Increasingly, generation units are being connected in groups such as a string of wind turbines, photovoltaic panels or battery cells. If a fault along this string causes the protection scheme to open the circuit breaker, then all connected generating units will be simultaneously disconnected from the station bus.
We as System Operator have examined this risk and proposed a new credible event with for industry consultation. This will introduce a new category of risks considered in our reserve management tool and may result in instantaneous reserve procurement costs being allocated to stations with a group of generating units exceeding 60 MW capacity.
Following the consultation if we decide to progress, all participants with existing or commissioning generating units (including BESS) will be required to self-identify any groups of generating units within their stations by 29th August 2025.
Our consultation period opened on Wednesday 21 May 2025 with submissions due by Wednesday 11 Jun 2025.
