Hydro-Québec subsidiary EVLO Energy Storage Inc. recently completed the commissioning of its first battery energy storage project in the United States. Located in Troy, Vermont, this 3 MW/12 MWh system meets a critical need: to optimize the use of renewable energies by improving peak demand management. This project illustrates the growing importance of energy storage solutions in power grid management strategies. Integrating renewable energies into the grid requires technologies capable of compensating for their intermittency. By capturing excess energy and releasing it at peak times, EVLO’s system offers an effective technical response, reducing the strain on existing infrastructure. This management and storage capacity is essential for stabilizing the grid and guaranteeing a reliable power supply.
Advanced technology and local partnership
Troy’s system consists of 16 EVLO 1000 units and four power conversion platforms, all supervised by EVLOGIX energy management software.
This advanced architecture enables fine-tuned management of stored energy, maximizing its use according to grid requirements.
EVLO is responsible for the maintenance and monitoring of this installation under a 20-year contract, in close collaboration with Vermont Electric Cooperative, a key player in the local electricity market . This partnership with Vermont Electric Cooperative is an example of how local collaborations can accelerate the adoption of new technologies in the energy sector.
Operational data collected as part of this project will be shared with the U.S. Department of Energy and Sandia National Laboratories, contributing to a better understanding of the benefits that battery storage can bring on a regional scale.
Challenges for the energy sector
The growing importance of energy storage systems is reflected in EVLO’s expansion into the US market, where demand for flexible, robust solutions continues to grow.
The Troy project is just the first step for EVLO, which plans to roll out similar projects across the United States.
This initiative is part of a wider strategy to strengthen the resilience of power grids to the variability of renewable energies.
The project also highlights the ability of storage systems to support electricity infrastructure in times of energy transition.
By optimizing the use of intermittent energies, these technologies play a central role in the modernization of networks, offering grid operators new options for balancing supply and demand in real time.
