By deeply engaging and understanding specific goals, we deliver on the mission our customers envision. From 2016 -- 2025, OPTERRA Energy Services was previously owned by global energy company ENGIE, doing business as ENGIE Services U.S. In June 2025, national energy giant LS Power acquired the former ENGIE Services U.S. team and OPTERRA returned to its legacy name in the market. --- OUR MISSION To deliver Innovative and sustainable energy solutions that empower communities and businesses, leveraging our expertise and commitment to excellence to drive a cleaner, more efficient future. OUR STORY Starting as a core group of engineers with a handful of patents, OPTERRA has become a national energy company with a rich history of industry leadership and high performance. 50 years of practice unifying strong legacy companies, from Consumers Energy to PG&E, Bluestone, Chevron Energy Solutions, and ENGIE, have allowed us to evolve with our customers and become a leader in energy efficiency, renewables, and infrastructure development. OUR APPROACH There are opportunities in almost every facility to reduce energy consumption and energy cost. Our teams are dedicated to building comprehensive technical scopes that are unique to our customers’ energy needs, allowing our partners to save valuable finances and other resources that can be redirected to address other, mission-critical business priorities.
