Scottish and Southern Electricity [SSE] have submitted plans for a new 300-600MW hydro scheme near Spean Bridge in Lochaber.
It will be near Kilfinnan Farm, south-west of Laggan and north-west of Loch Lochy
With the necessary consultation periods complete, the plans, now with the Scottish Government, involve the construction of a dam and creation of a new reservoir at Loch a’ Choire Ghlais.
The scheme would be for a pumped storage system which involves a higher and a lower body of water – as is the case at Argyll’s once pioneering Cruachan power station. At peak periods of demand, water is released from the higher loch, through the turbinesand out into the lower loc.
When demand is low – at night, for example, electricity at6 a lower tariff pumps the water back up from the lower loch to the upper reservoir.
A key advantage of a pumped storage scheme at Coire Glas is the site’s proximity to the large lower reservoir which would be provided by Loch Lochy.
There is significant elevation of around 500m between the upper and lower reservoir sites over a relatively short distance, cranking up the generative power of the site.
A dam and a new reservoir would be created at Loch a’ Choire Ghlais. The water will transfer between the new reservoir and an underground cavern power station – as at Cruachan – via a headrace tunnel; and then between the power station and Loch Lochy via a tailrace tunnel.
The south planning applications committee of Highland Council will consider the proposal on Tuesday 30th October, council officers are recommending no objections and the decision will finally be taken by the Scottish Government.

With the construction of the High Arrow Dam in 1968 (renamed the Hugh Keenleyside Dam in 1969) the area north of the city of Castlegar to the ghost town of Arrowhead was flooded. Many people were displaced when the water began to rise in 1967 to make way for the second Columbia River Treaty Dam that was built to control the water levels downstream from Castlegar. The city of Trail and all riverside communities below the Canada-US border were spared the threat of continued flooding during the spring melts with the construction of this dam. The water storage also maximized power production downstream at large American dams located along the lower Columbia River. The loss of arable land in the Arrow Lakes Reservoir was devastating to the local population and remains a source of contention to this day.

Pumped storage projects move water between two reservoirs located at different elevations (i.e., an upper and lower reservoir) to store energy and generate electricity. Generally, when electricity demand is low (e.g., at night), excess electric generation capacity is used to pump water from the lower reservoir to the upper reservoir. When electricity demand is high, the stored water is released from the upper reservoir to the lower reservoir through a turbine to generate electricity. Pumped storage projects are also capable of providing a range of ancillary services to support the integration of renewable resources and the reliable and efficient functioning of the electric grid. View Diagram of a Pumped Storage Project.
The Commission has authorized a total of 24 pumped storage projects that are constructed and in operation, with a total installed capacity of over 16,500 megawatts. Most of these projects were authorized more than 30 years ago.

Self-cleansing is a design criterion that satisfies a condition to keep a channel bottom clean from sediment deposits. Deposition of sediment significantly affects on the hydraulic capacity of the channel, and therefore additional costs arise for cleaning the channel. Self-cleansing models in literature are mostly developed for circular channels, which make the limited applicability of existing models. In this study, using experimental data of different cross-section channels, a self-cleansing model is suggested for computation of non-deposition particle Froude number. Considering open channel flow resistance, and using simple channel geometry parameters, a channel cross-section shape factor is incorporated into the model to make it applicable for any arbitrary channel cross-section shape. The robustness of the model is evaluated on different cross-section experimental data to show the applicability of the model on a variety of channel cross-section.


The velocity distribution for time-dependent laminar flow in curved channels is derived. The analysis applies to flows with pressure gradients which are arbitrary functions of time. Numerical results are obtained for developing flow due to a constant pressure gradient. Developing flow in a straight channel is also discussed and it is found that the curvature ratio has only a small effect on the time required to reach the fully developed state.

