At the start of 2023, the standard 20-ft container system capacity was around 3.35MWh. However, by the end of the year, the 5MWh ESS emerged as the future of the sector, on the back of the larger 300Ah + ESS cells.
The emergence of the 5MWh ESS is a significant development for the energy storage industry. It will allow for the deployment of larger energy storage systems, which will help to integrate more renewable energy onto the grid.
