Cape Town produces energy storage cabinet batteries

The City of Cape Town will, in the third quarter of this year, release an RFP for 100MW of battery energy storage systems in an effort to bolster energy security.

In looking at what the introduction of a large-scale battery energy storage system (BESS) would mean for a municipality they looked at multiple use cases to gain an understanding of what flexibility it could offer, what the future impact would be on the power system and establishing the most optimal.

He said the City was looking to energy storage systems to deal with energy security issues and loadshedding, as well as to deal with future alternative variable energy sources, which will introduce greater intermittency to the grid.

Additionally, some of the outlying areas with fairly small loads at the end of 56kV feeders, which only exceed capacity for a few hours in a year, would benefit from the deployment of battery energy storage systems on the line to defer having to build out the network. “It is critical to understand where the cost of tariffs is going.
