A NSW Auditor General’s Report has found that the NSW Government and its agencies grossly underestimated the cost and number of people that would install systems under the Solar Bonus Scheme.
By October 2010, the estimated cost of the Scheme, if it continued the way it was going, would have reached $3.988 billion. More than ten times the original estimate of $362 million. In response to the increased cost, the gross tariff for new applicants was reduced from 60 to 20 cents reducing the estimated cost to $1.954 billion.
It was a statutory requirement that when 50 mega watts of installed capacity was reached, the Government would review the Scheme. By the time the review was completed the installed capacity had reached 101 mega watts.
