CHP / Cogeneration
Combined heat and power (CHP), or cogeneration, generates electricity and useful heat from a single fuel input, capturing heat that a conventional power plant would waste. It can reach high total efficiency where there is a steady on-site heat demand.
CHP units (gas engines, turbines) produce power on site and recover the engine or exhaust heat for process steam, hot water or space heating. Because they use heat that would otherwise be rejected, total fuel efficiency can be much higher than separate power and heat — but only where heat demand is steady and coincident with generation.
In context and practice
In practice, chp / cogeneration spans both strategy and software. It is central to guides like Waste heat recovery in industry, Factory decarbonization: a practical roadmap, and essential to how Schneider EcoStruxure and similar platforms operate. Plants use chp / cogeneration to bridge operations and technology decisions.
Closely related terms include Waste Heat Recovery, Energy Management System (EnMS / EMS), Industrial Decarbonization. These concepts often work together in industrial practice — mastering one usually means understanding all of them.
In your plant: When planning maintenance, reliability or efficiency projects, clarify your approach to chp / cogeneration. Ask vendors or consultants how they implement it. The specifics matter — two plants with the same definition of chp / cogeneration may execute it very differently based on their equipment, age, and operational culture. The gap between definition and execution is where real value (or waste) lives.
Measuring success: Chp / cogeneration programs succeed when you can measure their impact. Set a baseline, implement the practice, and track the outcome — downtime reduction, energy savings, cost avoidance, or compliance improvement. Most plants find that a 3–6 month pilot clarifies the true value and ROI of chp / cogeneration. Don't guess; measure.
Why it matters: chp / cogeneration is not an end in itself, but a lever in your plant's overall efficiency and reliability strategy. It works best when part of a system: clear ownership, investment in tools or training, executive sponsorship, and regular review. Isolated initiatives often fizzle. Embedded chp / cogeneration programs compound, delivering value year after year as the practice matures and spreads.
