Large Commercial and Industrial Business

You are considered a large commercial or industrial business customer if you have used more than 200 kW per month for 3 consecutive months in the last 12 months.

You can find the monthly kW usage on your bill next to your Demand Charge. If you don’t have a Demand Charge, then you are under 200 kW per month.

Transition Schedule

  • May 2010

    Beginning May 2010, Large Commercial and Industrial Business customers transitioned to Peak Day Pricing. Customers have the ability to opt out of Peak Day Pricing by choosing an alternative time-of-use rate plan.

Peak Day Pricing

Peak Day Pricing is an optional program where businesses agree to reduce energy usage on a few days throughout the year when demand is highest—between 9 and 15 "event days" annually. A higher rate is charged during peak times on event days.

In return, between May 1 and October 31, businesses receive credits for their electricity use outside of Peak Day Pricing event hours.

Learn more about Peak Day Pricing.

Customers who participate in Direct Access or net metering are not eligible for Peak Day Pricing. Additional exceptions apply.

Customers are eligible to participate in Peak Day Pricing and a qualifying Demand Response program. Download (PDF) the Dual Participation fact sheet to learn more.

Time-of-Use Rates

Large Commercial and Industrial Business customers have the ability to opt out of Peak Day Pricing by choosing an alternative time-of-use rate plan.

Instead of a single flat rate for energy use, time-of-use rates are higher when electric demand is higher. Higher demand periods are typically weekdays May through October, noon to 6 p.m. In return, time-of-use rates are lower at all other times.
