Given the large amount of sunlight Mildura receives, it is the site for several proposals for large scale solar power in Australia including a massive solar updraft tower proposal in 2004 and 2010. In 2013, Mildura Solar Concentrator Power Station, a 1.5 MW demonstration plant, was commissioned by Silex Systems and it was expected to be expanded to 100 MW by 2017. However, in August 2014, the project was abandoned by Silex, due to lack of commitment to renewable energy by the Abbott government. The government's plans to scrap the praised Renewable Energy Target (RET) in Australia were cited as one of the main reasons for abandoning the project. International scientists criticised this decision extensively, claiming Australia risks being "left behind the rest of the world" if it cuts its plans for renewable energy. The decision to not build the plant may also cause electricity prices to rise significantly in the country.
