Broad Sky–backed Commonwealth Electrical Technologies acquires Horton Electrical Services, nearly doubling its Northeast workforce

Commonwealth Electrical Technologies (“CET”), a Worcester, Massachusetts–based electrical and energy infrastructure contractor, announced on September 15 that it has acquired Horton Electrical Services, a third-generation electrical and civil services contractor based in Connecticut. The deal expands CET’s Northeast footprint and adds specialized work in wastewater infrastructure, solar, and civil construction. With Horton on board, CET says its workforce has nearly doubled. Warren Horton continues to lead the Horton business, reporting to CET’s leadership. Broad Sky Partners became CET’s majority investor in February 2025.

The asset.

Horton Electrical Services was founded in 1976 by Arthur Horton. Warren A. Horton joined as an apprentice in 1994 and later became owner and Managing Member. The company provides electrical construction for wastewater treatment facilities and pump stations, solar installation, operations and maintenance, generator services, civil site work, and around-the-clock emergency response across Connecticut and the broader Northeast. It employs more than 100 field staff and 20 managers.

That is a specialty commercial and infrastructure electrical book — project and O&M work on wastewater and solar, plus generators and civil.

The platform.

Commonwealth Electrical Technologies was founded in 2008 and is headquartered in Worcester, with additional operations in Taunton, Massachusetts. Per its site and Broad Sky’s portfolio description, CET provides electrical construction, energy efficiency, solar installation and maintenance, and EV charging for commercial, industrial, institutional, utility, and renewables customers across New England (licensed in Connecticut, New Hampshire, Maine, Massachusetts, Rhode Island, and Vermont). The company has described itself as a team of roughly 160 professionals before this deal.

In February 2025, Broad Sky Partners became CET’s majority investor, partnering with management to fund growth and expansion. John Duquette, Jr., CET’s chief executive, framed Horton as a transformational step that immediately strengthens what CET can offer customers while sharing a commitment to safety, craftsmanship, and people.

Specialty density in a PE-backed Northeast electrical platform.

A Broad Sky–backed commercial and energy electrical platform is buying a third-generation Connecticut specialty contractor and nearly doubling headcount in one move — with the seller staying to run the brand.

Owners have seen commercial electrical consolidation at a larger scale in Kohlberg-backed Loenbro’s Prism Electric deal and in public consolidators such as Limbach’s 1901 Inc. purchase. CET/Horton is the lower-middle-market Northeast version: wastewater and solar specialty capabilities, operator continuity, and a sponsor already a year into the platform build.

What it means.

For Northeast commercial and industrial electrical owners — especially shops with wastewater, solar O&M, or generator books — a Broad Sky–backed platform is actively adding specialty density and saying the combined team can take larger, more complex work. The practical questions on the next inbound are familiar: how much of the book is recurring O&M versus project install, whether the buyer wants pure electrical or civil-and-infrastructure adjacent work, and whether Horton-style operator continuity is on the table.

Residential service platforms, commercial MEP consolidators, and energy-infrastructure electrical buyers are all active. They are not the same inbound.
