Chelan County PUD
The Chelan County Public Utility District, or Chelan County PUD, provides electric, water, wastewater public utility and telecommunications services in Chelan County, in north-central Washington in the United States. It is organized under state statute as a nonprofit municipal corporation and functions as a customer-owned public co-operative energy district. It is governed by a Board of Commissioners elected by the customer-owners, who, as owners, receive dividends (in the form of reduced rates) based on the income of the District. History and operations Established in 1936, the PUD began providing electric service in 1947. Today the PUD operates electric, water, and wastewater utilities. The electric portion of the utility includes electric generating stations and distribution facilities. Under its charter, the District is authorized to purchase electric energy; sell electric energy at wholesale and retail prices; acquire, construct and operate electric generating plants an ...

Diesel Generator
A diesel generator (DG) (also known as a diesel genset) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. This is a specific case of an engine generator. A diesel compression-ignition engine is usually designed to run on diesel fuel, but some types are adapted for other liquid fuels or natural gas (CNG). Diesel generating sets are used in places without connection to a power grid or as an emergency power supply if the grid fails, as well as for more complex applications such as peak-lopping, grid support, and export to the power grid. Diesel generator size is crucial to minimize low load or power shortages. Sizing is complicated by the characteristics of modern electronics, specifically non-linear loads. Its size ranges around 50 MW and above, an open cycle gas turbine is more efficient at full load than an array of diesel engines, and far more compact, with comparable capital costs; but for regular pa ...

Megawatt-hour
A kilowatt-hour ( unit symbol: kW⋅h or kW h; commonly written as kWh) is a non-SI unit of energy equal to 3.6 megajoules (MJ) in SI units, which is the energy delivered by one kilowatt of power for one hour. Kilowatt-hours are a common billing unit for electrical energy supplied by electric utilities. Metric prefixes are used for multiples and submultiples of the basic unit, the watt-hour (3.6 kJ). Definition The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) multiplied by (i.e., sustained for) one hour. The International System of Units (SI) unit of energy meanwhile is the joule (symbol J). Because a watt is by definition one joule per second, and because there are 3,600 seconds in an hour, one kWh equals 3,600 kilojoules or 3.6 MJ."Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.", Barry N. Taylor. (2001 ed.''The International System of Units.'' (Special publication 33 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Work (physics), energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish people, Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own Watt steam engine, steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the vo ...

List Of Lakes By Depth
These articles lists the world's deepest lakes. Lakes ranked by maximum depth ''This list contains all lakes whose maximum depth is reliably known to exceed '' Geologically, the Caspian Sea, like the Black and Mediterranean seas, is a remnant of the ancient Tethys Ocean. The deepest area is oceanic rather than continental crust. However, it is generally regarded by geographers as a large endorheic salt lake. Of these registered lakes; 10 have a deepest point above the sea level. These are: Issyk-Kul, Crater Lake, Quesnel, Sarez, Toba, Tahoe, Kivu, Nahuel Huapi, Van and Poso. Lakes ranked by mean depth Mean depth can be a more useful indicator than maximum depth for many ecological purposes. Unfortunately, accurate mean depth figures are only available for well-studied lakes, as they must be calculated by dividing the lake's volume by its surface area. A reliable volume figure requires a bathymetric survey. Therefore, mean depth figures are not available for many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelan River
The Chelan River is a tributary of the Columbia River, in the U.S. state of Washington. Just long, it is the shortest river in Washington. Lake Chelan Dam is located at the river's source: the outlet of Lake Chelan. Nearly the entire river's flow is diverted to the Lake Chelan Powerhouse, downstream near the river's mouth. Thus the Chelan River is almost always dry. Statistics on the streamflow are taken at the tailrace of the powerhouse, measuring the water that would flow through the river were it not diverted, although not including small tributaries, including Daybreak Canyon, that join the Chelan riverbed from the Lake Chelan Dam to the canal outlet. Course The Chelan River originates at the outlet of Lake Chelan, in the city of Chelan at the southern end of the lake. Lake Chelan Dam, also in the city of Chelan, blocks the river. The dry riverbed runs through a steep and rocky gorge, dropping before reaching the Columbia River near the community of Chelan Falls. Only th ...

Lake Chelan
Lake Chelan ( ) is a narrow, long lake in Chelan County, north-central Washington state, U.S. It is an overdeepened lake and resembles a fjord, with an average width of . Near its upper end, the lake surface lies more than below peaks less than away. Before 1927, Lake Chelan was the largest natural lake in the state, in terms of both surface area and water volume. Upon the completion of Lake Chelan Dam in 1927, the elevation of the lake was increased by to its present maximum-capacity elevation of . With a maximum depth of , Lake Chelan is the third deepest lake in the United States behind Crater Lake, the deepest, and Lake Tahoe, the second deepest. Because of overdeepening, the sides of this lake drop steeply to its bottom. The deepest part of Lake Chelan lies as much as below sea level. In places, the bedrock floor of the valley occupied by Lake Chelan, which is buried by Pleistocene glacial and lacustrine sediments, lies at least below sea level. Two communities ...
