Waterbury, VT - October 15, 2025 - NOMAD Transportable Power Systems and DSO Electric Cooperative today announced the successful results of a pilot project that used Mobile Battery Energy Storage Systems (BESS) to combat high-cost summer peak demand charges. The deployment of two NOMAD Traveler units is projected to save the cooperative about $150,000 this season by reducing demand charges from its energy supplier, Kansas Electric Power Cooperative (KEPCo). The pilot's definitive success prompted DSO to purchase two of the units for ongoing seasonal use.
For rural electric cooperatives like DSO, brief spikes in energy consumption can lead to substantial monthly bills based on the highest 15-to-60-minute interval of usage. The NOMAD mobile ESS provided a flexible, rapidly deployable solution to "shave the peak" by charging the batteries during off-peak hours and discharging them during these critical high-demand periods.
Derrick Rutherford, Communications Manager for DSO Electric Cooperative, explained the financial pressure driving the project. "Our electric grid is designed with the capacity to provide service above any peak demand our members may require at any given time. DSO pays for that peak demand through the bill DSO receives from Kansas Electric Power Cooperative (KEPCo), its energy supplier. That is why it is so important for DSO and its members to try and reduce usage during peak billing times."
The two NOMAD Traveler 1MW/2MWh units were seamlessly integrated into DSO's distribution network with a setup time of less than one day and no additional permitting required. The pilot's success demonstrates the compelling economic case for NOMAD's seasonal leasing model, which allows utilities to avoid major capital expenditures for a seasonal issue.
Pilot Project Highlights:
Significant Economic Impact: Projected savings of $150,000 in demand charge reduction on an all-in lease cost of approximately $120,000 for the season.
Rapid ROI: A positive return on investment within a single season, with a projected 20% margin.
Operational Flexibility: The units were deployed only for the peak season and can be easily relocated to other facilities as grid needs change.
Proven Strategy: The project successfully validated the use of mobile BESS for peak shaving in a rural cooperative setting.
This collaboration with DSO Electric proves that our mobile energy storage solutions offer an immediate and financially sound answer to the peak demand challenges faced by cooperatives," said Chris McKay, COO of NOMAD Power. "We are empowering utilities to manage their costs and enhance grid reliability without being locked into permanent infrastructure. DSO's subsequent purchase of 2 units is a clear validation of our technology's real-world value.
