Key Line Palouse Power merger creates utility services platform

Key Line Palouse Power will operate as a combined utility infrastructure services platform after Gemspring Capital-backed Key Line Construction merged with Palouse Power, PE Hub reported. Financial terms of the transaction were not disclosed, leaving the deal’s valuation and ownership economics outside the public record.

The combination brings together Roseburg, Oregon-based Key Line and Quincy, Washington-based Palouse, two companies that provide construction and maintenance services for utility infrastructure. According to PE Hub, the merged company will serve utility customers across Oregon, Washington, Idaho, California and Utah.

The deal places the combined business in a market tied to electricity networks and related communications infrastructure, where utilities rely on outside contractors for field work, maintenance and project execution. For financial sponsors, these services can fit a platform strategy because recurring infrastructure needs can support acquisitions and operational integration, though PE Hub did not report any future acquisition plans for the company.

What does the Key Line Palouse Power merger include?

The merged company combines services across electric distribution, transmission, substations and communications infrastructure, according to PE Hub. In practical terms, that means the business works on the physical systems that move power through local and regional grids, as well as related network assets.

PE Hub reported that Tank Parrish and Jeff Zimmer will lead the combined company. The report did not specify their titles in the newly formed business.

Gemspring’s backing of Key Line makes the transaction part of the private equity firm’s activity in energy and power services. A private equity-backed platform is a company used by a sponsor as a base for growth, either through operations, acquisitions or both. In this case, the disclosed facts show the platform has been formed through the merger of Key Line and Palouse Power.

Alex Shakibnia, managing director at Gemspring, said the market for critical utility infrastructure services is “large, fragmented, and supported by multi-decade secular tailwinds.” He also said Tank Parrish, Jeff Zimmer and their teams had built businesses with “a shared commitment to safety, quality, and their people.”

Piper Sandler advised Gemspring financially on the transaction, according to PE Hub. McDermott Will & Schulte LLP served as Gemspring’s legal adviser.

The transaction adds to private equity activity around grid-related services, a field shaped by utility maintenance requirements and investment in electric infrastructure. PE Hub did not report the date of closing, revenue figures, employee numbers or customer names for the combined company.
