2. Good Practice Proposal
Innovative Financing and Operation
of Small Scale Biomass Energy
Supply and Energy Efficiency
Upgrades in Public Facilities
3. Potential
• Biomass presents strong potential to significantly reduce the heating
bill for public body facilities as a whole and to bring the heating and
hot water portion of each site’s energy consumption to zero carbon
emissions. To date, financial restrictions on public bodies in the
MWRA has significantly deterred uptake of Renewable Energy
Systems (RES), including Biomass. The innovative financial model
developed by the Tipperary Energy Agency offers public bodies the
opportunity to reduce their annual energy costs along with their
carbon footprint, without the need for significant capital investment.
The benefits of this risk removal model for the authority have been
successfully demonstrated in four case studies within the region to
date (Nenagh Leisure Centre, Thurles Leisure Centre, LIT Tipperary
and Coolbawn Water Treatment Facility).
4. Problems Addressed
• Capital costs of investment
• Project risk factors
• Lack of demonstration of successfully
implemented, alternative financial models
• Lack of market demand for energy service
companies
• Public private partnerships are rare in the
energy supply market
5. Key Aspects
• Energy Services Contract (ESCO)
• Three to five year heat supply, operate and maintain
contract
• Alternative model is where the local authority can sign a
long term (5 to 15yr) energy supply contract
• Risk analysis scenarios
• Energy efficiency measures
• Liability for and maintenance of physical assets
• Liability for the use of backup fuels
• Liability and impact of energy demand change
10. Project Evaluation
• Coolbawn Water Treatment Plant
Savings over 7 yrs. of ESCO €20,300

Combined effect of risks
•The cost inflation rate of fuel
reduces below the
conservative 4% value.
•The oil price for 2013 is
reduced by 10c/litre.
•The energy saved by the
ESCO is reduced by 20%.
•The energy consumed in the
Pre-Filtration Building is
increased by 15%
