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.
