Gemspring Backs Utility Contractors Key Line Construction and Palouse Power

Gemspring Capital has completed a partnership combining Key Line Construction and Palouse Power into a single utility infrastructure services platform, marking a consolidation move in the fragmented Pacific Northwest contractor market. Key Line, headquartered in Oregon, and Palouse Power, based in Washington, are regional specialists in building and maintaining the physical infrastructure that transmits electricity from generation sources to end users. The combined company operates across five states—Oregon, Washington, Idaho, California, and Utah—and employs more than 250 people.

The merger creates a differentiated operator through complementary capabilities. Key Line is among the few regional contractors capable of self-performing both electrical work and civil work (excavation, foundations, site preparation) on a single project, enabling operational flexibility on demanding assignments in remote terrain. Palouse Power brings strength in managing planned utility capital programs alongside emergency restoration services following storms and outages. Together, the platform will serve investor-owned utilities, federal power agencies, electric cooperatives, and public utility districts across distribution lines, high-voltage transmission, substations, and communications infrastructure.

Leadership continuity is maintained through Tank Parrish, CEO of Key Line, and Jeff Zimmer, President of Palouse, who will co-lead the combined entity. Both executives emphasized operational synergies: Parrish highlighted access to additional resources, expanded geographic reach, and deeper talent pools, while Zimmer stressed the ability to broaden service offerings and geography while creating advancement opportunities for employees across both organizations.

Gemspring's investment thesis centers on structural tailwinds supporting long-cycle utility spending. Utilities nationwide are modernizing aging infrastructure, extending distribution networks to serve new development, and hardening equipment against weather and wildfire risks. Demand acceleration is being driven by electrification of vehicles and buildings, coupled with data center construction and increased electricity consumption. The utility contractor market remains highly fragmented, with few operators capable of executing multi-state work at scale—creating consolidation opportunity. Alex Shakibnia, managing director at Gemspring, characterized the market as "large, fragmented, and supported by multi-decade secular tailwinds," positioning the combined Key Line-Palouse platform as a scaled competitor in this structural growth environment. Piper Sandler served as financial advisor to Gemspring on the transaction.
