Vast Solar had built the nation's first solar thermal standalone plant at Forbes, NSW. It will generate 6MWth of electricity. Storage will enable electricity to be pushed into the grid 24 hours a day. There are plans to construct a 30MW operation, and other countries are showing interest in having similar plants established by Vast Solar. The big step has been with improved storage making a viable day and night supply. The new plant has been called the concentrated solar thermal (CST) system because it continually provides power.
Wind generation is changeable. Some days there is no wind so no electricity is produced. Plants can be built in windy regions with wind generators alongside as backup.
Tony Abbott's intention to close all such plants to protect the coal industry is backward looking. He is blind to the changes that are occurring in the world. Demand for coal will fall as countries move to gas and pollution free production systems. Anyway, Tony Abbott's plans will not pass the Senate.
