Price fixing: Dr Barry Manor, Sustainability Consultant, takes a closer look at what is happening in the electricity market at both state and federal levels. At a state level South Australia’s new premier, Steve Marshall, has undertaken to honour any contracts in the renewable energy sector that were drawn up under his predecessor Jay Wetherill. The promise to supply 50,000 homes with Tesla power walls is likely to continue to some extent because the first 1,000 homes to get solar panels and batteries will be government housing. This will help those households hedge against retail costs going up but it is also the beginning of a distributed battery which can also help stabilise the South Australian electricity grid.
