Understanding Energy Alerts
At times, the regional electric grid experiences periods of unusually high electricity demand. Summer heatwaves, extreme cold temperatures or equipment failure may cause high-demand periods. During these events, grid operators may issue Energy Emergency Alerts (EEAs) and request conservation measures to help maintain reliability. North Carolina’s regional grid operator is Duke Energy.
For clarity, NRLP refers to Level 1 and Level 2 EEAs as Energy Alerts or High Demand Periods. These alerts are typically conservation-focused and do not affect electric service.
Level 3 alerts represent emergency grid conditions and may require additional actions to protect system reliability, such as controlled outages.

Understanding EEA Levels
Most energy alerts will result in customers being asked to conserve energy voluntarily — even while the utility takes different steps on its end, depending on the alert level. Alert levels are based on real-time grid conditions and do not always progress sequentially.
Depending on system conditions, an alert may begin as a Warning or at any given numbered level. Likewise, conditions may improve or worsen quickly, causing alerts to move between levels without following a numerical sequence. It’s important to remain patient as the utility issues messages as directed by the regional grid operator and Balancing Authority.
Warning Alert
A Warning Alert is issued to utilities about potential high energy demand in the near future. No action is needed and customers will not be notified at this level. This alert is given for awareness only to utilities and provides better communication among providers.
Level 1: High Demand Period
Electricity demand across the regional grid is elevated. Customers are encouraged to voluntarily conserve energy during designated hours to help support grid reliability. The utility also takes steps to reduce load. No interruption to service is expected at this level.
Level 2: Critical High Demand
Electricity demand is approaching levels that require additional conservation efforts. Customers are encouraged to reduce nonessential electricity use during the alert period. The utility implements additional load reduction.
Level 3: Energy Emergency Alert
Available electricity resources are critically limited. Additional emergency measures may be required, including the possibility of controlled outages. NRLP will communicate with customers through all available channels.
How NRLP Communicates During Energy Alerts & Periods of High Demand
NRLP is committed to keeping customers informed during these events. We will communicate when alerts are issued and when they are lifted.
For Level 1 and Level 2 alerts, NRLP will provide updates and conservation guidance through our website and social media channels.
If a Level 3 alert is issued or conditions have the potential to impact electric service, NRLP will expand communications to include email notifications, website updates, social media posts and other available communication channels.
Customers are encouraged to participate in voluntary conservation efforts during periods of high and critically high demand. When many customers take small actions to reduce electricity use, it can help support regional grid reliability and reduce the need for additional emergency measures.
Energy Conservation Tips
North Carolinians working together can help reduce energy use and protect the grid.
Simple steps to take in the summer:
- Turn your thermostat up a few degrees
- Turn lights off in rooms not in use
- Delay using large appliances and charging EVs until after peak hours
Remember, peak hours for summer are from 4 to 8 p.m.
