75-488: North Shore Central School District was formed in 1953 from the smaller Sea Cliff, Glen Head, and Glenwood Landing school districts. The merger was generally opposed by Glenwood Landing residents, who did not want to share the tax revenues from the Glenwood Generating Station , while the other districts were desirous of them. Glenwood Landing Board of Education President William Anderson once explained

150-447: A magnetic field and a conductor creates an electric current . The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal , oil , and natural gas to generate electricity. Low-carbon power sources include nuclear power , and use of renewables such as solar , wind , geothermal , and hydroelectric . In early 1871 Belgian inventor Zénobe Gramme invented

225-429: A mixed-use development including an exhibition hall in the old turbine room. Using the building for new power generation capacity was deemed unfeasible because modern generation equipment was incompatible with the building design. Demolition of the plant raised concern about the financial effects on the local North Shore School District , as the over $ 20 million annual tax payments from the plant provided 20 percent of

300-579: A transformer to step up voltage for long-distance transmission and then stepped it back down for indoor lighting, a more efficient and less expensive system which is similar to modern systems. The war of the currents eventually resolved in favor of AC distribution and utilization, although some DC systems persisted to the end of the 20th century. DC systems with a service radius of a mile (kilometer) or so were necessarily smaller, less efficient of fuel consumption, and more labor-intensive to operate than much larger central AC generating stations. AC systems used

375-432: A $ 2.5 million one-time grant from the state arranged by local state legislators. The site's municipal and school payments in lieu of taxes fell from $ 23.2 million in 2012 to $ 16.6 million in 2015.

450-420: A byproduct of the useful electrical energy produced. The amount of waste heat energy equals or exceeds the amount of energy converted into useful electricity . Gas-fired power plants can achieve as much as 65% conversion efficiency, while coal and oil plants achieve around 30–49%. The waste heat produces a temperature rise in the atmosphere, which is small compared to that produced by greenhouse-gas emissions from

525-458: A controlled deconstruction rather than an implosion or using a wrecking ball . The demolition of Station 2 required the relocation of a peregrine falcon nest from the top of one of the smoke stacks. After demolition and land remediation had been completed, the area was planned to be paved over with asphalt and offered to developers. The three smaller gas-turbine peaking generators built by LILCO in 1967 and 1972 remained in operation, as did

600-427: A generator powerful enough to produce power on a commercial scale for industry. In 1878, a hydroelectric power station was designed and built by William, Lord Armstrong at Cragside , England . It used water from lakes on his estate to power Siemens dynamos . The electricity supplied power to lights, heating, produced hot water, ran an elevator as well as labor-saving devices and farm buildings. In January 1882

675-425: A hydroelectric power station water flows through turbines using hydropower to generate hydroelectricity . Power is captured from the gravitational force of water falling through penstocks to water turbines connected to generators . The amount of power available is a combination of height and water flow. A wide range of Dams may be built to raise the water level, and create a lake for storing water . Hydropower

750-403: A lower reservoir to an upper reservoir. Because the pumping takes place "off peak", electricity is less valuable than at peak times. This less valuable "spare" electricity comes from uncontrolled wind power and base load power plants such as coal, nuclear and geothermal, which still produce power at night even though demand is very low. During daytime peak demand, when electricity prices are high,

825-406: A material that enhances the mixing of the upflowing air and the down-flowing water. In areas with restricted water use, a dry cooling tower or directly air-cooled radiators may be necessary, since the cost or environmental consequences of obtaining make-up water for evaporative cooling would be prohibitive. These coolers have lower efficiency and higher energy consumption to drive fans, compared to

900-425: A permit to further expand the plant with five 50 MW gas turbines, citing air-quality concerns and the effects of the 1970s energy crisis . Town Supervisor John W. Burke at the time noted the board's recognition that "in view of the fuel shortage, construction of gas turbines just seems out of step with the direction being taken by the average consumer, who lowers his thermostat and wears a sweater in his home to reduce

975-569: A pipe containing a heat transfer fluid, such as oil. The heated oil is then used to boil water into steam, which turns a turbine that drives an electrical generator. The central tower type of solar thermal power plant uses hundreds or thousands of mirrors, depending on size, to direct sunlight onto a receiver on top of a tower. The heat is used to produce steam to turn turbines that drive electrical generators. Wind turbines can be used to generate electricity in areas with strong, steady winds, sometimes offshore . Many different designs have been used in

