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.

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.
