111-689: The Robert Moses Niagara Hydroelectric Power Station is a hydroelectric power station in Lewiston, New York , near Niagara Falls. Owned and operated by the New York Power Authority (NYPA), the plant diverts water from the Niagara River above Niagara Falls and returns the water into the lower portion of the river near Lake Ontario . It uses 13 generators at an installed capacity of 2,525 MW (3,386,000 hp) with an average annual net generation of 15,897,000 MWh between 2014 and 2023, and
222-687: A capacity factor of 71.9%. Named for New York City planner Robert Moses , the plant was built to replace power production after the Schoellkopf Power Station , a nearby hydroelectric plant, collapsed in 1956. It stands across the river from Sir Adam Beck Hydroelectric Power Stations in Niagara Falls, Ontario , Canada . The land that the Robert Moses Niagara Power Plant occupies has a long history of use. In 1805, Augustus and Peter Porter of Buffalo, New York , purchased
333-503: A grain elevator , a gazebo and a bridge. Objects are usually artistic in nature, or small in scale compared to structures and buildings. Although objects may be movable, they are generally associated with a specific setting or environment. Examples of objects include monuments, sculptures and fountains. Sites are the locations of significant events, which can be prehistoric or historic in nature and represent activities or buildings (standing, ruined, or vanished). When sites are listed, it
444-737: A greenhouse gas . According to the World Commission on Dams report, where the reservoir is large compared to the generating capacity (less than 100 watts per square metre of surface area) and no clearing of the forests in the area was undertaken prior to impoundment of the reservoir, greenhouse gas emissions from the reservoir may be higher than those of a conventional oil-fired thermal generation plant. In boreal reservoirs of Canada and Northern Europe, however, greenhouse gas emissions are typically only 2% to 8% of any kind of conventional fossil-fuel thermal generation. A new class of underwater logging operation that targets drowned forests can mitigate
555-463: A low-head hydro power plant with hydrostatic head of few meters to few tens of meters can be classified either as an SHP or an LHP. The other distinction between SHP and LHP is the degree of the water flow regulation: a typical SHP primarily uses the natural water discharge with very little regulation in comparison to an LHP. Therefore, the term SHP is frequently used as a synonym for the run-of-the-river power plant . The largest power producers in
666-472: A National Register nomination, although historians and historic preservation consultants often are employed for this work. The nomination consists of a standard registration form (NPS 10-900) and contains basic information about a property's physical appearance and the type of significance embodied in the building, structure, object, site, or district. The State Historic Preservation Office (SHPO) receives National Register nominations and provides feedback to
777-421: A flood and fail. Changes in the amount of river flow will correlate with the amount of energy produced by a dam. Lower river flows will reduce the amount of live storage in a reservoir therefore reducing the amount of water that can be used for hydroelectricity. The result of diminished river flow can be power shortages in areas that depend heavily on hydroelectric power. The risk of flow shortage may increase as

There are several other different types of historic preservation associated with the properties of the National Register of Historic Places that cannot be classified as either simple buildings or historic districts. Through the National Park Service, the National Register of Historic Places publishes
999-494: A hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel -powered energy plants. However, when constructed in lowland rainforest areas, where part of the forest is inundated, substantial amounts of greenhouse gases may be emitted. Construction of a hydroelectric complex can have significant environmental impact, principally in loss of arable land and population displacement. They also disrupt
1110-809: A large natural height difference between two waterways, such as a waterfall or mountain lake. A tunnel is constructed to take water from the high reservoir to the generating hall built in a cavern near the lowest point of the water tunnel and a horizontal tailrace taking water away to the lower outlet waterway. A simple formula for approximating electric power production at a hydroelectric station is: P = − η ( m ˙ g Δ h ) = − η ( ( ρ V ˙ ) g Δ h ) {\displaystyle P=-\eta \ ({\dot {m}}g\ \Delta h)=-\eta \ ((\rho {\dot {V}})\ g\ \Delta h)} where Efficiency

Volpe that parklands could have the same protected status as " historic sites ". Listed properties are generally in one of five broad categories, although there are special considerations for other types of properties that in anyone, or into more specialized subcategories. The five general categories for National Register properties are: building, structure, site, district and object. In addition, historic districts consist of contributing and non-contributing properties. Buildings, as defined by

