Store Energy when it’s Cheap – Dispatch when it’s Expensive

Demand charges account for up to 80% of a commercial or industrial electricity bill.

Reduce Your Electricity Spend with Battery Storage

The cost of battery storage has dropped over 80% over the last decade, making it a financially viable and advisable way to address peak demand. Battery storage technology (often Lithium-Ion) is optimal to offset coincident peak demand charges without interruption to a facility’s operations. We charge our batteries when energy is cheapest and discharge when it is most expensive to reduce your demand charges and lower your bill. Battery storage also offers the opportunity to generate additional revenue by participating in Demand Response, among other ancillary grid services. See our projects.

Why Energy Storage?


Storing energy when it’s cheap and dispatching it when it’s expensive generates savings that impact your bottom line.

No Change to Operations

You don’t have to change anything about the way your facility runs; the battery just reduces cost.

Greater Reliability

Our energy storage solutions can respond in milliseconds, ensuring power consistency and quality during grid events.


Energy storage is used to store and dispatch renewable energy including solar and wind power.

Why No Two Utility Bills are Alike

How your utility and third party supplier work together to display your electricity bill varies by company and by supplier. The resulting bill makes it hard to find your coincident peak demand charges, which can comprise up to 80% of the total charge.

Third Party Suppliers and Your Bill

Third party suppliers support you in reducing the cost per kWh of the energy you consume, not the demand charges on your bill. Working with third party suppliers is one way to reduce your utility bill, there are additional ways to deliver dramatic savings. Often, coincident peak demand charges (capacity and transmission charges in PSE&G) show up on your bill from third party suppliers, rather than your utility.
