The lobbyists were getting good signals from the Government and thought their preferred version was over the line. What they didn't count on was State Energy Minister Peter Batchelor, who thought the scheme too generous and costly. In cabinet, Batchelor went head to head with Environment Minister Gavin Jennings and won.

Batchelor's version goes something like this: householders get 60 cents a kilowatt hour — which is generous compared with the 17 cents we pay on electricity bills — but only for the energy exported to the grid. This is called a net feed-in tariff. Batchelor also excluded community groups and businesses from the scheme and limited it to 2 kilowatts.