While many hydroelectric projects supply public electricity networks, some are created to serve specific industrial enterprises. Dedicated hydroelectric projects are often built to provide the substantial amounts of electricity needed for aluminium electrolytic plants, for example. The Grand Coulee Dam switched to support Alcoa aluminium in Bellingham, Washington , United States for American World War II airplanes before it
1554-545: A relatively constant water supply. Large hydro dams can control floods, which would otherwise affect people living downstream of the project. Managing dams which are also used for other purposes, such as irrigation , is complicated. In 2021 the IEA called for "robust sustainability standards for all hydropower development with streamlined rules and regulations". Large reservoirs associated with traditional hydroelectric power stations result in submersion of extensive areas upstream of
1665-526: A result of climate change . One study from the Colorado River in the United States suggest that modest climate changes, such as an increase in temperature in 2 degree Celsius resulting in a 10% decline in precipitation, might reduce river run-off by up to 40%. Brazil in particular is vulnerable due to its heavy reliance on hydroelectricity, as increasing temperatures, lower water flow and alterations in
1776-607: A series of bulletins designed to aid in evaluating and applying the criteria for evaluation of different types of properties. Although the criteria are always the same, the manner they are applied may differ slightly, depending upon the type of property involved. The National Register bulletins describe the application of the criteria for aids to navigation, historic battlefields, archaeological sites, aviation properties, cemeteries and burial places, historic designed landscapes , mining sites, post offices, properties associated with significant persons, properties achieving significance within
1887-448: A small TV/radio). Even smaller turbines of 200–300 W may power a few homes in a developing country with a drop of only 1 m (3 ft). A Pico-hydro setup is typically run-of-the-river , meaning that dams are not used, but rather pipes divert some of the flow, drop this down a gradient, and through the turbine before returning it to the stream. An underground power station is generally used at large facilities and makes use of
1998-455: A source of low-cost renewable energy. Alternatively, small hydro projects may be built in isolated areas that would be uneconomic to serve from a grid, or in areas where there is no national electrical distribution network. Since small hydro projects usually have minimal reservoirs and civil construction work, they are seen as having a relatively low environmental impact compared to large hydro. This decreased environmental impact depends strongly on
2109-414: A start-up time of the order of a few minutes. Although battery power is quicker its capacity is tiny compared to hydro. It takes less than 10 minutes to bring most hydro units from cold start-up to full load; this is quicker than nuclear and almost all fossil fuel power. Power generation can also be decreased quickly when there is a surplus power generation. Hence the limited capacity of hydropower units
2220-706: A total capacity of 180.8 MW (242,500 hp). In 1886, the competing Niagara Falls Power Company, owned by the Cataract Construction Company, built the Adams Power Plant . Between 1900 and 1904, the company built the Powerhouse No. 2, bringing its total generators to 21, with a total capacity of 78 MW (105,000 hp). In 1918, World War I led the power companies to merge into the Niagara Falls Power Company. From 1921 to 1924,

Battery storage capacity is not expected to overtake pumped storage during the 2020s. When used as peak power to meet demand, hydroelectricity has a higher value than baseload power and a much higher value compared to intermittent energy sources such as wind and solar. Hydroelectric stations have long economic lives, with some plants still in service after 50–100 years. Operating labor cost

2553-448: Is hydroelectric power on a scale serving a small community or industrial plant. The definition of a small hydro project varies but a generating capacity of up to 10 megawatts (MW) is generally accepted as the upper limit. This may be stretched to 25 MW and 30 MW in Canada and the United States. Small hydro stations may be connected to conventional electrical distribution networks as

The Center features interactive exhibits about hydroelectricity and its history in the Niagara Frontier. Hydroelectricity Hydroelectricity , or hydroelectric power , is electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity , almost 4,210 TWh in 2023, which
2775-627: Is also usually low, as plants are automated and have few personnel on site during normal operation. Where a dam serves multiple purposes, a hydroelectric station may be added with relatively low construction cost, providing a useful revenue stream to offset the costs of dam operation. It has been calculated that the sale of electricity from the Three Gorges Dam will cover the construction costs after 5 to 8 years of full generation. However, some data shows that in most countries large hydropower dams will be too costly and take too long to build to deliver
