I am just starting out experimenting with the EMI Real Time Prices API and I have two questions:
1) Where can I find a definition of each of the columns returned by a call to the Real Time Prices API ? I get the following columns returned but it would be useful to know whether my assumptions about them are correct:
interval - What time zone is this in, is it UTC See 2) below ?
interval_datetime - What time zone is this in , is it UTC See 2) below ?
five_min_period - What does this mean, is it the 5-minute segment of the hour (ie there are values 1 to 12 ) ?
isDayLightSavingHR - What does the HR indicate ? As at 25May2019 (ie Daylight Savings is NOT in force) every row shows a value of <zero>. I would expect to see value of 1 when New Zealand is in Daylight Savings, but I notice that data returned for mid-Jan 2019 still shows a value of <zero>
pnode - This looks to be the power node. Is this correct ?
load - What scale is this / Megawatts, Gigawatts ?
generation - ??????
price - I assume that this is NZD, but again, $ per what ? (No pun intended)
2) What is the timezone being used for interval and interval_datetime?
When I ran the following query against the Real Time Prices API at 2019-05-25 15:30:
https://emi.azure-api.net/rtp/?$filter=interval_datetime gt datetime'2019-05-24T00:45' and interval_datetime lt datetime'2019-05-25T15:15'
the latest value I see returned for interval_datetime is '2019-05-25T01:25:00'. Is this simply a delay in making prices available or is the value offset by 14 hours for some reason ?
Any help or guideance would be appreciated.
