  1. The NSW volatility events on 17 and 20 May and on 16 March were characterised by constrained VNI flows and high (2000 MW) Tumut hydro output. Is the VNI constraint causing the high hydro output or is the high hydro output causing the VNI constraint? Is there a lack of capacity in the Snowy 330 kV network?
