Worcester-based Commonwealth Electrical Technologies has acquired Connecticut-based Horton Electrical Services, bringing more than 120 Horton employees into the electrical contractor that was recently backed by a private equity firm.
The acquisition nearly doubles CET’s workforce and expands the company’s capabilities in wastewater infrastructure, solar energy, and civil construction, CET announced last week.
Financial terms of the purchase were not disclosed.
Founded in the late 1970s, Horton provides electrical construction work for wastewater treatment facilities and pump stations, solar installation and operations and maintenance, generator services, civil site work, and 24-hour emergency response. Horton employs more than 100 field staff members and 20 managers.
Horton serves commercial, industrial and infrastructure clients across Connecticut and the Northeast. Warren Horton, the company’s third-generation owner and managing member, will continue to lead the business and report to CET’s leadership team.
“This is a transformational step in CET’s growth and an exceptional fit for both organizations,” John Duquette, CET CEO, said in the announcement. “Horton brings 50 years of experience, an outstanding team, and highly specialized capabilities that immediately strengthen what we can offer our customers.”
CET was founded in 2008 and provides electrical construction, energy-efficiency, solar and electric vehicle-charging services for commercial, industrial and institutional customers. The company is headquartered in Worcester and has an additional office in Taunton.
The acquisition comes after New York City private equity firm Broad Sky Partners became CET’s majority investor in February 2025.
Broad Sky invests in middle-market companies providing business services. Other companies in its portfolio include New Jersey-based scientific equipment supplier Thomas Scientific and Washington, D.C.-based communications agency Bully Pulpit International.
CET has used that backing to expand its business through acquisitions. In October 2025, CET acquired NuWave Energy Solutions, a Norwell-based energy conservation firm.
Horton will be able to pursue larger and more complex projects while retaining its existing customer relationships, Horton said in the announcement.
“Joining CET gives our team the resources and scale to pursue larger, more complex projects, invest further in our people, and expand into new markets without losing what has made Horton successful,” Horton said.
