Small hydro is the development of hydroelectric power on a scale suitable for local community and industry, or to contribute to distributed generation in a regional electricity grid. Exact definitions vary, but a "small hydro" project is less than 50 megawatts (MW), and can be further subdivide by scale into "mini" (<1MW), "micro" (<100 kW), "pico" (<10 kW). In contrast many hydroelectric projects are of enormous size, such as the generating plant at the Three Gorges Dam at 22,500 megawatts or the vast multiple projects of the Tennessee Valley Authority.
The Jhelum River is a river in the northern Indian subcontinent. It originates at Verinag and flows through the Indian-administered territory of Jammu and Kashmir, into Pakistani-administered Azad Kashmir, then the Pakistani province of Punjab. It is the westernmost of the five rivers of the Punjab region, and flows through the Kashmir Valley. It is a tributary of the Chenab River and has a total length of about 725 kilometres (450 mi).
India is the third largest producer of electricity in the world. During the fiscal year (FY) 2022–23, the total electricity generation in the country was 1,844 TWh, of which 1,618 TWh was generated by utilities.
Power Grid Corporation of India Limited is an Indian central public sector undertaking under the ownership of the Ministry of Power, Government of India. It is engaged mainly in transmission of bulk power across different states of India. It is headquartered in Gurugram. Power Grid transmits about 50% of the total power generated in India on its transmission network.
Salal Dam, also known as Salal Hydroelectric Power Station, is a run-of-the-river hydropower project on the Chenab River in the Reasi district of the Jammu and Kashmir. It was the first hydropower project built by India in Jammu and Kashmir under the Indus Water Treaty regime. After having reached a bilateral agreement with Pakistan in 1978, with significant concessions made to Pakistan in the design of the dam, reducing its height, eliminating operating pool, and plugging the under-sluices meant for sediment management, India completed the project in 1987. The concessions made in the interest of bilateralism damaged the long-term sustainability of the dam, which silted up in five years. It currently runs at 57% capacity factor. Its long-term future is uncertain.
In Honduras, there is an important potential of untapped indigenous renewable energy resources. Due to the variability of high oil prices and declining renewable infrastructure costs, such resources could be developed at competitive prices.
Dul Hasti is a 390 MW hydroelectric power plant in Kishtwar district of Jammu and Kashmir, India built by NHPC. The power plant is a run-of-the-river type on the Chenab River, in a rugged, mountainous section of the Himalayas, and several hundred kilometers from larger cities in the Jammu Division. It consists of a 70 m (230 ft) tall gravity dam which diverts water through a 9.5 km (5.9 mi) long headrace tunnel to the power station which discharges back into the Chenab. The project provides peaking power to the Northern Grid with beneficiary states being Jammu and Kashmir, Punjab, Haryana, Uttar Pradesh, Uttarakhand, Rajasthan, Delhi and Union Territory of Chandigarh. It was constructed between 1985 and 2007.
Uri Dam is a 480 MW hydroelectric power station on the Jhelum River near Uri in Baramula district of the Jammu and Kashmir, India. It is located very near to the Line of Control, the de facto border between India and Pakistan. The station is largely built under a hill with a 10 km tunnel. It is of the run-of-the-river type without a large dam, since the Indus Waters Treaty gives Pakistan the exclusive right to regulate the Jhelum River. On 4 July 2014 a 240 MW Uri-II power project which is a new project located just downstream of Uri I, was inaugurated.
There are almost 200 large dams in Myanmar. Myanmar (Burma) has a large hydroelectric power potential of 39,000 megawatts (52,000,000 hp), although the economical exploitable potential is about 37,000 megawatts (50,000,000 hp). Between 1990 and 2002, the country tripled its installed capacity of hydro plants, increasing from 253 megawatts (339,000 hp) to 745 megawatts (999,000 hp). Total installed capacity in 2010 is at least 2,449 megawatts (3,284,000 hp) MW, 6% of potential. Several large dams are planned to increase future hydro utilization.
India is 5th globally for installed hydroelectric power capacity. As of 31 March 2020, India's installed utility-scale hydroelectric capacity was 46,000 MW, or 12.3% of its total utility power generation capacity. Additional smaller hydroelectric power units with a total capacity of 4,683 MW have been installed. India's hydroelectric power potential is estimated at 148,700 MW at 60% load factor. In the fiscal year 2019–20, the total hydroelectric power generated in India was 156 TWh with an average capacity factor of 38.71%.
NTPC Limited, formerly known as National Thermal Power Corporation, is an Indian central Public Sector Undertaking under the ownership of the Ministry of Power and the Government of India, who is engaged in the generation of electricity and other activities. The headquarters of the PSU are situated at New Delhi. NTPC's core function is the generation and distribution of electricity to State Electricity Boards in India. The body also undertakes consultancy and turnkey project contracts that involve engineering, project management, construction management, and operation and management of power plants.
Energy in Bhutan has been a primary focus of development in the kingdom under its Five-Year Plans. In cooperation with India, Bhutan has undertaken several hydroelectric projects whose output is traded between the countries. Though Bhutan's many hydroelectric plants provide energy far in excess of its needs in the summer, dry winters and increased fuel demand makes the kingdom a marginal net importer of energy from India.
Hindustan Powerprojects Private Ltd. (HPPPL), formerly known as Moser Baer Projects Pvt Ltd, is an electrical power developer in India, started by Ratul Puri. It operates in power generation, power trading, EPC, and development and renewables across thermal, solar, hydro and mining vertical markets. The company holds assets of around ₹ 14,500 crore to date, and is the fastest growing integrated power company in India.
The Ratle Hydroelectric Plant is a run-of-the-river hydroelectric power station, with permitted pondage under the Indus Water Treaty, currently under construction on the Chenab River, downstream of the village near Drabshalla in Kishtwar district of the Indian Union Territory of Jammu and Kashmir. The project includes a 133 m (436 ft) tall gravity dam and two power stations adjacent to one another. Water from the dam will be diverted through four intake tunnels about 400 m (0.25 mi) southwest to the power stations. The main power station will contain four 205 MW Francis turbines and the auxiliary power station will contain one 30 MW Francis turbine. The installed capacity of both power stations will be 850 MW. On 25 June 2013, Prime Minister Manmohan Singh laid the foundation stone for the dam. Pakistan has frequently alleged that it violates the Indus Waters Treaty.
