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 makes 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.
Energy demand management, also known as demand-side management (DSM) or demand-side response (DSR), is the modification of consumer demand for energy through various methods such as financial incentives and behavioral change through education.
Grid energy storage is a collection of methods used for energy storage on a large scale within an electrical power grid. Electrical energy is stored during times when electricity is plentiful and inexpensive or when demand is low, and later returned to the grid when demand is high, and electricity prices tend to be higher.
Duke Energy Corporation headquartered in Charlotte, North Carolina, is an American electric power holding company in the United States, with assets in Canada.
Tantanoola is a town in regional South Australia. The name is derived from the aboriginal word tentunola, which means boxwood / brushwood hill or camp. Tantanoola was originally named 'Lucieton' by Governor Jervois after his daughter Lucy Caroline, on 10 July 1879. It was changed by Governor Robinson to 'Tantanoola' on 4 October 1888. At the 2006 census, Tantanoola had a population of 255.
The net capacity factor is the unitless ratio of an actual electrical energy output over a given period of time to the maximum possible electrical energy output over that period. The capacity factor is defined for any electricity producing installation, such as a fuel consuming power plant or one using renewable energy, such as wind or the sun. The average capacity factor can also be defined for any class of such installations, and can be used to compare different types of electricity production.
Northern Power Station was located at Port Paterson in the Australian state of South Australia about 6 kilometres (3.7 mi) south of the city centre of Port Augusta. It was coal powered with two 260 MW steam turbines that generated a total of 520 MW of electricity. It was operated and maintained by Alinta Energy and was commissioned in 1985. Northern received coal by rail from the Leigh Creek Coal Mine, 280 km to the north. The plant ceased electricity production in May 2016 and decommissioned and demolished over the following few years.
Playford B Power Station was located at Port Paterson in the Australian state of South Australia about 5.5 kilometres (3.4 mi) south of the city centre of Port Augusta. It was coal powered with four 60 MW steam turbines that generated a total of 240 MW of electricity. Playford B received coal by rail from the Leigh Creek Coal Mine, 280 km to the north and drew cooling water from Spencer Gulf, returning it to the sea at an elevated temperature. Commissioned in 1963, it was co-located with the older Playford A Power Station and the larger, newer Northern Power Station. Playford B was mothballed in 2012 and its permanent closure was announced by operator Alinta Energy in October 2015. Prior to being mothballed it primarily operated in the summer, when electricity demand peaks.
The Mount Stuart Power Station is a power station located in Stuart, Townsville, Australia. The station runs on kerosene with three gas turbines that generate a combined capacity of 414 MW of electricity. Mount Stuart was commissioned in December 1998, and operates as a peaking plant. It currently runs on kerosene, but can be converted to natural gas.
The SEA Gas pipeline(South East Australia Gas pipeline) is a 687 km natural gas pipeline from the Iona Gas Plant near Port Campbell in Victoria to the Pelican Point Power Station at Port Adelaide. It connects Adelaide's gas supply to sources from Victoria's Otway Basin, thus increasing the security of natural gas supply to Adelaide. The pipeline is owned and operated by South East Australia Gas Pty Ltd who are owned in a 50-50 partnership by APA Group (Australia) and the Retail Employees Superannuation Trust.
The Kogan Creek Power Station is a 750 megawatt coal fired power station owned by CS Energy on the Darling Downs in Queensland. The $1.2 billion plant is situated at Brigalow, in the Surat Basin between Dalby and Chinchilla.
Tamar Valley Power Station is a $230 million natural gas-fired power station located in Bell Bay in the Tamar Valley, Tasmania. It is owned by Hydro Tasmania, and is immediately adjacent to the decommissioned Bell Bay Power Station, which is also owned by Hydro Tasmania.
Colongra Gas Generation Plant is a 667 MW gas-fired power station located in Colongra, New South Wales, Australia and is the largest gas-fired power station in New South Wales. It will generally be used during peak demand periods in New South Wales.
Solar power in South Africa includes photovoltaics (PV) as well as concentrated solar power (CSP). In 2016, South Africa had 1,329 MW of installed solar power capacity. Installed capacity is expected to reach 8,400 MW by 2030.
A battery storage power station is a type of energy storage power station that uses a group of batteries to store electrical energy. As of 2019, the maximum power of battery storage power plants is an order of magnitude less than pumped storage power plants, the most common form of grid energy storage. In terms of storage capacity, the largest battery power plants are about two orders of magnitude less than pumped hydro plants.
Ladbroke Grove Power Station is a gas-fired power station in the locality of Monbulla near Penola in the Limestone Coast region of South Australia. It was built by Boral Limited in 2000. It is now owned by Origin Energy.
Aurora Solar Thermal Power Project was a planned solar power tower solar thermal power plant to be located north of Port Augusta in South Australia. It was planned to generate 150 MW of electricity after it was completed in 2020. Storage capacity would have been up to 8 hours at full power. The facility was expected to produce 495 GWh of electricity annually. It was to be 30 kilometres (19 mi) north of Port Augusta on Carriewerloo Station.
Reeves Plains Power Station is a proposal from Alinta Energy to build a gas-fired power station at Reeves Plains between Gawler and Mallala in South Australia. The proposed site borders both the Moomba-Adelaide gas pipe and an electricity transmission line. The power station is proposed to use six gas turbines to produce up to 300 megawatts (400,000 hp) of electricity. It is expected to be operated as a peaking plant rather than running full time. The primary source of fuel will be the gas pipeline, however the plant will also be able to operate on diesel fuel, and will have diesel storage on site. Stage 1 is expected to only be two or three of the turbines, generating 100 to 150 MW of electricity. The power station was originally expected to take 12 months to build, and be commissioned in January 2019. An extension of time request granted an additional 12 months in February 2019, but as of November 2019, the Alinta board had not yet decided to make the investment.
Dry Creek Power Station is a power station at Dry Creek in the northern suburbs of Adelaide, South Australia. It is owned and operated by Synergen Power, a joint venture of Engie and Mitsui. The power station has three open cycle gas turbines, each rated at 52MW. It was commissioned in 1973–1974 by the Electricity Trust of South Australia.
