Key points

• The cost of the Snowy 2.0 pumped-hydro project could reach $25 billion, more than 12 times the original $2 billion promise. Snowy Hydro says the updated target cost is $22.2 billion, with an allowance for a $25 billion scenario.
• The new completion target is late 2029. Energy Minister Chris Bowen says the project remains a good use of taxpayer money.
