REVOV Battery Energy Storage System (BESS)
A complete BESS includes a high-voltage battery pack, bi-directional inverter (PCS or hybrid PCS with solar input), energy management system, air conditioner and
The diagram above shows the main components of the BESS, i.e. the battery (energy storage medium), Power Conversion System (PCS) and grid integration equipment. When required, the PCS is used to discharge/charge the battery and supply the energy into/from the network.
Friday, 10 November 2023: Eskom unveiled the first of its kind largest Battery Energy Storage System (BESS) project not only in South Africa but in the African continent. Eskom officially opened the Hex BESS site at Worcester in the Western Cape yesterday.
A BESS site with a capacity of 200 MW/800 MWh holds a substantial amount of stored energy. This is loadshedding? equivalent to a single unit at Medupi Power Station running for an hour.
BESS is another form of energy storage, similar to the more familiar pumped storage hydropower. Batteries do not generate electricity, rather their value lies in a range of ancillary services that can enhance system stability throughout the electricity supply chain.