2886-466: Is highest in the winter when solar energy is at a minimum. Pico hydro is hydroelectric power generation of under 5 kW . It is useful in small, remote communities that require only a small amount of electricity. For example, the 1.1 kW Intermediate Technology Development Group Pico Hydro Project in Kenya supplies 57 homes with very small electric loads (e.g., a couple of lights and a phone charger, or
2997-445: Is initially produced during construction of the project, and some methane is given off annually by reservoirs, hydro has one of the lowest lifecycle greenhouse gas emissions for electricity generation. The low greenhouse gas impact of hydroelectricity is found especially in temperate climates . Greater greenhouse gas emission impacts are found in the tropical regions because the reservoirs of power stations in tropical regions produce
3108-471: Is more than all other renewable sources combined and also more than nuclear power . Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once
3219-462: Is not an energy source, and appears as a negative number in listings. Run-of-the-river hydroelectric stations are those with small or no reservoir capacity, so that only the water coming from upstream is available for generation at that moment, and any oversupply must pass unused. A constant supply of water from a lake or existing reservoir upstream is a significant advantage in choosing sites for run-of-the-river. A tidal power station makes use of
3330-452: Is not generally used to produce base power except for vacating the flood pool or meeting downstream needs. Instead, it can serve as backup for non-hydro generators. The major advantage of conventional hydroelectric dams with reservoirs is their ability to store water at low cost for dispatch later as high value clean electricity. In 2021, the IEA estimated that the "reservoirs of all existing conventional hydropower plants combined can store
3441-410: Is often higher (that is, closer to 1) with larger and more modern turbines. Annual electric energy production depends on the available water supply. In some installations, the water flow rate can vary by a factor of 10:1 over the course of a year. Hydropower is a flexible source of electricity since stations can be ramped up and down very quickly to adapt to changing energy demands. Hydro turbines have

The power extracted from the water depends on the volume and on the difference in height between the source and the water's outflow. This height difference is called the head . A large pipe (the " penstock ") delivers water from the reservoir to the turbine. This method produces electricity to supply high peak demands by moving water between reservoirs at different elevations. At times of low electrical demand,
5439-624: The 1966 act, SHPOs eventually became integral to the process of listing properties on the National Register. The 1980 amendments of the 1966 law further defined the responsibilities of SHPOs concerning the National Register. Several 1992 amendments of the NHPA added a category to the National Register, known as Traditional Cultural Properties: those properties associated with Native American or Hawaiian groups. The National Register of Historic Places has grown considerably from its legislative origins in 1966. In 1986, citizens and groups nominated 3,623 separate properties, sites and districts for inclusion on

Typically, a Memorandum of Agreement (MOA) is created by which the involved parties agree to a particular plan. Many states have laws similar to Section 106. In contrast to conditions relating to a federally designated historic district, municipal ordinances governing local historic districts often restrict certain kinds of changes to properties. Thus, they may protect
8436-399: The excess generation capacity is used to pump water into the higher reservoir, thus providing demand side response . When the demand becomes greater, water is released back into the lower reservoir through a turbine. In 2021 pumped-storage schemes provided almost 85% of the world's 190 GW of grid energy storage and improve the daily capacity factor of the generation system. Pumped storage
8547-511: The forbidding language, these kinds of places are not actually excluded as a rule. For example, the Register lists thousands of churches. There is a misconception that there is a strict rule that a property must be at least 50 years old to be listed in the National Register of Historic Places. In reality, there is no hard rule. John H. Sprinkle Jr., deputy director of the Federal Preservation Institute, stated: [T]his "rule"
8658-418: The forebay, where it then flows through the turbines of the Moses plant back to the main river. This allows water diverted from above Niagara Falls to pass through two sets of turbines, generating electricity both times. This arrangement is an example of pumped-storage hydroelectricity . Engineers copied what had been built by Ontario Hydro, across the river, when a similar system was built during construction of
