Benefits and Applications

NAS® batteries play an important role all along the power grids and bring value to various market segments.

The applications range from renewable enhancement and upgrade deferral to microgrid solutions. 



  • Minimization of fossil fuel use: Reduce energy costs and CO2 emissions by combining a generator with an NAS® battery.
  • Time of use shift: Excess power, e.g. from solar, is stored by the battery and shifted from daytime to nighttime. Power supply from grid reduced or even eliminated to achieve autonomous power supply.
  • Stabilization of wind and solar power.
  • Additional resilience to local power generation.

Energy consumers (behind-the-meter)

  • Peak shaving: Reduce demand charges by reducing peak energy demand. A battery is charged at low demand time and discharged during peak time thus cutting power supply from the grid.
  • Time of use shift: Power supply from the grid can be reduced or eliminated by storing excess power and shifting its usage from daytime to nighttime, thus optimizing energy costs.
  • Back-up power and resilience: Continuous power for six hours or more in the event of grid outages.

Virtual power plant

  • Demand response: Supply-demand balance is maintained by aggregation and re-distribution of unused power from multiple consumers for effective utilization of power resources and cost optimization.

For power suppliers

  • Renewable generation enhancement: Stable and reliable power supply is ensured since fluctuations caused by renewable energy, such as wind and solar, are leveled out by the NAS® battery, which absorbs excess energy during peak times of energy generation and provides additional power during demand peaks.
  • Fossil fuel peaker plants replacement: Green alternative to fossil fuel peaker plants. An NAS® battery provides resource capacity of six hours or more per day. 
  • Other use cases: On-peak/off-peak price arbitrage, frequency regulation, ramping services, VAR support and other grid functions.

For energy transmission and distribution companies

  • Investment deferral: Transmission and distribution upgrades can be deferred or even eliminated. Power is imported into a transmission constrained area when loads are light, charging NAS® batteries that are positioned nearby. During peak load time, NAS® batteries are discharged to supplement the power from the transmission lines.
  • Ancillary services: Fast response of NAS® batteries enables reduction of imbalances between demand and supply.