Ameren Missouri announces a major construction project will begin at Bagnell Dam and its associated Osage Energy Center this spring, to install a series of new anchors and concrete on the downstream side of the dam.
This work is anticipated to cost $52 million and take about 18 months.
“This project is about keeping this vital asset providing clean energy in the long term, using the best possible engineering available today,” says Warren Witt, director of hydro operations at Ameren Missouri.
The 242.59-MW Osage Energy Center, on the Osage River, has operated for 85 years. The last major structural upgrade at Bagnell Dam was completed in the early 1980s with the installation of 277 post-tensioned anchors to hold the dam into the bedrock, Ameren Missouri reports.
This latest upgrade will be conducted in three parts: installing 68 new post-tensioned anchors to hold the dam to the underlying bedrock, placing concrete between the highway piers to add weight to the dam, and installing a new concrete overlay to replace work and cracked concrete on the east and west sections. In total more than 66 million pounds of new concrete will be added, Witt says.
The work “will have no effect on the energy generating capacity of Osage Energy Center,” according to a press release.
Ameren Missouri has a total generating capacity of 10,200 MW from 10 “energy centers.” The company has three hydroelectric energy centers: Osage, 142-MW Keokuk on the Mississippi River in Iowa and 442.5-MW Taum Sauk pumped storage in Missouri.


Construction of a water project in Tanzania which is part of the initial preparations for the development of a huge hydroelectric project in the country is nearing completion, minister for Water and Irrigation, Professor Makame Mbarawa has said.
Mr Mbarawa says that the Stigler Gorge water project is 80% complete and is expected to be operational by mid August. Upon completion the water project will have the capacity to produce 209,000 litres of water per day.
“The water project will supply the contractor and the team at the Rufiji Hydroelectricity site with clean water and the amount of water required.’’ Said Mr Mbarawa.
The project is being implemented through the Dar es Salaam Water and Sewerage Authority (DAWASA) and a Chinese company, China Henan International Cooperation Group Co Limited, is undertaking the construction as a supplement of the ongoing mega water project in Kisarawe District.
Completion of the water project will pave way for construction of the Stigler Gorge hydroelectric project to start in earnest.
But environmentalists are opposed to the hydroelectric project saying it threatens the ecosystem of the Sealous Game reserve thereby endangering animals like lions and rhinos. The hydro-electric project will be located at the heart of the Selous Game Reserve a Unesco world heritage site.
The World Bank has also raised its objection to the project’s construction saying it will create severe water shortages in the Selous Game Reserve to the detriment of the flora and fauna in the area.
In a recent report, the World bank notes that the demand for water in some of the areas where the government is planning to construct hydropower facilities such as Rufiji, Nyasa, Rukwa and Lake Victoria basins already exceeded supply.
“The location of the projects (upstream or downstream) makes it difficult for the projects to be sustainable,’’ reads the report in part.
However, in June this year, President John Magufuli said the project would go on as planned with the tender for the construction of the project being set for end of August. The project is estimated to cost approximately US $4Bn. This is according to Brazil’s Odebrecht, which signed an MoU with the Rufiji River Basin Authority (Rubada) in July 2012 for the development of the project.


The Three Gorges hydroelectric plant in China – the world’s largest hydroelectric plant in terms of installed capacity – has set a new world record for annual power output, China Three Gorges Corporation (CTG) has announced.
Power generation this year at the plant reached the 103.1 billion kWh mark at 8:20 a.m. on 15 November, beating the previous world record of 103.098 billion kWh set by Itaipu Dam in 2016.
Earlier this year, when China’s economic and social development was impacted by the Covid-19 pandemic, the Three Gorges hydropower plant continued to increase its power output and peak load regulating capacity said CTG, transmitting record clean energy to provinces and cities.
The Three Gorges hydropower plant has a total installed capacity of 22.5GW, with 32 units of 750MW capacity and two 50MW units. The plant, with a designed annual power output of 88.2 billion kWh, is a major power source for the West-to-East Power Transmission Initiative and North-South Power Exchange Initiative.


