Snowy Hydro: A Wasteful Project

According to information from the crew working on Snowy Hydro, the reason the Florence tunnel boring machine became jammed while drilling a bend is because it was used for too long between scheduled maintenance. This practice reduces production costs and increases boring rates, however as the cutting wheels wear down, the tunnel is cut to a narrower width. In this case, the machine jammed on a bend where the full width was needed for clearance.

I asked about this at the last Estimates and received a partial admission that the jam was due to worn cutting wheels, but that it was a one-time occurrence. I have requested the maintenance logs for Florence to determine if this was indeed an isolated incident or part of a wider problem.

One Nation believes the Snowy Hydro project is a fool's errand. While the sunk cost (money spent so far) is around $4 billion, completing the project will cost an additional $20 billion. This does not include the drilling region, which is full of asbestos – a can of worms yet to be addressed.

Another problem is that the electricity from Snowy 2.0 is being sent to Victoria and South Australia via Hume Link, which began construction this week. Hume Link involves putting two high-voltage power lines (two towers) across 360 km of bushland, which will require clearing, as well as farmland and forcibly reclaimed private property. This will cost another $5 billion.

All this expense just to provide firming of unreliable wind and solar power, when a zero emission coal plant could do the same thing for a few billion.
