Co-generation concepts

Normally heat demand is leading; power can be delivered into the grid and heat demand is mostly only during winter period

In case of Sotik, power demand is leading

slide 6/11

Typical cogen plants

Complete new stand-alone

Idem, but at waste incineration plant facility

– Basically due to landfill directive

Retrofitting (add biomass) to fossil fuel boiler

Fuel switch: replacing fossil fuel to biomass

Energy efficiency & conservation

Cogen options Kenya and beyond

Sugar industry

Tea industry

Forestry sector (heat for drying)

Coffee industry – Anaerobic digestion of waste water

Fruit sector– For instance, Del Monte produces lots of fruit waste suitable for

anaerobic digestion
