Synchronous condenser technology and large-scale battery energy storage will be combined in a single grid connection for power stability.
Siemens Energy is set to deliver a hybrid grid stabilization solution and a large-scale battery storage plant to Shannonbridge, Ireland. The separate technologies will be combined into a single grid connection for energy stability and the increased efficiency of renewable energy usage.
The grid stabilization solution offered by Siemens Energy is a synchronous condenser that utilizes a generator with additional rotating mass from a flywheel. With its stored energy, the condenser offers a power reserve to compensate for frequency variations and securing grid stability.
Siemens Energy’s large-scale battery energy storage system (BESS) is capable of storing or releasing excess renewable energy whenever demand requires. The BESS can fortify the grid and use renewable energy in the absence of intermittent sources, such as solar or wind power. It has a storage capacity of approximately 160 MWh and could supply up to 9,500 Irish households with electricity for a 24-hour period.
“Technical solutions are essential if we are to combat the consequences of climate change and transition to a net-zero grid. Battery storage systems will play an increasingly pivotal role in tomorrow’s global energy infrastructure,” said Tim Holt, member of the Managing Board of Siemens Energy. “By combining our experience in grid technology, the Shannonbridge hybrid solution will help ramp-up renewables by offering storage and stabilization technology in one connection.”
The entire equipment delivery consists of the 4,000 MW synchronous condenser + flywheel, a 160 MWh BESS installment, power conversion systems, energy management systems, and medium voltage equipment. Operators in Ireland will be able to sell inertia, short circuit power, and reactive power generated by the synchronous condenser to the transmission system operator. Siemens Energy will also provide an energy management system, allowing the customer to address market demands and power requirements in real time.
