    How much Raise FCAS is needed as inertia reduces?

    The Step Change scenario in the 2022 Integrated System Plan (ISP) is targeting 83% renewable energy generation in the NEM by 2030-31. By then, around 79GW of VRE resources (wind, utility solar, and distributed PV) is expected to have been installed to help replace the 14GW capacity of synchronous generation...

    Australian Chart of the week | Ramping: Brought into focus but always in the frame

    With the release of AEMO’s Integrated System Plan (ISP) comes increased commentary on the need for power system services critical to ensuring the secure operation of the NEM. Of growing importance are services to provide voltage control and system strength, frequency control and inertia, ramping and dispatchability. In this week’s...

    Chart of the week | Cha-Cha Slide: COVID-19 & falling levels of inertia

    The level of inertia on the system is a key contributor to electricity system stability. Inertia is an attribute of the system related to the energy stored in the rotating motors of synchronous generators. It prevents system frequency from falling too quickly after a frequency disturbance (e.g. a generator trip)....
