The PJM market is the world’s largest competitive wholesale electricity market, managing power delivery across 13 US states and Washington, DC. It is operated by PJM Interconnection and arranges real-time, day-ahead, and capacity auctions that dictate power generation mixes and prices for roughly 65 million people. At present, market reforms are currently underway to address massive demand from data centres.
The Battery Economics Calculator helps developers and owners evaluate the economic viability of storage projects by combining battery sizing, revenue modelling, ROI (Return on Investment) analysis, and operational assumptions into a single auditable framework. Unlike traditional battery modelling tools, the calculator is connected to the broader enSights EMS and Energy Business Management Platform, enabling organisations to carry investment assumptions through deployment, operations, and optimisation.
Across PJM, storage deployment is rapidly increasing, driven by rising electricity demand, renewable integration and the need for greater grid flexibility. However, many organisations are struggling to confidently evaluate storage opportunities and forecast returns due to the increasing complexity of battery economics.
Project returns are no longer driven by a single revenue source, but by a combination of utility savings, demand charge reduction, energy arbitrage, capacity opportunities, market participation, and incentives. While a growing number of tools help model storage economics, most stop at project evaluation. Organisations are often left to manage operations, market participation, performance tracking, and revenue realization through separate systems and boxes, creating a disconnect between projected and actual results.
At the same time, they are being asked to justify large storage investments to internal and external finance teams, investors, lenders, and stakeholders, creating an urgent need for reliable data and insights on the economic viability of projects.
The enSights Battery Economics Calculator has been designed to address this challenge by using site-specific inputs, such as utility bills, tariff structures, annual energy consumption, peak demand, and operational objectives, to:
Model battery sizing scenarios and evaluate revenue opportunities.
Generate project-specific ROI, payback, and investment recommendations.
Quantify operational assumptions required to achieve projected returns.
Together, these insights help organisations create a clear, auditable investment case, reduce uncertainty around storage economics, and boost investor and lender confidence in the long-term viability of a project.
“Battery economics have become increasingly complex as storage projects rely on multiple value streams, market participation programs, and evolving regulatory requirements” said Alon Mashkovich, CEO and Co-Founder of enSights. “Most organisations can model a storage project, but very few can connect those projections to ongoing operational execution. Our goal is to help customers understand whether a project should be built, how it should be configured, and ultimately how to maximise performance once it is operational. By combining our battery modelling capability with leading strategic partners supporting storage development in PJM, we have created a solution that will allow clients to assess storage opportunities with confidence, create a clear investment case and optimise those assets once live.”
In contrast to standalone battery modelling tools, the Battery Economics Calculator is part of the broader enSights Energy Business Management Platform. Organisations can use the calculator to evaluate investment opportunities, then transition directly into asset management, market participation, operational optimisation, performance monitoring, and EMS control within the same platform. This creates a continuous workflow from investment decision through revenue realisation, helping organisations measure actual performance against the assumptions used to justify the project.
