  2. Levelized cost of water - Wikipedia

    en.wikipedia.org/wiki/Levelized_cost_of_water

    The levelized cost of water (LCOW or LCW) is the "cost per unit volume of product water produced by a water treatment process or service". It is a measure of efficiency, with lower values representing more efficient methods. LCW can refer to drinking water for human consumption or water for irrigation. [1]

  3. Cost of electricity by source - Wikipedia

    en.wikipedia.org/wiki/Cost_of_electricity_by_source

    The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...

  4. Mains electricity by country - Wikipedia

    en.wikipedia.org/wiki/Mains_electricity_by_country

    Frequency and voltage supplied to most premises by country. Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices.

  5. Mains electricity - Wikipedia

    The company was able to offset the cost of converting the customer's equipment by the resulting saving in distribution conductors cost. This became the model for electrical distribution in Germany and the rest of Europe and the 220 V system became common. North American practice remained with voltages near 110 V for lamps. [19]

  6. Distribution transformer - Wikipedia

    en.wikipedia.org/wiki/Distribution_transformer

    Transformers designed for below-grade installation can be designed for periodic submersion in water. [14] Distribution transformers may include an off-load tap changer, which slightly adjusts the ratio between primary and secondary voltage to bring the customer's voltage within the desired range on long or heavily loaded lines. [citation needed]

  7. Electricity pricing - Wikipedia

    en.wikipedia.org/wiki/Electricity_pricing

    The cost of electricity also differs by the power source. The net present value of the unit-cost of electricity over the lifetime of a generating asset is known as the levelized cost of electricity (LCOE). However, LCOE does not account for the system costs, in particular related to the guarantee of grid stability and power quality, which can ...

  8. Cost breakdown analysis - Wikipedia

    en.wikipedia.org/wiki/Cost_breakdown_analysis

    The cost breakdown analysis is a popular cost reduction strategy and a viable opportunity for businesses. [1] [2] [3] The price of a product or service is defined as cost plus profit, whereas cost can be broken down further into direct cost and indirect cost. [1] As a business has virtually no influence on indirect cost, a cost reduction ...

  9. Electric power distribution - Wikipedia

    en.wikipedia.org/wiki/Electric_power_distribution

    In the first half of the 20th century, in many places the electric power industry was vertically integrated, meaning that one company did generation, transmission, distribution, metering and billing. Starting in the 1970s and 1980s, nations began the process of deregulation and privatization , leading to electricity markets .
