Financial & Operational Benefits for Utilities

Case Study: $8M Savings from Massachusetts Municipal Project

The Massachusetts town project is an excellent demonstration of how you will realize huge savings by utilizing a Battery Energy Storage System (BESS) to peak shave. Designed to control and offset high-demand peaks, the project has ultimately saved an astounding $8 million over the years. The feedback from project stakeholders on these services was favourable, with testimonials highlighting the operational efficiencies that came from the cost management and energy reliability that BESS delivered. This case study is not an isolated one, with similar projects around the country and across the world demonstrating the benefits of introducing BESS, providing utilities a forward-looking solution for lowering costs and enhancing grid stability.

Avoiding Peak Capacity Charges Through Strategic Dispatch

Peak capacity charges are also a tax on electric utilities, because they impose high costs on utilities to provide the electricity needed at peak times. During these peaks utilities can save themselves these costs by proportionally discharging their BESS when these peaks occur. This is backed up by data, with the optimally timed dispatching resulting in utility operational cost reductions of as much as 30%. Resources and technology, including sophisticated energy management software, help utilities make decisions about how to best arrange the order of the dispatch and use stored energy most efficiently. Those types of innovations will help utilities handle grid pressure, reduce operational expenses, and pass the value back along the line to consumers."
