Feed-in Tariff
feed-in tariff plan: $4 to $2.5 per electricity
The feed-in tariff scheme is a measure to promote renewable energy under the Control Plan Agreement, and the installation of solar energy or wind power systems at the site can sell renewable energy produced to electricity companies at a higher level than the general electricity cost.
$4 / degrees
System power generation capacity equal to or less than 10kW
$3 / degrees
System-based power generation capacity is greater than 10kW but not more than 200kW
$2.5 / degrees
System power generation capacity of over 200 kW, but not more than 1MW
2033 End of year
Renewable energy systems can obtain feed-in tariff throughout the project use period until the end of 2002/03
Total feed-in tariff
Feed-in tariff per system-generated electricity is available; the amount of electricity used in the premises is at the rate applicable at the time
Approximately 10 years