1050-490: A plan to build ten such plants across Long Island to avoid the risk of rolling blackouts in the face of increased demand like those experienced in California the previous year, given strain on the system from a heat wave in 2001 . The pair of turbines produced 79 MW, just under an 80 MW threshold that would have triggered a full regulatory and environmental review. The new turbines were completed by May 2002, and were

1125-592: A power station is nearly the maximum electrical power that the power station can produce. Some power plants are run at almost exactly their rated capacity all the time, as a non-load-following base load power plant , except at times of scheduled or unscheduled maintenance. However, many power plants usually produce much less power than their rated capacity. In some cases a power plant produces much less power than its rated capacity because it uses an intermittent energy source . Operators try to pull maximum available power from such power plants, because their marginal cost

1200-590: A predecessor of the Long Island Lighting Company (LILCO). The extra generating capacity was needed due to a sixfold increase in Long Island's electricity demand from 1910 to 1925. The expansion also reflected LILCO's then-novel philosophy of using few centralized power plants interconnected by transmission lines, rather than many small plants distributed through the region. In 1936 it was described as "the key electric generating plant of

1275-543: A six-story boiler house mainly filled with equipment, topped by six 140-foot smoke stacks (ultimately reaching 265 feet above the floor slab). At the time of its demolition the New York State Office of Parks, Recreation and Historic Preservation determined that it appeared to meet the criteria for listing on the National Register of Historic Places , triggering an alternative use analysis. Given

1350-624: A state of disrepair that there were several proposals to demolish and replace it, but these were consistently defeated by voters. As of 1977, the district had the lowest property tax rate in Nassau County due to the presence of the Glenwood Generating Station. Additions were made to Glen Head School in 1994, to North Shore Middle School in 1990 and 1994, and to North Shore High School in the 1990s. A series of major renovations and additions to all five school buildings

1425-421: A steam turbine. Bioenergy can also be processed through a range of temperatures and pressures in gasification , pyrolysis or torrefaction reactions. Depending on the desired end product, these reactions create more energy-dense products ( syngas , wood pellets , biocoal ) that can then be fed into an accompanying engine to produce electricity at a much lower emission rate when compared with open burning. It

1500-643: A steam turbine. The combination of a "top" cycle and a "bottom" cycle produces higher overall efficiency than either cycle can attain alone. In 2018, Inter RAO UES and State Grid Archived 21 December 2021 at the Wayback Machine planned to build an 8-GW thermal power plant, which's the largest coal-fired power plant construction project in Russia . A prime mover is a machine that converts energy of various forms into energy of motion. Power plants that can be dispatched (scheduled) to provide energy to

1575-495: A system include: Non-dispatchable plants include such sources as wind and solar energy; while their long-term contribution to system energy supply is predictable, on a short-term (daily or hourly) base their energy must be used as available since generation cannot be deferred. Contractual arrangements ("take or pay") with independent power producers or system interconnections to other networks may be effectively non-dispatchable. All thermal power plants produce waste heat energy as

1650-682: A turbine is spun creating energy. This method is being specifically studied by the Norwegian utility Statkraft, which has calculated that up to 25 TWh/yr would be available from this process in Norway. Statkraft has built the world's first prototype osmotic power plant on the Oslo fjord which was opened on 24 November 2009. In January 2014, however, Statkraft announced not to continue this pilot. Biomass energy can be produced from combustion of waste green material to heat water into steam and drive

1725-445: A typical wet, evaporative cooling tower. Power plants can use an air-cooled condenser, traditionally in areas with a limited or expensive water supply. Air-cooled condensers serve the same purpose as a cooling tower (heat dissipation) without using water. They consume additional auxiliary power and thus may have a higher carbon footprint compared to a traditional cooling tower. Electric companies often prefer to use cooling water from

1800-583: A waste water treatment facility for the adjacent operational units, office and warehouse space, and transmission and fiber optic lines. In 1998, as part of a state-brokered deal, LILCO's power generation facilities, including the Glenwood plant, were absorbed into KeySpan Energy , with the public Long Island Power Authority (LIPA) taking over transmission and delivery functions. KeySpan would be acquired by National Grid in 2007. In 2001, LIPA proposed building two mini-turbines at Glenwood Landing as part of

