Open Programme Extension Transmission Network Georgia – Component 2:
SS Ksani – Kazbegi Interconnection Project
The Project aims at expansion of 500 kV backbone transmission network of Georgia. Several hydropower plants are under construction near Stepantsminda (Kazbegi) with total planned installed capacity of 400-500 MW. Construction of the new 500 kV overhead transmission line (“OHL”) from SS Ksani to Stepantsminda is scheduled for integrating such capacity into the Georgian electric power system, and improving power flow towards Russia.
The length of planned OHL is about 100 km. It will be designed with specifications applicable to 500 kV rated voltage. At the first stage, the line will be operated at 110 kV, i.e. will be connected to 110 kV side of SS Ksani, to ensure evacuation of the output generated by hydropower stations that are under construction around Stepanstminda. In longer perspective, in parallel to construction of the 500/110 kV substation near Stepntsminda, and development of 500 kV power network in the south regions of Russia, this OHL will be switched to 500 kV thus serving as additional 500 kV link with Russian power grid.


Enhanced water drainage basin map
Rio Tinto Kennecott has started a project to improve water retention basins on the south side of the Bingham Canyon Mine. The project will improve four of six basins by enhancing capacity and mitigating stormwater runoff on historic south facing waste rock dumps when large rainfall events occur.
The work will comprise of creating new and expanding additional water retention basins that will be engineered to handle a minimum of a 100-year, 24-hour storm event. Areas disturbed as a result of this work will be progressively revegetated with native shrubs and plants, and the project has the potential to enable future reclamation of Kennecott’s south facing dumps. Kennecott will also continue to evaluate options to improve drainage in the two remaining south basins while work takes place.
Kennecott will mitigate impacts to surrounding communities by regularly inspecting and maintaining controls put in place as part of the stormwater protection system. In addition, work will be sequenced to minimize ground disturbance, and water trucks will be used to control dust as needed.


Meanwhile at Roosevelt Dam...The construction of the dam was initially completed in 1911 at the cost of $10 million with a National Historic Landmark designation to follow. It was the largest masonry dam at 280 ft high and 723 feet in length. In its' original state, the top of the dam served as a convenient and practical bridge across the newly formed lake.
Between 1989-1996 Roosevelt Dam went under a massive renovation and expansion. The masonry dam was incased in concrete and raised by 77 feet making it a grand 357 feet in height thereby increasing the storage capacity of the reservoir by 20%. The renovations also included, rehabilitation of the hydroelectric plant, a realignment of Highway 188 to cross over the newly built Theodore Roosevelt Lake Bridge, and a tunneling project known as the "Lake Tap".
Shortly after completion of the project the region entered an extended drought. The new storage capacity was not used at 100% until February 2009.

GET provided the soils investigation and geotechnical engineering evaluations for the Lightning Point Living Shoreline project for the Nature Conservancy as part of the Moffatt and Nichol team. The project consists of the reclamation of a portion of shoreline near the Bayou La Batre harbor navigation channel by constructing 1.5 miles of overlapping segmented breakwaters along the shoreline to the west and east of the channel as well as constructing two jetties (700 to 800 feet long) at the mouth of the channel. In order for the barge to transport and place the rip rap for the breakwaters construction, shallow channels had to be dredged to facilitate barge access. Once the breakwaters were installed, hydraulic fill was placed between the breakwaters and existing shoreline.
Geotechnical analyses included ultimate bearing capacity of the near surface soils with respect to supporting breakwaters, long-term settlement projection of the breakwaters, stability of the Bayou La Batre Port navigation channel side slopes after placement of breakwaters and hydraulic fill, side slope stability of the temporary barge access channels during breakwater construction, long-term settlement of the hydraulic fill and insitu foundation soils. The project also included providing infiltration rates of the soils and pavement recommendations for the nearby public boat launch facility

