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 system of plug types using a single letter (from A to O) used here is from World Plugs, which defines the plug type letters in terms of a general description, without making reference to specific standards. Where a plug does not have a specific letter code assigned to it, then it may be defined by the style sheet number listed in IEC TR 60083.
Mains electricity, utility power, grid power, domestic power, wall power, household current, [2] or, in some parts of Canada, hydro, is a general-purpose alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through the electrical grid in many parts of the world. People use ...
In a so-called balanced power system, sometimes called "technical power", an isolation transformer with a center tap is used to create a separate supply with conductors at balanced voltages with respect to ground. The purpose of a balanced power system is to minimize the noise coupled into sensitive equipment from the power supply.
A turbo generator is an electric generator connected to the shaft of a turbine (water, steam, or gas) for the generation of electric power. [ note 1 ] Large steam-powered turbo generators provide the majority of the world's electricity and are also used by steam-powered turbo-electric ships.
Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine, hydro-electric, and the grid. [ 1 ] To inject electrical power efficiently and safely into the grid, grid-tie inverters must accurately match the voltage, frequency and phase of the grid sine wave AC waveform .

The superior power-to-weight ratio of the gas turbine and its fixed speed gearbox, allows for a much lighter prime mover than for the Toyota Prius (a 1.8 litre petrol engine) or the Chevrolet Volt (a 1.4 litre petrol engine). This in turn allows a heavier weight of batteries to be carried, which allows for a longer electric-only range.
