Energy Storage System
Over the decades, several different power retention methods have been devised to capture and store energy so that it can be fed back to the grid when it is most needed to produce enough energy to meet the ever-fluctuating demands on electric grid. These are what we call Energy storage systems. Energy Storage System (ESS) is a device or group of devices assembled that is to convert the electrical energy from power systems and store energy in order to supply electrical energy at a later time when needed. An ESS helps to effectively use and manage the electrical energy also expect the benefit of stable electricity supply and cost reduction. Examples of these systems include flywheels, solid-state batteries, ultracapacitor or supercapacitor, pumped hydroelectric storage dams. By 2021, South Africa had started The Eskom Distributed Battery Energy Storage Systems project which involves the development of 360 MW storage system (equivalent to 1440 MWh with 4 hours storage per day) at various Eskom distribution sites in several provinces including Western Cape, Eastern Cape, Northern Cape and KwaZulu Natal. The aim of the project is to stabilize the grid in the country and to reduce rotational load shedding and energy curtailment by significant values.

Hi, Vivian Nabisere!
This is your mentor, Yoon.
Thank you for introducing the concept of ESS and their applications in South Africa.
It is very interesting to know that the Eskom Distributed Battery Energy Storage Systems project involves developing of 360 MW storage system.
Great job on writing the thematic report.
I am looking forward to reading your following report!

Hello, this is your mentor Minkyung.
Thank you for sharing your knowledge of the ESS. If you could provide some more details about the examples of ESS or some statistics related to The Eskom Distributed Battery Energy Storage Systems Project, your report would be much richer in content.
Great job writing November thematic report, and keep up the work :)
