Reserves

The Reserve Management Tool

The inputs to the SPD solver are shown in the figure and table below (adapted from Transpower's Reserve Management Tool (RMT) functional specification). There are two broad categories of input:

1. Energy and reserve offers from market participants
2. Parameters that define the Reserves requirement are calculated mostly by a software application: the RMT.

Term	Explanation
Generation Offer	Offer made to supply energy by generator
Reserve Offer	Offer made to supply reserve by a Generation Unit
FIR	Fast Instantaneous Reserve
SIR	Sustained Instantaneous Reserve
