Although renewable energy resources are environmentally beneficial; the variable output of wind, solar and wave generation causes voltage and frequency fluctuations on the power network. NAS system smoothes the output from these resources, bringing increased benefits to society.
For small islands or isolated grids, NAS system optimizes the use of renewable energy.
NAS system stores energy during off-peak periods and discharges at peak periods. The NAS system can replace other types of peaking generation or standby plant to meet growth in peak demand or replace retiring plants.
NAS system can operate independently to supply emergency backup power.
NAS system can optimize the use of power infrastructure assets. NAS system can provide fast acting reserves (spinning reserve), standby reserves, black start and frequency regulation control without the emissions of conventional generating plant.
