Snowy Hydro chief executive Dennis Barnes was paid almost $2.3 million last financial year and his top executives took home more than $1 million each, as huge delays and cost blowouts plagued the renewable energy project.

The five top members of the Snowy Hydro teams are among at least 30 senior public servants and executives of government-owned corporations who are paid more than $1 million, according to an analysis of annual reports by The Australian Financial Review.
