The head of Australia’s Renewable Energy Agency (Arena) is optimistic about driving the cost of large-scale solar down to $20/MWh by 2030 through the 30-30-30 vision, focusing on module efficiency and cost reduction. Arena's CEO, Darren Miller, highlights the importance of robotics and AI in achieving this target by reducing labor and civil works costs. The Solar Sunshot program and local manufacturing initiatives will support Australia's green hydrogen ambitions. Arena's $100 million solar challenge attracted global interest, with selected projects expected to trial new technologies in Australia. Additionally, the agency has committed $3 billion to various projects, including the Hydrogen Headstart and Solar Sunshot programs. Arena's focus also extends to grid modernization technologies like battery inverters and grid management schemes. With a commitment to replacing coal-fired grids with renewables, Arena plays a crucial role in Australia's energy transition.
