NO4 remove Melkøya power plant (auto-consumption) #1430

Open brunolajoie opened 6 years ago

brunolajoie commented 6 years ago

In NO4, our ENTSOE parser for real time generation per category seems to includes a gas fired power plant (Melkøya) that is not allowed to deliver to the grid. It is used for self-consumption in an LNG factory up there.

We should try to find real-time power production from this plant in the Transparency platform, and net it from our current NO4 parser.

Maybe this is something that needs to be told to entsoe so they update it on their end?

@brunolajoie any news?

I'll discuss it with my source

Last I heard the plant at Melkøya is required to deliver power through a 132kV cable in emergency situations. Statnett is currently extending the 400kV grid from Balsfjord to Alta(2021) and Skaidi(2023). After that the chance of it delivering to the grid is pretty much 0. A 400kV from Skaidi to Melkøya is also possible as Equinor indicates the need for an additional 270MW.

Research indicated 229MW capacity from five turbines.

The only gas power production for NO4 is from this plant afaik.

I am unsure if there are any direct actions here. Do we know for certain whether we should subtract it? I am not certain whether our current architecture supports this.

The plant has been out of commission for months after a fire broke out during restart from maintenance. My understanding is that it will not deliver power to the main grid under normal operation as it is there to power the refinery on the island. Melkøya only has a single 132kV connection currently and that is nowhere near enough to run the entire operation.

It is kind of the same with the Mongstad plant that is hopefully shutting down its last turbine this year after several extensions.

Both of these can deliver to the grid if needed.

The offshore platforms have lots of gas turbines that have no production data available. The numbers for Norway would look a lot worse if we could include emissions from these.

My statement of it being the only gas production might not be accurate anymore as there have popped up more gas as source from ENTSOE. It might be district heating plants or other sources I am not aware of. Though these are usually burning waste and wood chips from logging industry. They do have backups and extra for peak loads. Mostly biodiesel and electric, but there are a few that can run on LNG as well. I believe Haraldrud heating plant in Oslo have a 100MW backup that can use LNG or bio-oil.

The only gas plant I know of is a small 10MW one near Kollsnes that burns waste gas from Kollsnes gas processing plant that would be torched.
