Potential Issue with Australia - Tasmania to Victoria interconnector #517

Closed superlonglong closed 7 years ago

superlonglong commented 7 years ago

Might the interconnector be showing the wrong direction?

Last night the connector was showing export from tasmania @$223 to victoria @$68, which would make the transmission company a loss of $155/MWH

As most companies don't wish to make a loss when they can avoid it, might we have the direction mixed up?

This link says we have the direction the wrong way around.

Indeed they seem to be in the wrong direction.

This is increadibly confusing. What is the correct interpretation of the TAS->VIC interconnector? image

Right now I assume a negative value from TAS->VIC means flow from VIC to TAS. Where can we access to ground truth?

superlonglong commented 7 years ago

I have looked a little further, it would appear that there was a spike to $200 in tas, so the direction is correct, even though the price looks the other way. give it another 30 mins and see how it looks.

where did you get those images from?

yeah that should be accurate.

must have had a trip in tas, price spiked, and had the official price looking strange.

you can close this again now.