- Phase 1 (1.8GW) of the 3.6GW in north China’s Hebei Province, believed to be the largest of its kind in the world, started operations yesterday.
- The massive pumped storage facility is being developed in two phases of 1.8GW capacity each by State Grid Xinyuan Company, a directly managed subsidiary of state-owned State Grid Corporation of China (SGCC).
- Phase two scheduled for commissioning in 2023.
- The station features a seamless switch between electric, solar, wind, and water potential energy.
Construction on the £2.1bn ($2.7bn) project has been underway since June 2013. It will have a total installed capacity of 3.6 gigawatts and annual designed generating capacity of 6.612 billion kilowatt-hours.
The hydropower station will provide green electricity to the power grid covering Beijing, Tianjing and the northern part of Hebei Province. Together with other pumped storage power facilities constructed earlier, it is expected to enhance the peak regulation capacity of the Beijing-Tianjin-Hebei power grid and the region’s wind power load regulation. And, the project will help to guarantee the power supply to the upcoming 2022 Beijing Winter Olympics.
“The pumped storage plant can help save 480,000 tonnes of coal and reduce 1.2 million tonnes of carbon dioxide emissions every year,” Wu Peizhi, deputy general manager of the power station, told China Media Group in June. “It will help make the Olympics 100-percent the greenest ever in history.”
To achieve carbon emission reduction, developing new sources of energy, such as wind and solar, and adjusting the energy structure are among the priorities. The Fengning pumped storage power station fits the goal.
China is putting efforts to expand its pumped hydro energy storage over the next decade, aiming to have 62 gigawatts of storage facilities operating by 2025, and 120 gigawatts by 2030, according to a plan published by the Chinese National Energy Administration in September.

GEORGETOWN: The Government of Guyana has announced that construction of a multi-million dollar European Union-funded micro-hydro power system at Chiung Water Fall in Kato will begin next year.
The project, which is expected to begin in October 2013, is part of Government’s broader hinterland electrification program.
It will comprise a 330-kilowatt micro-hydropower station. Its primary energy source will be the head waterfall in the Chiung River, which is in the vicinity of Kato village.
Prime Minister Samuel Hinds, who made a visit to the area over the weekend, said the construction of the project is expected to be completed within 18 months.
The project, estimated at EUR2.4 million will be funded under the 10th European Development Fund (EDF) program.
Electrical Engineer at the Office of the Prime Minister, Horace Williams, said that the flow of the Chiung River will be used to generate electricity. The other aspect of the project will be the construction of a pump station that will supply water to a storage facility with a capacity of 7,600 cubic metres.
Williams said the project will provide sufficient generating capacity for the Kato Secondary School to be constructed early next year, as well as existing government buildings such as the nursery and primary schools, police outpost and medical facilities.


A three-dimensional turbulent flow through a multistage centrifugal pump is numerically simulated using a commercial CFD software package. The simulation and analysis include flow fields in rotating impeller and stationary diffuser and is completed in a multiple reference frame. The standard - turbulence model is applied. The analysis of the simulation reveals that the reverse flows exist in the zone near the impeller exit and diffuser entrance, resulting in flow field asymmetric and unsteady. There is a considerable interference on velocity field at impeller exit due to the interaction between impeller blades and diffuser vanes. The hydraulic performance is connected and evaluated with the 3-D computational flow field. The current computation is verified by comparing predicted and measured head.

