Under the proposed new system, feed-in tariffs would no longer be a fixed flat rate but would vary depending on the time of day (i.e. peak, shoulder, and off-peak periods). Tariffs would include a Critical Peak Payment and a payment for Avoided Greenhouse Gas Emissions. These changes could add up to a doubling of the feed-in tariff from next year, perhaps even more. Whether or not the proposed new tariff system is adopted next year will be a political decision.
