The company traces its roots to 1964 and has accumulated over 50 years of experience in reciprocating engine power applications.

NES-WES functions as a distributor and systems integrator for combined heat and power (CHP) and distributed generation (DG) solutions. A staff of 200–499 employees handles integration engineering, field project management, commissioning, and ongoing maintenance. The company serves institutional, commercial, and governmental customers across the energy, utility, industrial, and commercial sectors. Project references include the Bergen County Wastewater Treatment plant, Covidien’s New Haven CHP installation, Mount Joy Wire, a landfill-gas-to-energy facility, High Sierra California Cogeneration, and Techni-Cast industrial cogeneration. NES-WES emphasizes reducing energy costs, increasing resilience, and lowering carbon footprints for its clients.
