SPP launches large battery storage facility in Spišská Belá
Slovenský plynárenský priemysel, a.s., continues to expand its energy infrastructure in order to flexibly meet customer requirements in the area of electricity supply.
Investment of more than a million euros
The modern battery storage facility of SPP in Spišská Belá is connected to the distribution network and will be approved in the coming days. The battery storage facility was supported by the state from the Recovery Plan with the amount of 506 thousand euros, with the total investment exceeding one million euros.
The large-capacity battery will be able to provide FCR support services for stabilizing the transmission system and possibly other services. As the share of energy produced from renewable sources gradually grows, the need to maintain a balance between its production and consumption also increases.
"Two battery storage facilities, each with a capacity of 2 MWh, provide a total output of 4 MW. However, the primary use of this resource is to stabilize the transmission system. As the share of energy produced from renewable sources gradually grows, the need to maintain a balance between its production and consumption also increases. The storage facility can thus help stabilize the network frequency at the standard 50 Hz," informed SPP spokesman Ondrej Šebesta.
Quality technology
Two Huawei Luna 2000 battery storage units, each with a capacity of 2 MWh, provide a total output of 4 MW. This capacity would be enough for an average Slovak household for a quarter of a year, but the primary use of this resource is to stabilize the transmission system. The storage unit can thus help stabilize the network frequency at the standard 50 Hz.
This support service is commonly known by the abbreviation FCR (Frequency Containment Reserve – primary regulation). In order for SPP to be able to provide the FCR service with quality, the storage unit needs to be able to respond very flexibly to all fluctuations in the network.
The storage unit uses LFP technology, which has a lower energy density, but can accumulate a much higher capacity and provide higher power without the risk of overheating and fire. SPP plans to launch a similar storage unit in combination with renewable energy sources in its own premises in Bratislava.
