Samina pumped storage scheme
Jäger Bau GmbH has been awarded with the construction of a storage cavern for the existing hydro power plant "Samina" in the city of Vaduz (Principality of Liechtenstein) in 2009. This small power station will be converted to a pumped storage hydro power plant. The start of construction has been delayed remarkably due to extensive environmental compatibility assessments resulting in a commencement of the site installation in October 2011 only.
The excavation of the storage cavern (50.000 m³) has been done by drill & blast method. The adit is right next to the existing head race tunnel requiring utmost caution during the initial blasts. Further special attention had to been taken to a preferably low noise level execution since the site is located within a residential area.


A project to repair the outlet structure of the dam at Haviland Lake has been postponed. The project, which was supposed to start after Labor Day, will be rescheduled for September 2020.
The lake, 20 miles north of Durango, is open for recreation and it will be stocked with rainbow trout next spring.
When the outlet structure area was being inspected in September, state Park and Wildlife officials found a mechanical device used to raise the outlet gate needed to be repaired before the water level of the lake could be lowered safely. That repair will be made later this month.
The dam structure is owned by Parks and Wildlife and the reservoir is part of Haviland Lake State Wildlife Area.

|In the proposed project, it is aimed to perform a high-performance estimation of the river flow general data and the peak flows that occur in the river flow and are very difficult to predict.
For this purpose, it is aimed to develop a method using deep neural networks based on multiple data, including parameters that have not been used before in the literature. In addition, it is aimed to increase the estimation performance by analyzing the sudden peaks in the data with the sudden frequency change by using the Instantaneous Frequency (IF) features, VMD, LMD and Hilbert-Huang methods, which use the decomposition method according to the instantaneous frequency characteristics of the data, which has not been used in the literature before, in the estimation of daily river flow data.
In the estimation of the peak flows, not only the past flow data of the predicted river is used, but also the flow data of the side rivers feeding this river, the lake level data where the river flows, and the meteorological precipitation, temperature, humidity, evaporation and wind speed data are also aimed to be used in the estimation study.
In the project study, which is planned to be realized, studies will be carried out to define, characterize and determine the amount of inter-regional connectivity of the river flow in different regions depending on multiple parameters. The Phase Transfer Entropy (PTE) approach will be used to show the connectivity of the interregional river flow relationship.|
|In this project, a powerful prediction method will be created using advanced signal processing methods and Deep Neural Networks (DNN). Thanks to the model to be developed, a preliminary study will be put forward for the prediction of hydro-meteorological data together with the precise estimation of extreme situations.|

The District is working on securing funding and preparing the project for bidding.


Vice President, Dr. Mahamudu Bawumia, has admitted that the long delay in the construction of the Pwalugu Multipurpose dam project is as a result of financial constraints.
Speaking at the launch of the Northern Development Authority’s five-year strategic plan in Tamale, Dr. Bawumia said government will look for funds to construct the dam.
“Even though the project is facing financial challenges, we are determined to find the resources to complete the construction of the dam.”
Sod was cut for the construction of the Pwalugu Multipurpose dam project in 2020 and was to be funded with a Sydohydro facility of $993 million.
The project awarded to China Power International group was scheduled for completion four years after the sod cutting.
The project was aimed at addressing the perennial flooding associated with the spillage of the Bagre dam from neighbouring Burkina-Faso and also providing 60MW and 50MW of hydro and solar electricity respectively.
But physical construction of the project at Kurugu in the North East Region is yet to commence after two years and ten months into the project execution period.
Last week, peasant farmers in the Northern part of the country demonstrated over the delay in the construction of the dam.

