Frequently Asked Questions

The NiteFlex® rate is beneficial for members with an electric vehicle and members who are willing and able to shift their energy consumption. Electric use on the NiteFlex rate is calculated based on three tiers. This tiered pricing also applies on weekends and holidays.

This rate is billed based on usage captured by your AMI meter in a 24-hour period. If we do not receive a valid communication from the meter, our system is designed to estimate usage for that hour using your historical data and usage patterns.

The NiteFlex rate is a 12-month commitment.

Yes. You do not need to have an electric vehicle to be on this rate. To benefit, you can shift your energy use to the Off-Peak (6 a.m. - 1 p.m.) (9 p.m. - 12 a.m.) and Super Off-Peak periods (12 a.m. - 6 a.m.). Shifting your usage during these times allows you to take advantage of the lower billing rate.

We record hourly meter readings. You can also view your hourly usage with our online account management system and the Cobb EMC app. For a detailed look at when you used energy, sign in to your online account and click on My Usage. Next, choose the Usage Explorer tool, and then change the Type of usage to Time of Use to see a breakdown of your hourly energy use during Super Off-Peak, Off-Peak and On-Peak hours.
