Business Time-of-Use Price Plan (E-32)

Watching the clock could help your company maximize its energy savings.

SRP's business Time-of-Use Price Plan (TOU) is an optional price plan where electricity is priced at three different levels depending on the time of day — on-peak, shoulder and off-peak pricing periods.

TOU is designed for businesses with electricity demand ranging from 5 – 1,500 kW that are able to take advantage of the lower prices in the shoulder and off-peak periods. About 85% of the summer hours are either lower-priced off-peak or shoulder hours, offering your company the opportunity to save money.

How it works

The key to saving money on business TOU is to limit usage during the higher-priced on-peak hours and shift to lower-priced off-peak and shoulder hours. You may already be doing some of this, and with some additional adjustments, switching to this price plan could maximize your energy savings.

Plus, off-peak pricing is about one-third the cost of on-peak pricing, making it a significant time frame to save.

In addition to per kilowatt hour charges, demand charges and a service charge apply. They are:

Summer on-peak demand charge: $5.29
Summer peak on-peak demand charge: $6.99
Winter on-peak demand charge: maximum of $4.69
Summer, summer-peak and winter shoulder and off-peak demand charge: $1.05
Monthly service charge: $22.72 plus meter charge (CT/PT $16.88 or demand $6.11)
*All weekend hours are off peak.

Note: The demand charge applies to all kW > 5kW for the maximum demand measured during on-peak hours and shoulder or off-peak hours.

Who can realize the biggest savings?

  • Businesses open:
    • Monday – Friday (8 a.m. – 5 p.m.)
    • Earlier in the summer
    • Later in the winter (after 9 a.m.)
    • Weekends
  • Businesses that can avoid high electricity usage during peak usage hours (Summer 2 – 7 p.m. and Winter 5 – 9 a.m.)

Energy savings tips

  • Install programmable thermostats that automatically adjust temperature settings based on the time of day and day of week.
  • Pre-cool your air-conditioned space on weekdays:
    • Set your thermostat 4° to 5° lower than the normal temperature setting for several hours before TOU peak hours (2 – 7 p.m.) or shoulder hours (11 a.m. – 2 p.m.)
    • During business TOU peak hours (2 – 7 p.m.), readjust your thermostat to its normal setting or, if possible, 2° higher than normal.
  • Perform flexible operations that require significant amounts of electricity during off-peak hours — at night or during the weekend. For example, use timers for equipment such as battery charges and water coolers.
  • Install plug load controllers to control multiple loads like monitors, task lights and fans so inactive equipment can be shut down when the space is unoccupied.