Performance Curve (Speed: 2900RPM) for your more options
Explanation of structural features
If the impeller of is pump is balanced, the cavity with soft packing is connected with the impeller suction. If the liquid at the inlet of the impeller is in a vacuum state, it is easy to enter air along the surface of the shaft sleeve. Therefore, a packing ring is installed in the packing cavity, and the pressure water in the pump chamber is led to the packing ring for sealing through the small hole on the pump cover. If there is no balance hole in the impeller of the pump, because the liquid pressure on the back of the impeller is greater than atmospheric pressure, there is no air leakage problem, so the packing ring can not be installed. The pump body and cover of is water pump are divided from the back of impeller, which is commonly known as back door structure. The advantage of is pipeline centrifugal pump is that it is convenient for maintenance. The pump body, suction pipeline, discharge pipeline and motor are not moved during maintenance, and only the intermediate coupling of the extended coupling is removed to exit the rotor part for maintenance. In order to avoid shaft wear, the shaft sleeve protection is installed at the position where the shaft passes through the packing chamber. There must be an O-ring between the shaft sleeve and the shaft to prevent air intake or water leakage along the mating surface.

The Pinnapuram integrated renewable energy with storage project (IRESP) is a 3.6GW hybrid renewable energy project comprising a 2GW photovoltaic (PV) solar farm, a 400MW wind farm, and a 1.2GW pumped storage hydroelectric facility proposed to be developed in the Pinnapuram village, in the Kurnool district of Andhra Pradesh, India.
The hybrid solar-wind-pumped storage project is being developed by Greenko, a renewable independent power producer (IPP) based in India.
A Memorandum of Understanding (MoU) was signed between Greenko and the Government of Andhra Pradesh in February 2018, while a pre-feasibility study for the project was completed in the same year.
The detailed design and engineering contract for the pumped-storage component of the project was awarded in March 2020. The Pinnapuram pumped-storage hydropower project is estimated to cost approximately £600m ($725m).
The Pinnapuram IRESP is expected to be India’s first and one of the world’s biggest such facilities to supply schedule power on demand (SPOD). Designed for both peak load and baseload operations, the integrated facility will be capable of generating up to seven billion units of electricity a year.
Pinnapuram pumped storage power plant make-up
The Pinnapuram pumped storage hydroelectric facility will comprise a lower reservoir, an upper reservoir, and a subsurface powerhouse measuring approximately 240m-long, 24m-wide, and 58m-high.
The powerhouse will be connected with six tunnels and penstock pipes and will be equipped with eight Francis type, vertical shaft, variable speed, reversible pump-turbine units. The turbines will operate at a rated head of 134m.
Each of the penstocks will be 760m-long with a 7m-diametre. One of the six penstocks will be bifurcated into two penstocks.
The facility will also house a 420kV gas-insulated switchgear (GIS) along with step-up transformers near the powerhouse.
Pinnapuram pumped storage facility reservoir details
The lower reservoir for the Pinnapuram pumped storage hydroelectric facility will be the existing Gorakallu (Narasimharaya Sagar) reservoir which is located near Gorakallu village in the Nandyal Mandal, approximately 80Km away from Kurnool.
The upper reservoir for the project will be created by constructing a 49m-high dam near Pinnapuram. The upper reservoir will be created across Muni Madugu and will have a catchment area of approximately 9.45km2.
The live storage capacities of the lower and upper reservoir will be 12.44 thousand million cubic feet (TMC) and 1TMC respectively.
The pumped storage facility will utilise approximately 1,140MW of electricity to pump 1TMC of water from the lower reservoir to the upper reservoir for storage in 9.2 hours.
While operating in turbine mode, the facility will generate up to 1GWh of electricity by utilising 862.5 cubic metres per second (Cumec) of the design discharge of stored water from the upper reservoir.
The Pinnapuram integrated renewable energy facility will have a central pooling station to gather electricity from each of the three components of the project.
The electricity from the Pinnapuram IRESP common pooling station will be evacuated into the national grid through connection to the Power Grid Corporation of India’s (PGCIL) 765/400/220kV substation near Orvakallu.
AFRY India, a subsidiary of Swedish engineering and consulting company AFRY, was awarded a £2.2m ($2.5m) contract by Greenko Energy Projects for the detailed design and engineering services for the Pinnapuram pumped storage hydropower facility in March 2020.
India-based Aarvee Associates Architects Engineers and Consultants was engaged to prepare the pre-feasibility study report for the Pinnapuram IRESP.

