Snowy Hydro's two main energy projects have had their completion costs double to almost $13bn as delays and rising costs for equipment and staff take their toll.

The giant Snowy 2.0 pumped hydro project in the Kosciuszko national park, first touted by the Turnbull government in 2017 as costing $2bn, was later revised to a cost of $5.9bn. That tally, though, has escalated to $12bn, with that estimate contingent on completion by the end of 2028.
