Table notes: All wattage is of electricity, exclusive of heat generation. Net present values are calculated with a discount rate of 3%. Costs are averages and include: condition-based maintenance by remote monitoring; secondary boiler with a nominal 20-year life; maintenance and servicing. Gas and electricity costs are at current values. CHP operates at 5,000 hours a year. Life-cycle costs with cost savings are based on a comparison with a gas fired boiler system for thermal energy and all electricity bought in. This is a simplified analysis based on constant loads and outputs. A cost analysis based on project-specific information is essential for a best value appraisal.
