s generating portfolios. Over the last two decades, Obsidian has grown into the largest independent Oregon-based developer of utility scale solar facilities and has built a community of trusted alliances that lead the region’s clean energy transition.  We are long-standing members of the Community Renewable Energy Association (“CREA”) (serving on the Board of Directors), the Northwest and Intermountain Power Producers Coalition (“NIPPC”), the Solar and Storage Industries Association (“OSSIA”) and founding members of the Renewable Hydrogen Alliance (“RHA”).

Regional Leadership

Today, Obsidian sits at the center of the Pacific Northwest’s expanding hydrogen ecosystem.  In 2023, Obsidian received direct encouragement from the US Department of Energy in connection with its hydrogen hub proposal for Oregon and Washington.  Obsidian’s team, based in Portland, holds unique expertise in “Power-to-X” and “BECCS” (biomass with carbon capture and storage) projects, as well as, thermochemical conversion processes for the production of alternative clean fuels.  We complement in-house development and engineering expertise with close technical partnerships in the areas of electrolysis, hydrogen fuel cells, combustion turbines and reciprocating engines.


Comprising highly experienced professionals in the areas of renewable energy development, transmission, tax, law, finance, engineering and data science, Obsidian is a well-respected and influential voice on regional energy policy and a highly reliable development partner in the PNW region.
