# Caruna and Tarchon: funding before and after an infrastructure closing

Caruna’s deferred buyer payment and Tarchon’s continuing developer funding show why infrastructure transaction cash has a closing calendar.

The Caruna and Tarchon transactions put infrastructure capital on opposite sides of closing. Caruna’s buyer disclosed a large deferred payment; Tarchon’s project announcement kept development funding with CIP until completion. The pension investors involved are Ontario Teachers’ Pension Plan and CPP Investments.

## Caruna: payment extends beyond closing

On July 21, 2026, [Ontario Teachers announced an agreement to sell its 40% shareholding in Caruna](https://www.otpp.com/en-ca/about-us/news-and-insights/2026/ontario-teachers-reaches-agreement-to-sell-stake-in-caruna-to-iberdrola/). The transaction valued the business at approximately €5 billion including financial debt. That enterprise value describes the business being transferred, rather than the pension’s cash receipt.

[Iberdrola’s July filing](https://www.cnmv.es/webservices/verdocumento/ver?t=%7B2336bc80-7814-4e84-9357-92acf07c7aa4%7D) identifies Iberdrola Energía Internacional as buyer and Suomi Power Networks TopCo, controlled by Ontario Teachers and KKR-managed funds, as seller. The consideration for 80% of Suomi Power Networks MidCo, which indirectly holds the Caruna companies, was approximately €2.014 billion: €1.014 billion at closing and €1 billion payable within the following 30 months, subject to customary adjustments.

The later [nine-month 2026 results presentation](https://www.cnmv.es/webservices/verdocumento/ver?t=%7B8b0f228b-82f4-441d-b0f9-a92fc6535454%7D) describes a €2 billion equity investment, with €1 billion deferred for one year. A year fits within the earlier 30-month window; the descriptions alone do not establish a contract amendment. The presentation still describes an agreement and progress toward approvals, rather than a completed payment.

Together, the disclosures describe about half of aggregate buyer consideration being deferred beyond closing. They do not allocate that deferred amount to Ontario Teachers. An investor monitoring this realization should distinguish the value of the agreed sale from the timing and amount of the pension’s eventual receipts.

## Tarchon: CIP keeps funding development until completion

The [July 29 joint announcement from Elia Group and CPP Investments](https://investor.eliagroup.eu/-/media/project/elia/shared/documents/press-releases/2026/20260729_pressrelease_elia-cpp-investments-tarchon_en.pdf) describes a C$1 billion CPP commitment for a majority position in Tarchon, the planned UK–Germany interconnector. WindGrid, Elia’s development platform, would hold a 25% look-through stake. The named seller is Copenhagen Infrastructure V, managed by Copenhagen Infrastructure Partners. Completion was expected by year-end 2026, conditional on regulatory clearance and other closing requirements.

The [project’s July 30 statement](https://tarchoninterconnector.com/elia-group-and-cpp-investments-announce-acquisition-of-the-tarchon-interconnector-project/) supplies the consequential funding detail: CIP would continue managing, developing and financing the project until completion. The announcement of incoming ownership therefore did not itself mark the end of CIP’s stated development-funding role. The project could continue moving toward handover with that responsibility still assigned to CIP.

CPP’s C$1 billion is a commitment attached to the incoming majority position. It is not a disclosed closing cheque or a published draw calendar. Nor does WindGrid’s percentage establish CPP’s exact share. The documents identify the transition in ownership and the continuing pre-completion role without separating acquisition consideration from subsequent development capital.

## Implications for allocator research

For a fundraising team, the Caruna follow-up concerns the pension’s receipt schedule and allocated proceeds. Tarchon calls for a discussion of how the incoming investor’s committed capital will support the project after handover. Those are different capital-planning discussions even though both transactions appear in pension infrastructure activity.

Read alongside Altss’s [atNorth analysis](https://altss.com/blog/atnorth-cpp-equinix-acquisition-equity-expansion-financing), these cases add a practical field to an allocator brief: the funding phase around closing. Record it alongside the ownership position and capital instrument, with the named party responsible for each obligation.
