BNEF reported that the levelized cost of electricity of battery storage systems has halved in just two years to a benchmark of US$150 per MWh for four-hour duration projects, making batteries cheaper for peak shaving than open cycle gas turbines (OCGTs). The report notes that manufacturing scale and standardization, as well as technology improvements, have contributed to this rapid decline in costs. The other factor is that battery projects are getting bigger, both in megawatt (MW) and in megawatt-hour (MWh) metrics. However, longer duration energy storage is not yet competitive, as the cost of batteries, typically lithium-ion, increases rapidly with the discharge duration, meaning that OCGTs are still cheaper for peak shaving for three to five hours.
Nusaned Investment, based in Riyadh, Saudi Arabia and owned by SABIC, and SCHMID Group closed a joint venture (JV) to build manufacturing and technology in the field of vanadium redox flow batteries.
