Snowy costs blow out but there's light at end of tunnel

Key points

• The cost of Snowy 2.0, the Snowy Mountains hydro-electric expansion, may now reach up to $25 billion. The project was priced at $2 billion when proposed in 2017.
• Its completion has been pushed back to late 2029. Energy Minister Chris Bowen says the project would still provide net benefits and blames geological challenges and early design decisions.
• Tunnelling is now 65 per cent complete. Opposition energy spokesperson Dan Tehan has called for Mr Bowen to resign, which he has refused.
