Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a transmission network. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid.
The Federal Energy Regulatory Commission (FERC) is an independent agency of the United States government that regulates the interstate transmission and wholesale sale of electricity and natural gas and regulates the prices of interstate transport of petroleum by pipeline. FERC also reviews proposals to build interstate natural gas pipelines, natural gas storage projects, and liquefied natural gas (LNG) terminals, in addition to licensing non-federal hydropower projects.
The HVDC Inter-Island link is a 610 km (380 mi) long, 1200 MW high-voltage direct current (HVDC) transmission system connecting the electricity networks of the North Island and South Island of New Zealand together. It is commonly referred to as the Cook Strait cable in the media and in press releases, although the link is much longer than its Cook Strait section. The link is owned and operated by state-owned transmission company Transpower New Zealand.
The Kintigh Generating Station, also known as Somerset Operating Co. LLC of the Upstate New York Power Producers was a 675-megawatt coal-fired power plant located in Somerset, New York, United States. The plant was owned by AES Corporation until bankruptcy. Its unit was launched into service in 1984. Coal is provided to the plant via the Somerset Railroad. The waste heat is dumped into Lake Ontario, resulting in a warm-water plume visible on satellite images. The plant's 625-foot smoke stack can be seen across Lake Ontario from the shores of Toronto, Pickering, Oshawa, and Ajax, Ontario. It can also be seen from points along the Niagara Escarpment, including Lockport, NY, approximately 20 miles south. Power from the plant is transferred by dual 345kV power lines on wood pylons, which run south from the plant through rural agricultural land. In Royalton, NY they split at their physical junction with the dual circuit 345-kV Niagara-to-Edic transmission line, owned by the New York Power Authority, one circuit heads west to a substation at Niagara Falls, the other heads east to Station 80 south of Rochester. This bulk electric transmission constraint, created by the Somerset plant tie-in and forcing wheeling through 230kV and 345kV transmission lines to the Homer City Coal Plant east of Pittsburgh, PA, and returning to NY at the Watercurry substation outside Elmira, will be resolved through the Empire State Line proposal approved by NY Independent System Operator (NYISO).
Indian Point Energy Center (I.P.E.C.) is a now defunct three-unit nuclear power station located in Buchanan, just south of Peekskill, in Westchester County, New York. It sits on the east bank of the Hudson River, about 36 miles (58 km) north of Midtown Manhattan. The facility permanently ceased power operations on April 30, 2021. Before its closure, the station's two operating reactors generated about 2,000 megawatts (MWe) of electrical power, about 25% of New York City's usage. The station is owned by Holtec International, and consists of three permanently deactivated reactors, Indian Point Units 1, 2, and 3. Units 2 and 3 were Westinghouse pressurized water reactors. Entergy purchased Unit 3 from the New York Power Authority in 2000 and Units 1 and 2 from Consolidated Edison in 2001.
A submarine power cable is a transmission cable for carrying electric power below the surface of the water. These are called "submarine" because they usually carry electric power beneath salt water but it is also possible to use submarine power cables beneath fresh water. Examples of the latter exist that connect the mainland with large islands in the St. Lawrence River.
Long Island Power Authority is a municipal subdivision of the State of New York that owns the electric transmission and electric distribution system serving all of Long Island and a portion of New York City known as the Rockaways. LIPA was originally created under the Long Island Power Act of 1985 to acquire the Long Island Lighting Company (LILCO)'s electric and natural gas infrastructure after the cancellation of the Shoreham Nuclear Power Plant. LIPA acquired LILCO's transmission system in May 1998, while the remainder of LILCO's natural gas-related infrastructure merged with Brooklyn Union Gas to form KeySpan Energy.
Constellation Energy Corporation is an American energy company headquartered in Baltimore, Maryland. The company provides electric power, natural gas, and energy management services. It has approximately two million customers across the continental United States.
A regional transmission organization (RTO) in the United States is an electric power transmission system operator (TSO) that coordinates, controls, and monitors a multi-state electric grid. The transfer of electricity between states is considered interstate commerce, and electric grids spanning multiple states are therefore regulated by the Federal Energy Regulatory Commission (FERC). The voluntary creation of RTOs was initiated by FERC Order No. 2000, issued on December 20, 1999. The purpose of the RTO is to promote economic efficiency, reliability, and non-discriminatory practices while reducing government oversight.
