Sterling Energy Group

What Sterling Energy Group does

Sterling Energy Group, LLC is a privately held, Atlanta-based energy engineering consultancy founded in 1998, serving electric utilities, major industrial clients, and institutional customers across North America and select international markets. The firm specializes in Combined Heat and Power (CHP or cogeneration) and broader energy efficiency, with additional practice areas in biomass, Organic Rankine Cycle, wind, and solar photovoltaic. Its core offerings include CHP site identification and evaluation, thermodynamic and performance modeling, Levelized Cost of Energy (LCOE) analysis, owner's engineering and project oversight, conceptual design, and optimization of existing cogeneration facilities.

The company's underlying technology is engineering-domain modeling rather than software: rigorous thermodynamic modeling, performance simulations, and economic analysis used to evaluate CHP configurations, alternative generation technologies, and improvement scenarios for existing facilities. Sterling also supports the full development cycle from conception and feasibility through design review, procurement oversight, startup, and commissioning. The firm was a founding partner of Turkish Wind Partners, an early wind developer in Turkey whose Kores Wind park was sold to Dost Enerji.

Sterling's business model is professional services: project-based consulting engagements priced through direct enterprise sales, with revenue tied to the volume and size of feasibility, owner's engineering, and optimization assignments. The firm has 51–100 employees and a 20+ year operating history, drawing on staff with 40 years of power-generation experience. Marketing and distribution are relationship-driven with no public digital presence, and the company is founder/management-owned with no disclosed institutional capital.

Products and services

• Combined Heat and Power (CHP) Advisory Expertise Identification and evaluation of potential thermal host sites, including evaluation of process requirements and site data; preliminary design and performance modeling of alternative technologies and configurations; identification and documentation of values to all parties including utility, thermal host, customers, and regulators. Targeted at utilities and major industrial/institutional clients considering CHP/cogeneration.
• Owner's Engineering & Project Oversight Project scope, schedule, and design review; review of Mechanical, Electrical, Structural, Civil and Environmental designs; coordination with design and construction organizations; procurement oversight and tracking; review and monitoring of startup and commissioning plans. Provided to project owners (typically utilities and large industrial clients) across the development and execution cycle.
• In-Depth Development and Project Support Conceptual design, performance modeling, and efficiency analyses; development of budgets for project development, operation, and maintenance; determination of Levelized Cost of Energy (LCOE) for various alternatives. Serves utilities and industrial/institutional clients evaluating energy efficiency, CHP, and renewable generation options.
• Optimization of Existing CHP Evaluation of planned and existing industrial and institutional cogeneration facilities; development of rigorous thermodynamic models to evaluate improvement scenarios; comprehensive energy cost modeling to determine lowest cost of operation for any scenario. Targeted at owners/operators of existing CHP assets.
• Biomass & Organic Rankine Cycle (ORC) Advisory Co-firing assessments and energy crops; efficiency improvements of biomass boilers; generation in wood products plants and evaluation and development of biomass-fired generation. Provided to utilities and industrial clients exploring biomass and ORC solutions.
• Wind & Solar Photovoltaic (PV) Advisory Wind and solar generation assessment as part of customer and electric utility planning and Levelized Cost of Energy analysis; historical involvement in Turkish wind projects through Turkish Wind Partners. Targeted at utilities and large customers evaluating wind and solar PV generation.