Happy Valley Underground Stormwater Storage Scheme (HVUSSS), Hong Kong
Drainage Services Department (DSD) of Hong Kong has started the construction works for the Happy Valley Underground Stormwater Storage Scheme (HVUSSS). The project primarily involves the construction of an underground stormwater storage tank with a capacity of 60,000m³ beneath the Happy Valley Racecourse and sports facilities.
The project is being developed with an investment of HK$1bn ($128.9m). The hydraulic study and design works for the scheme were carried out by Black & Veatch.
Initial construction works for the project commenced in September 2011. The major construction works are being carried out by Chun Wo Construction and Engineering Company, a subsidiary of Chun Wo Development Holdings, which won the contract for the project in September 2012. The contract is worth HK$678m ($87.4m).
The first phase of the project is scheduled to come online in 2015. The entire project will be realised by 2018. The project won the International Water Association's (IWA) Project Innovation Award for the East Asia region in the Planning Category in 2012.
Purpose of Hong Kong's Happy Valley project
The low-lying Happy Valley area witnesses frequent flooding during heavy rains. The area particularly witnessed extreme flooding in April 2006, August 2006 and June 2008. The stormwater storage tank will alleviate flooding in the area by accommodating a 50-year flood event.
The project forms part of a comprehensive plan of DSD to control flooding in Hong Kong. DSD has completed projects worth HKD 11bn ($1.4bn) in Hong Kong and plans to invest about HKD $10bn ($1.2bn).
Details of the HVUSSS
The project involves the construction of the stormwater storage tank, an inlet structure, a twin cell box culvert and a movable crest overflow side weir system. The project will also include the construction of a pump station with a capacity of 5,400m³ per hour.
Stormwater during heavy rainfall will initially enter the inlet structure and then be channeled to the diversion culvert. Excess runoff from the culvert will then be conveyed to the storage tank using the movable crest overflow side weir. Water from the storage tank will be pumped and released back to the existing storm-water drainage system on normal days.
The design calls for the use of a movable crest overflow side weir system incorporating supervisory control and data acquisition (SCADA) for monitoring tidal levels and avoiding spillover.
The project is the first of its kind in Hong Kong where integrated one-dimensional, two-dimensional and three-dimensional hydraulic modelling techniques, as well as three dimensional Computational Fluid Dynamics (CFD) modelling, are being applied simultaneously.
The design for the project was carried out keeping environmental concerns in the forefront. The design, which calls for the use of the automated monitoring system for controlling the stormwater flow diverted from the upstream drainage system to the storage tank, enables the use of a smaller storage tank.
The pump house will consume less energy and construction time, while cost will also be cut down due to the shallow tank design.
Constructing the underground stormwater storage system
A catchment area covering about 130ha upstream of Happy Valley will be served by the project.
Works at the project site necessitated the construction of an underground manhole for access. It also involved the laying of two underground pipes in which a fully enclosed conveying belt system was installed for carrying construction wastes to the car park, where it is being transported away using a minimum of 15 dump trucks per hour.
The storage tank will be founded on 533 H-piles which will be placed in sockets in the bedrock to address uplift pressure.
The pump house will be a single-storey building covering an area of about 500m². The twin cell box culvert will measure 400m in length and have internal cell with dimensions of two metres in height and four metres in width.
Other ancillary works at the project site will consist of carrying out the electrical and mechanical works, modification of an existing box culvert, and construction of a stilling basin and a fan room. The project will also involve the remediation works for the sports pitches affected, and landscaping works.
The latest programme of improvement at the Shatin Sewage Treatment Works - the largest wastewater plant in Hong Kong - saw its capacity extended and the disinfection regime enhanced and upgraded.
Tai Po Water Treatment Works, in Hong Kong, was opened in 2003. The Water Supplies Department (WSD) of Hong Kong officially announced the award of contracts for the expansion of the plant in February 2013. The expansion works are expected to be completed by 2017.

The project is planned for completion in Q1 of 2025.https://t.co/Drbqt6s622 pic.twitter.com/5Pw20Ut5tW— Dubai Media Office (@DXBMediaOffice) September 12, 2023
During a visit to the site, Saeed Mohammed Al Tayer, MD and CEO of DEWA, inspected the power generators’ installation, witnessing the assembly of generators and the ongoing construction of service and operational facilities.
Construction of the 72-metre main Roller Compacted Concrete (RCC) wall of the upper dam has been completed, and preliminary measures are to commence for filling the upper dam by the end of the year.
The plant utilises the potential energy of the water stored in the upper dam, which is converted to kinetic energy during the flow of water through a 1.2-km subterranean tunnel.
This kinetic energy rotates the turbine and converts mechanical energy to electrical energy sent to the DEWA grid.
To store energy, clean energy generated at the Mohammed bin Rashid Al Maktoum Solar Park will be used to pump the water through the tunnel back to the upper dam by converting the electrical power to kinetic energy, making the whole project 100 per cent renewable.