1875-487: A wide range of frequencies depending on the type of load; lighting load using higher frequencies, and traction systems and heavy motor load systems preferring lower frequencies. The economics of central station generation improved greatly when unified light and power systems, operating at a common frequency, were developed. The same generating plant that fed large industrial loads during the day, could feed commuter railway systems during rush hour and then serve lighting load in

1950-540: Is a power station in Glenwood Landing, New York owned by National Grid USA . It is mainly known for being the former site of an architecturally significant 1920s brick power station. That building and an adjacent 1950s station were demolished over the course of 2013 to 2015, due to their obsolescence as well as the excessive cost of safely retaining the building given its poor condition. Four smaller gas turbine peaking generators remain in operation, as does

2025-583: Is possible to store energy and produce electrical power at a later time as in pumped-storage hydroelectricity , thermal energy storage , flywheel energy storage , battery storage power station and so on. The world's largest form of storage for excess electricity, pumped-storage is a reversible hydroelectric plant. They are a net consumer of energy but provide storage for any source of electricity, effectively smoothing peaks and troughs in electricity supply and demand. Pumped storage plants typically use "spare" electricity during off peak periods to pump water from

2100-518: Is practically zero, but the available power varies widely—in particular, it may be zero during heavy storms at night. In some cases operators deliberately produce less power for economic reasons. The cost of fuel to run a load following power plant may be relatively high, and the cost of fuel to run a peaking power plant is even higher—they have relatively high marginal costs. Operators keep power plants turned off ("operational reserve") or running at minimum fuel consumption ("spinning reserve") most of

2175-465: 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. Solar energy can be turned into electricity either directly in solar cells , or in a concentrating solar power plant by focusing

2250-410: Is used intermittently (peak load). Steam turbines generally operate at higher efficiency when operated at full capacity. Besides use of reject heat for process or district heating, one way to improve overall efficiency of a power plant is to combine two different thermodynamic cycles in a combined cycle plant. Most commonly, exhaust gases from a gas turbine are used to generate steam for a boiler and

2325-760: The Roscoe Wind Farm is the largest onshore wind farm in the world, producing 8000  MW of power, followed by the Zhang Jiakou (3000 MW). As of January 2022, the Hornsea Wind Farm in United Kingdom is the largest offshore wind farm in the world at 1218 MW, followed by Walney Wind Farm in United Kingdom at 1026 MW. In 2021, the worldwide installed capacity of power plants increased by 347 GW. Solar and wind power plant capacities rose by 80% in one year.  As of 2022 ,

2400-526: The Y-50 Cable connection across Long Island Sound . Station 2 was constructed in the 1920s and was considered significant as an example of early 20th-century industrial architecture. It was designed in an industrial Beaux-Arts style, with large arched windows and stringcourse intended to prevent it from becoming an eyesore given its proximity to affluent communities. It was constructed with Flemish bond brickwork and decorative limestone elements. It

2475-488: The largest photovoltaic (PV) power plants in the world are led by Bhadla Solar Park in India, rated at 2245 MW. Solar thermal power stations in the U.S. have the following output: Large coal-fired, nuclear, and hydroelectric power stations can generate hundreds of megawatts to multiple gigawatts. Some examples: Gas turbine power plants can generate tens to hundreds of megawatts. Some examples: The rated capacity of

2550-439: The second law of thermodynamics ; therefore, there is always heat lost to the environment. If this loss is employed as useful heat, for industrial processes or district heating , the power plant is referred to as a cogeneration power plant or CHP (combined heat-and-power) plant. In countries where district heating is common, there are dedicated heat plants called heat-only boiler stations . An important class of power stations in

2625-490: The 20th century central stations became larger, using higher steam pressures to provide greater efficiency, and relying on interconnections of multiple generating stations to improve reliability and cost. High-voltage AC transmission allowed hydroelectric power to be conveniently moved from distant waterfalls to city markets. The advent of the steam turbine in central station service, around 1906, allowed great expansion of generating capacity. Generators were no longer limited by

2700-572: The Drakensberg, Ingula Pumped Storage Scheme . The power generated by a power station is measured in multiples of the watt , typically megawatts (10 watts) or gigawatts (10 watts). Power stations vary greatly in capacity depending on the type of power plant and on historical, geographical and economic factors. The following examples offer a sense of the scale. Many of the largest operational onshore wind farms are located in China. As of 2022,