8769-401: The future. Thus, additions to an MPS can occur over time. The nomination of individual properties in an MPS is accomplished in the same manner as other nominations. The name of the "thematic group" denotes the historical theme of the properties. It is considered the "multiple property listing". Once an individual property or a group of properties is nominated and listed in the National Register,
8880-543: The group of properties to be included in the National Register. The process begins with the multiple property documentation form which acts as a cover document rather than the nomination to the National Register of Historic Places. The purpose of the documentation form is to establish the basis of eligibility for related properties. The information of the multiple property documentation form can be used to nominate and register related historic properties simultaneously, or to establish criteria for properties that may be nominated in
8991-557: The land had dumped underground. A civil lawsuit was filed in the State of New York against the New York Power Authority , Occidental Petroleum , Hooker Chemicals, Bechtel Corporation , and Parsons Brinckerhoff , which was settled out of court in 1999. Subsequent testing near the Lewiston Reservoir near the project still confirms mercury and organic contamination which restricts the consumption of fish. The Niagara Power Visitors Center
9102-492: The largest amount for the region since 1990. Meanwhile, globally, hydropower generation increased by 70 TWh (up 2%) in 2022 and remains the largest renewable energy source, surpassing all other technologies combined. Hydropower has been used since ancient times to grind flour and perform other tasks. In the late 18th century hydraulic power provided the energy source needed for the start of the Industrial Revolution . In
9213-731: The largest, producing 14 GW , but was surpassed in 2008 by the Three Gorges Dam in China at 22.5 GW . Hydroelectricity would eventually supply some countries, including Norway , Democratic Republic of the Congo , Paraguay and Brazil , with over 85% of their electricity. In 2021 the International Energy Agency (IEA) said that more efforts are needed to help limit climate change . Some countries have highly developed their hydropower potential and have very little room for growth: Switzerland produces 88% of its potential and Mexico 80%. In 2022,
9324-475: The last fifty years, rural historic landscapes, traditional cultural properties and vessels and shipwrecks. Properties are not protected in any strict sense by the Federal listing. States and local zoning bodies may or may not choose to protect listed historic places. Indirect protection is possible, by state and local regulations on the development of National Register properties and by tax incentives. By contrast,
9435-609: The late 19th century, the electrical generator was developed and could now be coupled with hydraulics. The growing demand arising from the Industrial Revolution would drive development as well. In 1878, the world's first hydroelectric power scheme was developed at Cragside in Northumberland , England, by William Armstrong . It was used to power a single arc lamp in his art gallery. The old Schoelkopf Power Station No. 1 , US, near Niagara Falls , began to produce electricity in 1881. The first Edison hydroelectric power station,
9546-488: The mid-1700s, French engineer Bernard Forest de Bélidor published Architecture Hydraulique , which described vertical- and horizontal-axis hydraulic machines, and in 1771 Richard Arkwright 's combination of water power , the water frame , and continuous production played a significant part in the development of the factory system, with modern employment practices. In the 1840s, hydraulic power networks were developed to generate and transmit hydro power to end users. By
9657-783: The multiple property documentation form, combined with the individual National Register of Historic Places nomination forms, constitute a multiple property submission. Examples of MPS include the Lee County Multiple Property Submission , the Warehouses in Omaha , the Boundary Markers of the Original District of Columbia and the Illinois Carnegie Libraries . Before the term "Multiple Property Submission"
9768-651: The natural ecology of the river involved, affecting habitats and ecosystems, and siltation and erosion patterns. While dams can ameliorate the risks of flooding, dam failure can be catastrophic. In 2021, global installed hydropower electrical capacity reached almost 1,400 GW, the highest among all renewable energy technologies. Hydroelectricity plays a leading role in countries like Brazil, Norway and China. but there are geographical limits and environmental issues. Tidal power can be used in coastal regions. China added 24 GW in 2022, accounting for nearly three-quarters of global hydropower capacity additions. Europe added 2 GW,
9879-403: The natural falls through the Robert Moses Power Station turbines. The Lewiston Pump-Generating Plant 43°08′33″N 79°01′18″W / 43.14250°N 79.02167°W / 43.14250; -79.02167 ( Lewiston Pump-Generating Plant ) houses 12 electrically powered pump -generators that can generate a combined 240 MW (320,000 hp) when water in the upper reservoir
