High-Efficiency Cogeneration

Dual applications that combine thermal and electrical energy for more efficient systems

combined solutions
We rethink thermal generation with solutions that maximize energy production

Cogeneration is a technology that allows the simultaneous production of thermal energy (heat or steam) and electrical energy from a single fuel source, significantly improving the overall energy efficiency of the process. Compared to conventional systems, which generate heat and electricity separately with higher losses, cogeneration can utilize up to 80–90% of primary energy, thus reducing both consumption and emissions.

This system is particularly suitable for industrial sectors with a high and continuous thermal demand, such as the paper, food and beverage, chemical, textile, plastic, pharmaceutical, or metallurgical industries, among others. In these environments, cogeneration ensures efficiency, supply stability, reduced operating costs, and tangible improvements in sustainability and carbon footprint indicators.

Thanks to our ESCO model (Energy Service Company), at ENSO we design, finance, build, and operate cogeneration facilities tailored to the real needs of each industry — without requiring any initial investment from the client.

Solution conceptualization

Higher overall
system
efficiency

In traditional power generation systems, a large portion of the fuel’s energy (up to 60%) is lost as heat during the process. In contrast, cogeneration recovers that heat and reuses it to meet thermal needs such as heating, cooling, or industrial processes. This allows the total system efficiency — combining both the useful electrical and thermal energy produced — to reach levels between 70% and 90%, compared to 35–45% in conventional power plants. This superior efficiency translates into more rational fuel use, reduced total energy consumption, and therefore lower CO₂ emissions per unit of energy generated.

Recovery
of residual
heat

In industrial environments, cogeneration stands out for its ability to recover residual heat generated during the combustion of engines or turbines and reuse it directly in production processes, without the need for additional thermal sources. This heat can be utilized as high-pressure steam, widely used in processes such as sterilization or distillation — common in industries like food and pharmaceuticals. It can also be used as industrial hot water for cleaning tasks, or as hot gases directly channeled to furnaces or dryers, especially in sectors such as paper or ceramics. In processes that require precise thermal control or constant high temperatures — as in the chemical or textile industries — the recovered heat can be transferred to provide high thermal stability and efficiency. In all these cases, the recovery of residual heat not only reduces the consumption of conventional fuels and associated energy costs but also increases the overall efficiency of the system and enhances the plant’s competitiveness. Furthermore, by integrating directly into industrial infrastructure, it reduces thermal energy transport losses and enables more efficient, localized management of the energy resource.

Flexibility
to meet
energy
demands

One of the main strengths of cogeneration is its high capacity to adapt to different energy demand profiles, both in terms of scale and in the balance between thermal and electrical consumption. This technology can be implemented on a large scale in industrial sectors with continuous and demanding thermal processes, such as food, chemical, or paper industries, where a constant and efficient supply of heat and electricity is required. It is also perfectly viable on a small or medium scale, in environments where thermal needs can be met in a decentralized way. In addition, many of our cogeneration systems allow for modulating operation — that is, they can dynamically adjust electrical and thermal output according to real-time demand. This responsiveness makes cogeneration an especially valuable technology for reducing energy consumption peaks, flexibly complementing other intermittent renewable sources — such as solar or wind — and contributing to the stability of local energy networks.
