1) Renewables Capacity Firming/Ramping

Ultracapacitor energy storage provides multiple benefits to independent energy generators and utilities alike, for renewable generation such as solar and wind as well as traditional fuel energy generation. Ultracapacitor products are uniquely suited to deliver excellent cost of ownership value by providing a long service life and excellent reliability. Within the context of a hybrid ultracapacitor + battery energy storage solution, ultracapacitors are utilized to perform fast response functions and extend battery lifetime.

The variable and intermittent power output from solar and wind generation causes dips and peaks in power output caused by cloud coverage over solar generation sites or fluctuations in wind speed for wind generation sites. Ultracapacitors can firm power output and "ride through” these deviations, and also control the rate at which power ramps up and down to eliminate rapid power swings.

2) Frequency Regulation

There are short term variations in grid power generation and load that lead to frequency fluctuations on the order of seconds to minutes. These fluctuations must be tracked and balanced. Ultracapacitors can be rapidly charged or discharged in response to a generation source frequency spike (over-generation) or dip (under-generation). In some cases, customers can be paid to provide this service.

3) Peak Shaving and Load Leveling
Highly variable loads introduce peak power consumption spikes that can be mitigated through the use of ultracapacitors to rapidly supply and absorb power as needed to smooth power and reduce electricity demand. When utilized in conjunction with batteries, the ultracapacitors serve all fast responding functions and battery capacity can be committed to slower, longer term energy storage.

4) Spinning Reserve
On the grid, a reserve of power must be instantaneously ready to respond to a transmission outage/failure. This reserve commonly comes in the form of natural gas fired peaker plants. These plants are run in idle mode (consuming fuel) so that they can ramp to full power rapidly. Instead of operating a peaker, Ultracapacitors can supply rapid back-up power as a "bridge” to maintain operations until a more efficient, non-idling back-up generation source is brought on line. This enables generators to work at optimum power output, minimize idle capacity, reduce plant wear and tear, and defer construction of new peakers.

5) Voltage Control and Power Quality
When large, fast load demands are placed on the grid, ultracapacitors can rapidly supply power to avoid voltage sag, until a generator or secondary power source comes online.

6) Backup Power
On the grid, a reserve of power must be instantaneously ready to respond to a power outage/failure. Ultracapacitors can supply rapid backup power as a "bridge” to maintain operations until a back-up generation source is brought on line.
