Microgrids, DERMS & VPPs
Long-duration storage: the key to leveraging distributed energy resources
Globally, microgrids often rely on diesel generators which are expensive and polluting. ESS delivers a scalable energy storage solution that drives down the cost-per-kWh of clean electricity while efficiently integrating renewable energy so that even remote locations can be powered by sustainable, resilient energy.
The ESS Energy Warehouse™ is designed to serve commercial and industrial customers. Each unit delivers four hours of energy at rated power, enabling microgrid operators to leverage renewable investments and shore up reliability. The ESS Energy Center™ is created for utility-scale applications. This solution delivers up to ten hours of energy in scalable building blocks. This solution is ideal for campus-sized microgrid installations.
DERMs and VPPs
When power providers implement distributed energy resource management systems (DERMS) or virtual power plants (VPPs), ESS technology can play a key role to increase the value and effectiveness of these systems.
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 stored). This provides flexibility to use the battery for a variety of use cases simultaneously:
- Maximize renewable generation
- Manage duck curves without peaker plants
- Meet EV charging peaks
- Reduce system bottlenecks
- Defer substation upgrades, conductor replacements and other grid investments
- Enhance reliability
- Increase grid resiliency
Energy Storage Use Cases
Make renewable energy baseload energy
Silent watch with power
Load following remote grid
Improve generation efficiency
Provide energy security
Use case: 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 generators to operate at peak efficiency, substantially reducing refueling costs and logistics.
