Biomass CHP (Combined Heat & Power) 
 
Heat and electricity are produced from sustainable biomass wood chips through a process called gasification. The wood chips are converted into a gas (Syngas), which fuels a generator to produce electricity. The combustion of this gas creates heat, which is transferred into water that can be used at your business for heating and hot water. Most renewable technologies take advantage of one or two of the tariffs to help pay back the cost on the system. Biomass CHP can take advantage of 4 tariffs! 
 
What is Biomass CHP? 
 
CHP stands for Combined Heat & Power, in short, you burn wood chip which creates hot water and electricity. 
 
How does it work? 
 
A CHP unit is broken down into two different sections, the ‘Gasifier’ and the ‘Engine’. The Gasifier burns through wood chip and creates biogas. It also creates a small amount of hot water during the burning process and this equates to a Biomass Tariff. Once the biogas has been produced it passes through a number of lters to ‘clean’ the gas and then it passes to the ‘Engine’, here the engine runs on the Biogas 
and produces electricity and also a large proportion of the hot water. 
 
How do I get paid? 
 
There are 5 possible income streams from a Biomass CHP system: 4 tariffs: ROC, Biomass RHI, Biogas RHI, Export Power Purchase Agreement and On-site Savings. 
 
What are the site requirements? 
 
Three phase power is a must and ideally a transformer would be located near to the Biomass CHP location so as to minimise cost. There needs to be a large heat load on the site in order to use the excess heat, examples of this could be wood chip drying, grain drying, greenhouses or high usage of hot water and/or heating. 
 
How much wood chip does it need? 
 
Each unit will use approximately 340 tonnes of dried woodchip per annum for 7,500 running hours. This cost is included in Calibrate’s cash flow analysis. 
 
How labour intensive is the system? 
 
The CHP system has to be designed to run consistently throughout the whole year in order to maximise the tariffs and income. As such the system needs to be monitored constantly, labour will be involved to continuously feed the system with wood chip. This can be reduced with large wood chip stores and automated feeding. Calibrate provide a ‘Hands Off’ solution incorporating the day to day operation of the system with an extended warranty package, remote monitoring and tariff management.
