Sonnedix signed a bank loan in December 2023 to build out its European solar pipeline. Six lenders, two tranches, one stated purpose. The headline number was smaller than early reports suggested, and not all of it is money Sonnedix can spend on panels.
Key takeaways
- Sonnedix signed a $539.19 million loan facility on 13 December 2023 to finance construction of its renewable development pipeline in Europe, particularly in Spain, Italy and the United Kingdom.
- The Sonnedix facility comprises a capital expenditure tranche of about $485 million (EUR 400 million) and a letter of credit tranche of about $54 million (EUR 50 million), a total of EUR 450 million against the EUR 500 million cited in early reports.
- The lenders on Sonnedix's December 2023 facility were BBVA, CIBC, NatWest, Rabobank, Banco Sabadell and Santander Corporate & Investment Banking, advised by Eversheds Sutherland, while Watson Farley Williams advised Sonnedix.
- At the time of the loan, Sonnedix reported a 10.4 GW renewable portfolio: 3 GW operational or mechanically complete, 1 GW under construction and 6.3 GW under development.
- Enerdatics records 100 solar debt financings in Europe during 2023 totalling $12.78 billion, an average of about $128 million each, so the Sonnedix facility was roughly four times the typical European solar loan that year.
Why does the size differ from the early reports?
Because the two tranches add up to EUR 450 million, not EUR 500 million. Early coverage of the deal, including the original version of this page, carried the larger figure. Leap records the facility tranche by tranche, and that is the figure used here: about $485 million for capital expenditure and about $54 million for letters of credit, $539.19 million in all.
The gap matters less than the split. A loan headline tends to be read as cash for construction. In this case roughly one dollar in ten was never meant to be drawn as cash at all.
What is a letter of credit tranche doing in a construction loan?
It covers the guarantees a developer has to post before and during construction. A letter of credit is a bank's promise to pay a third party if the borrower fails to meet an obligation. Grid operators, landowners, offtakers and equipment suppliers routinely ask for that kind of security, and every live project in a large pipeline ties some of it up.
Without a dedicated line, a developer has to post that security from its own balance sheet or arrange it project by project. Folding a EUR 50 million letter of credit facility into the same agreement as the EUR 400 million capital expenditure facility lets Sonnedix support many projects at once from a single set of lenders. It is a sign the loan was designed for a pipeline in motion rather than for one plant.
That fits the stated use of proceeds. The facility funds construction across Europe, with Spain, Italy and the UK named as the priority markets, rather than a single named asset.
Which part of the pipeline is the loan really for?
The three named countries hold most of Sonnedix's European project count. Leap's record breaks the European footprint down as follows:
- Italy: 160 projects, 2.1 GW
- Spain: 183 projects, 1.4 GW
- Poland: 13 projects, 1.2 GW
- France: 60 projects, 845.7 MW
- United Kingdom: 10 projects, 449 MW
- Portugal: 4 projects, 224.2 MW
- Germany: 3 projects, 35.6 MW
Spain, Italy and the UK account for 353 of those 433 projects and about 3.95 GW of the roughly 6.25 GW total. Poland is the notable omission. It carries 1.2 GW across just 13 projects, which points to fewer, larger sites that may suit their own dedicated financing rather than a shared construction facility.
The loan is also small against the size of the pipeline. Sonnedix reported 6.3 GW under development and 1 GW under construction globally. A EUR 400 million capital expenditure line funds a slice of that build, not all of it, which is why the facility sits alongside the company's other borrowing rather than replacing it.
How does it fit Sonnedix's other borrowing in 2023?
It was the third large facility of the year. Leap records a sustainability-linked package of about $639 million in March 2023 and a $624 million facility for solar projects in Chile in October 2023, a loan that also funded Sonnedix's purchase of Enel's Chilean solar portfolio. With the December facility, Sonnedix's disclosed debt raised in 2023 comes to about $1.8 billion across three transactions.
The pattern continued. In February 2024 Leap records about $280 million of debt for the construction of two PV plants in Italy, one of the priority markets named in the December loan. By December 2024 the company had moved on to a refinancing of about $3.41 billion across Europe, followed in July 2025 by a refinancing of about $1.6 billion covering 1.04 GW of European projects.
Enerdatics' data shows Sonnedix's December 2023 facility was large by the standards of its market. Leap records 100 solar debt financings in Europe during 2023 with a combined value of $12.78 billion. The average is about $128 million. At $539.19 million, the Sonnedix loan was roughly four times that average and on its own equal to about 4 percent of the year's European solar debt by value.
What does the deal signal for European solar finance?
It shows lenders financing platforms rather than plants. Six banks committed to a pipeline spread across several countries, without a single named project, on the strength of a sponsor with 3 GW already operating. That is a different credit question from project finance, where the lender looks at one asset's contracts and output.
It also shows how developers sequence their debt. Corporate-style construction facilities fund the build. Once assets are operating and contracted, they can be refinanced into larger portfolio loans backed by their operating record, which is exactly the path Sonnedix's later refinancings in Leap describe. The December 2023 facility sits at the first step of that cycle.
For anyone reading European solar loan headlines, the lesson is to check the tranches. A facility quoted as one number can bundle cash, guarantees and refinancing, and only part of it buys steel and modules.
