Energy Base
Gigawatt-scale, long-duration energy storage is ready for your next project
Up to gigawatt-hour storage capacity
You can configure the Energy Base to deliver gigawatts of cost-effective energy storage for 8+ hours.
Scalable solution for grid-scale applications
The ability to customize power and discharge durations maximizes project flexibility and delivers cost-efficient energy storage.
A layout that seamlessly integrates with any landscape
Flexible design enables project developers to incorporate unique requirements of various geographies and climates to maximize performance while meeting regulations and community requirements.
American-made
Built in the U.S. and supported by an American supply chain, the Energy Base is supporting American Energy Dominance.
Introducing the Energy Base
ESS’ latest long-duration energy storage (LDES) solution is redefining energy storage, with industry-leading design and operational flexibility to cost-effectively meet customer needs. Each Energy Base project leverages ESS’ proven core technologies to deliver the power, energy and layout customers need. Its modular architecture and the inherent safety of ESS iron flow technology enable compliance with safety regulations and community guidelines, providing peace of mind for all stakeholders involved.
Powered by the Iron Core
At the heart of this innovative system lies a modular building block known as the Iron Core. Each Iron Core incorporates ESS’ proven battery modules and core technology. ESS partners with customers and contractors to cost-competitively deploy pre-established, standardized configurations to meet a customer’s needs. The Iron Core was engineered to deliver the gigawatt-scale storage capacity that the grid needs.
Customizable, scalable and upgradeable
ESS has worked closely with leading engineering firms to develop standard, cost-effective design parameters that enable deployment of gigawatt-scale storage. Energy Base projects can be customized to minimize visual impact and deliver at least 100 MWh/acre energy density. The Energy Base platform is designed to deliver gigawatts of long-duration energy storage in harmony with the new energy landscape.
Safe and sustainable
The Energy Base’s environmentally safe chemistry – mostly iron, salt and water – makes this solution one of the easiest to deploy and maintain.
- Fast and easy permitting.
- No thermal runaway = minimal fire risk in comparison to other technologies.
- Low O&M costs.
- Safe and sustainable materials that are predominately reusable or recyclable .
Unparalleled flexibility
The Energy Base allows the power (the rate of electricity flow) to be decoupled from the capacity (the total amount of energy held). This, combined with unlimited cycling and rapid response time, means that the performance of each Energy Base can be tailored to meet individual customer needs. As a result, users have the flexibility to use the battery for various use cases simultaneously on a project.
Low cost per kWh
An electrolyte based upon easy-to-source materials and standardized site designs using widely available components deliver a cost-effective storage solution. For long-duration applications that rely upon frequent cycling, the iron-flow Energy Base delivers a cost-competitive solution over its 25-year lifetime without requiring augmentation.