Huge investments in power generation avert crisis
The huge investments in the power sector and increased generation
capacity of the Ceylon Electricity Board (CEB) in the recent past has
averted a power crisis that would been inevitable due to the severe
drought now prevailing, said CEB General Manager Shavindranath Fernando.
He said that water levels of reservoirs in terms of hydro power
generation has reduced to 26 percent.
“The total hydro power capacity of the CEB is 1,257 Gwh and it has
now come down to 328.3 Gwh and is further declining by 4.51 Gwh per day.
No significant rain has been reported in the catchment areas of the
reservoirs. There will be no power cuts and we expect rain to start
soon,” Fernando said.
Water levels of all reservoirs have reduced sharply and the water
level at the Castlereagh reservoir was 15 metres below spill level and
at Mausakele 16 metres below spill level.
The water level in reservoirs in the Mahaweli complex was much lower
and in Victoria it was 33 metres below spill level, Kotmale 20 metres
and Randenigala 10 metres.
The water level of the Samanala reservoir was 21 metres below spill
CEB generation mix last Tuesday was 4.51 Gwh hydro, 31.48 Gwh thermal
(including coal) and 0.32 Gwh wind and the total generation was 36.31
Gwh.Electricity supply depends heavily on thermal power and it accounts
for 86.7 percent of power generation while hydro power is limited to
Wind power accounts for only 0.9 percent. The decline in hydro power
generation is offset by coal power generation of Norochcholai, he said.
The cost of a unit of thermal power is around Rs. 24.00 while for
coal power it is around Rs. 6.50-7.00. The unit cost of hydro power is
around Rs.1.50. He said that the Norochcholai coal power plant is now
functioning at full capacity. Renovation work at the Kukule Ganga power
station has been completed while renovation work at the New Laxapana
tunnel will be completed soon, he said.

P0935 - Hydraulic Pressure Sensor Circuit High
- Faulty Hydraulic Pressure Sensor
- Hydraulic Pressure Sensor harness is open or shorted
- Hydraulic Pressure Sensor circuit poor electrical connection
- Engine Light ON (or Service Engine Soon Warning Light)
Line pressure is electronically controlled by the Transmission Control System (TCM) and is measured by the Line Pressure Sensor (LPS). The desired line pressure is continuously being compared to the actual line pressure and is regulated by electronically changing the duty cycle of the Pressure Control Solenoid (PCS). The Transmission Control System calculates the desired line pressure based on inputs from the transmission and engine. A calculated torque input to the transmission is used as the primary input to the desired line pressure calculation and is called Torque Based Line Pressure. The Transmission Control Module (TCM) monitors the Hydraulic Pressure Sensor. The TCM sets the OBDII code when the Hydraulic Pressure Sensor is not to factory specifications.

Alstom Projects India Ltd has won three major contracts worth over Rs 270 crore (over €40 million) to build hydroelectric projects in the country. The first contract has been signed with Shiga Energy Pvt Ltd for the 97 MW Tashiding hydroelectric project in West Sikkim district on the Rathang Chu river. The second contract has been signed with NSL Tidong Power Generation Pvt Ltd for the Tidong 1 hydroelectric project in Kinnaur District in Himachal Pradesh, consisting of two 50 MW units. The third contract has been signed with Haridwar Infrastructure Pvt Ltd for the Dikchu hydroelectric project on the river Dikchu, a tributary of Teesta River in East Sikkim, for a 96 MW plant.
All equipment will be manufactured at Alstom’s Vadodara facility in Gujarat, one of the company’s largest hydro equipment manufacturing hubs worldwide. Alstom estimates that India has an economically exploitable and viable hydro potential of about 84,000 MW. However, only 19.9 per cent of this potential has been harnessed so far. Additional hydropower capacity would diversify India’s energy mix, currently reliant on fossil fuels, thus contributing to energy security and reducing greenhouse gas emissions.
These three contracts follow a major contract won by Alstom with Tehri Hydro Development Corporation (THDC) to install the 1,000 MW Tehri variable speed pumped storage hydro power plant in Uttarakhand. Alstom projects currently under execution include the 2,000 MW Subansiri Lower hydroelectric power plant in Assam and Arunachal Pradesh, India’s largest hydro project.crackcrack

A Simulation Model for Stage –IV Koyna Hydropower Plant
Mohd. Imran Ahmed, Siraj Y. Abed
Department of Industrial Engineering, King Abdulaziz University,
Hydroelectric power contributes around 12.45 percent of the electricity supply in India. It is considered to be the most vital, unpolluted, emission-free and an inexpensive renewable source of energy. Hydroelectric power-plants operating all over the world aims to have high electric output with minimum maintenance cost. It’s very different with Koyna Hydropower Plant (KHPP) stage IV which generates lower electric output than the installed capacity with higher maintenance. This project aims to build a simulation model which can simulate the regular operation of Koyna Hydropower Plant with Arena®. The study involves to evaluate dynamic response of the system and plant performance under various operating conditions such as head height, quantity of water flow penstock and operating gates. Also to determine and identify the optimum parameters required for maximum power generation. The outcomes of the model helped to analyse the power generation capacity against the required quantity of water flow and head height. The developed simulation model was validated and used as an apparatus to determine the optimal operating parameters that maximise power generation of stage –IV at Koyna Hydropower plant.

