One of the key initiatives that propelled Melbourne to the forefront of renewable energy innovation is the Melbourne Renewable Energy Project (MREP). This is a collaboration between 14 local organisations, including the City of Melbourne, universities, cultural institutions, and businesses, that collectively purchased 88 GWh of electricity per year from a new wind farm in regional Victoria. This is equivalent to powering more than 17,000 households, or removing 22,000 cars from the road, for a year.
The MREP was the first project of its kind in Australia, and one of the first in the world, to enable a group of diverse customers to support the development of a new renewable energy facility through a long-term power purchase agreement (PPA). A PPA is a contract between a buyer and a seller of electricity, where the buyer agrees to pay a fixed price for a certain amount of electricity over a specified period of time. This provides a stable and predictable income for the seller, and a secure and affordable supply for the buyer.
The MREP was launched in 2014, and after a competitive tender process, the consortium selected Pacific Hydro as the renewable energy provider, and Crowlands Wind Farm as the renewable energy facility. The Crowlands Wind Farm is located about 200 km northwest of Melbourne, and consists of 39 wind turbines with a total capacity of 80 MW. The wind farm commenced operation in 2019, and is expected to generate enough electricity to power more than 50,000 homes, and reduce greenhouse gas emissions by more than 140,000 tonnes per year.
The MREP has been recognised as a pioneering and innovative project, and has received several awards, such as the Premier’s Sustainability Award, the Banksia Sustainability Award, and the United Nations Association of Australia Award. The MREP has also inspired other similar projects across Australia, such as the Sydney Renewable Power Company, the Canberra Renewable Energy Hub, and the Adelaide Renewable Energy Hub.
