Community
Communities• Rural & urban• Large & small• Wealthy & poor• New build &
retrofit
Communities• Country estates –
business is brisk
Supermarket – energy hub?
Community drivers• Save money!• Make money!!• Energy security• Reduce ‘carbon footprint’• Environment, quality of life
benefits• Educational benefits• Business diversification• Retain and also create jobs• Part of market placement.......
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 ......

Houses
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?
Hybrid Energy SolutionsAre Best
UK Insolation
Hybrid solutions
• Wood fuel works well with solar thermal and solar PV for example
30 years experience ....well proven, low risk
Technology
Hybrid solutions
• Wood fuel provides all hot water and space heating in winter
• A combination of wood fuel and solar thermal work in the spring and autumn
• Solar thermal provides all hot water in the summer
Technology choice
Technology choice
Meeting Energy Needs• PV generates 60 - 70%
electricity needs (3.06kWp) THERMAL STORE• Solar thermal generates a
third of hot water needed (5.1 kWth)
• Multifuel stove/ back boiler generates remaining space heat needs to a maximum of 19.2kWth
• 4kWe immersion heaters
Feed in Tariff• Introduced 1st April 2010• Marketed as ‘Green Cash Back’ • PV, AD, Hydro, Wind, MicroCHP pilot• Paid on all electrcity generated• Up to 41.3p/ kWh for PV (buy in 13p/ kWh)• A further 3p/ kWh for units exported• Halved the payback for PV• 4.8% increase as from April 2011• Changes anticipated prior to April 2012 for
systems >50kWp (19th July?)
FIT - Massive Impact!
• 21,000 installations registered, of which:• 19,854 PV• 1,132 wind• 178 hydro• 36 micro CHP• 2 Anaerobic digestion
Renewable Heat Incentive
• First fiscal assistance for renewable heat
• Recognises the importance• Biomass, ASHP, GSHP, solar thermal• Will commence Summer 2011?• Up to 9p/ kWhth for small biomass• Up to 18p/ kWhth for solar
Community Energy Solutions
Case Study‘Community Energy’
Small Scale District Energy Scheme

Village Hall Church
Small Scale District Energy Scheme
Full Scheme
Financial …..ESCo’s?
A ComESCo?• Establish a company to manage
community energy assets• Draw in grants, source financing needed• Local share issue and ‘buy in’• Operate and maintain• Match fossil price per kWth• Partner with local wood fuel suppliers and
SRC growers with extended supply contract
