Generators

The generators are entered individually into EMarket. There are three different types of generators;

• Generic (these are thermal, geothermal and wind)
• Hydro Station (simple one storage, one inflow type)
• Hydro System (complex multi station/reservoir hydro generators)

Many of the generator types have elements in common such as Name, Version, Node.

The Generator Window has the following components:

1. A 'Common Generation Data Area' which is identical for all generator types
2. An area containing type specific data

Common Generator Data Area

Name	Used to reference the generator in Schedules, Formulae and Output Data
Version	The Version name for this Generator Resource Instance
Description	Free text field for information about the Generator
Gen Class	Generator type (Generic, Hydro Station or Hydro System) When changing this input a prompt window is displayed, as this may result in some of the information previously entered for the resource being lost.
Node	The Node where the Generator injects power into the Grid.
Comm Date	Commissioning Date - the first date upon which the Generator could submit Offers. This field allows you to model a Generator as coming on stream at a particular time in the future.
Moth Date	"Mothball" date - the last date upon which the generator can submit Offers. this date should be set well into the future for generators which are likely to run indefinitely.
Gen Type	Type of Generator, e.g. Steam Turbine
Fuel Type	Fuel used by Generator, e.g. Coal
Efficiency %	Describes the efficiency of the Generator. (Not used by EMarket but can be accessed to calculate fuel burn based on Generation Output.
Non Fuel M.C. ($/MWh)	This figure is used to calculate operating costs for Hydro Generators.
Max Output (MW)	The maximum output of the station.
Unit Size (MW)	The capacity of component units in MW. This is used when calculating Reserve risk and Reserve dispatch. You should enter a unit size of zero if the Generator will not be modelled as a Reserve risk. The Unit Size (MW) setting and the output of a Generator at any given Tick determines the risk set by the Generator.
