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 ...
The unit commitment problem (UC) in electrical power production is a large family of mathematical optimization problems where the production of a set of electrical generators is coordinated in order to achieve some common target, usually either matching the energy demand at minimum cost or maximizing revenue from electricity production.
The cost of a electricity production depends on costs during the expected lifetime of the generator and the amount of electricity the generator is expected to produce over its lifetime. The levelized cost of electricity (LCOE) is the average cost in currency per energy unit, for example, EUR per kilowatt-hour or AUD per megawatt-hour. [3]
Visualisation of Numbeo's 2023 cost of living index by country. The cost of living is the cost of maintaining a certain standard of living for an individual or a household. Changes in the cost of living over time can be measured in a cost-of-living index. Cost of living calculations are also used to compare the cost of maintaining a certain ...
Integrated resource planning (IRP, also least-cost utility planning, LCUP) is a form of least-cost planning used by the public utilities. The goal is to meet the expected long-term growth of demand with minimal cost, using a wide selection of means, from supply-side (increasing production and/or purchasing the supply) to demand-side (reducing the consumption).

The study shows that PHEVs can reduce the CO 2 emissions from the power system if actively integrated, whereas a hands-off approach – letting people charge their cars at will – is likely to result in an increase in emissions. [123] A 2013 study uses Balmorel to examine cost-optimized wind power investments in the Nordic-Germany region.
Power plants that do not change their power output quickly, such as some large coal or nuclear plants, are generally called baseload power plants. [ 3 ] [ 5 ] [ 6 ] In the 20th century most or all of base load demand was met with baseload power plants, [ 7 ] whereas new capacity based around renewables often employs flexible generation.
Curtailment of wind power in western China was around 20% in 2018. [12] In 2018, curtailment in the California grid was 460 GWh, or 0.2% of generation. [13] Curtailment has since increased [7] [14] to 150-300 GWh/month in spring of 2020 and 2021, [15] [16] mainly solar power at noon as part of the duck curve. [17]
