Commercial Storage/Off-Peak Heating
Controlled Access-Storage Heating
The Storage/Off-peak rate is designed around the ability to store
energy for space heating and water heating and cooling. . During
off-peak hours from 11 p.m. to 7 a.m., when the cost of electricity
and system demand is less, special storage equipment turns on and
stores the energy needed for the balance of the day.
A storage system
can consist of thermal storage room units, a central storage furnace,
a central hot water system or slab heat. Larger combinations may
be necessary, depending on hot water demand. Electricity to energize
the heating equipment is on only between 11 p.m. and 7 a.m. This
system is also known as controlled access or "ETS" (electric thermal storage).
