In an era where operational efficiency directly correlates with profitability, businesses are constantly seeking ways to optimize expenses. Among various operational costs, electricity consumption stands out due to its substantial impact on the bottom line. Applied Utility Auditors, with its expertise in auditing and reducing utility costs, presents an in-depth guide for businesses to navigate Time-of-Use (TOU) rates and harness them for substantial electricity savings.

What Are Time-of-Use Rates?

Time-of-use rates are a pricing scheme employed by electricity providers that varies the cost of electricity based on the time of day it is consumed. Electricity is generally more expensive during peak demand times, which occur when the majority of consumers and businesses are using it. The idea is to encourage users to shift their electricity usage to off-peak times, thus balancing the demand on the power grid and reducing the need for expensive, polluting peak power plants.

The Structure of TOU Rates


The structure of Time-of-Use (TOU) rates is designed to reflect the varying levels of electricity demand throughout the day, thus encouraging more efficient energy usage by consumers, especially businesses that consume significant amounts of energy. Understanding this structure is crucial for businesses aiming to optimize their operational costs related to energy consumption. Here’s a breakdown of the typical periods defined in TOU rates:

Peak Hours

  • Definition: Peak hours are when the demand for electricity reaches its zenith during the day. During these hours, the electrical grid is under the most stress due to high consumer and industrial activity.
  • Impact on Costs: Electricity prices are highest during peak hours to discourage excessive use and manage the grid’s load effectively.
  • Typical Timing: Although it can vary, this period usually falls into the late afternoon and early evening. For many utilities, peak hours are set from late afternoon (e.g., 4 PM) until the evening (e.g., 9 PM), coinciding with increased household and business activity as people return home and continue using energy-intensive appliances.

Off-Peak Hours

  • Definition: Off-peak hours occur when the demand for electricity is at its lowest, typically when industrial and residential activities are reduced.
  • Impact on Costs: These hours feature the lowest rates, offering an economical option for energy consumption. Businesses can leverage off-peak hours to schedule high-energy tasks at a fraction of the cost.
  • Typical Timing: Most commonly, off-peak hours are during the night to early morning, when commercial activities slow down and most people are asleep.

Shoulder Hours

  • Definition: Shoulder hours are transitional periods between peak and off-peak times. During these hours, electricity demand and prices are moderate.
  • Impact on Costs: The rates during shoulder hours are higher than off-peak but lower than peak times, striking a balance for businesses that may not fully shift operations to off-peak hours.
  • Typical Timing: These hours often occur in the morning and late evening, serving as a buffer before and after peak demand periods.
