Westwood Professional Services, a Plano-based engineering and design firm, has received a majority investment from New York City-based Blackstone, and equity funds affiliated with Blackstone.

Established in 1971, Westwood is a full-service professional engineering firm specializing in wind energy, solar energy, energy storage, power delivery, EV infrastructure, commercial, institutional, residential, and public infrastructure projects. Its team of more than 1,600 employees work out of more than two dozen offices nationwide.

Financial terms of the investment were not disclosed.

Blackstone said it will acquire its position in Westwood from Endurance Partners, with Westwood’s management team and employee shareholders retaining a minority stake.

“Throughout its 50-plus year history, Westwood has sought to enhance communities by providing critical engineering and design services to our clients,” Westwood CEO Bryan Powell said in a statement. “We’re excited about this new partnership with Blackstone as it positions the company to continue expanding its capabilities in Westwood’s key end markets of renewable energy, power, land development, and public infrastructure, which are each poised to benefit from long-term growth tailwinds.

“We appreciate the support of Endurance Partners in helping scale Westwood into the business that it is today,” Powell added.

Powell was named CEO of Westwood last September after the retirement of former leader Paul Greenhagen. The company had been headquartered in Minneapolis, Minnesota, before relocating its HQ to Plano late last year.

Supporting the ‘increasing adoption of renewables’ and investment in power systems

Westwood provides front-end engineering design services supporting the development of renewable energy generation, investment in the power grid, and the continued buildout of public and private infrastructure across the nation.

“Westwood provides crucial expertise and resources to support the increasing adoption of renewables and investment in power systems throughout the U.S. and is well positioned to continue building upon its impressive growth,” Darius Sepassi, senior managing director, and Mitchell Nimocks, managing director, at Blackstone Energy Transition Partners, said in a joint statement. “We look forward to combining the power of Blackstone’s global scale and resources with Westwood’s talent to expand and enhance its valued partnerships with new and existing clients across the renewables, power, land development and public infrastructure value chains.”

David Foley, global head of Blackstone Energy Transition Partners, said the firm has made a big commitment with the investment.

“Our partnership with the exceptional Westwood management team builds upon our recent energy transition investments including Trystar and Sediver, providing critical services and equipment needed to facilitate the transition to more reliable, affordable and cleaner energy. With the signing of this investment, Blackstone Energy Transition Partners will have committed approximately $1.3 billion in control-oriented equity investments in the energy transition since June,” Foley said.
