In the night from April 16, 2017 to April 17, 2017 on the electrode cable on Priwall peninsula a fault occurred, which resulted in the generation of hydrogen at the fault location as it acted as cathode. The hydrogen got ignited by the generated heat and a 3 metres high flame shot off the ground. As there is no device monitoring the state of the electrode cable, no alert was made to the operators. Fire brigades were first not able to extinguish the fire, but the flame went out when the current was switched off.
