CHP – Combined Heat & Power

Combined heat and power (CHP) integrates the production of usable heat and power (Electricity), in one single, highly efficient process.

CHP generates electricity whilst also capturing usable heat that is produced in this process. This contrasts with conventional ways of generating electricity where vast amounts of heat are simply wasted. In today’s coal and gas fired power stations, up to two thirds of the overall energy consumed is lost in this way, often seen as a cloud of steam rising from cooling towers.

By recovering most of this otherwise wasted heat, CHP can bring overall energy savings of up to 40 per cent. For an energy intensive development, that can represent a substantial saving, especially when combined with other energy efficiency measures.CHP has been widely recognised as a key measure in helping to reduce harmful emissions of CO2, with some schemes being shown to halve emissions compared with conventional sources of heat and power.

CHP can be incorporated into a tri-generation scheme to provide heating, power and cooling from the same source. Here the excess heat produced is cooled by absorption chillers linked to the CHP system. This produces chilled water for cooling, which is particularly useful for schemes which involve a large level of air conditioning.

For many organisations, CHP is the measure that offers the most significant single opportunity to reduce energy costs and to improve environmental performance with existing users of CHP typically saving around 20% of their energy costs.

The suitability of CHP and tri-generation to provide electrical power, heating and cooling requires a detailed appraisal of many factors, not just heat and electricity requirements. Such is our experience of CHP and tri-generation that Dimension 9 is uniquely positioned to offer a complete turnkey solution from feasibility and design through to financing, supply, installation and commissioning.
