Terms and definitions


Frequently mentioned terms will be explained in this section.

administration agreement
administration agreement

General  Agreement between the grid owner and the designated grid administrator for the use of the grid or the transfer of its economic ownership.


allocation (allocation methodology)
allocation (allocation methodology)

General  Meter readings performed by programme responsible parties (PRPs).


alternative energy source (alternative power source)
alternative energy source (alternative power source)

General  An energy source other than gas, oil, coal or nuclear fuel.


Ampere
Ampere

General  Ampere is the unit that represents electric current, the attractive force exerted by a cable that transmits electricity on another cable that transmits electricity. Power (Watt) can be calculated by multiplying electric current (Ampere) by voltage (Volt).


annual duration of electricity failure
annual duration of electricity failure

General  The number of minutes during which an average customer with a connection does not receive any electricity, measured by the number of minutes per customer per year on the different voltage levels.


APX
APX

General  The Amsterdam Power Exchange (APX) is an electricity exchange where certified market parties trade in electricity. A major share of the trade with foreign countries takes place at the APX. Further information: the website of the APX Group.


area boundary
area boundary

General  The geographic boundary between the grids of one or more grid administrators determined by the Board of Management of the Netherlands Competition Authority.


area definition
area definition

General  Definition of the area within which the electricity grid administrator or the gas grid administrator provides the transmission of electricity or gas, respectively, based on the established geographical (municipal) boundaries as at 31 December 1998 (unless indicated otherwise).


assembly point
assembly point

General  A point in the grid, to be designated by the grid administrator, that can be used by the programme responsible parties (PRPs) to report their transmission forecasts, which equal the sum of the transmission forecasts of the grid connection points of that PRP at lower voltage levels behind the point concerned.


assumed profiled consumption
assumed profiled consumption

General  The profile fraction multiplied by the tariff correction factor, the climate correction factor and the sum of the standard annual consumption of all customers per programme-responsible party in a profile category and in a certain tariff category.


asymmetry
asymmetry

General  A situation in which the voltages and/or currents in the conductors of a three-phase system are not evenly balanced.


Auction
Auction

General  See TSO Auction.


availability
availability

General  Although the public electricity supply is a complex system, it is highly reliable (i.e. its availability is very good). As with any technology, operating disruptions cannot be entirely ruled out, but they are relatively rare. If they do occur, these situations are referred to as ‘non-availability’.


available capacity
available capacity

General  The installed capacity minus the capacity that is unavailable for the reasons listed in Article 2.4.1.3, under b, of the System Code.


average duration of the electricity disruption
average duration of the electricity disruption

General  The average time during which the transmission service to a customer is disrupted, measured in minutes per year on the different voltage levels.
