LS Power, a leading U.S. energy infrastructure company, has completed its acquisition of ENGIE Services U.S. Following the transaction, the business will return to its former name, OPTERRA Energy Services, reviving a brand with more than five decades of experience in delivering clean and efficient energy solutions.
OPTERRA provides a wide range of energy services, including energy efficiency upgrades, renewable energy systems, energy storage, microgrids, operations and maintenance, HVAC and lighting systems, and performance measurement and verification. “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,” said LS Power CEO Paul Segal, commenting on the acquisition.”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.”
Since its founding in 1974, OPTERRA has completed more than 9,000 public sector energy projects across North America. Notable initiatives include the modernization of 72,000 streetlights for the District of Columbia, an 8.1-megawatt solar program across 48 sites for Chula Vista Elementary School District in California—complete with a microgrid for backup power—and a comprehensive energy and water savings program for the City of Milpitas, projected to save over $30 million.