2775-560: The Kissam Lane School incorporated into the new building. It opened in 1961. The construction of North Shore High School was delayed by a lawsuit by Glenwood Landing residents who wanted to undo the district centralization, but it opened in 1957; it, too, was designed by Vincent Kling. An addition was made to the Glenwood Landing School in 1965. In the 1970s, Sea Cliff School was considered to be in such

2850-860: The Long Island system," and its control room managed LILCO's entire system. In 1939 it was upgraded to burn both coal and oil, and in 1946 natural gas capability was added. In 1942, a 3-hour power outage caused by testing of new distribution circuits affected seven major factories producing material for World War II . These included the Grumman plant in Bethpage and the Republic Aviation plant in Farmingdale , where workers staged an impromptu baseball game while they waited for power to return. Local hospitals and Mitchel Field were able to continue operating under auxiliary power. Although sabotage

2925-493: The Middle East uses by-product heat for the desalination of water. The efficiency of a thermal power cycle is limited by the maximum working fluid temperature produced. The efficiency is not directly a function of the fuel used. For the same steam conditions, coal-, nuclear- and gas power plants all have the same theoretical efficiency. Overall, if a system is on constantly (base load) it will be more efficient than one that

3000-798: The Station 2 building had deteriorated to the point where it was nearing condemnation. In 2011 it was announced that the Glenwood Landing station would be shut down and demolished along with its sister plant in Far Rockaway. The two stations were described as the oldest and least efficient of the power plants on Long Island, with the closures saving $ 76 million through 2015. Local resident Karin Barnaby campaigned to renovate Station 2 for commercial and cultural uses rather than demolish it, pointing to other redeveloped historic power plants in

3075-765: The United States such as the Pratt Street Power Plant in Baltimore and the Homan Square Power House in Chicago . Despite collecting 780 signatures for a petition, this was rejected due to the excessive cost of renovating the building given its poor condition. Demolition was estimated to cost $ 8 million, as opposed to $ 31 million to make the building structurally sound without improving it, and $ 100 million to renovate it into

In thermal power stations, mechanical power is produced by a heat engine that transforms thermal energy , often from combustion of a fuel , into rotational energy. Most thermal power stations produce steam, so they are sometimes called steam power stations. Not all thermal energy can be transformed into mechanical power, according to

3225-484: The amount of fuel burning." Nevertheless, two GE Frame 7B gas turbine generators were constructed that year. In 1978, the Y-50 Cable was constructed between Westchester County 's Dunwoodie North Substation and the Glenwood Generating Station, via the Long Island Sound . The Station 2 generating units were taken out of operation in 1978, but as late as 2009 the building was used for such purposes as

3300-464: The building's poor condition after three decades of disuse, the excessive cost of making the building structurally sound prevented any plans to retain or renovate it. The first facility on the site was Station 1, constructed in 1906 and expanded during World War I , which existed until at least 1939. The Station 2 building was constructed from 1928 to 1931 by the Nassau Power and Light Company,

3375-552: The cooling machinery. These screens are only partially effective and as a result billions of fish and other aquatic organisms are killed by power plants each year. For example, the cooling system at the Indian Point Energy Center in New York kills over a billion fish eggs and larvae annually. A further environmental impact is that aquatic organisms which adapt to the warmer discharge water may be injured if

3450-415: The district was the six-classroom Kissam Lane School in 1956, which would later become North Shore Middle School. Initially a K–3 school, it was designed by Vincent Kling and won national architectural awards for its openness and simple, compact design, with floor-to-ceiling windows and an exterior doorway in every classroom. In 1960, the construction of the junior high school on the site was approved, with

3525-495: The district would thus have to be mitigated by increased taxes on remaining utilities in the district, as well as a $ 2.5 million one-time grant from the state arranged by local state legislators. The site's municipal and school payments in lieu of taxes fell from $ 23.2 million in 2012 to $ 16.6 million in 2015. Station 3 was demolished in November 2013, and demolition of Station 2 was completed in 2015. National Grid opted for

3600-415: The district's budget. This led to fears of a 15–19% increase in residential taxes in late 2014. However, it was determined that according to state law there could be no more than a 1% increase in property taxes for a given tax class as a result of a decreased tax assessment in another class (the four tax classes being residential, cooperatives/condominiums, commercial, and utilities). The financial effects on

