August 1 (Renewables Now) - Japanese ceramics company NGK Insulators Ltd (TYO:5333) will install 2.6 MW of rooftop solar photovoltaic (PV) systems combined with 1.2 MWh of NAS battery rated capacity at its manufacturing sites in Ishikawa prefecture.

NGK said today the PV systems will be located at the Ishikawa plant and its subsidiary NGK Ceramic Device Co Ltd, both in Nomi City.

The ceramics firm expects the green energy system to commence operations in January 2024.

Once up and running, the solar arrays should be capable of generating 2,690 MWh per year to power the manufacturing sites. NGK plans to use the NAS battery as a backup power source when the grid is not reliable.

The combination of the solar panels with the energy storage system will ensure electricity supply to important equipment at the plant for up to 10 hours when power from the grid is interrupted, the Japanese firm explained.

Currently, NGK is working on expanding the use of renewable energy as a strategy to achieve its goal of 50% reduction in carbon dioxide (CO2) emissions by fiscal 2030 and net zero emissions by 2050.
