INVESTMENT in wind farm power indicates that Tasmania will be less hydro dependent in the future, according to the Tasmanian Economic Regulator.
The report also says Tasmanians are the highest consumers of energy and have the fifth- highest power prices in Australia.
Hydro electricity accounts for 69 per cent of Tasmania's power, with Basslink contributing 15per cent, thermal 12per cent and wind 4 per cent.
Wind power is set to increase when the 56-turbine wind farm at Musselroe, with a capacity of 168 megawatts per hour, begins this year, adding to the 140-megawatt capacity of Woolnorth.
The Energy in Tasmania Performance Report released in January said Tasmania had a total installed capacity of 2798 megawatts, with a customer load of 10,670 gigawatt hours.
"Tasmania's average annual generation capacity is forecast to meet its needs for the foreseeable future, with the bulk of electricity continuing to be supplied by hydro-electric generation," the report said.
"Thermal generation from Tamar Valley Power Station, renewable energy from wind farms and the availability of electricity through Basslink should ensure that any deficiency between available hydroelectric supply and peak demand can be met."
It is believed $1.25 billion has been spent on diversification investment.
The report said Tasmanians consumed the highest amount of energy.
A need for heating in the cooler climate led to the state's consumption being double that of Queensland.