3675-562: The eighth largest power generation facility on Long Island. That year it generated 107.7 GWh , which placed twelfth. Power station A power station , also referred to as a power plant and sometimes generating station or generating plant , is an industrial facility for the generation of electric power . Power stations are generally connected to an electrical grid . Many power stations contain one or more generators , rotating machine that converts mechanical power into three-phase electric power . The relative motion between

3750-411: The energy carried by ocean waves , tides , salinity , and ocean temperature differences . The movement of water in the world's oceans creates a vast store of kinetic energy , or energy in motion. This energy can be harnessed to generate electricity to power homes, transport and industries. The term marine energy encompasses both wave power —power from surface waves, and tidal power —obtained from

3825-409: The evening, thus improving the system load factor and reducing the cost of electrical energy overall. Many exceptions existed, generating stations were dedicated to power or light by the choice of frequency, and rotating frequency changers and rotating converters were particularly common to feed electric railway systems from the general lighting and power network. Throughout the first few decades of

3900-423: The first of the ten to enter operation. Station 3's utilization decreased from 43 percent in 2001 to 11.2 percent in 2005. As of 2009, the power station was used as a peaking power plant operating in the summer, with two operational natural gas steam-electric generating units with a combined 210 MW capacity. It had a once-through water cooling system using water from the adjacent Hempstead Harbor . By 2014

3975-406: The kinetic energy of large bodies of moving water. Offshore wind power is not a form of marine energy, as wind power is derived from the wind , even if the wind turbines are placed over water. The oceans have a tremendous amount of energy and are close to many if not most concentrated populations. Ocean energy has the potential of providing a substantial amount of new renewable energy around

4050-425: The light to run a heat engine. A solar photovoltaic power plant converts sunlight into direct current electricity using the photoelectric effect . Inverters change the direct current into alternating current for connection to the electrical grid. This type of plant does not use rotating machines for energy conversion. Solar thermal power plants use either parabolic troughs or heliostats to direct sunlight onto

4125-662: The numbering scheme of the time. At the time of centralization Glenwood Landing School was considered preferable because of its facilities and staff. The Sea Cliff School, which had been built in 1912 and expanded in 1926, was a K–12 school prior to centralization. Glen Head School had been built in 1924. Glenwood Landing School's "Old Building" had been built in 1927 and its "New Building" in 1949. The Glenwood Landing and Glen Head Schools did not provide high school education, and their students attended high school in Sea Cliff, Glen Cove , or Roslyn . The first new building opened by

4200-479: The ocean or a lake, river, or cooling pond instead of a cooling tower. This single pass or once-through cooling system can save the cost of a cooling tower and may have lower energy costs for pumping cooling water through the plant's heat exchangers . However, the waste heat can cause thermal pollution as the water is discharged. Power plants using natural bodies of water for cooling are designed with mechanisms such as fish screens , to limit intake of organisms into

4275-557: The past, but almost all modern turbines being produced today use a three-bladed, upwind design. Grid-connected wind turbines now being built are much larger than the units installed during the 1970s. They thus produce power more cheaply and reliably than earlier models. With larger turbines (on the order of one megawatt), the blades move more slowly than older, smaller, units, which makes them less visually distracting and safer for birds. Marine energy or marine power (also sometimes referred to as ocean energy or ocean power ) refers to

4350-674: The plant shuts down in cold weather . Water consumption by power stations is a developing issue. In recent years, recycled wastewater, or grey water , has been used in cooling towers. The Calpine Riverside and the Calpine Fox power stations in Wisconsin as well as the Calpine Mankato power station in Minnesota are among these facilities. Power stations can generate electrical energy from renewable energy sources. In

4425-406: The power themselves, in which case the generation output is classified into gross generation , and net generation . Gross generation or gross electric output is the total amount of electricity generated by a power plant over a specific period of time. It is measured at the generating terminal and is measured in kilowatt-hours (kW·h), megawatt-hours (MW·h), gigawatt-hours (GW·h) or for

4500-559: The power transmission of belts or the relatively slow speed of reciprocating engines, and could grow to enormous sizes. For example, Sebastian Ziani de Ferranti planned what would have reciprocating steam engine ever built for a proposed new central station, but scrapped the plans when turbines became available in the necessary size. Building power systems out of central stations required combinations of engineering skill and financial acumen in equal measure. Pioneers of central station generation include George Westinghouse and Samuel Insull in

