The NAS battery system was ordered through BASF Stationary Energy Storage GmbH, a subsidiary of German chemical manufacturer BASF SE and headquartered in Ludwigshafen, Germany.

The delivered NAS battery system consists of one set of four container type units connected in series, with maximum output of 1,000 kW and capacity of 5,800 kWh. The batteries are scheduled to be used in conjunction with a solar power generation system at BASF’s Schwarzheide site, aiming to increase the site’s rate of renewable energy use. This will be the first undertaking of its kind at a BASF production site. The batteries shall further be used on power markets such as intraday trading and control power. The decision to deploy NAS batteries has been made considering that the batteries have received high marks on various fronts.

For instance, the batteries feature a large capacity and ability to discharge electricity over long periods of time, making them well suited to the task of peak shifting the electricity generated by the site’s solar power generation system. They are also highly reliable with an extensive track record. Moreover, the batteries have been granted certification and a test report from UL Solutions, a global independent safety science company. This is BASF’s second NAS battery system installation project, following the first project in 2021 at its Antwerp site in Belgium.

BASF has been working to reduce CO2 emissions as a climate change mitigation measure. It has been actively striving to increase the rate of renewable energy use at its production sites, with the goal of reducing CO2 emissions by 25% from 2018 levels by 2030 and reaching net zero emissions by 2050. This deployment of a NAS battery system at BASF in Schwarzheide will allow electricity stored in the NAS batteries during periods of surplus solar energy to be discharged during times of solar energy`s deficit. Therefore, the NAS battery system will enable renewable energy to be used in some manufacturing processes at the Schwarzheide site almost 24 hours a day.

NGK and BSES established a sales partnership agreement for NAS batteries in 2019 and have expanded NAS battery sales through BASF’s global sales network. NAS batteries are used in various applications including those that involve stabilizing renewable energy, balancing electric power demand and supply, and serving as emergency power sources. They have so far been installed in over 250 locations around the world and have a stable operational track record of more than 20 years. NGK will continue to partner with BSES to further promote marketing and sales activities for NAS batteries, contributing to the expansion of renewable energy introduction and the realization of carbon neutrality globally.
