Saber Power Services
Greenbelt's 2023 investment in the engineering-led platform that designs, builds, tests, and maintains substation and medium-to-high-voltage infrastructure the U.S. grid runs on.

Substations are where the grid does its most critical work — stepping voltage up and down, routing power, protecting the network. As electrification, renewables, and load growth strain the system, demand for new and upgraded substation capacity has outrun the supply of firms that can deliver it end to end.
Saber Power Services, founded in 2010 and headquartered near Houston, is one of the few that can. It takes an engineering-led approach across the full lifecycle — design, construction, testing and commissioning, maintenance, and 24/7 emergency response — for medium- and high-voltage systems serving utilities, data centers, renewables and storage developers, and large industrial customers.
Greenbelt led the investment in Saber in 2023, backing a platform positioned at one of the grid's hardest to address bottlenecks. It is a direct expression of the firm's grid-enablement thesis: the energy transition needs physical infrastructure built and maintained by specialists, and Saber is the specialist.
From Specialist to Full-Scope Partner
Greenbelt Leads the Investment
A Greenbelt-led investor group acquires Saber Power Services, providing capital and a scaling partner for a national substation and high-voltage infrastructure platform.
Acquiring inoLECT
Saber acquires inoLECT, broadening its electrical engineering, testing, and power-systems capabilities and deepening the work it can self-perform.
Acquiring Bounds Construction
Saber acquires Bounds Construction II, adding substation and switchyard foundation, piling, and specialty-foundation capabilities — letting the company self-perform earlier phases of every project.
End to End on the Grid
Through a family of specialized businesses, Saber delivers turnkey substation and high-voltage services nationwide — engineering, construction, testing, and lifecycle support under one platform.
Owning More of the Critical Path
The most valuable infrastructure partners are the ones that can take a project from engineering through energization without handoffs. Saber has been building toward exactly that — and its 2026 acquisition of Bounds Construction extends the platform into the foundation and civil scope it previously subcontracted, compressing schedules and capturing more of each project's value.
It is the same compounding logic that runs through Greenbelt's grid investments: back a platform with a defensible core, then help it broaden into the adjacent capabilities its customers already need.
“What Greenbelt brought was strategic clarity. They had a real understanding of where our opportunities were, a framework for how to go after it, and the discipline to make sure we're winning the right work at the right margins. Greenbelt helped to build a go-to-market approach with the management team, and our people run it now. That's what good partnership looks like.”Brian Bratton · CEO, Saber Power Services

Built Where the Grid Is Built
Every renewable interconnection, every data-center load, every grid upgrade runs through a substation someone has to design, build, and keep running. Saber Power is that someone — an engineering-led platform at the center of grid modernization, and a clear expression of how Greenbelt invests in the infrastructure that powers what's next.
