Public sector energy consumer

Renewable fuel is at the heart of government energy policy. Changing to woodfuel is a cost-effective option for a range of public sector organisations, particularly in off-gas grid areas, and can help you meet your carbon reduction commitment.

A strategic sourcing strategy has been developed for the supply of renewable heat using biomass wood fuel to end users in the public sector, for further information click here.

Smaller wood fuel heating systems (15 to 500kW)

Automated pellet or wood chip boilers, as well as log boilers, are used successfully in smaller properties to cut fuel bills and carbon emissions. Here are some examples:

Large scale systems (500kW plus)

Larger automated boilers are suitable for schools, hospitals and many other large buildings. They can also run district heating schemes.

Combined heat and power (CHP) plants

Combined heat and power (CHP) can be the single biggest way for you to cut industrial or buildings-related energy costs.  CHP systems convert up to 90% of a fuel's energy into electrical power and useful heat. (Source: Renewable Energy Centre)

Woodfuel can be used to generate both electricity and heat, using the steam produced by burning biomass to drive turbines which generate electricity. Electricity generation alone generally has a low conversion efficiency - around 30-45% whether for fossil fuel or biomass. A significant proportion of the energy available in the fuel is lost as 'low-grade' heat unless it can be used, for example in industrial facilities.

The Scottish Government strongly advocates the deployment of biomass in heat-only or combined heat and power schemes, generally prioritised in off-gas grid areas, at a scale appropriate to make best use of both the available heat, and of local supply. Such siting and scaling of development is vital if we are to stand any chance of meeting our 2020 renewable heat target which depends heavily on biomass.

Combined heat and power (CHP) plants offer the potential to provide local communities with district heating and hot water as well as electricity. They are generally relatively large scale and work well where there is a large heat load, such as UPM Caledonian Paper in Irvine (see Scottish Forest and Timber Technologies website for info).

The Scottish Renewables Forum publishes a regular update on all large-scale renewable energy projects in Scotland and their status.