4575-728: The road, which was the monopoly of the gas companies. The customers included the City Temple and the Old Bailey . Another important customer was the Telegraph Office of the General Post Office , but this could not be reached through the culverts. Johnson arranged for the supply cable to be run overhead, via Holborn Tavern and Newgate . In September 1882 in New York, the Pearl Street Station

4650-777: The same power plant. Natural draft wet cooling towers at many nuclear power plants and large fossil-fuel-fired power plants use large hyperboloid chimney -like structures (as seen in the image at the right) that release the waste heat to the ambient atmosphere by the evaporation of water. However, the mechanical induced-draft or forced-draft wet cooling towers in many large thermal power plants, nuclear power plants, fossil-fired power plants, petroleum refineries , petrochemical plants , geothermal , biomass and waste-to-energy plants use fans to provide air movement upward through down coming water and are not hyperboloid chimney-like structures. The induced or forced-draft cooling towers are typically rectangular, box-like structures filled with

4725-436: The situation as "we endure the smoke, let's have the gravy." An earlier vote that year on consolidating the districts failed because that process required the vote to succeed in all three districts individually, while the centralization process only required a simple majority across all voters. It was the first central school district in Nassau County, and was accordingly referred to as "Central School District No. 1" under

4800-512: The storage is used for peaking power , where water in the upper reservoir is allowed to flow back to a lower reservoir through a turbine and generator. Unlike coal power stations, which can take more than 12 hours to start up from cold, a hydroelectric generator can be brought into service in a few minutes, ideal to meet a peak load demand. Two substantial pumped storage schemes are in South Africa, Palmiet Pumped Storage Scheme and another in

4875-448: The time. Operators feed more fuel into load following power plants only when the demand rises above what lower-cost plants (i.e., intermittent and base load plants) can produce, and then feed more fuel into peaking power plants only when the demand rises faster than the load following power plants can follow. Not all of the generated power of a plant is necessarily delivered into a distribution system. Power plants typically also use some of

4950-588: The two constructed in 2002. In addition, three electrical substations , three fuel tanks, and a water tower elsewhere on the site remained in operation. In 2017, National Grid proposed raising the legal power output limit of the two 2002 peaking plants from 79.9 MW to 94 megawatts. In 2020, the 15 MW generator from 1967 was shuttered, leaving four more operational, and the two 1972 generators had water injection systems installed, to comply with stricter air emissions regulations. As of 2020, Glenwood Generating Station's remaining 232 MW nameplate capacity made it

5025-565: The world's first public coal-fired power station , the Edison Electric Light Station , was built in London, a project of Thomas Edison organized by Edward Johnson . A Babcock & Wilcox boiler powered a 93 kW (125 horsepower) steam engine that drove a 27-tonne (27-long-ton) generator. This supplied electricity to premises in the area that could be reached through the culverts of the viaduct without digging up

5100-415: The world. Salinity gradient energy is called pressure-retarded osmosis. In this method, seawater is pumped into a pressure chamber that is at a pressure lower than the difference between the pressures of saline water and fresh water. Freshwater is also pumped into the pressure chamber through a membrane, which increases both the volume and pressure of the chamber. As the pressure differences are compensated,

5175-458: Was also constructed to minimize noise and ash pollution. Buildings with such architectural detail were usually found in urban areas, making the Glenwood plant unusual for being far from urban areas at the time of its construction. The building was divided into three sections: a narrow four-story administration section to the north containing offices; a five-story turbine room containing a large open space with decorated glazed buff brick walls; and

5250-419: Was determined that according to state law there could be no more than a 1% increase in property taxes for a given tax class as a result of a decreased tax assessment in another class (the four tax classes being residential, cooperatives/condominiums, commercial, and utilities). The financial effects on the district would thus have to be mitigated by increased taxes on remaining utilities in the district, as well as

5325-454: Was established by Edison to provide electric lighting in the lower Manhattan Island area. The station ran until destroyed by fire in 1890. The station used reciprocating steam engines to turn direct-current generators. Because of the DC distribution, the service area was small, limited by voltage drop in the feeders. In 1886 George Westinghouse began building an alternating current system that used

5400-456: Was expanded. A more minor round of renovations to district buildings occurred in 2014. The Glenwood Generating Plant was decommissioned and demolished during 2012–2015. Its demolition raised concern about the financial effects on North Shore School District, as the over $ 20 million annual tax payments from the plant provided 20 percent of the district's budget. This led to fears of a 15–19% increase in residential taxes in late 2014. However, it
