Our first look at trended LGC production (aggregated by state/territory) and LGC spot prices (monthly average), now possible in NEMreview v7, generates a number of questions...
An article that sums up some decidedly un-quick calculations we've performed - looking over an 8 week period to 13th September to estimate how much wind power has been curtailed by the AEMO.
