Price api endpoint seems to be having issues at the moment

[Mijawel]

I'm assuming you know already but just in case, the prices endpoint seems to be returning tariffs that don't make sense:

Here is a summary followed by the raw output: {perKwh: 30.12297, spotPerKwh: 19.49739, nemTime: 2024-09-26T16:55:00+10:00} {perKwh: 204.0065, spotPerKwh: 29.60355, nemTime: 2024-09-26T17:00:00+10:00} {perKwh: 236.56839, spotPerKwh: 30.45084, nemTime: 2024-09-26T17:05:00+10:00} {perKwh: 223.65405, spotPerKwh: 38.03492, nemTime: 2024-09-26T17:10:00+10:00} {perKwh: 254.67663, spotPerKwh: 52.74907, nemTime: 2024-09-26T17:15:00+10:00} {perKwh: 259.79592, spotPerKwh: 1268.74393, nemTime: 2024-09-26T17:20:00+10:00} {perKwh: 295.61723, spotPerKwh: 1589.7618, nemTime: 2024-09-26T17:25:00+10:00} {perKwh: 2021.72801, spotPerKwh: 1925.0, nemTime: 2024-09-26T17:30:00+10:00} {perKwh: -18.52582, spotPerKwh: 19.49739, nemTime: 2024-09-26T16:55:00+10:00} {perKwh: -176.60176, spotPerKwh: 29.60355, nemTime: 2024-09-26T17:00:00+10:00} {perKwh: -206.20347, spotPerKwh: 30.45084, nemTime: 2024-09-26T17:05:00+10:00} {perKwh: -194.46316, spotPerKwh: 38.03492, nemTime: 2024-09-26T17:10:00+10:00} {perKwh: -222.66551, spotPerKwh: 52.74907, nemTime: 2024-09-26T17:15:00+10:00} {perKwh: -227.31941, spotPerKwh: 1268.74393, nemTime: 2024-09-26T17:20:00+10:00} {perKwh: -259.88424, spotPerKwh: 1589.7618, nemTime: 2024-09-26T17:25:00+10:00} {perKwh: -1829.07585, spotPerKwh: 1925.0, nemTime: 2024-09-26T17:30:00+10:00}

What doesn't make sense?

[Mijawel]

Why would the perKwh value be -1829 during the same interval as the spotPerKwh be 1925?

Oh wait. Sorry, the channel type is feed-in.

On that note, I always thought the spot price was the feedIn price. What does it mean to have a separate perKwh and spotPerkwh price on the feed in channel that appear to be different from the spot price on the general channel?

[madpilot]

No, feed in price is spot price x loss factors. When the price is high the loss factors make a bigger difference.

[Mijawel]

Ok that makes sense. And same as with general prices, the predicted price on the feedin channel should be a bit more accurate than the perKwh price?

[madpilot]

Yep. The predicted price is predicting the spot price and then we just apply network fees over the top
