LS Power, a prominent development, investment, and operating firm focused on North America’s power and energy infrastructure, has officially completed its acquisition of ENGIE Services U.S., marking a significant expansion of its capabilities in energy services. Following the acquisition, ENGIE Services has reverted to its former name, OPTERRA Energy Services. With over five decades of operational experience, OPTERRA brings a robust legacy to LS Power’s existing portfolio, reinforcing its mission to deliver reliable, cost-effective, and forward-thinking energy solutions.
OPTERRA offers a comprehensive suite of services, including energy efficiency upgrades, renewable energy systems, energy storage, microgrids, HVAC and lighting solutions, ongoing operations and maintenance, as well as measurement and verification services. Since its founding in 1974, the company has executed more than 9,000 projects across the North American public sector. Key accomplishments include the modernization of 72,000 streetlights in the District of Columbia, the deployment of 8.1 megawatts of solar capacity across 48 sites with a microgrid backup system for the Chula Vista Elementary School District, and an integrated energy and water savings initiative for the City of Milpitas, which is expected to save over $30 million.
OPTERRA’s client base spans a wide range of public entities, such as the U.S. Department of Veterans Affairs, Broward County in Florida, the City of Arlington in Texas, and the Oregon Community Unit School District in Illinois. In total, the company has delivered 375 megawatts of solar power and is currently managing 24 active microgrid projects, supporting municipal, county, federal, and educational institutions. Now part of LS Power’s growing family of energy infrastructure companies, OPTERRA complements the firm’s ongoing efforts to enhance energy efficiency and grid reliability. LS Power’s portfolio includes a range of projects that span renewables, flexible gas generation, and customer-focused demand-side solutions—all contributing to a more robust and adaptable energy system.
Paul Segal, CEO of LS Power, “Meeting America’s growing energy demand will require a ‘more-of-everything’ approach—and the energy services market is an integral piece of that puzzle. The addition of OPTERRA brings a rare combination of leadership talent, technical expertise and trusted customer relationships that enhance LS Power’s energy solutions platform. Their cutting-edge capabilities in energy efficiency services and low-carbon offerings are a strategic fit as we continue to expand our portfolio of power and infrastructure solutions.”
Courtney Jenkins, CEO of OPTERRA Energy Services, stated, “Reintroducing OPTERRA under LS Power marks an exciting new chapter for our legacy team dedicated to serving the public sector. We’re building on a proven foundation to deliver innovative, leading-edge technology solutions that make energy efficiency and low carbon projects accessible and impactful. Through our unique range of in-house experts, we empower our customers to meet aggressive goals around financial savings and energy resiliency that have a positive ripple effect across the communities we serve, fueling accelerated growth for both our customers and our mission.”
Headquartered in Oakland, California, OPTERRA employs nearly 300 professionals and has already helped customers achieve over $3 billion in guaranteed energy cost savings. The acquisition was finalized on June 12, 2025, following the fulfillment of all customary closing conditions, including regulatory approvals in the U.S. This strategic move positions LS Power to further advance its role in the transition to smarter, cleaner, and more resilient energy infrastructure across the country.
