Battery storage system installed at Stadtwerke Gossau
Baden/Gossau - Stadtwerke Gossau, the municipal utility company for the city of Gossau in the canton of St.Gallen, now has at its disposal a battery storage system with a capacity of 2.5 megawatts. This was supplied, installed and put into operation by Axpo. The large storage system is intended to offset fluctuations in demand and power peaks.
Axpo, an energy company from Baden in the canton of Aargau, has installed and commissioned a battery storage system with a capacity of 2.5 megawatts on the grounds of Stadtwerke Gossau, the municipal utility company for the city of Gossau in the canton of St.Gallen, Switzerland. This is the largest battery storage system in the region, as Axpo explains in a press release. According to the company, the storage system is tailored to the specific needs of the municipality of Gossau and the network topography of the region. However, no details regarding the financial scope of the project are disclosed.
Stadtwerke Gossau intends to use its battery storage system to offset fluctuations in demand and power peaks. It will also process reactive power and help to maintain the mains voltage across the region. The battery storage system will also support efforts to stabilize the grid in the region by providing system services for Swissgrid, the Swiss transmission grid operator.
Isolated operation and black starts are also possible with the new battery storage system. This means that in the event of a power failure, the system is able to autonomously restore the power supply for units connected to the isolated operation. Companies that play a part in maintaining the power supply in Gossau can take advantage of this. “What started in 2019 with a parliamentary initiative has borne fruit five years later”, comments Claudia Martin, city councilor with responsibility for heading up the Energy Security department for the City of Gossau, in the press release. “An energy storage system that guarantees energy security for Gossau”. ce/hs
