Never noticed a interconnector with Belgium before. Not transmiting though.  https://www.bmreports.com/bmrs/?q=eds/main  INTNEM

Good Afternoon All,

I guess there might be some pressure to get this operational PDQ given Belgium's current problems.

Regards

Yes this is the new Nemolink which is scheduled to be fully commissioned by end of January 2019, although as alluded to I expect the Belgians will be desperate to see it operating before then given their current (lack of) power crisis - I expect we will be exporting on that HVDC for a while...

But nemo link has another aspect that will affect the timing of its usefulness:
I was in kent in the summer and realised they were building a 400kv line to the coast from the major national grid routes at canterbury. looked it up and found that the nemolink makes landfall at pegwell bay at an old powerstation site but the grid connection is the lower power (132KV?) so needed replacement in order to be able to use nemolink's 1mw capacity.
its not finished yet

https://www.nationalgridet.com/infrastructure-projects/richborough-connection has a bit on this link

i wondered if they had considered building the nemolink HVDC further inland rather than doing the conversion at the coast but i coudl not find any reference to an option like that.

Mudman
The conversion equipment requires a specific land area, probably not availible at point of interconnection to existing 400kV grid infrastructure, other than space for some switchgear isolator and Vts.
However, at the former Richborough site, there is likely to be more space availible, so converters located there instead.

Philip R, That makes more sense = i'd originally assumed that they had used a former power station site due to the grid connection but the 400kv grid replacement showed that could not have been the main reason.

Hi Mudman
The former power station was connected at 132kV, suitable for the station output and location . It also served the very first DC link between England and France. (long gone).
The existing 132 does not belong to National Grid but to Uk power networks. It is effectively "embedded"

The new 400kV link to Richborough connects to the existing substation near Canterbury.

Here's a thread I did/update periodically on the planned new HVDCs into the UK.

But, that does depend on us having an agreement with the EU energy market, so what happens after March is a big unknown.

Very true. All bets are off if Brexit goes ahead. On a lot of things.