9990-764: The nine buildings included in the University of Connecticut Historic District in Storrs, Connecticut (listed in 1989, demolished in 2017), and the Terrell Jacobs Circus Winter Quarters in Peru, Indiana (listed in 2012, demolished in 2021). In France , designation of monument historique is similar to NRHP listing. In the French program, however, permanent restrictions are imposed upon designated monuments, for example requiring advance approval for any renovation of
10101-535: The nominating individual or group. After preliminary review, the SHPO sends each nomination to the state's historic review commission, which then recommends whether the State Historic Preservation Officer should send the nomination to the Keeper of the National Register . For any non-Federally owned property, only the State Historic Preservation Officer may officially nominate a property for inclusion in
10212-639: The nomination. Each nomination contains a narrative section that provides a detailed physical description of the property and justifies why it is significant historically with regard either to local, state, or national history. The four National Register of Historic Places criteria are the following: The criteria are applied differently for different types of properties; for instance, maritime properties have application guidelines different from those of buildings. The National Park Service names seven categories of properties that "are not usually considered for" and "ordinarily ... shall not be considered eligible for"
10323-403: The now-defunct Save America's Treasures grants, which apply specifically to properties entered in the Register with national significance or designated as National Historic Landmarks . The NHPA did not distinguish between properties listed in the National Register of Historic Places and those designated as National Historic Landmarks concerning qualification for tax incentives or grants. This
10434-633: The plant site. Generation of hydroelectric power changes the downstream river environment. Water exiting a turbine usually contains very little suspended sediment, which can lead to scouring of river beds and loss of riverbanks. The turbines also will kill large portions of the fauna passing through, for instance 70% of the eel passing a turbine will perish immediately. Since turbine gates are often opened intermittently, rapid or even daily fluctuations in river flow are observed. Drought and seasonal changes in rainfall can severely limit hydropower. Water may also be lost by evaporation. When water flows it has
10545-417: The powerhouse to commercial use. In 1881, his company completed Schoellkopf Power Station No. 1; it would operate until 1904. In 1891, Schoellkopf Power Station No. 2 opened directly in front of the original, in the gorge below the falls, with a higher 210 ft (64 m) drop and capacity of 25 MW (34,000 hp). In 1914 and 1918, the company built Schoellkopf Stations No. 3A and 3B respectively, with
10656-458: The preservation of income-producing historic properties. The National Park Service was given the responsibility to ensure that only rehabilitations that preserved the historic character of a building would qualify for federal tax incentives. A qualifying rehabilitation is one that the NPS deems consistent with the Secretary of the Interior's Standards for Rehabilitation. Properties and sites listed in
10767-758: The properties that were demolished or otherwise destroyed after their listing are the Jobbers Canyon Historic District in Omaha, Nebraska (listed in 1979, demolished in 1989), Pan-Pacific Auditorium in Los Angeles, California (listed in 1978, destroyed in a fire in 1989), Palace Amusements in Asbury Park, New Jersey (listed in 2000, demolished in 2004), The Balinese Room in Galveston, Texas (listed in 1997, destroyed by Hurricane Ike in 2008), seven of
10878-498: The property more than a National Register listing does. The Department of Transportation Act , passed on October 15, 1966, the same day as the National Historic Preservation Act, included provisions that addressed historic preservation. The DOT Act is much more general than Section 106 NHPA in that it refers to properties other than those listed in the Register. The more general language has allowed more properties and parklands to enjoy status as protected areas by this legislation,
10989-419: The pump-generating plant has undergone a $ 460 million modernization that increased the plant's efficiency and service life. During the mid-1980s, the New York Power Authority began an expansion project at the site, known as FERC ( Federal Energy Regulatory Commission ) Project 2216. Soon after, the project was halted due to discovery of hazardous chemicals such as dioxins , which chemical companies which owned
11100-450: The rainfall regime, could reduce total energy production by 7% annually by the end of the century. Lower positive impacts are found in the tropical regions. In lowland rainforest areas, where inundation of a part of the forest is necessary, it has been noted that the reservoirs of power plants produce substantial amounts of methane . This is due to plant material in flooded areas decaying in an anaerobic environment and forming methane,
