New battery storage system for Gossau ensures grid stability
Stadtwerke Gossau now has a battery storage facility with a capacity of 2.5 megawatts. It was supplied, installed and commissioned by Axpo. The large storage system is designed to compensate for fluctuations in demand and power peaks. Island operation is also possible.
Axpo has installed and commissioned a battery storage facility with a capacity of 2.5 megawatts on the site of the Gossau municipal utility. The municipal utility now has the largest battery storage facility in the region, explained the Aargau-based energy company in a press release. According to the press release, the storage facility is tailored to the specific needs of the municipality of Gossau and the region’s grid topography. The press release does not provide any information on the financial scope of the project.
Stadtwerke Gossau intends to use the battery storage system to compensate for fluctuations in demand and power peaks. It will also process reactive power and contribute to maintaining the grid voltage in the region. It will also help to stabilise the grid in the region by providing system services for the national grid company Swissgrid.
The new battery storage system is capable of stand-alone operation and black start. This means that in the event of a power outage, it can autonomously restore the power supply for units connected to island operation. Relevant companies for maintaining the supply to Gossau can take advantage of this. “What was initiated in 2019 with a parliamentary initiative can be demonstrated five years later,” says Claudia Martin, City Councillor and Head of the Supply Security Department of the City of Gossau, in the press release. “An energy storage facility that guarantees Gossau’s security of supply.”
