Cogeneration

Cogeneration is a technology for the combined generation of thermal energy and electric energy. It is also popular under the name of combined heat and power, abbreviated as CHP. The technology requires a primary energy source, the most widely used currently being natural gas, diesel fuel, biomass and biogas. It is constantly evolving so even innovative hydrogen installations are already being tested for the market.

Who can use cogeneration?

Cogeneration systems, also called cogeneration plants, are suitable for a
wide range of energy consumers and represent one of the most efficient energy technologies available today. They have the capacity to provide all the energy needed in a factory, a farm, a hospital, a shopping mall or an airport, among many others.

Combined heat and power is also an environmental and resource efficiency upgrade for many older district heating utilities and thermal power plants which so far generate only heating or only electricity.

How it works

The most widely used technologies for combined heat and power are designed around internal combustion engines, gas turbines, and steam turbines, and there is an innovative approach integrating fuel cells which is also gaining popularity. Each technological solution is most efficient in its own segment of energy consumers depending on their size. The largest energy consumers are best served by turbine-based CHP, the smallest – by fuel-cell micro CHP, and in the middle lies the internal combustion engine CHP.

Internal combustion engine CHP

Termogamma® is specialized in cogeneration plants which are based on internal combustion engine technology, as it is the most efficient solution for energy consumers in the range of 20 kW to 2 MW of electricity. These are anywhere from a larger family residence, hotel, hospital, school, university, etc. to a manufacturing industry.

The manufacturing industries which can have the greatest benefit from a cogeneration solution are the plastic, chemical, pharmaceutical, and food factories, even though any building which consumes electricity and heat at the same time can benefit from it.

Cogeneration Maintenance

Cogeneration plants based on internal combustion engines require regular maintenance, just like cars do – change of oil, filters and spare parts, along with more complex interventions based on a fixed time schedule. Proper maintenance guarantees the long useful life of a cogeneration plant and its optimum performance.

To ensure better and faster maintenance, Termogamma® has developed a real-time remote monitoring and control software which keeps track of all essential parameters of the system’s operation.

Models and features

Energy efficiency is maximum when every system is designed and constructed for its end-user in order to suit the particular energy needs. Thus Termogamma® has chosen to work in the tailor-made solutions segment rather than to produce fixed sizes and models. This ensures that the end user will pay for only what they need, nothing more and nothing less.

Termogamma®’s engineers in collaboration with the client’s technical experts select the most suitable engine brand and size for each client after a careful analysis of the energy mix, annual consumption, energy prices, load fluctuations and many other factors. For that analysis, we have developed a dedicated checklist of the necessary data.

Evaluation

You can reduce your energy consumption, and respectively energy costs, by as much as 40% through cogeneration. Start your evaluation by considering the following favorable criteria:

  1. Do you have natural gas or other fuel (diesel, LPG, biomass, biogas) readily available, and is it less expensive than electricity in your country?
  2. Do you consume large amounts of energy, moreover, for many hours a day?
  3. Do you consume electricity and heat simultaneously? Can you sell electricity to the state at a preferential price (feed-in tariff)?
  4. Does your country offer subsidies for energy efficiency and reduced carbon emissions?

As this is just a starting point in the evaluation, do not hesitate to contact us for a detailed analysis and consultancy on cogeneration feasibility for your environment send us an enquiry.
