The Borumba Dam Pumped Hydro Power Station is a proposed 2,000 MW pumped hydro energy storage system at Lake Borumba, located in Imbil, south-west of Gympie in Queensland, Australia. First power is expected in 2030. [1] A state-owned entity called Queensland Hydro is coordinating the project. [2]
The land for the pumped hydro scheme was purchased by the Bjelke-Petersen state government following a Cabinet decision in August 1985. [3] Plans for the scheme were announced in September 2022. [2] The project is expected to cost $14.2 billion. [1] Borumba Dam will be expanded for the project. [2] A new dam wall is to be constructed downstream. A second reservoir is needed to be constructed. [2] It will be built at a higher altitude than Borumba Dam.
The Snowy Mountains Scheme, also known as the Snowy Hydro or the Snowy scheme, is a hydroelectricity and irrigation complex in south-east Australia. Near the border of New South Wales and Victoria, the scheme consists of sixteen major dams; nine power stations; two pumping stations; and 225 kilometres (140 mi) of tunnels, pipelines and aqueducts that were constructed between 1949 and 1974. The Scheme was completed under the supervision of Chief Engineer, Sir William Hudson. It is the largest engineering project undertaken in Australia.
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant.
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. Hydropower supplies one sixth of the world's electricity, almost 4,500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants. However, when constructed in lowland rainforest areas, where part of the forest is inundated, substantial amounts of greenhouse gases may be emitted.
The Wivenhoe Power Station is situated between the Splityard Creek Dam and Lake Wivenhoe. The Splityard Creek Dam is situated in hills adjacent to Lake Wivenhoe and is about 100 metres (330 ft) above it. The power station is the only pumped storage hydroelectric plant in Queensland.
The Shoalhaven Scheme is a dual-purpose water supply and Pumped-storage Hydroelectricity scheme located on the South Coast region of New South Wales, Australia.
The Kareeya Hydro Power Station near Tully in Queensland, Australia in a hydroelectric power station that began generating power in 1957. It has a capacity of 88 megawatts (118,000 hp) which is fed into the National Electricity Market. The power station is owned by CleanCo Queensland.
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.
The Borumba Dam is a rock-fill embankment dam with an un-gated spillway located across the Yabba Creek, a tributary of the Mary River, in the Wide Bay–Burnett region of Queensland, Australia. The main purposes of the dam are for irrigation and potable water supply. The resultant impounded reservoir is called Lake Borumba.
Kidston Dam also known as Copperfield Dam is a dam in Lyndhurst, Shire of Etheridge, Queensland, Australia. It is approximately 200 kilometres (120 mi) north of Hughenden and was built for the Kidston Gold Mine. The mine closed July 2001. The lake created by the dam has a capacity of 20,600 megalitres.
Hydroelectric power in New Zealand has been a part of the country's energy system for over 100 years and continues to provide more than half of the country's electricity needs. Hydroelectricity is the primary source of renewable energy in New Zealand. Power is generated the most in the South Island and is used most in the North Island.
Spirit of Ireland is a proposal to build pumped-storage hydroelectricity reservoirs in valleys in Ireland's west coast combined with large-scale on-shore and off-shore windfarms to reduce Ireland's dependence on imported energy and fossil fuels. It would initially involve identifying up to five coastal valleys from counties Donegal to Cork, building dams on their seaward side and flooding them with sea water. These would provide a hydro-power back-up for the wind farms. The proposal has been likened to the construction of the Ardnacrusha hydroelectric power scheme, which was Ireland's first large post-independence infrastructure project and required investment equivalent to 25% of the national budget at the time but met the majority of the state's electricity needs for 50 years.
India is 5th globally for installed hydroelectric power capacity. As of 31 March 2020, India's installed utility-scale hydroelectric capacity was 46,000 MW, or 12.3% of its total utility power generation capacity. Additional smaller hydroelectric power units with a total capacity of 4,683 MW have been installed. India's hydroelectric power potential is estimated at 148,700 MW at 60% load factor. In the fiscal year 2019–20, the total hydroelectric power generated in India was 156 TWh with an average capacity factor of 38.71%.
The Minghu Dam (Chinese: 明湖水壩; pinyin: Mínghú Shuǐbà, renamed the Takuan Dam, is a concrete gravity dam on the Shuili River located 7 km north of Shuili Township in Nantou County, Taiwan. The reservoir formed by the dam serves as the lower reservoir for the Minhu Pumped Storage Hydro Power Station. Sun Moon Lake serves as the upper reservoir.
As of 2018, hydroelectric power stations in the United Kingdom accounted for 1.87 GW of installed electrical generating capacity, being 2.2% of the UK's total generating capacity and 4.2% of UK's renewable energy generating capacity. This includes four conventional hydroelectric power stations and run-of-river schemes for which annual electricity production is approximately 5,000 GWh, being about 1.3% of the UK's total electricity production. There are also four pumped-storage hydroelectric power stations providing a further 2.8 GW of installed electrical generating capacity, and contributing up to 4,075 GWh of peak demand electricity annually.
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.

Snowy 2.0 Pumped Storage Power Station or Snowy Hydro 2.0 or simply Snowy 2.0 is a pumped-hydro battery megaproject in New South Wales, Australia. The dispatchable generation project expands upon the original Snowy Mountains Scheme connecting two existing dams through a 27-kilometre (17 mi) underground tunnel and a new, underground pumped-hydro power station. Construction began in 2019. It is expected to supply 2.2 gigawatts of capacity and about 350,000 megawatt hours of large-scale storage to the national electricity market. It is the largest renewable energy project under construction in Australia. It includes one of the largest and deepest cavern excavations ever undertaken. It also includes the longest tunnels at 27 kilometres in length, of any pumped-hydro station ever built.