After the construction of the project, it can realize the natural accumulation, natural infiltration, natural purification and Sustainable water cycle. In the construction process of the project, the environmental protection concept of "sponge city" was fully used for reference. Five regulating pools for rainwater collection and 2451 meter long open channel for regulation and storage were successively built in the airport flight area and public area. An artificial landscape lake with an area of 210000 square meters has been built in the public area. The total volume of rainwater collection facilities in the whole site will reach 2.31 million cubic meters, which is equivalent to 2.5 Kunming lakes, three times of the daily average water flow into Beijing of South-to-North Water Transfer Project. In addition, the drainage system of Daxing airport fully considers the influence of the discharge water on the surrounding water system in the flood season, and adopts the secondary drainage system, which is composed of rainwater pipe network (drainage ditch), regulating pool, pump station and open drainage channel. When the airport encounters continuous heavy rainfall, the airport drainage system cuts the peak of rainwater for many times, so that the rainwater flows horizontally and automatically into the drainage channel, avoiding the airport rainwater from forming a flood peak and impacting the river channel. Relevant director of Daxing airport construction headquarters said that the drainage system of Daxing airport can not only play a role in rainwater collection and stable drainage, but also play a major role in regulating the "small ecology" of the airport.

The existing Lake Major Dam was constructed in the 1940's. It is a timber crib structure and has reached the end of its service life. The dam must be replaced in order to enhance public safety and protect the integrity of the Dartmouth water supply.
Construction is anticipated to begin in June 2018 with the new dam to be finished by December 2018. Removal of the existing dam and final landscaping is anticipated to be complete by Fall/Winter 2019.
The new dam will provide significantly more flexibility to manage water levels upstream and downstream of the dam, it will also provide:
- More storage in the reservoir to help mitigate periods of drought
- A fish ladder designed in accordance with the Department of Fisheries and Oceans (DFO) requirements to improve fish migration
- Two sluice gates to provide environmental flows to support downstream aquatic life
- More reliability and a 50+ year lifespan
- Reduced flood related risks.
The design of the new dam meets the Nova Scotia Environment requirements including conformance with an Environmental Assessment approval acquired in 2017.
Lake Major Road will not be closed during construction of the new dam. There will be increased construction traffic in the area surrounding the dam construction site, and appropriate construction signage will be used along Lake Major Road.
In order to safely complete this work, the contractor will construct the dam in phases within a cofferdam system. This will allow the worksite to be isolated from the Lake and minimize the impact on aquatic life and the environment. As a result of the Environmental Assessment, the project is required to follow an Environmental Protection Plan that is specifically tailored to ensuring the work is completed safely and with no negative environmental impacts on Lake Major and the Little Salmon River.
The Lake Major Dam Replacement Project is budgeted at just over $4.5 million with $3.4 million coming from federal/provincial funding with project wrap-up by August 31, 2019.


Chinese company Three Gorges Corporation (CTG) is actively working on installing six new power projects in Pakistan which would have combined capacity of generating 2733MW, said Sheng Zhendong, the company’s senior official.
The projects are 720MW Karot hydropower project, 1123MW Kohala Hydropower project, 640MW Mahl Hydropower project, 49.5MW first wind power project, 99MW second wind power project, and 100MW first solar PV project. The cost of all these projects would be $6 billion, However, Karot power project would be on the priority list because it comes under CPEC projects—according to BRecorder.
The company is not only installing the power plants in Pakistan but it is also involved in developing the whole mechanism and solution for generating clean energy in Pakistan. The corporation will conduct scientific research design, cascade development, Indus River Basin Planning and will become a provider of whole industry chain solution, said the official in an interview with the reporter.
The Karot Hydropower project which is located on Jhelum River east of Islamabad is at top most priority currently, the construction on this project was started back in 2015, the project would be up running by 2020.
The projects are being developed on BOOT, Build-Own-Operate-Transfer basis which will have concession periods of 35 years including 5 years of construction.
In a long-run, the corporation will focus on investing in more hydropower projects on Indus river upstream. These projects will include 2300MW Pattan hydropower station, 4000MW Thakot hydropower station and 4500MW Diamer Basha hydropower station with a combined capacity of 10.8GW.


