New and Revised Rates for 2023

Residential Time-of-use Demand (R-TOUD)

The Time-of-Use Demand rate has been reconfigured to better align with today's mix of generation sources and the region's changing usage patterns. TOU customers now have greater opportunities to save. The changes include:

• Shortened on-peak periods in both summer and winter months
• A new discount period where energy charges are 30% lower than the standard off-peak rate
• Reduction in on-peak demand cost per kW

The revisions provide customers with the opportunity to shift energy-intensive consumption to times when there is less demand on the electric grid. The much lower energy price offered during new, designated "discount periods" reflect the fact that it is less expensive to provide energy during these hours. Programmable appliances, thermostats, electric vehicle charging timers are among several ways that customers can take advantage of these new hours.

Summer months under the new rate are considered May through September, with non-summer months spanning October through April. Weekend and pre-designated holidays are still considered as off-peak.

In addition to the time changes, the structure for Demand will also be revised and separated into two reduced and unique charges:

• On-Peak Billing Demand will be the highest 15-minute kW demand during On-Peak hours in the current billing month.
• A Max Billing Demand will be the highest 15-minute kW demand during all hours in the current billing month.

	Applicable Days	Summer Hours May – September	Non-Summer Hours October – April
On-Peak Period:	Monday – Friday excluding holidays*	6 p.m. – 9 p.m.	6 a.m. – 9 a.m.
Discount Period:	All days including holidays*	1 a.m. – 6 a.m.	1 a.m. – 3 a.m. 11 a.m. – 4 p.m.
Off-Peak Period:	All days including holidays*	All hours that are not On-Peak or Discount hours

The revised R-TOUD rate schedule with additional detail, including pricing, is available at duke-energy.com/rates.

Residential Time-of-Use with Critical Peak Pricing (R-TOU-CPP)

The new Critical Peak Pricing TOU rate gives residential customers another option that may better suit those with different energy usage patterns. The key differences from TOUD include:

• No demand charges, making the rate easier to understand and manage for many customers
• Critical peak pricing days (~20) that are called over the course of the calendar year, when the on-peak rates are elevated in anticipation of high energy demand
• Notifications a day prior to the critical peak days to provide ample time to plan for shifting energy use

	Applicable Days	Summer Hours May – September	Non-Summer Hours October – April
On-Peak Period:	Monday – Friday excluding holidays*	6 p.m. – 9 p.m.	6 a.m. – 9 a.m.
Discount Period:	All days including holidays*	1 a.m. – 6 a.m.	1 a.m. – 3 a.m. 11 a.m. – 4 p.m.
Off-Peak Period:	All days including holidays*	All hours that are not On-Peak or Discount hours

The new R-TOU-CPP rate schedule with additional detail will be available at duke-energy.com/rates on April 1, 2023.

Additional advantages coming for Residential Customers

In addition to the enhancements to our time-of-use rates*, customers now have a way to help determine the rate most advantageous for their home.

• Our Rate Comparison feature was added with the implementation of our new, modernized billing platform. South Carolina customers with 12 months of service can now utilize the tool by signing in to their online account and going to the Billing & Payments drop-down menu.

Customers with secondary meters on nonresidential rates that meet select criteria may be eligible for a residential rate.

• Stand-alone garages, personal workshops, sheds, etc. may now qualify for residential rate. Depending on the energy usage characteristics, a change could reduce monthly costs for some customers.

The basic Customer Charge, which serves as the general monthly cost to serve customers' connection to the electric grid, remained unchanged as a part of the rate agreement.

• The facilities charge was unaltered to ensure customers with low kWh usage and/or those on fixed incomes are not inequitably burdened with increases to this flat monthly customer fee.

*Customers currently on the Solar time-of-use rate (R-STOU) will not see changes to their current structure.
