Why do we need it?UEA Energy demand

• HEAT for space heating, domestic hot water,
  Sportspark pool heating, and temperature
  controlled research environments
• 42,000,000 kWh per annum
• ELECTRICITY for lighting, office equipment,
  cooking, research equipment, etc
• 32,000,000 kWh per annum
• COOLING due to equipment or Solar heat gain

Proposed BIOMASS

• Increasing need
• Extra 1.4MWe ,2MWh
• Increasing costs
• Under 7 year payback
• Future fuel availability
• Local wood fuel
• Environmental issues, Cred, Environmental school
• Reduces Carbon Emissions of UEA by over 35

16
BIOMASS Project as of June 2008

• 8.5 million (1m DEFRA GRANT)
• Reduction in Utility costs 1.2m
• Renewable Obligation Certificates 0.9m
• Export power 0.3 m
• Cost of wood approx. 0.4m
• Cost of maintenance 0.3m

UEA Carbon Emissions

• 1990-2006
• 5870-14,047 students (239 INCREASE)
• 138,-207,000 sq.m (49 INCREASE)
• 19,420-21,652 T of CO2(10 INCREASE)
• 1990-2006
• 3308-1541 kg/student (53 reduction)
• 140-104 Kg/CO2/sq.m (25reduction)
• 2009 Assuming Biomass
• 24.5 reduction in CO2 over 1990 levels despite
  increases in students and building area
