Final reserve prices

Final reserve price files are delimited but do not contain a header row. The columns, as defined in the WITS user guide, are:

• GIP_GXP – Grid Point applicable
• TRADING_DATE – Applicable trading date (dd/mm/yyyy)
• TRADING_PERIOD – Trading Periods from 1 to 50
• PRICE_6S – The 6 second reserve price per MW in NZ$
• PRICE_60S – The 60 second reserve price per MW in NZ$
• RUN_TIME – Solution run time (DD/MM/YYYY HH:MI:SS)
• PRICE_TYPE – F for Final.

Final reserve prices are usually published as a single file containing all trading periods (midnight to midnight) for that day. However, if more than one days' worth of final prices are published in a day, then the zip file for that day will contain more than one CSV file.
