PowerSecure, a subsidiary of Southern Company, is teaming up with Powder River Energy Corporation (PRECorp) and the National Rural Telecommunications Cooperative (NRTC) to build a utility-scale battery and solar hub that could save the rural cooperative $1 million annually. The project, announced on April 17, 2026, from Durham, North Carolina, will be centered in Moorcroft, Wyoming. By blending solar generation with massive battery storage, the initiative aims to stop the bleeding of high wholesale power costs and stabilize a grid currently strained by industrial expansion in the Powder River Basin.
Here's the thing: rural grids aren't built for the kind of sudden industrial spikes Wyoming is seeing. When a new facility opens or load expansion hits, the local utility often has to buy expensive "peak" power from the wholesale market. It's a costly cycle that usually ends up on the members' monthly bills. This project is a direct attempt to break that cycle.
The heavy lifting on the design and delivery falls to PowerSecure. Jim Smith, President of PowerSecure, noted that the goal is about delivering real value to the cooperative's members. He pointed out that the combination of battery storage and solar allows the utility to manage peak demand and control costs while keeping the door open for future growth. Turns out, this isn't just about "going green"—it's a pragmatic business move to ensure the lights stay on without breaking the bank.
- Battery Capacity: 5 MW system with 21.6 megawatt-hours (MWh) of storage.
- Solar Generation: 1.25 megawatt direct current (MWdc) ground-mounted arrays.
- Financial Impact: Estimated reduction of up to $1 million in annual wholesale power costs.
- Timeline: Two-year development window, operational by 2027.
- Primary Driver: Industrial growth in the Powder River Basin region.
Technical Breakdown of the Moorcroft Installation
The project isn't just a few panels in a field. It's a sophisticated integrated energy solution. The 5 MW battery energy storage system (BESS) with a 21.6 MWh capacity acts like a giant reservoir. It can soak up excess energy when demand is low or when the solar panels are cranking out peak power, then discharge that energy exactly when the grid is most stressed. This is what engineers call "peak shaving."
Adding 1.25 MWdc of ground-mounted solar into the mix means the system isn't just storing power—it's creating it. This hybrid approach gives PRECorp a level of operational flexibility they've never had. Instead of relying solely on the external grid, they can pivot to their own stored reserves during those expensive peak hours. (It's essentially like having a massive, sustainable backup generator that pays for itself over time.)
The construction and commissioning phase will take roughly two years. Given the April 2026 start date, the system is targeted to be fully operational in 2027. The process involves not just the physical installation of the batteries and panels, but the complex integration of software that tells the system when to store and when to release power based on real-time grid needs.
The Ripple Effect on Rural Energy Reliability
Why does this matter for the average resident of Moorcroft? Beyond the potential for lower bills, there's the issue of resilience. Wyoming weather is famously unpredictable, and rural lines are often the first to go during extreme storms. The new system provides critical backup power capacity. When the main line fails, these batteries can step in, potentially preventing wide-scale outages.
The collaboration between PowerSecure, PRECorp, and the NRTC also highlights a growing trend in the energy sector: the "distributed energy resource" (DER) model. Instead of relying on one massive power plant hundreds of miles away, utilities are moving toward smaller, localized hubs of generation and storage. This makes the entire network more robust.
Interestingly, the industrial growth in the Powder River Basin—which created the problem—is also the catalyst for the solution. The region's expansion has put a strain on the old infrastructure, forcing utilities to innovate or face frequent brownouts and skyrocketing costs. By addressing these grid-level challenges now, PRECorp is effectively "future-proofing" the region's economy.
Strategic Partnerships and the Road Ahead
This venture is a strategic win for Southern Company (NYSE: SO) through its subsidiary. By proving that these systems work in the rugged environment of rural Wyoming, PowerSecure is positioning itself as the go-to contractor for other rural cooperatives across the U.S. facing similar load expansion issues.
Looking forward, the success of the Moorcroft project will likely serve as a blueprint. If PRECorp can actually hit that $1 million annual savings mark, expect a wave of similar projects to pop up across the Midwest and Mountain West. The details of the actual installation are still unfolding, but the blueprint is clear: combine renewables with high-capacity storage to decouple rural utilities from the volatility of the wholesale power market.
Frequently Asked Questions
How will this project actually lower costs for PRECorp members?
The system reduces costs by "peak shaving." By using stored battery power during times of highest demand, PRECorp avoids buying expensive wholesale electricity from the market. These savings, estimated at up to $1 million annually, can then be passed down to the members in the form of more stable electricity rates.
What is the specific capacity of the battery and solar installation?
The project features a 5 MW battery energy storage system with a total capacity of 21.6 megawatt-hours (MWh). This is paired with 1.25 MWdc of ground-mounted solar panels, creating a hybrid system that both generates and stores energy for maximum grid flexibility.
When will the energy system be fully operational in Wyoming?
The project has a two-year development timeline encompassing construction, installation, and commissioning. Having been announced in April 2026, the integrated system is targeted to be fully operational and delivering power to the grid in 2027.
Why is this project necessary for the Powder River Basin region?
The region has experienced significant industrial growth and rural load expansion, which has put immense pressure on the existing electrical grid. This has led to higher peak demand challenges, making a localized storage and generation solution essential to maintain reliability and control costs.
Who are the main organizations collaborating on this project?
The primary partnership consists of PowerSecure (a Southern Company subsidiary) acting as the lead contractor, the Powder River Energy Corporation (PRECorp) as the operating utility, and the National Rural Telecommunications Cooperative (NRTC) as a collaborative partner.