The small chamber of the lock at Fischereihafen is currently undergoing comprehensive refurbishment and is therefore closed to shipping.
Renewal of the electromechanical drive systems of Fischereihafen lock began in April. The first construction phase dealt with the outer head of the lock. The present building will be demolished in the course of the modernisation process and the new building will be joined up to the existing flood barrier and close the gap in height. The new electromechanical drive systems will be housed on a flood-proof second level in the building in future. This will prevent flooding of the electric motors and the new gear units on the first level will also be protected against flooding. The refurbishment work will also involve renovation of the upper carriage rails. The second construction phase on the inner head is scheduled for 2023.
The construction work on the small chamber is expected to be concluded by the end of this year and shipping will again be able to pass through the 106.50-metre long and 10.55-metre wide lock without any problems.Refurbishment of the lock is expected to cost approx. EUR 750,000

Granite Reef Diversion Dam (Photo: SRP)
Salt River Project began releasing water from two reservoirs on the Verde River in recent days, sending water flowing into the normally dry Salt River bed in the Phoenix area.
The releases are occurring at the Granite Reef Diversion Dam to make room in the Bartlett Lake and Horseshoe lake reservoirs for additional melting snow into the Verde and Salt rivers watersheds, the result of the heavy snows that occurred late last month, SRP officials said.
Verde River water flows into the Salt River bed as it continues into Phoenix. The Salt River normally is dry through the Valley, with the exception of Tempe Town Lake, where dams hold water in place on the river bed. The downstream dam is designed to allow water to flow through when needed.
The water flow could be seen in areas of the river bed stretching to the Interstate 10 bridge in Phoenix Monday afternoon.
The flow forced the closure of McKellips Road between Alma School Road and Loop 202 freeway north of Mesa, and a portion of Gilbert Road between State Route 87 and Thomas Road.
Further crossings downstream could be impacted in coming days, SRP said.
According to a statement from SPR, Bartlett Lake and Horseshoe lakes will soon be reaching near capacity from snow melt, with only about 35,000 acre-feet of available space between the two lakes as of last Friday.
The total Verde River storage system was at 86 percent of capacity, up from 31 percent in mid-December. Horseshoe Lake was at 91 percent of capacity and Bartlett Lake 83 percent full.
Storage capacity along the Salt River was 59 percent full as of late last week. Roosevelt Lake, which holds about two-thirds of the water SRP stores, was at 51 percent – up from 40 percent on Jan. 1 and an increase of more than 150,000 acre-feet.
Salt River water storage reservoirs also form Apache, Canyon and Saguaro lakes downstream from Roosevelt Lake.

Parker-Davis Project Post 2028 Marketing Initiative
The Parker-Davis Project was formed by consolidating two projects, Parker Dam and Davis Dam, under terms of the Consolidate Parker Dam Power Project and Davis Dam Project Act on May 28, 1954. Davis Dam, on the Colorado River 67 miles below Hoover Dam, created Lake Mohave. Davis Dam has a storage capacity of 1.8 million acre-feet. The five generation units’ operating capacity is 255,000 kilowatts. Parker Dam, which created Lake Havasu 155 miles below Hoover Dam on the Colorado River, was authorized by the Rivers and Harbors Act of Aug. 30, 1935. Reclamation constructed the project partly with funds advanced by the Metropolitan Water District of Southern California. MWD receives half of the capacity and energy from four generating units. The 50% federal share of Parker Power plant capacity, as determined by Reclamation, is 60,000 kW.

If the entire Odisha is battling with continuous power cuts amid rising temperatures these days, it is entirely because of the failure in hydro power generation.The total hydel power generation capacity of the state is 2,099 MW. In contrast, only 556 MW is currently being generated from seven hydel power plants in the state which is only a quarter of the total capacity.Despite the fact that there is no shortage of water in the reservoirs as compared to the water level this time last year, the production has come down.For example, the water level in Burla’s Hirakud reservoir on April 23 last year was 608.73 feet. On the same date, this year the water level of the reservoir was 612.83 feet.
According to energy experts, the present problem is arising because nothing has been done to dig up the reservoirs and increase their water holding capacity.Energy expert Bibhucharan Swain said, “Since the dredging of the reservoirs has not been done for a long time, the water holding capacity of these reservoirs is affecting the power generation.”On the other hand, Water Resources Minister Raghunandan Das said, “In terms of water level in the reservoirs, we are not in a dangerous position as the water level in our reservoirs has not reduced that much. But if the current heatwave continues for a few more days, nothing can be said as to what will happen.”Meanwhile, power generation at NTPC Darlipali Power Station has been affected. Giving the reason for the shortage of coal, the Energy Department said that efforts are on to address the problems of the consumers.


This project consisted of a flood defence barrier approx 1.4 km long protecting over 100 households in the Ballinasloe area. The works involved construction of a reinforced concrete flood defense wall consisting of the installation of steel sheet piles using Movax piling hammer with welded joints & a 600m reinforced concrete pile cap. The remainder of the flood defence barrier was achieved with the construction of an 800m impermeable clay bund. The project included installation of aluminium flood gates & controlled pen-stocks in existing and new chambers, construction of culverts and head walls, construction of drainage system to rear of flood barrier with over pump chambers as well as the construction of V ditches and cleaning of existing field drains in the surrounding area.
This Project involved installing a new precast concrete box culvert consisting of 9 units 2.1m x 1.8m totaling 18m in length. The culvert was laid adjacent to an existing culvert on the R358 station road, Ballinasloe. A road closure and diversion was put in place to facilitate the works which were carried out in two phases in order to maintain pedestrian access for residents. The river was dammed either side of the new culvert location and the water pumped out before excavation works commenced. Sheet piles were driven in order to support sides of the excavation while the culvert foundation base was prepared and units lifted into place with 90 ton hydraulic mobile crane. There was also numerous services contained within the road including a telecoms junction box, 2 x watermains and a foul sewer line all of which had to remain operational and protected during the works.

Province Advises Lake St. Martin Emergency Outlet Channel to Close
August 14, 2015
Manitoba Infrastructure and Transportation’s Hydrologic Forecasting Centre advises closure of the Lake St. Martin emergency outlet channel will begin this week. The targeted water level through the operation of the emergency channel has been reached within the time frame set out in the province’s temporary authorization from the federal government’s Fisheries and Oceans Canada, set to expire Aug. 31.
The channel was reopened last summer following unusually high rainfalls across the prairies in June of 2014.
The Fairford River carries Lake Manitoba waters into Lake Pinemuta and then into Lake St. Martin. The Dauphin River carries Lake St. Martin waters into Lake Winnipeg.
The current level of Lake St. Martin is 801 feet and is expected to drop to 800.1 ft. by freeze-up, within the desired operating range. The Dauphin River flow is 7,200 cubic feet per second (cfs) and is forecast to drop to 5,500 cfs by freeze-up.
The level on Lake Manitoba is 812.5 ft. and is expected to be about 811.8 ft. at freeze-up, within the operating range established by the 2012 Lake Manitoba/Lake St. Martin Regulation Review Committee. Flows on the Fairford River are currently estimated at 9,680 cfs and are expected to drop to about 5,000 cfs at freeze-up.
The emergency outlet channel was built during the 2011 flood to drain flood water from Lake St. Martin and Lake Manitoba. Rock fill will be pushed across the channel entrance to close off the flow of water from Lake St. Martin into the channel. In addition, environmental monitoring will take place during the closure process with continued efforts to minimize effects to local habitat.
A recent funding commitment of $495 million was announced to construct an additional outlet channel from Lake Manitoba to Lake St. Martin, and the conversion and enlargement of the Lake St. Martin emergency outlet channel. This includes the construction of a permanent structure at the start of the Lake St. Martin channel, as well as an enhancement of the outlet channel. The project also involves the construction of a permanently engineered channel with an outlet to Lake Winnipeg, bypassing Dauphin River First Nation. The permanent structure will significantly reduce the economic burden that chronic flooding has had on the Province of Manitoba. The Manitoba government will invest $330 million in the project as part of Manitoba’s $5.5-billion, five-year core infrastructure plan.

Villages of Sarguja will come under submergence of approved dam in Jashpur district
Protest has intensified over the construction site of the Shekharpur Large Reservoir Scheme, an ambitious irrigation project in the Sitapur region. Opening a front against this irrigation project, the people of a dozen villages have submitted a memorandum to the police station in the name of the Governor, Chief Minister, along with the regional MLA and Food Minister Amarjeet Bhagat, demanding construction of a dam at the proposed site instead of the area being surveyed. They say that if the dam is not constructed at the proposed site instead of the surveyed area, then people of a dozen affected villages in the dam will mobilize in protest against it, which will be the responsibility of the administration.
A large reservoir is to be constructed at Shekharpur in Sitapur to provide irrigation facilities to the un-irrigated areas of Jashpur and Surguja districts. The dam is proposed to be constructed after surveying the Ib River at Dhandapani in Jashpur district and the Maini River area of Shekharpur for construction of the dam under this project. It is alleged that instead of conducting the survey here, instead of conducting the survey here, Suri village in Surguja is surveying the Mani river area flowing through Dhondhagav, Shivnathpur, Petla, Thoothama so that the dam can be constructed here.
In fact, Shekharpur is a village in Jashpur district and this is the name of the scheme, under which this dam is proposed to be built on the Maini river flowing through here, but the construction agency is called Thoothiama, Sarhadi village in Sarguja district, 40 km from here. The main river flowing over the place wants to build a dam on the river. With the construction of this dam here, Dhodhagaon Shivnathpur Petla Kerju, Kunmera, Sarga, Gersa Kathbuda, Ara, Ghasidih, Vansipur, Hardisad will come in the Duban region. People will have to bear the pain of displacement.

We recently commenced stormwater works along Marmion Avenue in Kilburn which is one part of a catchment wide solution to reduce flooding. The works are in relation to the proposed link between the Main North Road stormwater drain to the North Arm East open drain located at the western end of Marmion Avenue. Once works are complete, this will provide flood relief for the area surrounding the Main North Road and Grand Junction Road intersection.
This new stormwater drain will increase the capacity of the existing system and divert 70% of the water within the Main North Road drain away from Grand Junction Road to be discharged directly to the North Arm East open channel which will reduce the effects of overland flows and local flooding.
The North Arm East catchment area covers the suburbs of Northfield, Northgate, Lightsview, Clearview, Broadview, Sefton Park, Blair Athol, Enfield, Kilburn, Gepps Cross and Wingfield.
For any questions regarding the project please contact Nick on 8405 6600 or email firstname.lastname@example.org


CONTROL YOUR FLOW

Long-term stability analysis of Messochora Village
The Mesochora Dam is a 150-m tall concrete-face rock-fill dam on the Acheloos River near Messochora in Trikala, Greece. Although the construction of the Dam was completed in January 2001, the reservoir has yet to be filled due to a variety of legal disputes, one of which is the long-term stability of the hillside village of Messochora.
In this project we acted as a consultants of the dam owner and operator (Public Power Corporation) to assess the stability of the natural slope under rapid drawdown conditions, estimate the earthquake-triggered landslide potential of Messochora Village and conclude on the adequacy of proposed remediation actions.

Nigeria with a population of 180 million people has a total installed electricity generation capacity of 8,644 MW. However, the peak generation is much lower at around 4,000 MW. The reasons for the shortfall in generation can be attributed to the inadequate fuel supply to thermal plants which constitute over 80% of the installed capacity, hydro-logical factors for hydro power stations, maintenance outages at power plants and transmission & distribution outages. The Peak demand is forecasted at 12,800 MW. When seen against the available power of less than 4,000 MW, it can be noticed that there is a peak load shortage of more than 8,000 MW. As a result, the available generation capacity is less than one-third of the total peak demand for electricity.
