Lightshift Energy, a leading company in the development, ownership, and operation of energy storage projects, is set to build Vermont’s largest battery energy storage facility at the GlobalFoundries semiconductor manufacturing site in Essex Junction. With all necessary permits and contracts in place, construction is expected to begin later this year, and the system is projected to be operational by early 2026.
The project reflects an innovative approach to integrating battery storage technology directly within a large industrial facility. The 16-megawatt/52-megawatt-hour system will be connected to GlobalFoundries’ switchyard, allowing it to function primarily as a peak shaving resource. This means the system will store electricity when regional demand is low and release it during periods of high demand, reducing stress on the grid and helping maintain stable energy supply levels.
Michael Herbert, Lightshift Co-Founder and Managing Partner, said in a statement, “GF has been a great partner on this project, which will not only reduce energy costs for its Vermont campus but also support regional electric reliability and Vermont’s clean energy goals. This project represents new applications for energy storage within the semiconductor industry, demonstrating how managing peak demand can improve efficiency for industrial operations, and how energy storage can be used to mitigate the impacts of large loads on the electric grid.”
“GF has consistently demonstrated its commitment to sustainable manufacturing and maintaining global competitiveness right here in Vermont, while also being a supportive corporate citizen for the community. Partnering with Lightshift aligns perfectly with these objectives and supports the sustainability goals of our customers, while propelling both GF and Vermont forward,” commented Ken McAvey, General Manager of GF Vermont.
One of the key benefits of this energy storage project is its potential to enhance grid reliability and resilience. By lowering peak energy usage, it will not only support the local grid infrastructure but also help decrease dependence on fossil fuels. This is particularly important in New England, where natural gas is typically the main source of energy during high-demand periods. The project aligns with broader regional efforts to transition to cleaner energy solutions and demonstrates how large industrial users can play a role in advancing sustainable energy practices.
