CPP Investments Partners With Elia Group to Develop Tarchon Interconector
Veselina Petrova of Renewables Now reports Elia, CPP Investments buy 1.8-GW North Sea grid link project from CIP:Belgian transmission system operator Elia Group SA (EBR:ELI) and Canada Pension Plan Investment Board (CPP Investments) said today they have acquired the 1.8-GW Tarchon, a subsea interconnector project planned to link Germany and the UK to allow the countries to share surplus clean electricity.
The project will be bought from Copenhagen Infrastructure V, a fund managed by Denmark’s Copenhagen Infrastructure Partners (CIP). Specifically, CPP Investments will buy a majority stake in the project, spending CAD 1 billion (USD 709.7m/EUR 622.5m) on a 75% ownership, while Elia will own the remaining 25%. The Belgian company will acquire minority holding through its WindGrid subsidiary, which invests in electricity transmission and offshore wind grid infrastructure.
The new asset will extend CPP Investments’ commitment to invest in developing European energy infrastructure and support Elia’s core regulated transmission activities. The deal is pending regulatory clearance and is expected to close by end-2026.
Tarchon will be a high-voltage direct current (HVDC) link consisting of an underground and subsea cable network with a length of around 760 kilometres (472 miles), stretching between Germany and East Anglia in the North Sea. The facility will connect the two countries’ energy markets and help enhance the security and reliability of their electrical systems. The power to be transmitted through the grid link will help supply up to 1.9 million households.
The interconnector project is still in an early development phase and its exact route in the UK, Germany and Dutch territorial waters is yet to be determined.
Nadja Skopljak of offshore Energy also reports the 760-kilometer UK-Germany interconnector gets new owners, construction start expected in 2030:
Canada Pension Plan Investment Board (CPP Investments) and Elia Group, through its international development platform WindGrid, have acquired a subsea interconnector project that will link the UK and Germany from Copenhagen Infrastructure V, managed by Copenhagen Infrastructure Partners (CIP).
Approved by Great Britain’s energy market regulator Ofgem in 2024, the Tarchon interconnector will be approximately 760 kilometers long, connecting East Anglia and Niederlangen, Germany, and will deliver up to 1.4 GW of electricity capacity.
As a regulated asset, the project is progressing through the relevant regulatory approvals process in the UK and Germany.
“We are delighted to be partnering with Elia Group on the development of the Tarchon interconnector. This acquisition is rooted in a shared commitment to long-term value creation and responsible infrastructure development,” said James Bryce, Head of Infrastructure at CPP Investments.
“By combining CPP Investments’ global investment capabilities with Elia Group’s proven expertise in designing, building and operating complex transmission systems, the partnership is well positioned to deliver a project such as Tarchon, while also allowing us to generate strong risk-adjusted returns for CPP contributors and beneficiaries.”
CPP Investments will provide a C$1 billion commitment for a majority stake in the project, while Elia Group’s investment through WindGrid is structured as a minority participation, representing a 25% look-through stake, and remains limited in scale relative to the group’s overall investment program, consistent with its disciplined financial policy.
The transaction is expected to be completed by the end of 2026, subject to regulatory and closing conditions.
The earliest start date for the construction of the link in the UK is 2030, with commercial operations targeted for 2034.
“Tarchon is an important project for WindGrid and reflects our partnership-led approach to supporting selected transmission infrastructure opportunities that are complementary to Elia Group’s core regulated activities. As electrification progresses and power systems become increasingly interconnected, well-developed cross-border infrastructure will remain important for the energy transition,” said Daniela Baratto, CEO of WindGrid.
Earlier today, CPP Investments issued a press release stating it is expanding its partnership with Elia Group by acquiring the Tarchon interconnector project from Denmark’s Copenhagen Infrastructure Partners:
TORONTO, Canada / BRUSSELS, Belgium (July 29, 2026, 1:00 a.m. EDT / 7:00 a.m. CEST) – Canada Pension Plan Investment Board (“CPP Investments”) and Elia Group, through its international development platform WindGrid today announce the acquisition of Tarchon, a subsea interconnector project between Germany and the UK, from Copenhagen Infrastructure V (managed by Copenhagen Infrastructure Partners). The investment is being made by CPP Investments alongside WindGrid to extend CPP Investments’ ongoing commitment to invest in developing European energy infrastructure while complementing Elia Group’s core regulated transmission activities.
The partnership reflects the continued evolution of a trusted and well-established collaboration between CPP Investments and Elia Group, built on a strong alignment of interests, complementary capabilities, and a shared long-term perspective.
At a time when the energy transition requires significant investment in grid infrastructure, projects such as the Tarchon interconnector will contribute to a more resilient and interconnected European power system. Tarchon will provide a 1.4 GW high-voltage direct current (HVDC) link between the United Kingdom and Germany, that will strengthen cross-border electricity flows, enhance security of supply, and enable the efficient integration of renewable energy across markets, supporting the long-term decarbonisation of both systems. As a regulated asset, the project is progressing through the relevant regulatory approvals process in the UK and Germany.
CPP Investments will provide a C$1 billion commitment for a majority stake in the project. Elia Group’s investment through WindGrid is structured as a minority participation, representing a 25% look through stake, and remains limited in scale relative to Elia Group’s overall investment programme, consistent with its disciplined financial policy.

Energy is a very important theme for CPP Investments and I'm talking about energy at large (not just renewables).
Why is this deal important? From a simple Google search:
Cross-border interconnectors are essential for Germany's energy transition, enabling renewable integration with neighboring countries and balancing demand to lower system costs. Policy frameworks aim for significant increases in interconnection capacity to optimize the European market, alongside the expansion of internal HVDC corridors. Read more from Agora Energiewende regarding the integration of the Nordic and German electricity systems here.
Clearly, interconnectors are essential for Germany's growing electricity needs and energy transition, as well as the UK's and other neighbouring countries.
The Tarchon subsea interconnector project and other similar projects will play an integral role in this energy transition.
This is a smart way to invest in the future energy needs of Europe, one that will deliver consistent, inflation-adjusted cash flows once this project is operational in 2034.
That is why CPP Investments is providing a substantial C$1 billion commitment for a majority stake in the project (75%).
Partnering up with Elia Group will allow them to have a partner with in-depth operational expertise via its Windgrid subsidiary.
On LinkedIn, CPP Investments posted this:
We’re committing C$1 billion alongside Elia Group and WindGrid to invest in Tarchon, a 1.4 GW subsea high-voltage interconnector project between Germany and the UK. The partnership reflects the continued evolution of a trusted and well-established collaboration between CPP Investments and Elia Group, built on a strong alignment of interests, complementary capabilities, and a shared long-term perspective. Tarchon will provide a 1.4 GW high-voltage direct current link between the United Kingdom and Germany, that will strengthen cross-border electricity flows, enhance security of supply, and enable the efficient integration of renewable energy across markets, supporting the long-term decarbonisation of both systems.
Again, this project will take time to develop and is a long-term investment, but by getting in there early with a strategic partner, CPP Investments will reap great long-term returns.
This may be the first greenfield infrastructure project CPP Investments has invested in (not pure greenfield, as CIP got the project off the ground, but they definitely don't do these types of projects often, that's for sure).
And that also speaks volumes about this deal.
Below, at the heart of Europe, Germany has the advantage of being able to source electricity from its many neighbors. That's why construction is underway on the next generation of interconnectors, which is creating lots of business opportunities.
Watch this clip, it's obvious that interconnectors are quickly becoming the cornerstone of the EU's energy policy and by 2050, many of these projects will be operational, providing energy and allowing countries to realize on their net zero targets.
