Abstract:
ERATES (Electricity Rates) is a computer program for
calculating monthly and annual electricity costs for a
facility, building, or system under a variety of
electricity rate schedules. Both kWh usage and kW
demand charges can be included in these costs. Most
typically these calculations will be used to support
engineering-economic studies which assess the
cost-effectiveness of energy conservation measures or
measures to shift electricity use from on-peak to
off-peak time periods. With ERATES a user can create
time-of-use kWh price schedules, block-rate kWh price
schedules, and demand-rate schedules and save these
schedules to a disk file. The user can then compute
monthly and annual electricity costs with ERATES, given
hourly or monthly kWh usage and kW demand data for a
facility, building, or system. ERATES is a menu-driven,
interactive program, designed to be run on an IBM-PC or
compatible microcomputer under DOS version 3.0 or
higher. ERATES block-rate kWh price schedules and
demand-rate schedules can be imported by the NIST BLCC
computer program for use in computing the life-cycle
cost of buildings and building systems. ERATES is not
intended for use by utilities in setting up or
administering electric rate schedules.