North Wall Quay Dublin
Construction of complex deep drainage outfalls utilising trenchless methodologies for new development in running sands on the quay walls of the Liffey River in Dublin City.
JCL were engaged by Walls Construction to construct both the foul and storm reticulation along North Wall Quay for the new Dublin Landings Development. The project was extremely complex as the proposed design invert levels were six metres below ground level and five metres below the high tide level of the River Liffey. An existing 450mm 40bar Gas Networks Ireland transmission main also crossed the alignment of the trench 1.2m above the pipe invert level. JCL provided the engineering solutions to overcome the complexities on the project. Two segmental shaft were sunk eight metres below ground level and a fifty five metre 450mm diameter bore was completed on line and grade between the shafts in running sands.


The Gate to Chemical Efficiency: How Gate Valve Suppliers Optimize Flow Control
Feb 18,2024Read More
The definition of a check valve refers to a valve that automatically opens and closes the disc depending on the flow of the medium itself to prevent the medium from flowing back. It is also called a check valve, a one-way valve, a reverse flow valve and a back pressure valve.
Check valve is a kind of automatic valve. Its main function is to prevent the back flow of the medium, prevent the pump and drive motor from reversing as well as the release of the container medium. Check valves can also be used to supply pipelines for auxiliary systems where the pressure may rise above the system pressure. MstnLand, as a professional China swing, disc, in-line and lift check valve manufacturer, provides various check valves.
1. Swing check valve
The disc of the swing check valve is disc-shaped, and it rotates around the shaft of the valve seat channel. Because the inner channel of the valve is streamlined, the flow resistance is smaller than that of the lift check valve. It is suitable for low flow rate and non-return valve. Large diameter occasions with frequent changes, but not suitable for pulsating flow, and its sealing performance is not as good as the lifting type. Swing check valves are divided into three types including single valve, double valve and multi-half valve. These three types are mainly classified according to the valve diameter. The purpose is to prevent the medium from stopping or flowing backwards and weaken the hydraulic shock.
2. Lift check valve
A check valve whose disc slides along the vertical centerline of the valve body. A lift check valve can only be installed on a horizontal pipeline. A round ball can be used for the disc of a high-pressure small-diameter check valve. The valve body shape of the lift check valve is the same as the stop valve (which can be used in common with the stop valve), so its fluid resistance coefficient is relatively large. Its structure is similar to the stop valve, and the valve body and disc are the same as the stop valve. The upper part of the valve disc and the lower part of the valve cover are processed with guide sleeves. The disc guide can be moved up and down freely in the valve guide sleeve. When the medium flows downstream, the disc opens by the thrust of the medium. It drops down on the valve seat to prevent the medium from flowing back. The direction of the medium inlet and outlet channel of the straight-through lift check valve is perpendicular to the direction of the valve seat channel. The vertical lift check valve has the same direction of the medium inlet and outlet channels as the valve seat channel, and its flow resistance is smaller than that of the straight-through type.
3. Disc check valve
A check valve in which the disc rotates around a pin shaft in the valve seat. The disc check valve has a simple structure and can only be installed on a horizontal pipeline with good sealing performance.
4. In-line check valve
A valve in which the disc slides along the centerline of the valve body. In-line check valve is a new type of valve. It is small in size, light in weight, and good in processing technology. It is one of the development directions of check valves. But the fluid resistance coefficient is slightly larger than that of the swing check valve.
5. Compression check valve
This kind of valve is used as a boiler feed water and steam shut-off valve, it has a comprehensive function of lift check valve and stop valve or angle valve.

