Nine solar farms in the north of the Australian state of Queensland have had conditions placed on their ability to send power into the grid, due to system strength concerns. These projects total 783.5 MW, and with a wind farm and two solar plants already placed in the limited state in March, the total under curtailment is now 1.2 GW. These plants may now export 80% or 100% of their power only when any of three sets of conditions are met on the part of several nearby coal and hydro power stations; otherwise, they will be fully curtailed. System strength pertains to the grid’s stability, managing fluctuations in voltage and frequency in the face of a varying balance of supply…
