Long-duration storage: The key to leveraging distributed energy resources
Globally, most microgrids often rely on diesel generators, which are expensive and harmful to the planet. ESS delivers a scalable energy storage solution that drives down the cost-per-kWh of electricity while efficiently integrating renewable energy so that even remote locations can be energy independent with enhanced resilience and reliability.
ESS Energy Warehouse™ is a turn-key shipping-container-sized unit with storage capacity of 400 kWh and storage durations of up to 12 hours, enabling microgrid operators to leverage renewable investments and shore up reliability. The ESS Energy Center™ is a battery-in-a-building solution for capacities starting at 3 MW and storage durations ranging up to 12 hours. That makes this solution ideal for campus-sized microgrid installations.
DERMs and VPPs
When power providers implement distributed energy management systems (DERMS) or virtual power plants (VPPs), ESS can deliver the storage capacity that makes all those other DERs more valuable.
Flexibility is the key to managing DERs, whether through a demand management program or control of aggregated load in a VPP. ESS storage systems decouple power (the rate of electricity flow) from capacity (the total amount of energy held). That gives you the flexibility to use the battery for a variety of use cases simultaneously on a project.
- Maximize renewable generation on your grid
- Manage duck curves without peaker plants
- Ready your system for EV charging peaks
- Ease system bottlenecks
- Defer substation upgrades, conductor replacements and other grid investments
- Enhance reliability
- Increase your grid resiliency
Energy Storage Use Cases
Baseload power, when coupled with renewable energy
Silent watch with power
Load following remote grid
Operate generators at peak efficiency
Use Case Example
Limit reliance on diesel generators in remote locations
Flexible, long-duration storage can serve a constantly fluctuating load, with generators called upon only when needed to recharge the batteries. This allows the generator to operate at peak efficiency, substantially reducing refueling costs and logistics.
