NGK Insulators, the Japan-based energy firm, has announced a handover ceremony after installation and test operation of its sodium-sulphur (NaS) batteries for storing electrical energy ordered by MVM Balance, a subsidiary of the Hungarian state-owned energy firm MVM Group.
The NaS batteries were installed inside an MVM thermal power station in the village of Litér near the city Veszprém to be used in a grid storage demonstration project to stabilise the energy grid.
The demonstration project aims to verify the usage of grid storage batteries to store energy during times of surplus and discharging it during periods of shortages.
MVM group said it plans to examine the performance standard for grid batteries to be introduced in the future.
Three units of the NaS battery were installed, which has a maximum DC output of 750kW, with a 4350kWh DC maximum capacity at the time of delivery.
The handover ceremony, which was done after installation and test operation work, involved the State Secretary for Hungary’s Ministry for Energy delivering a speech with MVM Group personnel and government officials in attendance.
NGK is said to have installed NaS batteries in over 300 locations globally.
Attila Steiner, State Secretary, Ministry for Energy for Hungary, said: “The Ministry of Energy aims to secure 1 gigawatt of electric energy storage capacity within Hungary by 2030. This demonstration project is a further step toward achieving this goal. At the same time, it will contribute to energy autonomy, sustainability, and technology reform. Stable energy supplies are essential to the building of resilient communities. This demonstration project is the key to obtaining electric power that local firms and citizens can rely on.”
