Brazilian power company Cemig has developed a storage system using a remotely operated battery bank to support the traditional distribution network.
According to the company in a release, the system is a first of its kind for the country, providing greater network stability and reduced power outages, especially in locations with more specific demands. The company has already begun the process to implement the new technology in its network.
The Cemig battery bank system takes advantage of times of lower demand (such as at dawn) to store energy in high-capacity batteries, which can then be reinjected into the grid according to the needs of that location.
The equipment can be used for several functions, such as regulating voltage levels during peak hours and even taking over the power supply for a period of time in the event of grid outages for maintenance or due to external factors, such as extreme weather events.
