Merus™ ESS in 20 MW Wind Farm – One of the Nordic’s largest energy storage in Viinamäki, Finland
Wind power has long been a globally growing way to generate zero-emission electricity. Technological developments and constant reduction of costs, as well as the pressure of climate change to make the energy system emission-free, are driving the transition of wind power to mainstream production of clean and renewable energy. However, weather variations make energy production unstable when using renewable energy. This makes forecasting of electricity consumption and production difficult and the grid needs fast-reacting support for its stabilization from battery energy storage systems. Merus Power’s advanced energy storage system made it possible to level the electricity generation of the wind farm in Viinamäki, Finland, and to participate in balancing the production and consumption in the frequency regulation markets.
Merus™ ESS Energy Storage Solution part of one of the biggest wind farm projects in the Nordic countries
A 6 MW / 6.6 MWh energy storage system provides energy storage for excess wind production for better income on the spot markets. During the windless conditions the energy storage allows a black start ability for the wind farm turbines. The energy storage enhances the power quality while fulfilling the grid code and minimizes losses in different electrical components such as
transformers, cables etc. It also extends the lifetime of different electrical devices and components. The energy storage is participating to the well-paid national frequency regulation reserve markets (FCR).