NRG Energy, Inc. is an American energy company, headquartered in Houston, Texas. It was formerly the wholesale arm of Northern States Power Company (NSP), which became Xcel Energy, but became independent in 2000. NRG Energy is involved in energy generation and retail electricity. Their portfolio includes natural gas generation, coal generation, oil generation, nuclear generation, wind generation, utility-scale generation, and distributed solar generation. NRG serves over 7 million retail customers in 24 US states including Texas, Connecticut, Delaware, Illinois, Maryland, Massachusetts, New Jersey, New York, Pennsylvania, Ohio; the District of Columbia, and eight provinces in Canada.
Danskammer Generating Station is located on the shore of the Hudson River in the Town of Newburgh, New York, United States, 0.5 miles (0.8 km) upstream of the larger oil-fired Roseton Generating Station. Danskammer 'units 1 and 2 burn natural gas as a primary fuel, and oil as a backup fuel, whereas units 3 and 4 are exclusively fired with natural gas.
The Neptune Cable is a 500kV and 660 MW high-voltage direct current submarine power cable between Sayreville, New Jersey and New Cassel, New York, on Long Island. It carries 22 percent of Long Island's electricity. It was developed by Anbaric Development Partners.
Atlantic Wind Connection (AWC) was a proposed electrical transmission backbone by Trans-Elect Development Company that could be constructed off the East Coast of the United States to service off-shore wind farms. Google Energy, the investment firm Good Energies, and Japanese trading firm Marubeni announced that they were investing "tens of millions of dollars" in the initial development stage of what could become a $5 billion project. Financing for the project never lined up, reportedly because the low cost of natural gas made large scale offshore wind uncompetitive.
Wind power in New Jersey is in the early stages of development. New Jersey has just six wind turbines, but the state has plans to develop several major offshore wind projects on the continental shelf of the Atlantic Ocean off the southern Jersey Shore. Legislation has been enacted to support the industry through economic incentives and to permit wind turbines on existing piers.
The Newark Energy Center is a 655-megawatt gas fired power plant in Newark, New Jersey. Approved in 2011, with construction beginning in 2012 it began commercial operations in May 2015. It is situated on a 23 acres (9.3 ha) brownfield east of Doremus Avenue next to a Hess oil terminal on the Passaic River. It was originally built as a joint venture between Hess Corporation and Energy Investors Fund, and it was taken over the latter in 2014.
Talen Energy is an independent power producer founded in 2015. It was formed when the competitive power generation business of PPL Corporation was spun off and immediately combined with competitive generation businesses owned by private equity firm Riverstone Holdings. Following these transactions, PPL shareholders owned 65% of Talen's common stock and affiliates of Riverstone owned 35%. As a condition for FERC approval Talen agreed to divest approximately 1,300 megawatts of generating assets in the PJM Interconnection Region to mitigate FERC's competitiveness concerns. On December 6, 2016, Riverstone Holdings completed the purchase of the remaining 65% of Talen's common stock, making it a privately owned company.
The Transmission Owner Transmission Solutions (TOTS) was a group of three electric power bulk transmission projects constructed on the New York bulk transmission system to increase transfer capability between Upstate New York and Downstate New York. The projects were in-service by June 2016. The projects were proposed by a consortium of the state's seven Investor-Owned Utility (IOU) companies in response to a New York State Public Service Commission (NYSPSC) appeal for Indian Point contingency plans in the event that the 2,060-MW Indian Point power facility were to retire. The shutdown of the Indian Point facility has been a policy goal of Governor Andrew Cuomo since before he began his administration in New York in 2011. The TOTS projects are estimated to have costed $240 million to construct. Construction costs were divided between the seven Transco utilities and the New York Power Authority (NYPA). The IOUs are receiving a 10% return on equity for construction of the projects which is being recovered through retail consumer rates approved by the NYSPSC.
Ocean Wind was a proposed utility-scale 2,248 MW offshore wind farm to be located on the Outer Continental Shelf approximately 15 miles (24 km) off the coast of Atlantic City, New Jersey. It was being developed by Ørsted US Offshore Wind in conjunction with Public Service Enterprise Group (PSE&G). Construction and commissioning were planned for the mid-2020s. The closed Oyster Creek Nuclear Generating Station and B.L. England Generating Station would provide transmission points for energy generated by the wind farm.
