Run-of-river hydroelectricity ( ROR ) or run-of-the-river hydroelectricity is a type of hydroelectric generation plant whereby little or no water storage is provided. Run-of-the-river power plants may have no water storage at all or a limited amount of storage, in which case the storage reservoir is referred to as pondage . A plant without pondage is subject to seasonal river flows, so the plant will operate as an intermittent energy source . Conventional hydro uses reservoirs , which regulate water for flood control , dispatchable electrical power , and the provision of fresh water for agriculture .
34-624: The Lockport Powerhouse is an American run-of-the-river dam used by the Metropolitan Water Reclamation District of Greater Chicago to control the outflow of the Sanitary and Ship Canal and limit the diversion of water from Lake Michigan into the Des Plaines River . The Chicago Sanitary and Ship Canal reached Lockport, Illinois in the 1890s. As part of this construction, a lock and dam
68-433: A global testing ground for 10–50 MW run-of-river technology . As of March 2010, there were 628 applications pending for new water licences solely for power generation, representing more than 750 potential points of river diversion. In undeveloped areas, new access roads and transmission lines can cause habitat fragmentation , allowing the introduction of invasive species. Run-of-the-river projects strongly depend on

Preliminary Draft Amendment No. 1 to NBC 2005 Part 11 "Approach to Sustainability" was put into circulation a preliminary draft amendment and BIS accepted the feedback from people till 15 March 2013. The Bill was passed on 8 March 2016 by the Rajya Sabha. The new Bill will repeal
204-557: Is a process through which a third-party organization or certification body assesses and verifies that a product meets specific standards, specifications, or regulatory requirements. The primary purpose of product certification is to ensure that a product is safe, reliable, and compliant with the relevant quality and safety standards. It provides consumers with confidence that the product they are purchasing meets established criteria and has been independently tested and evaluated. Product Certifications are to be obtained voluntarily. For, some of
238-417: Is considered an "unfirm" source of power: a run-of-the-river project has little or no capacity for energy storage and so cannot co-ordinate the output of electricity generation to match consumer demand. It thus generates much more power when seasonal river flows are high (spring freshet ), and depending on location, much less during drier summer months or frozen winter months. Depending on location and type,
272-452: Is considered ideal for streams or rivers that can sustain a minimum flow or those regulated by a lake or reservoir upstream. A small dam is usually built to create a headpond ensuring that there is enough water entering the penstock pipes that lead to the turbines , which are at a lower elevation. Projects with pondage, as opposed to those without pondage, can store water for daily load demands. In general, projects divert some or most of
306-560: Is established by the Bureau of Indian Standards Act, 2016 which came into effect on 12 October 2017. The Minister in charge of the Ministry or Department having administrative control of the BIS is the ex-officio President of the BIS. BIS has 500 plus scientific officers working as Certification Officers, Member secretaries of technical committees and lab OIC's . The organisation was formerly
340-501: Is generally used to cover exclusively short-term peak times electricity demand. Diversion Weir is also heavily dependent on the natural river flow. Similar to a regular dam, water is stored from lull periods to be used during peak-times. This allows for the pondage dams to provide for the regulation of daily and/or weekly flows depending on location. When developed with care to footprint size and location, run-of-the-river hydro projects can create sustainable energy minimizing impacts to
374-441: Is rated at 1,853 MW. Some run-of-the-river projects are downstream of other dams and reservoirs. The reservoir was not built by the project but takes advantage of the water supplied by it. An example would be the 1995 1,436 MW La Grande-1 generating station . Previous upstream dams and reservoirs were part of the 1980s James Bay Project . There are also small and somewhat-mobile forms of a run-of-the-river power plants. One example

The energy within the moving water propels a power generator and thereby creates electricity. Prototypes by commercial producers are generating power on the Middle Rhine river in Germany and on the Danube river in Austria. The advantages and disadvantages of run-of-river dams depends on
442-716: The Indian Standards Institution ( ISI ), set up under the Resolution of the Department of Industries and Supplies No. 1 Std.(4)/45, dated 3 September 1946. The ISI was registered under the Societies Registration Act, 1860. A new Bureau of Indian standards (BIS) Act 2016 which was notified on 22 March 2016, has been brought into force with effect from 12 October 2017. The Act establishes the Bureau of Indian Standards (BIS) as
476-915: The disadvantages associated with reservoirs and so cause fewer environmental impacts. The use of the term "run-of-the-river" for power projects varies around the world. Some may consider a project run-of-the-river if power is produced with no water storage, but limited storage is considered run-of-the-river by others. Developers may mislabel a project run-of-the-river to soothe public perception about its environmental or social effects. The European Network of Transmission System Operators for Electricity distinguishes run-of-the-river and pondage hydropower plants, which can hold enough water to allow generation for up to 24 hours (reservoir capacity / generating capacity ≤ 24 hours), from reservoir hydropower plants, which hold far more than 24 hours of generation without pumps. The Bureau of Indian Standards describes run-of-the-river hydroelectricity as: A power station utilizing

The Standard Mark is compulsory for certain types of electronics and IT goods, whereas the ISI mark is mandatory for product categories such as cement, household electrical products, food products, steel materials, etc. The ISI mark is also used for several voluntary BIS certification product categories. Indian importers who intend to get Certification Mark may apply for
816-433: The plant will most likely have a lower head of water than from a dam, and will thus generate less power. The potential power at a site is a result of the head and flow of water. By damming a river, the head is available to generate power at the face of the dam. A dam may create a reservoir hundreds of kilometres long, but in run-of-the-river the head is usually delivered by a canal, pipe or tunnel constructed upstream of
850-442: The power house. The cost of upstream construction makes a steep drop desirable, such as falls or rapids. Small, well-sited run-of-the-river projects can be developed with minimal environmental impacts. Larger projects have more environmental concerns. For fish-bearing rivers, a ladder may be required, and dissolved gases downstream may affect fish. In British Columbia , the mountainous terrain and wealth of big rivers have made it

A second phase of construction occurred from 1922 to 1933 to handle differing water loads following the opening of the Ohio River Standard Navigation Lock . First operational in 1907, the powerhouse is now recognized as the oldest hydroelectric plant in Illinois. The Lockport Lock, Dam and Power House Historic District
1122-789: Was built in Lockport. Seven waste gates, used to control the level of water in the canal and Des Plaines River , were part of this project. From 1903 to 1907, the canal was extended from Lockport to Joliet . Construction on the Lockport Powerhouse began as part of this extension in 1905. Designed by Frederick L. Barrett, the red-roofed Beaux Arts powerhouse was constructed with concrete blocks coursed to resemble stone. The powerhouse featured four Francis-style turbines to generate electrical power, capable of generating 40,000 horsepower (30,000 kW). These turbines have since been replaced with two vertical Kaplan turbines . The powerhouse
