Understanding Cogeneration
Cogeneration, also known as Combined Heat and Power, or CHP, is the production of electricity and heat in one single process for dual output streams. In conventional electricity generation 35% of the energy potential contained in the fuel is converted on average into electricity, whilst the rest is lost as waste heat. Even the most advanced technologies do not convert more than 55% of fuel into useful energy |
 |
Cogeneration uses both electricity and heat and therefore can
achieve an efficiency of up to 90%, giving energy savings
between 15-40% when compared with the separate
production of electricity from conventional power stations
and of heat from boilers. It is the most efficient way to use
fuel. Cogeneration also helps save energy costs, improves
energy security of supply, and creates jobs. |
 |
The heat produced by cogeneration can be delivered through various mediums, including warm water (e.g., for space heating and hot water systems), steam or hot air (e.g., for commercial and industrial uses). It is also possible to do trigeneration, the production of electricity, heat and cooling (through an absorption chiller) in one single process.
Trigeneration is an attractive option in situations where all three needs exist, such as in production processes with
cooling requirements. Cogeneration schemes are usually sited close to the heat and cooling demand and, ideally, are built to meet this demand as efficiently as possible. Under these conditions more electricity is usually generated than is needed. The surplus electricity can be sold to the electricity grid or supplied to another customer via the distribution system. In recent years cogeneration has become an attractive and practical proposition for a wide range of applications. These include the process industries (pharmaceuticals, paper and board, brewing, ceramics, brick, cement, food, textile, minerals etc.), commercial and public sector buildings (hotels, hospitals, leisure centres, swimming pools, universities, airports, offices, barracks, etc.) and district heating schemes. |
Costs and profitability
A well-designed and operated cogeneration scheme will always provide better energy efficiency than a conventional plant, leading to both energy and cost savings.
Cost savings depend on both the cost of the primary energy fuel and the price of electricity that the scheme avoids. However, although the profitability of a cogeneration project generally results from its cheap electricity, its success depends on using recovered heat productively, so a prime criterion is a suitable heat requirement. As a rough guide, cogeneration is likely to be suitable where there is a fairly constant demand for heat for at least 4,500 hours in the year.
The total investment in a CHP project depends upon the size of the installation and its design and characteristics. Under favourable conditions, payback periods of three to five years can be achieved on most cogeneration installations. Their operating life can reach 20 years.
Key Points
- Cogeneration is the most efficient way of generating electricity, heat and cooling from a given amount of fuel. It
saves between 15-40% of energy when compared with the separate production of electricity and heat.
- Cogeneration helps reduce CO2 emissions significantly. It also reduces investments into electricity transmission
capacity, avoids transmission losses, and ensures security of high quality power supply.
- A number of different fuels and proven, reliable technologies can be used.
- A concurrent need for heat, electricity and possibly cooling indicates suitable sites for cogeneration.
- The initial investment in cogeneration projects can be relatively high but payback periods between 3-5 years
might be expected.
- The payback period and profitability of cogeneration schemes depends crucially on the difference between the
fuel price and the sales price for electricity.
- Global environmental concerns, ongoing liberalisation of many energy markets, and projected energy demand
growth in developing countries are likely to improve market conditions for cogeneration in the near future.
