After losing lots of money on the US yield cos about five years ago I swore to never do it again. NEW is starting to look very compelling though. Is there anything wrong with my basic interpretation: Production of 1,500 GWh p.a. 87% contracted our to 2030 at AUD $75/MW = $100m p.a. revenue (minimum). Debt of $750m at 4.5% = $35m p.a. Probably some corporate and maintenance expenses at say $10m p.a Still leaves a lot of profit! I'm getting real tempted to buy.
