Treasurer Gladys Berejiklian said: "As is normal practice the contracts for the financial advisers for the partial lease of the NSW electricity network will be publicly available on the Government's procurement website".

It is understood the government is starting the "clock" on the 45-day limit for publication of contract details from the first business day after the March 28 state election, which was March 30.

The reason for this is because UBS, Deutsche Bank and Newgate all entered the contracts on the understanding that if the Coalition did not win the election they would not be paid for the work they had done.

In the case of UBS and Deutsche Bank, this involved preparing the scoping study for the transaction, which the government used as the basis for its decision about how it would proceed.

The study informed then-Treasurer Andrew Constance's announcement in December that, if re-elected, the Coalition would pursue a 99-year lease of transmission company Transgrid and 50.4 per cent each of distributors Ausgrid and Endeavour Energy.
