Energy Systems Group

What Energy Systems Group does

Energy Systems Group (ESG), founded in 1994 and headquartered in Newburgh, Indiana, is a NAESCO-accredited Energy Savings Performance Contract (ESPC) provider and wholly-owned subsidiary of CenterPoint Energy, Inc. (since the 2019 CenterPoint-Vectren merger). The company delivers infrastructure modernization and energy solutions across three core service pillars: Energy Efficiency (HVAC, building automation, retrocommissioning, building envelope, lighting, water conservation, indoor environment quality), Resiliency (distributed energy resources, combined heat & power, microgrids, energy storage, power quality), and Alternative Energy (solar, carbon capture, waste heat recovery, renewable natural gas, biomass, geothermal). Supporting capabilities include engineering, design-build, construction management, operations & maintenance, measurement & verification, and energy consulting.

ESG serves federal/military (Hill AFB, Fort Bragg, Marine Corps bases at Camp Lejeune, Barstow, Blount Island, Coast Guard Portsmouth, NASA Glenn), K-12 schools (Antelope Valley, Perry Township, Oceanside), higher education (Atlanta University Center, Palos Verdes Peninsula USD), local/state government (Lemoore CA, Leon County FL, Licking County OH), healthcare (North Chicago VA), corrections, commercial/industrial (PVS Chemicals), transportation (Nashville International Airport), wastewater utilities (Altoona Water Authority), and utility partners. Project economics rely on 15-25 year performance contracts where capital improvements are funded through guaranteed future energy and operational savings, with ongoing O&M and M&V revenue streams.

ESG distributes exclusively through direct enterprise field sales via consultative, technical engagement. In 2024 the company completed two acquisitions (PacificWest and Yearout Energy Services) to broaden geographic and capability reach, and in 2025 was selected alongside GE Vernova, Sage Geosystems, and the University of Utah's Energy & Geoscience Institute to deliver advanced geothermal and hydrogen solutions for DoD installations. Headcount is 251-500; leadership transitioned in March 2025 with Jeff Blum appointed CEO.

• Honeywell Building Technologies: Honeywell's building technologies division competes with ESG in energy efficiency retrofits, building automation, and energy performance services for government and institutional clients, but operates as part of a much larger industrial conglomerate.
• Schneider Electric: Schneider Electric provides energy management, microgrid, and ESPC-adjacent services through its Sustainability Business, competing with ESG in federal energy resilience projects but as part of a global energy management portfolio.
• Siemens Smart Infrastructure: Siemens Smart Infrastructure offers building automation, energy services, and microgrid solutions for institutional and government customers, overlapping with ESG's resiliency and efficiency offerings as part of a much broader smart infrastructure portfolio.
• Trane Technologies: Trane Technologies delivers HVAC, building services, and energy performance contracting for institutional and government customers, serving as a broad incumbent competitor to ESG's mechanical systems and energy efficiency work.

Emerging players

• ICF International: ICF International provides energy consulting, decarbonization advisory, and infrastructure modernization services for federal and utility clients, competing with ESG's energy consulting and ESPC support work but with a more advisory-led model.