HYDRO ELECTRIC POWER PLANT:
1 Components Of Hydro Electric Power Plant
2 Working Principle Of Hydro Electric Power Plant
3 Classification Of Hydro Electric Power Plant
1 COMPONENTS OF HYDRO ELECTRIC POWER PLANT:
Water is collected during rainy season
• It is stored in the reservoir.
• A dam is built across the river adequate water head.
• It is a passage through which water flows from reservoir to turbine.
Surge Tank :
• It is installed along the penstock (between turbine and reservoir)
• To control or regulate the sudden water over flow and to protect the penstock from bursting.
• It reduces the pressure and avoids damage to the penstock due to the water hammer effect.
• When the load on the turbine is decreased there will be a back flow, which causes increase or decrease in pressure. It is known as water hammer.
• Power House :
• It is building that houses that water turbine, generator, transformer and control room.
• Water Turbine:
• Water turbines such as Pelton, Kaplan and Francis are used to convert pressure and kinetic energy of flowing water into mechanical energy.
• Draft Tube:
• It is connected to the outlet of the turbine.
• It refers to the downstream level of water discharged from turbine.
• Generator :
• It is a machine used to convert mechanical energy into electrical energy.
• Step up transformer:
• It converts the Alternating Current (AC) into high voltage current suitable for transmission.
2 WORKING PRINCIPLE OF HYDRO ELECTRIC POWER PLANT:
• It uses the potential energy of water of water stored in a reservoir.
• The water from the reservoir through a penstock and then forced through nozzle or nozzles before reaching the turbine.
• The hydraulic turbine converts the kinetic energy of water under pressure into mechanical energy.
• The shaft of the turbine is coupled to a generator that generates electricity
• The electricity generated is fed to the step-up transformer to increase its voltage.
• Power is fed to the transmission lines for distribution.
• The output power of Hydel power plant depends on the head of water stored in the reservoir and the quantity of water discharged
3 CLASSIFICATION OF HYDRO ELECTRIC POWER PLANT:
Factors to be considered for the location of hydro electric Power
Availability of Water:
Adequate water must be available with good head.
Cost and type of Land:
Bearing capacity of the land should be good to withstand huge structures and equipments.
Storage of Water :
A dam must be constructed to store the large quantity of water in order to cope with variations of water availability through out the year.
Transportation Facilities :
The site should be accessible by rail and road for easy transportation of equipments and machinery.
Pumped storage facilities :
The pumping facilities to reuse the water should be possible.
Merits of Hydro Electric Power Plant:
• Requires no fuels and hence pollution free.
• Low operating cost.
• Simple in construction and requires less maintenance.
• Skilled personnel is required for construction.
• High cost of transmission as plant is normally required far off from hilly areas.
• Period of delay causes the delay in the commissioning of the plant.
• Construction of new hydel plant may need rehabilitation of people and payment compensation for land acquisition.

This article introduces a new mathematical model that predicts the pressure drop in a tangential inlet cyclone. The model calculates the pressure drop from the frictional losses in the cyclone body, using a wall friction coefficient based on the surface roughness and Reynolds number. The entrance and exit losses are also included in the model by defining new geometrical parameters. The pressure drop coefficient is obtained as a function of cyclone dimensions and operating conditions. The model is validated by studying 12 different cyclones presented in the literature. Comparison of the model results with predictions and measurements published in the literature show that the new model predicts the experimental results quite well for a wide range of operating conditions covering a flow rate of 0.3-220 l/s and a temperature range of 293-1200 degrees K, in different cyclones. The pressure drop coefficient is also examined in view of the outlet pipe diameter, friction coefficient, surface roughness, and Reynolds number.


