Solar power is a major contributor to electricity supply in Australia. As of December 2023, Australia's over 3.69 million solar PV installations had a combined capacity of 34.2 GW photovoltaic (PV) solar power. In 2019, 59 solar PV projects with a combined capacity of 2,881 MW were either under construction, constructed or due to start construction having reached financial closure. Solar accounted for 12.4% of Australia's total electrical energy production in 2021.
Renewable energy in Australia is mainly based on biomass, solar, wind, and hydro generation. Over a third of electricity is generated from renewables, and is increasing, with a target to phase out coal power before 2040. Wind energy and rooftop solar have particularly grown since 2010. The growth has been stimulated by government energy policy in order to limit the rate of climate change in Australia that has been brought about by the use of fossil fuels. Pros and cons of various types of renewable energy are being investigated, and more recently there have been trials of green hydrogen and wave power.
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine.
CS Energy is an Australia-based electricity generating company fully owned by the Government of Queensland with its head office located in Fortitude Valley, Brisbane. The company was established in 1997 and employs more than 500 staff. Adam Aspinall is the Board Chair and Darren Busine is the Chief Executive Officer.
The energy sector in Hawaii has rapidly adopted solar power due to the high costs of electricity, and good solar resources, and has one of the highest per capita rates of solar power in the United States. Hawaii's imported energy costs, mostly for imported petroleum and coal, are three to four times higher than the mainland, so Hawaii has motivation to become one of the highest users of solar energy. Hawaii was the first state in the United States to reach grid parity for photovoltaics. Its tropical location provides abundant ambient energy.
The Australian Renewable Energy Agency (ARENA) is an independent agency of the Australian federal government, established in 2012 to manage Australia's renewable energy programs, with the objective of increasing supply and competitiveness of Australian renewable energy sources.
The electricity sector in Australia has been historically dominated by coal-fired power stations, but renewables are forming a rapidly growing fraction of supply. In 2021, Australia's electricity production reached 265 TWh, with coal accounting for 52.9% and natural gas for 18.8%. Renewable sources, comprising solar, wind, hydro, and bioenergy with waste, collectively made up 26.7% of the total electricity generation mix.
A battery storage power station, or battery energy storage system (BESS), is a type of energy storage power station that uses a group of batteries to store electrical energy. Battery storage is the fastest responding dispatchable source of power on electric grids, and it is used to stabilise those grids, as battery storage can transition from standby to full power in under a second to deal with grid contingencies.
Kennedy Energy Park is a wind, solar and storage hybrid power station approximately 20 km south east of Hughenden and 290 km southwest of Townsville in Queensland.
Neoen is a French producer of exclusively renewable energy headquartered in Paris, France. Founded in 2008, it develops, finances, builds and operates solar power plants, onshore wind farms and energy storage solutions. As at 31 December 2023, the company's total capacity was 8 GW, made up of 50% solar, 30% wind and 20% battery storage. Neoen aims to attain 10 GW in operation or under construction by 2025.
Riverland Solar Storage was a proposed photo-voltaic solar power station planned to be built near Morgan in South Australia.
The Tailem Bend Solar Power Farm is a solar power farm near Tailem Bend in South Australia. It has 108MW of generation capacity but is limited to supplying 95MW to the national grid. An additional 85MW is proposed in stage 2. It is developed and owned by Singapore-based Vena Energy, a new name for the former Equis Energy following acquisition by Global Infrastructure Partners in January 2018. The output will be sold to Snowy Hydro for retail sale under its Lumo Energy brand. Stage 2 is also expected to provide battery storage.
Solar River Project is a proposed photovoltaic power station planned to be built near Robertstown in South Australia. The project received development approval from the Government of South Australia in June 2018 and was expected to start construction early in 2019. However, as of November 2021, the project was still proposed to be constructed, but work on site was not expected until at least the second half of 2022.
The Tesla Megapack is a large-scale rechargeable lithium-ion battery stationary energy storage product, intended for use at battery storage power stations, manufactured by Tesla Energy, the energy subsidiary of Tesla, Inc.
ACEN Corporation, formerly AC Energy, is the energy firm under the Ayala Group. The company has over 4,000 MW of attributable capacity in the Philippines, Vietnam, Indonesia, India, and Australia, with a renewable share of 98% which is among the highest in the region.
Shell Energy Australia provides gas, electricity, environmental products and energy productivity services to commercial and industrial customers.