Zhejiang Hangzhou plans to build 5 pumped storage projects by 2030
- A 1.2 million kilowatt pumped-storage power station can store electricity that can fill about 120,000 electric vehicles
- These projects will contribute to the realization of carbon peaking and carbon neutrality, filling the gap of Hangzhou pumped storage project
On June 27, 2022, a reporter from Seedao.com learned from State Grid Zhejiang Hangzhou Power Supply Company that in order to speed up the construction of a new power system, five pumped storage projects will be built in Hangzhou before 2030, with an estimated total investment of over 40 billion yuan.
Among them, the two major projects of Jiande Wulongshan and Tonglu Baiyunyuan are expected to start construction by the end of 2022, with an installed capacity of 3.8 million kilowatts. At present, the Jiande Wulongshan project with a capacity of 2.4 million kilowatts has been registered and assigned by the Zhejiang Provincial Development and Reform Commission, and will become the pumped storage project with the largest adjustable capacity in East China. The Tonglu Baiyunyuan Project with a capacity of 1.4 million kilowatts has officially unveiled the project headquarters, and both projects will become the largest local investment projects at present. At that time, the Fuchun River will deliver a steady stream of green energy to the Hangzhou Power Grid. The two pumped-storage power plants are expected to generate an average of 4.32 billion kWh of electricity annually, reducing carbon emissions by 3.7 million tons. Keywords: infrastructure, infrastructure construction, domestic engineering news, planning and investment
"The five large-scale pumping and storage projects that Hangzhou has vigorously promoted are located in Wulong Mountain in Jiande, Baiyunyuan in Tonglu, Lin'an Peak, Qiandao Lake in Chun'an, and Chang'an in Fuyang. We have set up a special class to coordinate and advance the preliminary work of each pumping and storage project." Liu Aixin, director of the Energy Department of Hangzhou Development and Reform Commission, said. In order to ensure the smooth connection of these pumped storage projects to the Hangzhou power grid, the State Grid Hangzhou Power Supply Company coordinated the regional power grid resources, fully considered the site distribution and access requirements of pumped storage power stations, reasonably planned the power grid construction, and accelerated the promotion of the 500 kV Jiande substation. and other related supporting power grid engineering construction.
The five pumped storage projects are accelerating and are expected to be put into operation by 2030. After the completion of the construction, under the current price calculation of pumped storage, the annual power generation income can reach 7.5 billion yuan, which has good investment benefits for the economic development of the western mountainous areas.

SC-Series Side Channel Pumps are typically used for cylinder filling, vaporizer feeding, pumping from underground storage and bulk filling operations.
For those LPG applications where high-differential pressure is necessary or low NPSH conditions exist, such as pumping from underground tanks, the SC-Series multistage side-channel is the pump of choice.
The side channel pump is offered in six different sizes, each ranging from one to eight stages. This provides for a wide range of pressures, capacities, and liquid transfer rates.
The Corken SC-Series pump line utilizes an integral centrifugal and side channel design to create flow characteristics which enable the pump to handle up to 50% vapor and low NPSH conditions. The multi-stage modular side channel design which features one to eight open radial-vane impellers is capable of building differential pressures of over 200 psi (14 bar).

عنوان مقاله [English]
Discharge control valve is a device for volumetric water delivery purposes without using electronic facilities. For analytical modeling of pressurized pipe networks, valves are introduced with their head loss properties. Therefore, any information about the valve head loss is very crucial. In this study, the head loss coefficient in discharge control valves is estimated. For this purpose, control valves were fabricated for the design discharges of 5 and 10 l/s and their performances were tested experimentally. The results indicated that the discharge control valves could accurately deliver an almost constant discharge, irrespective to the pressure fluctuations. The head-loss of entrance and all parts of the valve were investigated experimentally. Measuring the associated head loss coefficients indicated that the entrance head loss is significant in low differential pressures. Also, it was observed by increasing the differential pressure, the total head loss increases as well. From the hydraulic point of view, the main reason creating a relatively constant discharge through the valve is increasing/decreasing the head-loss proportional to increasing/decreasing the differential pressure. Finally, based on Buckingham analysis, empirical formulas were presented to define the head-loss coefficients.

The United States Army Corps of Engineers constructed Bonneville Dam on the Columbia River in the 1930s to improve river navigation and provide hydroelectric power to the Pacific Northwest. This paper demonstrates how the Corps’ approach to the planning and design of the dam’s structures, machines, materials, and processes fostered engineering innovations. These innovations included a new kind of concrete, a portland-pozzolan cement mix that reduced temperature-induced cracking in the massive structure; a new spillway design incorporating energy dissipating structural features; and a new kind of water turbine that enabled efficient power production under widely variable hydraulic flow conditions, adjustable-blade Kaplan turbines. The Corps’ success in the development of innovative engineering designs at Bonneville Dam illustrates the central role of civil engineers in the process of planning, designing, and building major public works.