A physical model, built at an undistorted scale of 1:15 tested the original design of the six drum screen and nineteen cooling water pump intake connected to header bay. The capacity of origin water intake including huge pump station and drum screen is 400,000 m3/hr. The study objectives were to evaluate as-designed screen bay and pump bay performance and to propose design modifications to optimize intake flow conditions with respect to head-losses, uniformity of the approach flow, evenness of pump throat velocity distribution, and free and subsurface vortex formation. The model was built and operated in accordance with froude-number similitude. It allowed accurate representation of complex flow patterns caused by the physical geometry of the approach bay and pump bays. The major factors that can affect the selection of a concept and design development for a water intake are: a) The occurrence of dead water zones, flow separation or reverse flow b) Vortex building and air entrainment in the pump compartments c) Submerged vortices building in the pump compartments d) Low velocity area e) Strong rotational flow f) Strong cross flow appear in front of pump units g) Pre rotation in the pump suction lines. Dye injection was used to examine the stratified flow behavior along water. The existing design of the pump bays was found to produce a uniform, symmetrical flow distribution in the approach flow, weak but persistent floor and side-wall-attached submerged vortices, avoiding cross flow and reverse flow in front of the pumps and negligible swirling motion in the pump suction. Modified design includes (i) profiling low velocity area (ii) adding flow deflectors along inner walls (iii) infill area of low velocity (iv) adding suspended baffle in front of drum screens (v) adding diffuser block in front of pumps (vi) provision of floating booms in front of pumps.

The Government’s announcement of $12 million in funding to replace the Kirikiri Bridge on state highway 26 near Thames will help pave the way for an upgrade to flood protection stopbanks in the area, says Waikato Regional Council.
Localised flooding in the Kirikiri area, exacerbated by the 75-year-old bridge, has caused frequent damage at times.
The new Kirikiri Bridge will be built slightly upstream from the current one. It will be three metres higher than the current one and the design will prevent debris accumulating underneath and contributing to flooding. Work on the bridge is expected to start late next year.
The council’s integrated catchment management (ICM) directorate has been working closely with the NZ Transport Agency in building the business case for the bridge upgrade.
“The design of the current Kirikiri Bridge has limited the standard of flood protection which can be provided by stopbanks under the Waihou Valley Flood Scheme to the local community,” said ICM director Clare Crickett.
“Now with the bridge redevelopment we will be able to look at upgrading the stopbanks in the area to significantly boost the level of protection provided.”
The council plans to work on obtaining resource consents for the stopbank upgrades this year and coordinate the construction of the flood protection works along with the bridge replacement project during 2017-2018.
“This will be the last part of the Waihou Valley flood protection scheme which couldn’t be completed back in 1995 due to the problems with the Kirikiri Bridge,” said Ms Crickett.


Roomfortheriver - Project Roomfortheriver final CRUE ERA-NET report
The link refers to the project Roomfortheriver extended abstract.
The aim of this project was to examine the relative efficiency of non-structural flood mitigation measures. In particular measures which realise the non-structural flood risk mitigation concepts ‘retain the water in the catchment’ and ‘room for the river’ were to be evaluated: Land use change, local retention measures in the landscape through micro ponds and Flood retention along the main stream by providing inundation area.
Three case study areas were selected in the Rambla del Poyo (Spain), Kamp catchment (Austria) and Upper Iller catchment (Austria/Germany), with different climate (semiarid, humid and alpine respectively), hydrological and hydraulic characteristics.

Download the article from Geomechanics and Tunnelling 02/2011.
Manfred Freitag, Markus Larcher, Andreas Blauhut
The Reißeck II pumped storage power station under construction for the Verbund Hydro Power AG is part of their current extension project in southern Austria. Features of the new system are the advantages of the rapidly available and easily controllable power output of a pumped storage scheme in generation operation and the possibility of storing hydropower water at times of low energy demand.
The upgraded output of 430 MW in generation and pumping operation will achieve an increase of efficiency of the entire plant of up to 40 %. It is advantageous that some essential parts of the existing system (reservoir, tunnel system, infrastructure) can be made use of and will not have to be newly constructed. Starting from the experience of the challenging geological conditions during the construction of the original system, extensive geological investigations were carried out. Both mechanical and conventional tunnelling methods are being used to overcome the height difference of just under 600 m. The wholly underground power station with a tunnel system about 5.3 km long and a powerhouse cavern for two machine sets is planned for full operation in September 2014.


CJ Strike Dam - Grand View, Idaho
CJ Strike Dam is owned and maintained by Idaho Power Company. JC Constructors rehabilitated the exiting dam spillway by removing deteriorated concrete and replacing it with structurally sound reinforced concrete. The work was completed during the low flow period with multiple gate operations. Project costs were $300k.


