What are transmission costs?

In addition to energy supply, capacity and other charges, your energy bill also includes transmission costs. Transmission costs are charges from your local utility for moving a vast amount of electricity from generating power plants to utility substations.

In some utilities, these rates are set and fixed annually by your local utility and are based on your organization’s Network Service Peak Load Contribution (NSPL), which is set annually and is based on your energy usage during peak hours. Network Integrated Transmission Service (NITS) is also factored into your transmission cost, which is specific to your respective utility and may or may not change every year on June 1.

Can I reduce my transmission costs?

You can lower your transmission costs for next year by reducing your usage during high peak times in 2023, which happens only a few hours a year. You can take control of your demand costs with AEP Energy’s complimentary PeakAdvisory® program where you’ll receive notifications during high-demand days alerting you to reduce your energy usage. 1  Learn more about our demand management programs.
