Bright Power, a New York City-based energy management provider, is purchasing Ecological Partners, an energy efficiency service provider previously owned by Root9b Technologies. The value of the deal was not disclosed.

Bright Power provides energy services for real estate portfolios nationwide, including energy benchmarking, energy auditing, resiliency solutions and energy procurement. The acquisition of Ecological Partners, whose primary focus was energy-related local law compliance, enhances Bright Power’s existing business and incorporates a competitor, according to the company.

Bright Power views Ecological’s success in the compliance market as a stepping-stone to more in-depth energy efficiency projects. With the addition of Ecological’s client base, Bright Power now provides local law compliance services to over 1,000 buildings in New York City.
