Kiwi Power have been awarded planning permission to install a battery storage system at Parc Stormy to provide grid balancing services to the National Grid. During imbalances of supply and demand the batteries will charge or discharge to balance the grid frequency, preventing black outs and spikes.
How can batteries participate in balancing grid frequency?
National Grid is responsible for keeping frequency balanced at 50Hz. A change in grid frequency is caused by an imbalance of supply and demand.
When there is not enough power, batteries are discharged to balance under frequency preventing blackouts and brownouts.
To balance over frequency, batteries are charged to prevent dangerous spikes across electricity infrastructure.
Batteries systems will be installed on site to monitor frequency and charge/discharge to respond during a frequency event.
