Pilot project: battery energy storage system used for fast frequency reserve

This paper presents results from a Norwegian pilot project where a battery energy storage system (BESS) was tested to identify its capability to perform fast frequency response (FFR) service. The main challenge was to fulfil technical requirements related to frequency response, and develop procedures related to the planning, managing, activation, and delivering of FFR service. The battery energy storage system has an energy capacity of 1.1 MWh and is installed at Skagerak Arena football stadium in Skien, Norway.
