DERMS Solution for Appalachian Electric Cooperative
June 20, 2019

For all that Appalachian EC, New Market, Tenn., has going for it, the cooperative is saddled with a significant deficiency.

“We have one of the worst load factors in the Valley,” said Greg Williams, Appalachian EC’s longtime general manager and a former TVPPA chairman. “Our No. 1 goal is to impact our load factor.”

Enter Seven States Power Corp., which not only offered Williams a way to manage his load control, but to do it with relative simplicity – thanks to DERMS (Distributed Energy Resource Management Systems), a software product made by Seven States partner OATI.

“DERMS offers us the opportunity to centralize all those [load-control] functions and manage those effectively,” Williams said. “And, secondarily, the fact that it’s a Seven States solution makes it an ideal solution.”

It isn’t that Appalachian EC can’t manage its load issues on its own – the trick, Williams said, is to do it as effectively as possible.

“Trying to manage all those different things – water heaters, voltage control, all of it – in all those different silos can be challenging,” Williams said. “We have SCADA, AMI and different software tools, but no way of truly focusing our efforts on energy management.

“DERMS lets us pull all those together into one platform, and it opens the door for other potential projects – battery storage comes to mind,” Williams said. “And we weren’t actually looking at doing this – Seven States brought it to our attention and really opened our eyes as to the possibilities. Seven States brought a solution that we didn’t even know existed.”

Williams said that while DERMS is still in the pencil-and-paper stage at Appalachian EC, he’s already eyeing some near-term goals.

“I’d love to be able to start with voltage control by the end of 2019, then look at adding a demand-response program for our commercial and industrial customers by next spring,” he said. “Those are two things I think we could do fairly quickly.”

Electric Board of Guntersville, City of Guntersville, and Seven States Power Corporation Unveil Battery Storage and EV Charging at Guntersville Senior Center

By Jessica Bradshaw • October 2, 2026
GUNTERSVILLE, AL — October 2, 2026 — Electric Board of Guntersville and the City of Guntersville, in partnership with Seven States Power Corporation, today celebrated the ribbon cutting and official unveiling of a new battery energy storage system (BESS) and two electric vehicle (EV) charging ports at the Guntersville Senior Center. The project represents an investment in reliability, emergency preparedness and modern energy infrastructure for the Guntersville community. The battery system is designed to provide backup power to the Senior Center during outages, helping the facility continue serving residents when reliable electricity is needed most. The addition of battery storage will also enable the Senior Center to meet critical emergency preparedness requirements for designation as a FEMA shelter, strengthening its ability to serve residents during severe weather and other emergency events. “This project is about putting innovative technology to work in a way that directly benefits the people we serve,” said Jason Kirkland, General Manager of Electric Board of Guntersville. “By adding battery storage and EV charging at the Senior Center, we are investing in infrastructure that supports reliability today while preparing our community for the needs of tomorrow.” The City of Guntersville partnered with Electric Board of Guntersville and Seven States to bring a 261kWh battery energy storage system (BESS) to the Senior Center, supporting an investment that strengthens the facility’s role as a vital community resource and enhances its ability to serve residents during emergencies. The battery unit will store energy during off-peak hours and be used as necessary to supply power to the facility during an outage or to deploy power for up to 2 hours back onto the Guntersville electric grid. The two new EV charging ports complement the battery installation by expanding access to charging infrastructure for residents and visitors. Together, the technologies demonstrate how community-scale energy projects can provide practical benefits while helping local power companies modernize infrastructure. “What makes this project special is its purpose. This battery is more than a piece of energy infrastructure, it provides another tool to help Guntersville care for its residents and keep an important community facility powered when it matters most,” said Guntersville Mayor Leigh Dollar. “Seven States was created to help local power companies turn opportunities like this into projects that deliver meaningful benefits in their communities,” said Betsey Kirk McCall, President & CEO of Seven States Power Corporation. The Guntersville project is part of Seven States’ broader work with local power companies across the Tennessee Valley to develop and finance energy infrastructure tailored to local needs.

Seven States Power Corporation Issues RFP for 220MW Energy Express Battery Storage Project

By Jessica Bradshaw • September 2, 2026
CHATTANOOGA, Tenn. — September 02, 2026 — Seven States Power Corporation has issued a Request for Proposals (RFP) seeking a qualified provider to supply battery energy storage systems and a 20-year long-term service agreement for the Energy Express Project, a 220-megawatt battery storage initiative being developed in partnership with Memphis Light, Gas and Water (MLGW), Nashville Electric Service (NES), and BrightRidge. The competitive procurement represents another major milestone as Seven States advances one of the Tennessee Valley’s most significant investments in distribution-connected battery storage. The Energy Express Project will deploy battery energy storage across multiple locations in west, middle, and east Tennessee, including 100MW in partnership with MLGW, 100MW with NES, and 20MW with BrightRidge. Seven States will own and operate the assets, which will be interconnected with the local utilities’ distribution systems and designed to charge during lower-demand periods and discharge when demand is highest. The systems will provide the utility partners with greater operational flexibility while helping manage peak demand, strengthen reliability, and make more efficient use of existing grid infrastructure. “Moving into procurement marks an important step toward delivering these assets for our local power company partners and the communities they serve,” said Betsey Kirk McCall, President and CEO of Seven States Power Corporation. “Through Energy Express, we are combining federal financing, local partnerships and innovative energy technology to make a long-term investment in the Tennessee Valley’s electric infrastructure. This RFP will help us identify a partner capable not only of delivering the technology, but of supporting its performance and reliability throughout the life of the project.” The Energy Express Project is backed by Seven States’ $439 million award through the U.S. Department of Agriculture’s Rural Utilities Service New Empowering Rural America (New ERA) program. Construction is expected to begin in 2027, with the battery assets targeted for commissioning in late 2028.
