Off-Peak Electric Heating and Cooling
Off-peak
electric heating/cooling systems under
load
management make heating with electricity competitive with other
fossil fuels. PPCS has two programs available – storage heating and
dual-fuel heating. Both may qualify for lower electric rates.

Off-Peak Storage Heating
Storage rate (winter): 5.5¢/kWh
Storage rate (summer): 7.6¢/kWh
Electric storage heating systems convert electricity into heat
during off-peak hours when the demand for electricity is low.
The stored heat is distributed later, as needed, to heat your
home 24 hours a day. These systems qualify for lower electric
rates and may be eligible for rebates. There are two basic
systems: |
 |
-
Electric radiant floor heat
is supplemental heating that works from the ground up, using
one of two systems – electric cable or mats, or hydronic
tubing and mini boiler.
-
Electric thermal storage (ETS) room
units/central heating systems
are 100 percent efficient. Electricity is converted to heat
during
low-cost off-peak hours and stored
in specially designed, high-density
brick.
ETS systems charge for 10 hours each day during the off-peak
period and provide enough heat from storage to keep your
room or entire house comfortable all day.

installation of the current transformer (CT) sub-metering of
off-peak electric systems is illustrated in our

Off-Peak Dual-Fuel Heating
Dual-fuel rate (winter): 6.75¢/kWh
Dual-fuel rate (summer): 8.75¢/kWh
Dual-fuel
heating uses two separate heating sources, electricity and
another fuel source – propane, natural gas or oil – for a
backup. The heating system will automatically use the backup
source when the electricity is interrupted through our load
management system. Electric heat can be shut off up to 12 hours
in any 24-hour period during the heating season. |

Dual-fuel heating options include electric plenum, baseboard and
cove heaters, and hyrdronic electric boilers.

Heat Pumps
Dual-fuel rate (winter): 6.75¢/kWh
Dual-fuel rate (summer): 8.75¢/kWh
Heat
pumps help you capture naturally occurring heat from the air or
the earth and move it where you want: indoors
in winter, outdoors in summer. The
technology is one of the most efficient for heating and cooling.
Heat
pumps
under
load
management
may qualify for off-peak dual-fuel electric rates and rebates.
Since heat pumps also function as your home’s central cooling
system,
cycling is required. |

-
Air-source heat pumps
transfer heat between your house and the outside air.
During the summer months, when used as an air conditioner,
the unit
cools your home by transferring heat from indoors
to the outside.
In the heating mode,
the unit
can efficiently meet your home’s heating needs.
Most heat pumps have a balance point when supplemental heat
kicks in to maintain the thermostat setting when the
temperatures dip below freezing.
-
Ground-source heat pumps
(or geothermal heat pumps)
take advantage of consistent temperatures below ground, all
year round.
Instead of moving heat to and from outdoor air, a
ground-source heat pump uses the earth. It is a complete
heating and cooling system operating at up to 300 percent
efficiency.
