Gas Engine CHP• Sizes from 100 kWe – 4 MWeSizes from 100 kWe 4 MWe• Heat from engine cooling water (≈ 90°C) + heat from hot exhaust gases (≈ 400°C) harnessedharnessed• Heat/Power Ratio ≈ 1.1/1
Uses for heat:• Water @ up to 90°C for space heating or
hot water demandhot water demand• Steam for Industrial Process• Exhaust gas CO2 generation• Absorption Chilling• Low temperature demand, i.e. for under-
floor heating, swimming pool etc.

Biomass CHPBiomass CHP is the use of a biomass fuel to simultaneously generate both
electricity and useful heat in a renewable processelectricity and useful heat in a renewable process
2010 CES Energy Group Overview
Biomass CHPBiomass CHP• CES Energy offers biomass CHP solutions for large
ind t i l iteindustrial sites
• Biomass fuel can be woodchip from forestry or energy crops (miscanthus willow etc)crops (miscanthus, willow etc)
• System electrical outputs from 500 kWe – 5 MWe
• Full heat recovery giving hot water/steam
• Heat:Power ratio > 3:1
• CES Energy has established relationships with industry leading suppliers worldwide
• Biomass CHP solutions offer ‘zero carbon’ alternative to conventional fuels (gas/oil etc)
2010 CES Energy Group Overview
h TWhat is Tri-generation?• Tri-generation is the simultaneous generation of the 3 primary energy
requirements for a building from a single fuel input.
• Electricity• Heat• Cooling
• This plant consists of these primary components:
l• CHP plant• Absorption chiller• Distribution system
l• Control system• Heat dissipation equipment
