SUCCESSFULLY TESTED

In 2023, the Schwarzheide site became the first BASF site in the world to pilot the coupling of a PV system and a battery storage system. The result: intelligent energy management and increasingly emission-free production. In addition, it is possible to react more flexibly to grid utilisation and electricity demand. This concept makes renewable energies usable on an industrial scale and meets the very high requirements for supply reliability. Customers and investors in the Industrial Park Lausitz also benefit from this.

About the project

The system installed in Schwarzheide consists of four NAS battery containers and has an energy storage capacity of around six megawatt hours and an output power of one megawatt. NAS batteries are long-term storage systems. They can provide large amounts of electrical energy cost-effectively over a period of six to eight hours and are therefore ideally suited for the integration of renewable energies, especially solar energy. In this way, we are contributing to the energy transition by meeting our customers' needs for stable, safe and efficient energy storage. NAS batteries are manufactured by our partner NGK Insulators Ltd, Japan.

Our support for your energy storage solution

The development of large capacities for storing electricity is considered the bottleneck of the energy transition. As a battery materials location, it is therefore particularly exciting for us to test the possible applications of battery storage systems in the future energy landscape. We support our customers in adapting energy storage solutions for individual applications. We can assess your energy storage needs and perform an initial cost-benefit analysis to determine the optimal design for your battery system, as well as work out the technical layout and system configuration. We optimise the various marketing options for battery storage systems, from dayahead and intraday markets to balancing power markets and the optimisation of your grid fees, for example by reaching the 7000 user hours. In addition, we have a broad network of competent partners who support us with their expertise in all project phases - from consulting and commissioning to maintenance and marketing.

Facts, figures and data

NAS batteries are long-term storage systems with a high energy content that have been developed for stationary use. Due to their optimal operating window of six to 24 hours, NAS batteries are ideally suited for stabilizing and integrating electricity from renewable energy sources into power grids or industrial sites. NAS batteries have been installed at more than 250 project sites worldwide for over 20 years. The installed capacity and energy exceed 720 MW and 4.9 GWh.

Advantages

Discharge time from 6-24 hours

NAS batteries are optimised for various use cases, such as renewable energy stabilisation, grid support, grid services and arbitrage, remote power grids and more

Service life: 20 years / 7,300 cycles

Thanks to the very low degradation rate, NAS batteries maintain their functionality for up to 20 years or 7,300 equivalent cycles (whichever comes first)*.

* The equivalent cycle is defined only by the accumulated discharged energy and is independent of the depth of discharge (DoD). Subject to compliance with maintenance cycles and other technical requirements

High safety

NAS batteries have advanced safety features and comply with the highest safety standards and certifications. NAS battery cells and modules are certified as recognised components according to the UL1973 standard and successfully tested according to UL9540A.

Partner

BASF Stationary Energy Storage GmbH

NAS batteries are distributed by BASF Stationary Energy Storage GmbH, a wholly owned subsidiary of BASF SE. BASF Stationary Energy Storage GmbH (BSES) is a wholly owned subsidiary of BASF SE. BSES distributes the NAS batteries exclusively and develops the NAS technology together with its Japanese partner NGK Insulator Ltd.

The stationary battery storage system is another important step towards greater sustainability in battery production for electric cars. It allows us to use renewable energy almost around the clock, for example for our production of cathode materials or for the production of black mass in the recycling of used batteries for electric vehicles at our site in Schwarzheide. The NAS battery storage system therefore makes an important contribution to reducing the carbon footprint in the battery value chain.

Dr. Daniel Schönfelder

President Battery Materials

Industry needs a diversified supply more than ever. Direct access to renewable energies means a locational advantage that is also important for the further development of the Lusatia region. With the stationary battery storage system, we are not only taking a big step forward here, but also with regard to climate protection targets.
