Many countries and territories have installed significant solar power capacity into their electrical grids to supplement or provide an alternative to conventional energy sources. Solar power plants use one of two technologies:
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.
The Mildura Solar Concentrator Power Station was a proposed 100 megawatts (130,000 hp) concentrated photovoltaic (CPV) solar PV system to be built at Carwarp, near Mildura, Victoria, Australia. It was proposed by Solar Systems in 2006, which was acquired by Silex Systems in 2010. A 1.5 MW demonstration plant was completed in April 2013. Construction of the larger facility was expected to commence in 2014 and be completed in 2017. However, the expansion plan was abandoned in August 2014 due to a number of factors, including low wholesale electricity prices, a lack of commitment to clean energy by the Australian government and uncertainty surrounding the Renewable Energy Target (RET) in Australia.
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.
Energy in Victoria, Australia is generated using a number of fuels or technologies, including coal, natural gas and renewable energy sources. Brown coal, historically, was the main primary energy source for the generation of electricity in the state, accounting for about 85% of electricity generation in 2008. The amount of coal-fired power has decreased significantly with the closure in 2017 of the Hazelwood Power Station which supplied around 20% of Victoria's electricity, and to a lesser extent with the exit of Anglesea Power Station in 2015. Brown coal is one of the largest contributors to Australia's total domestic greenhouse gas emissions and a source of controversy for the country. Australia is one of the highest polluters of greenhouse gas per capita in the world.
A power purchase agreement (PPA), or electricity power agreement, is a long-term contract between an electricity generator and a customer, usually a utility, government or company. PPAs may last anywhere between 5 and 20 years, during which time the power purchaser buys energy at a pre-negotiated price. Such agreements play a key role in the financing of independently owned electricity generators, especially producers of renewable energy like solar farms or wind farms.
Queensland's energy policy is based on the year 2000 document called the Queensland Energy Policy: A Cleaner Energy Strategy. The Queensland Government assists energy development through the Department of Energy and Water Supply. The state is noted for its significant contribution to coal mining in Australia. The primary fuel for electricity generation in the state is coal with coal seam gas becoming a significant fuel source. Queensland has 98% of Australia's reserves of coal seam gas. An expansion of energy-intensive industries such as mining, economic growth and population growth have created increased demand for energy in Queensland.
As of April 2020, the energy sector in Senegal has an installed capacity of 1431 megawatts (MW). Energy is produced by private operators and sold to the Senelec energy corporation. According to a 2020 report by the International Energy Agency, Senegal had nearly 70% of the country connected to the national grid. Current government strategies for electrification include investments in off-grid solar and connection to the grid.
South Australia is a leader in utility-scale renewable energy generation, and also produces gas and uranium for electricity generation. Gas production is mostly concentrated in the Cooper Basin in the state's north-east. Gas is delivered from these fields by pipeline to users interstate and to Port Adelaide where it fuels three separate gas-fired power plants. Uranium is also mined in South Australia, though nuclear power generation is prohibited nationally. The Olympic Dam mine is the world's single largest known deposit of uranium and represents 30% of the world's total uranium resource. Many utility-scale wind farms and solar farms have been commissioned during the 21st century and geology with potential for geothermal energy has also been identified but is yet to be developed.
A photovoltaic power station, also known as a solar park, solar farm, or solar power plant, is a large-scale grid-connected photovoltaic power system designed for the supply of merchant power. They are different from most building-mounted and other decentralized solar power because they supply power at the utility level, rather than to a local user or users. Utility-scale solar is sometimes used to describe this type of project.
Most of Kenya's electricity is generated by renewable energy sources. Access to reliable, affordable, and sustainable energy is one of the 17 main goals of the United Nations’ Sustainable Development Goals. Development of the energy sector is also critical to help Kenya achieve the goals in Kenya Vision 2030 to become a newly industrializing, middle-income country. With an installed power capacity of 2,819 MW, Kenya currently generates 826 MW hydroelectric power, 828 geothermal power, 749 MW thermal power, 331 MW wind power, and the rest from solar and biomass sources. Kenya is the largest geothermal energy producer in Africa and also has the largest wind farm on the continent. In March 2011, Kenya opened Africa's first carbon exchange to promote investments in renewable energy projects. Kenya has also been selected as a pilot country under the Scaling-Up Renewable Energy Programmes in Low Income Countries Programme to increase deployment of renewable energy solutions in low-income countries. Despite significant strides in renewable energy development, about a quarter of the Kenyan population still lacks access to electricity, necessitating policy changes to diversify the energy generation mix and promote public-private partnerships for financing renewable energy projects.
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.
While being a major oil producing country, the United Arab Emirates (UAE) has taken steps to introduce solar power on a large scale. However, solar power still accounts for a small share of energy production in the country. The country was the 6th top carbon dioxide emitter per capita in the world in 2009, with 40.31 tonnes, but is planning to generate half of its electrical energy by 2050 from solar and nuclear sources, targeting 44% renewables, 38% gas, 12% coal, and 6% nuclear 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.
The Bungala Solar Power Farm is a 220 MW solar power farm in Emeroo and Wami Kata near Port Augusta in South Australia. The first stage was connected to the grid in May 2018, and the second stage was connected to the grid in November 2018. The project gradually reached full power in 2020.
The Sunraysia Solar Farm is a solar farm under construction south of Balranald in south western New South Wales, Australia. It is expected to be completed around the end of 2019.
Daydream Solar Farm is a photovoltaic power station developed by Edify Energy in Springlands, Whitsunday Region, Queensland, Australia. It uses a single-axis tracking system to follow the sun across the sky. It generates up to 180MW DC and 150MW AC.
Kiamal Solar Farm is a photovoltaic power station under construction north of Ouyen in western Victoria, Australia. Stage 1 is expected to be completed by the end of 2019. It is owned by Total Eren, a renewable energy subsidiary of TotalEnergies When completed, stage 1 at 256MW will be Victoria's largest solar farm. Construction began in October 2018. It has energy offtake agreements with Mars Australia, Flow Power and Alinta Energy.
Kidston Solar Project is a photovoltaic solar power station built on top of the former Kidston Gold Mine utilising the tailings storage facility in northern Queensland, Australia. The project consists of two solar farms, KS1 and KS2. The Kidston Solar Project is the first of four projects that comprise the Kidston Clean Energy Hub also occupying this area. A 250 megawatt (MW) hydro-pumped storage power generation project and a 150 MW wind farm make up the third and forth components. The site is located close to an existing substation and transmission line.