The Indus River has been successfully redirected to a tunnel at the Dasu Hydro Power Project construction site in the Kohistan district of Khyber Pakhtunkhwa.
According to a spokesperson from WAPDA, work has begun on a temporary dam following the river’s diversion, and the construction of the main dam will start after the temporary one is finished.
WAPDA has indicated that the second diversion tunnel currently under construction is scheduled to be completed by mid-April of this year, and during the high flow season, the water of the Indus River will pass through both diversion tunnels. The spokesperson also noted that the 4,320-megawatt capacity Dasu Hydro Power Project will be completed in two phases.
The Dasu Dam, a significant hydroelectric gravity dam, is currently in the process of construction on the Indus River near Dasu in Kohistan District, Khyber Pakhtunkhwa Province, Pakistan. The project, initiated by Pakistan Water and Power Development Authority (WAPDA), is a vital element of the company’s Water Vision 2025. However, the project faced delays due to funding and land acquisition disputes after beginning in 2017. Work resumed in 2019, with the World Bank contributing $700 million of the $4.2 billion project cost, as the government of Imran Khan decided to proceed ahead with the construction of the project, aiming to reduce Pakistan’s reliance on non-renewable energy.
The dam will be 242 meters (794 feet) tall and will support a 4,320-megawatt hydropower station, built in two stages of 2,160 megawatts each. The power plant is anticipated to commence generating electricity in late 2024, with stage I planned to be completed by early 2025. Water from the reservoir will be channeled to the power station located about 3.5 kilometers (2.2 miles) downstream, with power generation from the first stage scheduled for 2026-27. Due to land acquisition problems, the Covid pandemic, and other factors, WAPDA has reported that the expected completion of Dasu Stage-I Hydropower Project has been pushed to FY 2026-27.


Water level reduced in Phewa Lake to repair damThe dam is being repaired 39 years after it was built.
The water level of Phewa Lake in Pokhara has been reduced by one metre to repair the dam.
The 110-metre dam was built in 1961 with Indian government’s assistance. But in 1974 it was washed away. Four years later, with the support from the United Nations Development Programme, the construction of a new dam began about 100 metres south of where the previous one was located.
Construction was completed in 1982, the dam never received any regular repair.
Kiran Acharya, district head of the Water Resource and Irrigation Development Division Office, Kaski, said water level of the lake was reduced to repair the dam.
“We may lower the water level by one metre more if needed,” said Acharya.
The repair work is expected to be completed in about a month. Rs10 million has been allocated for the work.
Phewa Lake is a major tourist attraction in Pokhara.
Here are some photos of the lake after the water level was reduced.

LEE COUNTY, Fla. -- Just one week after reducing the amount of water flowing from Lake Okeechobee to the Caloosahatchee and St. Lucie Estuaries, the U.S. Army Corps of Engineers will be reducing the flow again.
The Corps announced Thursday that the changes will take effect Friday. The new target flow for the Caloosahatchee Estuary is a seven-day average of 2,000 cubic feet per second as measured at W.P. Franklin Lock & Dam near Fort Myers.
Last Friday, the Corps reduced the average flow from 4,000 cfs to 2,500.
The new target flow for the St. Lucie Estuary is a seven-day average of 650 cfs as measured at St. Lucie Lock near Stuart.
The lake stage is 14.33 feet, down over two feet since it peaked at 16.40 feet on February 8.
“The lake level continues to decrease,” said Lt. Col. Jennifer Reynolds, Jacksonville District Deputy Commander for South Florida. “Even though we reduced flows last week , the recession rate has remained the same mostly due to warm, dry weather which is increasing evaporation off the lake and increasing the need for water supply to the south.”
For more information on water level and flows data for Lake Okeechobee, visit the Corps’ water management website.

