Middle Mile Project Progressing, Nearing Launch of Phase II
April 17, 2022

As we work together to build a middle mile fiber network that will interconnect local power companies (LPCs) across the Tennessee Valley, Seven States is excited to announce the Valley-wide project is on track and moving toward the launch of Phase II.

The middle mile network will benefit the interconnected electric grid within the Tennessee Valley by enabling grid modernization while also facilitating deployments of broadband services to unserved and underserved communities. We believe the network will serve as the communications backbone for grid modernization projects such as distribution automation, work management systems, demand management programs, data center mirroring for backup and disaster recovery, and emergency communications to name a few. Additionally, LPCs will be able to purchase support services such as billing, technical support, and 24/7 call centers.

Unanimously approved by the Seven States board of directors in August 2021, the project is progressing in geographic phases, with each phase consisting of four specific steps: high-level design, detailed construction design, construction, and operation.

The local power companies (LPCs) participating in Phase I of the project have been working with Seven States and engineering firm Black & Veatch to develop a high-level design of the network. Over the next several weeks, the 36 of 44 eligible Phase I LPCs – primarily in the eastern part of the region – who signed participation agreements will have the opportunity to review the high-level design and prepare to move forward with detailed construction design.

Concurrently, Seven States is excited to launch Phase II of the project, with Seven States staff poised to begin reaching out to the 53 eligible Phase II LPCs – primarily in the middle part of the region – in the coming weeks to discuss participating in the high-level design process.

If you have questions about the middle mile project, including how to apply for middle mile infrastructure funding in state grant applications , please reach out to Clint Wilson at cwilson@7spc.com.

What Middle Mile Leaders Are Saying:

Clayton Dowell, Director of Engineering, Bristol Tennessee Essential Services: “Much like the decisions we make to build substations with an eye toward the future, it is critically important that we build out a middle mile network before we really need it, to be ready for changes coming to the grid and our customers. I am glad Seven States is taking a proactive approach to interconnect the Valley and know this work will truly pay off down the road.”

Katie Espeseth, Vice President of New Productions, EPB: “Building a middle mile fiber network will prove incredibly valuable by allowing each of our utilities to aggregate the internet needs of the Valley and lower broadband access costs and improve performance and reliability for all of us. It also gives us a unique advantage by giving all LPCs a presence in tier-1 data centers.”

Gary Bolton, President and CEO, Fiber Broadband Association President: “We applaud Seven States’ middle mile fiber network initiative to connect the Tennessee Valley. This project will provide the critical fiber backbone for the 153 LPCs across the region to significantly benefit the communities that they serve.”

Leading Decatur Utilities as General Manager, Ray Hardin strives to ensure their system is prepared for the future with innovative solutions. We asked him to share some of the ways he’s implemented technology in his LPC’s footprint. “Advanced Metering Infrastructure (AMI) has helped us improve efficiency, maintenance, and long-term planning, while providing customers with usage data through the customer portal that enables them to look for ways to reduce their energy consumption and their cost. AMI has also integrated with the Outage Management and GIS Systems to improve outage tracking and reduce system downtime. We’ve also leveraged Demand Voltage Reduction technology to reduce the wholesale cost of electricity to keep customer rates as low as possible. And over several years, we have implemented LED streetlights throughout the City of Decatur, replacing less efficient lighting and saving the city on lighting costs.” Ray knows his LPC is responsible for the present and future of his community’s needs, and he wants his community to know that he strategically evaluates new technology with a long-term vision. “I want our customer to know that through our implementation of AMI, improved communications, Demand Voltage Reduction and other programs, we continue to look for ways to keep our system safe and reliable and provide the best service to our community at the lowest possible rates.” With so much technological advancement in the Valley, Ray encourages fellow leaders to lean on strategic partnerships to help bring about community change and benefits using cost-efficient solutions.  “Don't go it alone! Seven States, TVA and other agencies bring a wealth of resources that can be leveraged to bring innovation to a local community without breaking budgets. For example, Decatur Utilities was able to install two Level 3 Rapid EV Chargers in our community through a partnership with the City of Decatur, TVA, Seven States, and ADECA. It would have been difficult for us to justify the cost of such a project on our own - but through this partnership, the cost was shared while the benefit to our customers and communities is enormous. Seek out those opportunities for shared funding that will benefit your local area and lean on others who have already researched or implement innovative technologies to get their ideas and advice.”

As Chief Information Officer for North Georgia Electric Membership Corporation (NGEMC), Brian Childers knows how crucial innovative partnerships and technology are in preparing for the grid of the future. Brian’s extensive experience has given him a deep understanding of technological diversity and strategic partnerships. We asked him to share some of the ways their team brought innovation to the North Georgia EMC membership, as well as his experience with Seven States as a trusted partner. “The most needed technology developments in our footprint focused on improving reliability, security, and member service. Upgrades to SCADA systems enhanced grid monitoring and automation, allowing faster outage detection and restoration. Cybersecurity improvements were critical to safeguarding member data and ensuring uninterrupted service. Mobile workforce tools streamlined field operations, enabling quicker response times to outages and service requests. Additionally, the installation of distribution system sectionalizing equipment, supported by fiber expansion, improved fault isolation and communication across the network, significantly reducing outage durations and strengthening overall system reliability for our members. Seven States has helped our LPC support innovation by providing access to emerging technologies and collaborative opportunities. They also share best practices that keep us aligned with industry advancements and prepared for future member needs.” Brian always considers how their members view NGEMC’s investments in innovation. “I want our members to know that our role in innovation is centered on improving their quality of life and ensuring reliable, secure, and efficient service. We invest in technologies like advanced grid automation, fiber-supported communication systems, and modern outage management tools to deliver faster restoration, better reliability, and enhanced security. Every innovation we pursue is designed to strengthen our community—whether by reducing outage times, enabling smarter energy solutions, or supporting future connectivity needs. Our commitment is to keep members at the heart of every technology decision we make.”  Brian has learned that being plugged into your community and knowing their needs is fundamental to being an innovative leader. He offered this advice to others who might have questions about how to start bringing innovation to their LPC. “NGEMC’s territory includes communities served by multiple power providers, which limits large-scale community investments. Because of this, innovation should focus on projects that deliver clear, measurable benefits to members. Prioritize technologies that improve reliability while helping keep rates affordable. Stay informed on emerging trends like energy storage and flexible rate options while communicating openly with members to encourage adoption. Above all, maintain a long-term vision that balances innovation with financial responsibility, ensuring every investment strengthens member trust and delivers lasting value.”
