Q&A: If you break it down, it is tried, tested: Xlinks
London, 18 November (Argus) — Project developer Xlinks plans to connect 11.5GW
of Moroccan wind and solar capacity, and a 5GW battery energy storage system,
with the UK through two 1.8GW sub-sea cables, an ambitious project using "tried
and tested" technologies. Argus spoke to chief executive James Humfrey about the
project's timeline and progress. Edited highlights follow: For those who may not
know, can you describe the Xlinks project? We are excited to bring clean energy
from the Moroccan Sahara to north Devon. This will be a transformational surge
of reliable, clean power, and we will bring it during the hours the UK needs
electricity most, supporting Britain's ambitions to decarbonise, which you see
in the news and most recently in Baku [at Cop 29]. The project will benefit the
broader economy by displacing expensive, volatile imported gas and reducing
wholesale power prices. It will also help balance the grid, feeding into the
south of England, which has very high demand without significant grid upgrades.
The independent Afry consultancy group calculated the project's socioeconomic
benefit to be £17bn. It will also offer a reliable wind and solar energy supply,
with nearly two times the solar radiation factor. [Moroccan] wind generation is
slightly negatively correlated to UK output, helping overcome the dunkelflaute
[dark lull] scenario, which is the advantage of moving electrons in time and
space. This reliability complements the UK domestic renewables pipeline,
primarily offshore and onshore wind, while aligning with Morocco's green export
ambitions. Can you provide our subscribers with an update on the project, its
timeline and any key milestones? It will be ready next decade. And we are set up
to rapidly mobilise and deliver the project. We have a strong team of people who
have worked on these projects before. For example, our HVDC cable team, led by
Nigel Williams, built the North Sea Link between Blythe and Norway, tackling
more complex problems than we face. They've built lots of interconnectors and
know how to do it. I realise that Xlinks holds connection agreements for two
1.8GW connections with National Grid. Has Xlinks progressed with other national
authorities, particularly those through which the cable will transit? We have
worked with the Moroccan government, including [plans] around the land and
conducting one of the world's longest [wind and solar] measurement campaigns.
So, we've got excellent resource data regarding wind and solar energy. We have
already obtained permits from [the transit countries] for route surveys and we
have vessels in the water at the moment, undertaking geophys and geotech. Next
year, we'll apply for the final installation permits, based on the environmental
studies and other benefit data. We've taken a longer but less challenging route,
with lower water depths, making it technically easier. It is, for example, less
deep than the North Sea Link, which was a deliberate technical decision. The
previous government marked Xlinks as a project of national significance . Do you
expect any change under the new administration, and in what way has this
classification affected progress ? No, it hasn't affected us. We completed the
public consultations over the summer and are about to submit our DCO
[development consent order] application, which is a large amount of work. We
have finished that, with no changes [since the change of government]. It is
probably worth saying that our land route in Devon is all underground. We don't
have any pylons, which is much less intrusive. Has this improved Xlink's ability
to generate capital interest? Is there any specific attempt to generate interest
from sovereign wealth funds or other institutional investors? We've been
fortunate that our blue-chip investors [Octopus, TotalEnergies, Taqa, GE Vernova
and Africa Finance] are very keen on the project, and it matches their strategic
plans. They want to go all the way through to construction. We may have further
investors at the close, but they are our primary focus right now. Do you have an
update on the contract for difference (CfD) process? Xlinks has published a
desire to reach a £70-80/MWh strike price at 2012 prices. Yes, that remains our
guidance. We are working through the CfD and Treasury Green Book process with
the Department of Energy. It is quite a structured process. How do you reconcile
that strike price with far lower prices reached in recent allocation rounds
(AR), namely AR6, although the technologies are not directly comparable?
Firstly, in the NESO report, the forecasts for offshore wind [prices] rise quite
a bit as they move out to 2030, so AR6 is a reference, but there are figures in
the NESO report that are above our £70-80 [strike price]. Importantly, it is not
a comparison between apples and apples. Our profile is completely different from
that of offshore wind. We offer firm power for 19 hours a day, optimised for
peak hour demand and very high reliability, akin to nuclear. Given our
flexibility, we can also provide various other services, including frequency and
even black start services. The development contains ambitious plans for
vast-scale battery storage of up to 5GW. Given the difficulties faced by several
European battery manufacturers, do you foresee any significant supply chain
challenges? We have an ongoing battery procurement process, and the invitations
to tender have gone out. We've had good interest at competitive levels and are
confident in it. We are not seeing any challenges, and it's going very well. And
what does the flexibility and opportunity a battery offers at this scale mean
for a project like Xlinks? It allows us to optimise during the dinural shift of
solar power, when the UK grid needs us most. Additionally, it gives us a
sub-second response, giving us flexibility and opening the door to the frequency
services we mentioned earlier. It is very valuable and allows us to provide
benefit at scale and at speed. Does the UK's ambition, corroborated by NESO's
latest report to become a net power exporter beyond 2030, change the project's
economic viability or impact it in any way? No, the report does not change our
viability or where we fit in the future system. In fact, it further emphasises
the part we can play. If you look at demand, it is very likely to increase again
by another 23pc in 2030-35, and considering our generation profile, producing in
periods of low domestic wind production, [it fits well]. Additionally, when we
compare it to other sources of clean [baseload] generation, such as nuclear, you
see solar, wind and transmission projects have extremely good predictability of
outcome and a shorter delivery timeline. Xlinks has stated an ambition to
investigate a Morocco-German link. What might this look like? Would it involve
an entirely new generation facility, too? First, the Morocco-UK power project is
very much our first priority. We're focused on that and we think bringing this
to a financial close will help unlock a range of projects across the industry.
And demonstrate the art of the possible. We do have some early feasibility work
going on. It would be entirely separate, and that would include generation as
well. Do you have any closing thoughts that you would like to leave our
subscribers? What is different about this is its scale. But when you break it
down, these are all tried-and-tested technologies. There is nothing unusual
about them, whether wind and solar in Morocco or large-scale batteries. We are
not an interconnector, but long-distance transmission has a long history in the
UK. When you look at the water depths, it is less complicated than North Sea
Link. It has all been done before, in its parts — just the scale is different.
