Victoria is forging ahead with six new renewable energy plants capable of powering 645,000 homes while the federal government has scrapped its policy to reduce power prices and greenhouse emissions.

On Tuesday the Andrews government announced the three new solar and three wind farms would produce 928 megawatts of power, reducing greenhouse emissions in the electricity sector by 16 per cent over the next 17 years.

The state government had invited private companies to bid to build the projects in a process known as a reverse auction.

It said the reverse auctions had helped it surpass its original goal of delivering 650 megawatts of renewable power.