11211-588: The rehabilitation of the historic structure. The rehabilitation may be of a commercial, industrial, or residential property, for rentals. The tax incentives program is operated by the Federal Historic Preservation Tax Incentives program, which is managed jointly by the National Park Service, individual State Historic Preservation Offices and the Internal Revenue Service . Some property owners may also qualify for grants, like
11322-413: The state of Colorado, for example, does not set any limits on owners of National Register properties. Until 1976, federal tax incentives were virtually non-existent for buildings on the National Register. Before 1976 the federal tax code favored new construction rather than the reuse of existing, sometimes historical, structures. In 1976, the tax code was altered to provide tax incentives that promote
11433-769: The subject of criticism by academics of history and preservation, as well as the public and politicians. A property listed in the National Register, or located within a National Register Historic District , may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. Properties can be nominated in a variety of forms, including individual properties, historic districts and multiple property submissions (MPS). The Register categorizes general listings into one of five types of properties: district, site, structure, building or object. National Register Historic Districts are defined geographical areas consisting of contributing and non-contributing properties. Some properties are added automatically to
11544-418: The use of their property. Some states and municipalities, however, may have laws that become effective when a property is listed in the National Register. If federal money or a federal permitting process is involved, Section 106 of the National Historic Preservation Act of 1966 is invoked. Section 106 requires the federal agency involved to assess the effect of its actions on historic resources. Statutorily,
11655-453: The water in the Lewiston reservoir is converted into electricity at the Lewiston Dam, and then its remaining potential energy is captured by the Moses plant, which is also capturing the potential energy of the water diverted from the river in real-time. The Robert Moses Plant was refurbished in 2006, which required the southbound lanes of the nearby Robert Moses State Parkway to be closed during said repairs. Beginning in 2012 and until 2021,
11766-524: The world are hydroelectric power stations, with some hydroelectric facilities capable of generating more than double the installed capacities of the current largest nuclear power stations . Although no official definition exists for the capacity range of large hydroelectric power stations, facilities from over a few hundred megawatts are generally considered large hydroelectric facilities. Currently, only seven facilities over 10 GW ( 10,000 MW ) are in operation worldwide, see table below. Small hydro
11877-539: The world. The classification of hydropower plants starts with two top-level categories: The classification of a plant as an SHP or LHP is primarily based on its nameplate capacity , the threshold varies by the country, but in any case a plant with the capacity of 50 MW or more is considered an LHP. As an example, for China, SHP power is below 25 MW, for India - below 15 MW, most of Europe - below 10 MW. The SHP and LHP categories are further subdivided into many subcategories that are not mutually exclusive. For example,
11988-573: Was allowed to provide irrigation and power to citizens (in addition to aluminium power) after the war. In Suriname , the Brokopondo Reservoir was constructed to provide electricity for the Alcoa aluminium industry. New Zealand 's Manapouri Power Station was constructed to supply electricity to the aluminium smelter at Tiwai Point . Since hydroelectric dams do not use fuel, power generation does not produce carbon dioxide . While carbon dioxide
12099-626: Was complete in 1961. When it opened in 1961, it was the Western world's largest hydropower facility. The generation facilities were listed on the National Register of Historic Places in 2017. The pump-generating plant in the Lewiston Dam is atypical, in that the dam was constructed not to control the flow of water in a natural river, but to contain a man-made 1,900-acre (770 ha), 22-billion-US-gallon (83,000,000 m) upper reservoir (named
12210-496: Was deliberate, as the authors of the act had learned from experience that distinguishing between categories of significance for such incentives caused the lowest category to become expendable. Essentially, this made the Landmarks a kind of "honor roll" of the most significant properties of the National Register of Historic Places. As of 1999, 982 properties have been removed from the Register, most often due to being destroyed. Among
12321-650: Was introduced in 1984, such listings were known as "Thematic Resources", such as the Operating Passenger Railroad Stations Thematic Resource , or "Multiple Resource Areas". A listing on the National Register of Historic Places is governmental acknowledgment of a historic district, site, building, or property. However, the Register is mostly "an honorary status with some federal financial incentives". The National Register of Historic Places automatically includes all National Historic Landmarks as well as all historic areas administered by
