Renewable Heat Incentive A Case Study E.g. Omagh Leisure Centre
400kW Boiler Run 1,700,000 kWh/yr (50% load) Oil Displaced = 160,500 Litres Oil Cost pa = £86,670 (£0.54/l) Wood Chip Cost pa = £51,944 Saving pa = £34,726 Payback without Grant or RHI = 3.5 years
UKRHI = Extra Income from RHI = £44,520 pa or Payback of 1.5 Years
Ni RHI =1,700,000 x 1.3p = £22,100 = Payback of 2.5 years
