Community Energy• Consider total energy needs (electricity and heat) and
pattern of usage• Are there efficiency savings to be made?• How best to satisfy this from a range of renewable
energy options available (hydro, wind, solar, heat pumps, AD …..)
• Consider existing arrangements and retention as ‘back-up’
• Size wood boiler accordingly, buffer tank included, access etc
• Perhaps multiple units used• Local fuel supply including ......

Prerequisites• Champions• Focus, a school, village
hall, community building• Co-located heat sinks for
a core scheme• Off gas is helpful• Economics ….. RHI to the
rescue?
