24 CHP B a s i c s

Unlike the case for existing BCHP installations, Onsite utilizes the MarketPlace
Database (based on Dun and Bradstreet financial listing) from iMarket Inc. to identify
potential segment for future BCHP installations. The potential CHP installation (or the
size of the prime mover) was based on average electrical demand for each sector. Four
groups were selected to represent the sector average electrical demand: (a) 100 to
500 kW, (b) 500 to 1000 kW, (c) 1.0 to 5.0 MW, and (d) more than 5.0 MW. Tables 2-3 to
2-5 show all the potential sectors based on number of establishments and potential
electrical power generation (MW), respectively.
