Savings
Savings
derived from the use of GTIs Bi-Fuel System are the result
of either:
1) The differential between
the cost per kWh charged by the utility and the cost per kWh to produce
power with a Bi-Fuel generator or,
2) In the case of existing
diesel prime power operations, the differential in the cost of diesel
fuel and natural gas.
Utility Supplied Power:
Due to the premium prices
which utility companies usually charge for on-peak electricity, it
is often most viable to operate the Bi-Fuel generator as a peak-shaver,
whereby power is produced on-site only during those hours when electricity
is at its highest price from the utility. In order to determine
the cost of producing power with a Bi-Fuel generator, several factors
must be considered including:
Cost of natural gas
Cost of diesel fuel
Cost of maintenance
program for generator
Cost of future engine
overhauls
A
typical example of Bi-Fuel savings for a 500 kW peak-shaving
project would look as follows:
