Hydropower, large and small, remains by far the most important of the " renewable " for electrical power production worldwide. Small-scale hydro is in most cases " run-of-river " , with no dam, and is one of the most cost-effective and environmentally benign energy technologies to be considered both for rural electrification in less developed countries and developed countries for further hydro developments countries(like Ethiopia). This paper addresses power generation for rural applications by means of small hydropower plants by using cross-flow turbine systems .The cross-flow turbine is suitable for installing small hydroelectric power plants in case of low head and flow rate. Using mathematical analysis a complete design of such turbines has been done in this paper. Abstract-Hydropower, large and small, remains by far the most important of the " renewable " for electrical power production worldwide. Small-scale hydro is in most cases " run-of-river " , with no dam, and is one of the most cost-effective and environmentally benign energy technologies to be considered both for rural electrification in less developed countries and developed countries for further hydro developments countries(like Ethiopia). This paper addresses power generation for rural applications by means of small hydropower plants by using cross-flow turbine systems .The cross-flow turbine is suitable for installing small hydroelectric power plants in case of low head and flow rate.

• Downloads:3127 Flat Jack Method for Measuring Design Parameters for Hydraulic Structures of the Koyna Hydro Electric Project in India Keshav Ral Dhawan, Chief Research Officer, Central Water & Power Research Station, Khadakwasla, Pune– 411 024; [email protected] ABSTRACT: The paper presents two different projects: The first involves a case with limited rock cover on a side of an excavated surge shaft located near a steep slope. The second involves the assessment of design parameters of an existing masonry dam for use as input in dynamic analysis. The induced stresses in the surge shaft of Koyna Hydro Electric Project (K.H.E.P.) stage-IV were measured with flat jack. These tests were first performed in a 4 m diameter pilot shaft and after the shaft was excavated to its full diameter of 22.70 m. The stresses increased from 3.96 MPa to 5.09 MPa, when the 4m- diameter surge shaft was expanded to its full diameter of 22.70 m, in the case where significant rock mass cover existed at EL 651.00 m. However stress reduction or no variation in the induced stress was measured in the portion of insufficient rock cover. In the second case, to determine the design parameters of Kolkewadi masonry dam of K.H.E.P stage-III, flat jack tests were conducted at the upstream side of Kolkewadi masonry dam in masonry of 1:4 and 1:3 and at downstream sloping side in masonry of 1:5. It is impractical and difficult to obtain mechanical properties of masonry in laboratory from the extracted core samples, due to intrinsic nonhomogeneity of the material. [Show full text]

• 6. Water Quality ------61 6.1 Surface Water Quality Observations ------61 6.2 Ground Water Quality Observations ------62 7 Version 2.0 Krishna Basin Preface Optimal management of water resources is the necessity of time in the wake of development and growing need of population of India. The National Water Policy of India (2002) recognizes that development and management of water resources need to be governed by national perspectives in order to develop and conserve the scarce water resources in an integrated and environmentally sound basis. The policy emphasizes the need for effective management of water resources by intensifying research efforts in use of remote sensing technology and developing an information system. In this reference a Memorandum of Understanding (MoU) was signed on December 3, 2008 between the Central Water Commission (CWC) and National Remote Sensing Centre (NRSC), Indian Space Research Organisation (ISRO) to execute the project “Generation of Database and Implementation of Web enabled Water resources Information System in the Country” short named as India-WRIS WebGIS. India-WRIS WebGIS has been developed and is in public domain since December 2010 (www.india- wris.nrsc.gov.in). It provides a ‘Single Window solution’ for all water resources data and information in a standardized national GIS framework and allow users to search, access, visualize, understand and analyze comprehensive and contextual water resources data and information for planning, development and Integrated Water Resources Management (IWRM). Basin is recognized as the ideal and practical unit of water resources management because it allows the holistic understanding of upstream-downstream hydrological interactions and solutions for management for all competing sectors of water demand. The practice of basin planning has developed due to the changing demands on river systems and the changing conditions of rivers by human interventions. [Show full text]

Nishikant V. Kulkarni 25 2. Rahul A. Mane 30 What is hydroelectric power generation? Hydroelectric power generation is the term referring to generation of electricityby hydropower i.e. the production of electrical power through the use of the gravitational force of falling or flowing water.Most hydroelectric stations use either the natural drop of a river, such as a waterfall or rapids, or a dam is built across a river to raise the water level, and provide the drop needed to create a driving force. It is the most widely used form of renewable energy, accounting for 16 percent of global electricity generation – 3,427 terawatt-hours of electricity production in 2010 and is expected to increase about 3.1% each year for the next 25 years. Hydropower is produced in 150 countries, with the Asia-Pacific region generating 32 percent of global hydropower in 2010. China is the largest hydroelectricity producer, with 721 terawatt-hours of production in 2010, representing around 17 percent of domestic electricity use. History of hydroelectric power generation: Hydropower has been used since ancient times to grind flour and perform other tasks. In 1878 the world's first hydroelectric power scheme was developed at Cragside in Northumberland, England by William George Armstrong. It was used to power a single arc lamp in his art gallery. The old Schoelkopf Power Station No. 1 near Niagara Falls in the U.S. side began to produce electricity in 1881. [Show full text]

The dams provide storages to tide over the temporal and spatial variation in rainfall for meeting the year round requirements of drinking water supply, irrigation, hydropower and industries in the country which lead to development of the national economy. Dams have helped immensely in attaining self sufficiency in foodgrain production besides flood control and drought mitigation. The maintenance of these dams in good health is a serious matter, as failure of any dam would result in huge loss of life and property. Thus safety of dams and allied structures is an important issue that needs to be continuously monitored for ensuring public confidence, protection of downstream areas from potential hazard and ensuring continued accrual of benefits from the large national investments.

Patil Department of Civil Engineering Department of Civil Engineering Department of Civil Engineering North Maharashtra University, Jalgaon North Maharashtra University, Jalgaon North Maharashtra University, Jalgaon Maharashtra, India Maharashtra, India Maharashtra, India [email protected] [email protected] [email protected] Abstract – From the last three decades water resource management becomes very special issue due to uncertain pattern of rainfall all over globe and mainly its drastically affects in south Asian parts. Hydroelectricity uses the energy of running water, without minimizing its quantity, to generate electricity. Therefore, all hydroelectric developments, of small or huge size, whether run of the river accumulated storage, fit the concept of renewable energy. Hydroelectric power plants reservoirs offer incomparable operational flexibility, since they can fast respond to fluctuations in the demand for electricity. The free to adjustment, flexibility and storage capacity of hydroelectric power plants becomes efficient and considerably economical in supplement the use of irregular sources of renewable energy. The operation of electricity systems depends on rapid and flexible generation sources to meet peak demands, maintain the system voltage levels, and quickly re-establish supply after a blackout. Energy generated by hydroelectric installations can be injected into the electricity system faster than that of any other energy source. So providing ancillary services to the electricity system, thus maintaining the balance of water supply availability and fulfill that demand by using a new technique as an additional arrangement for continuous power generation via lake tapping.

Click here to navigate to parent product.

Under water lake tapping is a Norwegian technique developed in that country mainly to tap the inland lakes located high up in the mountains below their normal levels for electricity generation and drinking water supply. This technique is even used in sub-sea tunnels for oil and gas activities. In this technique, a shaft is sunk on the fringe of the lake / reservoir to a pre-determined depth from the bottom of which a tunnel is excavated underneath the lake to reach the lake bottom leaving a break-through rock plug which is finally blasted to connect the lake with the pre conceived water conductor system. The blast is designed in such a way that vibrations produced in the adjoining rock mass and the resultant hydro dynamic pressure build up in the system are kept at minimum acceptable levels, thus protecting the adjoining structure well.

This technique has been used for the first time in India as well as Asian in region on Koyna Project. This paper is a case study describing the various aspects from investigations to actual execution of this technique on said project. With the successful lake tapping experiment in this country, there is a technology transfer; thus opening a new avenue for adopting this technique on several other projects involving improved utilization of water from the existing reservoirs.

Koyna Stage IV Hydroelectric Project

Please provide your contact information:.

Our team will reach out to you in some time

The Koyna Hydroelectric Plant, a branch of the Krishna Basin, is a concrete dam 103.2 m above the foundation, built on the Koyna River, in Satara district, Maharashtra state, India. It is the second-largest hydroelectric project in the country and impounds water to generate 1960 MW in four phases. The power plant was established in the year 1966 with the first two phases; Due to the increase in demand, the power plant was expanded with a new stage with a capacity of 1000 MW, called "Stage-IV". The installed capacity of this stage alone is 1000 Mw. This stage is mostly used to cater for the peak hour demands of the electric grid. 

The power plant uses water coming from the Koyna River for phases I, II, and IV. In Phase-IV, water is drawn directly from the reservoir in the Head Race Tunnel of length 4230 m and delivered to the Head Surge Tank.

Encardio-rite was awarded the sub-contract for supply as well as installation of safety monitoring instrumentation for the project in 2010. The instrumentation included:

• Piezometers
• Pressure cells
• Strain meters
• Borehole extensometer - multipoint
• Prism targets
• Total station 
• Portable readout units and datalogger

Hydropower generation is one of the vital components of reservoir operation, especially for a large multi-purpose reservoir. Deriving optimal operational rules for such a large multi-purpose reservoir serving various purposes like irrigation, hydropower and flood control are complex, because of the large dimension of the problem and the complexity is more if the hydropower production is not an incidental. Thus optimizing the operations of a reservoir serving various purposes requires a systematic study. In the present study such a large multi-purpose reservoir, namely, Koyna reservoir operations are optimized for maximizing the hydropower production subject to the condition of satisfying the irrigation demands using a non-linear programming model. The hydropower production from the reservoir is analysed for three different dependable inflow conditions, representing wet, normal and dry years. For each dependable inflow conditions, various scenarios have been analyzed based on the constraints on the releases and the results are compared. The annual power production, combined monthly power production from all the powerhouses, end of month storage levels, evaporation losses and surplus are discussed. From different scenarios, it is observed that more hydropower can be generated for various dependable inflow conditions, if the restrictions on releases are slightly relaxed. The study shows that Koyna dam is having potential to generate more hydropower.

The Koyna dam authorities, owing to the poor storage in dams across Satara district, have proposed cuts in water discharge for both irrigation and power generation.

About koyna dam.

• Location: It is one of the largest dams in the state of Maharashtra and is located at Koyna Nagar in Satara district.
• It is a rubble-concrete dam constructed on the Koyna River.
• The construction of this dam was completed in 1963 and is amongst the chief civil engineering projects built after the independence of India.
• The main purpose of dam is hydroelectricity with some irrigation in neighboring areas.
• Koyna Hydroelectric Project is the largest completed hydroelectric power plant in India, with a total installed capacity of 1,920 MW. 
• The catchment area of the Koyna Dam blocks up the Koyna River and creates the Shivsagar Lake, which is roughly 50 km long.
• The dam plays a vital role in flood control during monsoon season.

Key Facts about Koyna River

• It is a tributary of the Krishna River in the western part of Maharashtra.
• Origin: It rises near Mahabaleshwar, a famous hill station in the Western Ghats. 
• The river is just 100 meters wide and flows slowly.
• Unlike most of the other rivers in Maharashtra, which flow East-West direction, the Koyna River flows in North-South direction.
• The river merges with the Krishna River at Karad in the Satara district of Maharashtra.
• Due to its electricity-generating potential through the Koyna Hydroelectric Project, Koyna River is known as the Life Line of Maharashtra. 

Q1) Which are the main tributaries of Krishna River?

The principal tributaries joining Krishna are the Ghataprabha, the Malaprabha, the Bhima, the Tungabhadra and the Musi.

Koyna Dam: Notes for UPSC

Major dams and reservoirs in India are important for the UPSC civil services exam. It is a part of the Geography/environment and ecology sections of the IAS exam. In this article, you can read about the Koyna Dam, which is one of the largest dams in the state of Maharashtra.

What is the Koyna Dam?

The Koyna Dam is one of the largest dams in Maharashtra, India. It is a rubble-concrete dam constructed on Koyna River which rises in Mahabaleshwar, a hill station in Sahyadri ranges. It is located in Koyna Nagar, Satara district, nestled in the Western Ghats on the state highway between Chiplun and Karad.

What is the purpose behind its construction?

The main purpose of the dam is hydroelectricity with some irrigation in neighbouring areas. Today the Koyna Hydroelectric Project is the largest completed hydroelectric power plant in India having a total installed capacity of 1,920 MW. Due to its electricity generating potential Koyna river is considered as the ‘lifeline of Maharashtra’.

The spillway of the dam is located at the center. It has 6 radial gates. The dam plays a vital role in flood control in the monsoon season. The catchment area dams the Koyna river and forms the Shivsagar Lake which is approximately 50 km (31 mi) in length. It is one of the largest civil engineering projects commissioned after Indian independence. The Koya hydro-electric project is run by the Maharashtra State Electricity Board.