The Karuma hydropower project is a 600MW run-of-the-river power plant under construction on the Nile River, in Kyandongo District, Uganda.
Estimated to cost $1.7bn, the hydroelectric project is being jointly developed by Uganda’s Ministry of Energy and Mineral Development (MEMD) and Uganda Electricity Generation Company Limited (UEGCL), with the help of Chinese funding.
The project broke ground in August 2013 and is scheduled to commence operation in July 2019.
Karuma will be the biggest power generation facility in Uganda, upon completion, while the Karuma dam will be the largest dam in East Africa.
Karuma hydroelectric plant will represent a significant addition to Uganda’s national grid, as the country’s total electricity generation capacity currently stands at 950MW.
Karuma hydropower project location
The project is located at Karuma Falls, approximately 110km downstream of Lake Kyoga, along the Kampala-Gulu highway, 270km from Uganda’s capital Kampala.
Karuma hydropower project development history
Karuma was originally planned to be developed as a 200MW hydroelectric plant by Norpak, a Norwegian energy company, which acquired exclusive rights to develop the project in 1996.
Norpak, however, pulled out of the project in 2008, alleging lack of support from the World Bank and the Ugandan Government.
The Ugandan government subsequently decided to develop the project with a higher capacity of 600MW, after feasibility studies in 2010 confirmed the adequacy of water flow at Karuma Falls to generate potentially more electricity.
The 600MW project took off in 2013, with Sinohydro roping in as the engineering, procurement and construction (EPC) contractor.
The parliament of Uganda approved the government’s request to borrow foreign funds for the construction of the Karuma hydropower plant, in March 2015.
Karuma hydropower project financing
The $1.7bn project is financed 85% through a soft loan from the Export Import (Exim) Bank of China, while the Ugandan government provides the remaining 15%.
The loan amount will be repaid over a period of 25 years, at an average interest rate of 3%.
Karuma hydropower plant make-up
Karuma hydroelectric power station consists of a 20m-high and 312m-long roller compacted concrete (RCC) gravity dam, six 20m-high and 29m-wide water intake towers, six 7.7m diameter and up to 379m-long concrete lined pressure shafts, and a 200m-long, 21.3m-wide and 53m-high underground power house cavern housing six 100MW vertical Francis turbines.
The reservoir for the hydropower plant is 35km-long and occupies an area of 2,737ha. The gross reservoir volume is estimated to be 79.87 million m³.
The design discharge for the hydropower plant will be 1,128m³/s and the turbines of the plant will operate under a gross head of 70m, at a speed of 150 rotations per minute (rpm).
The power generated from the plant will be evacuated from the underground transformer cavern located just above the underground powerhouse. The 200m-long, 18.0m-wide and 14.4m-high transformer cavern will house six 11kV/400kV step-up transformers and will be connected with the powerhouse through 40m-long bus duct tunnel.
The power station is also built with two 314m-long, 21.5m-wide and 50m-high restricted orifice type tailrace surge chambers, from where water will be sent back to the river through two 12.9m diameter horse shoe-shaped tailrace tunnels of approximately 8.6km length.
Electricity transmission from Karuma hydropower plant
The electricity generated by the plant will be fed into the national grid through three transmission lines, which include the 248km-long 400kV Karuma-Kawanda line, the 55km-long Karuma-Olwiyo line, and the 80km-long Karuma-Lira transmission line.
The project also involves the construction of three new substations at Karuma, Kawanda and Olwiyo, by Uganda Electricity Transmission Company (UETCL).
Contractors involved with Karuma hydropower project
Sinohydro was awarded the engineering, procurement and construction (EPC) contract worth $1.65bn, for the Karuma hydropower project, in September 2013.
Alstom (now GE) was awarded a contract worth $65m by Sinohydro in October 2015, to supply six 100MW Francis turbine-generator sets and related equipment for the Karuma hydropower facility.
Shandong Taikai Transformer, a wholly-owned subsidiary of China’s Taikai Group, was contracted to supply the transformers for the power plant.
AF-Consult Switzerland was appointed as the project management consultant for the Karuma hydropower project in January 2016.
Energy Infratech, an engineering consulting company based in India, was selected as the owner’s engineer for the project.
Energy Infratech had also carried out the feasibility study for the 600MW Karuma hydropower project.
