Happy Right-of-Way Worker Appreciation Week!

This week, we’re recognizing the hardworking crews who help keep our rights-of-way clear, safe, and accessible. Their work plays a vital role in maintaining reliable electric service for our members by reducing outage risks, improving safety, and ensuring our line crews can reach equipment when needed.

Thank you to all of our right-of-way workers, both pictured and not pictured, for the important work you do behind the scenes to help keep the lights on.

Spring projects are in full swing, and a few colored flags can tell you a lot about what’s underground.

Before you dig, plant, build, trench or start any outdoor project, call 811 so underground utilities can be marked safely. Once the marks are there, respect the flags and give crews plenty of room to work safely.

Our linemen recently completed pole top rescue training, practicing the critical skills needed to safely and quickly respond if a fellow crew member is injured while working on our lines.

It’s the kind of training we hope they never have to use, but it is an essential part of keeping our crews prepared, protected, and ready for any situation.

Thank you to our linemen for the work they put in every day to serve our members safely.

May 20 marks the anniversary of the Rural Electrification Act, the moment that changed rural America forever.

Around southern Illinois, families still talk about “the night the lights came on.” For many, it was the first time homes, barns, and communities were powered—opening the door to safer, more productive, and more connected lives.

That progress didn’t happen by accident. It was built by local people coming together to form electric cooperatives, laying the foundation for what we now know as SouthEastern Illinois Electric Cooperative.

Nearly 90 years later, we’re still carrying that mission forward, serving our members and keeping the lights on, just like it all began.

Did you catch the May President’s Column in Illinois Country Living?

In this month’s article our president, Dustin Tripp, highlights our new Peak Power Rewards program, which gives SEIEC members the opportunity to earn bill credits by reducing electricity use during short peak demand events.

Participation is voluntary, and members choose how they want to take part. Even small changes, like adjusting the thermostat a few degrees, delaying appliance use, or grilling instead of using the oven, can help lower demand and earn credits on your bill.

Peak events are likely to begin during the summer months, so now is a great time to enroll and be ready.
