Availability factor indicates how much of the time the plant is available to
meet demand.
The net capacity factor of a power plant is the ratio of the actual output
of a power plant over a period of time and its potential output if it had
operated at full nameplate capacity the entire time.
Solar direct normal irradiance (DNI) is the instantaneous intensity of
solar direct beam energy falling on a surface normal to the beam.
Distributed generation involves the technology of using small-scale
power generation technologies located in close proximity to the load
being served.
A ratio of yielded output per unit input for a specific process, normally
expressed as a percentage.
GHI is the instantaneous intensity of solar energy falling on a horizontal
surface. The values are usually highest in the middle of the day and
around summer, with localised variations caused mainly by variations in
atmospheric conditions, primarily cloudiness.
Specific to wind energy, it is the distance from the turbine platform to the
rotor of an installed wind turbine and indicates how high the turbine
stands above the ground, not including the length of the turbine blades
The discount rate often used in capital budgeting that makes the net
present value of all cash flows from a particular project equal to zero
The land use factor is the ratio between the directly utilised ground area
of a technology deployment and the total land area required for
deployment, including necessary redundant land area, such as that
required between solar thermal mirrors to avoid shading issues.
A present value measure of the lifecycle cost of generating power from a
given plant considering the capital cost, operating costs (including fuel),
capacity factor, financing cost, and incentives. The Levelised Cost is a
useful calculation because it allows comparison of different generation
technologies on an equal basis.
