Finance a rooftop self-consumption photovoltaic plant
The DataSun Ceuta project, led by the Avangreen group, aims to refinance a 2.8 MW rooftop self-consumption photovoltaic plant, already built and located in the port of the autonomous city of Ceuta. This installation is the largest solar plant in a European port.
The project has been declared strategic by the Assembly and Government of the Autonomous City of Ceuta. The electricity produced will be fully consumed by the city’s digital infrastructures, including a future data center, as well as by public companies in Ceuta, particularly for public vehicle fast-charging infrastructures.
Through its SPV Optimal Capital Management, the Avangreen group is launching an initial financing tranche of €2,000,000, which can be extended within a global fundraising target of €3,500,000.

The offer
A bond issuance for the refinancing of a self-consumption photovoltaic plant.
Financing Offer
The Avangreen group offers an investment opportunity in a 2.8 MW rooftop self-consumption photovoltaic plant, already built and located already built and located in the city of Ceuta.
- The electricity produced will be fully purchased by two strategic actors:
- The city’s digital ecosystem, led by a future data center and an AI incubator.
The public companies of Ceuta, to supply various uses, notably the fast-charging stations for public electric vehicles.
This first financing tranche, launched by Avangreen through a crowdfunding operation,aims to raise €2,000,000, in the form of senior debt.
Additionally, a refinancing plan is being structured to refinance both the photovoltaic plant and the future data center once it has been built and commissioned.
Investment Structure
The Avangreen Group owns 93% of the company Optimal Capital Management, which manages the assets to be financed. The remaining shareholders are local minority partners.
It is this company, Optimal Capital Management, that will issue the bonds as part of this fundraising round.
Project Guarantees
To secure the investment, several guarantees are planned:
- Pledge of 92.5% of the issuer’s share capital
- Mortgage over the concession related to the photovoltaic plant or, alternatively, a guarantee issued by the parent company
- Escrow account
- Pledge over the project’s bank accounts
- Pledge over receivables (credit rights)
This mechanism will be lifted once the guarantees of the two PPAs (City of Ceuta + Data Center) are fully effective.

The project
The Project
The DataSun Ceuta project involves a self-consumption photovoltaic plant with a solar canopy, already built and ready to produce energy.
A pioneering project for the city of Ceuta
Until now, Ceuta was the only region in Spain not meeting European decarbonisation targets. This project represents a true energy milestone for the city, becoming the first renewable energy plant integrated into its territory.
Local production serving two strategic pillars
The project supports Ceuta’s two main development priorities:
- Sustainable mobility (electric land and sea vehicles)
- Digital transformation (infrastructure and data centers)
The solar plant aims to supply electricity:
1) To charging stations for both public and private electric vehicles
2) To electric vessels operating in the Strait of Gibraltar
3) To digital infrastructure, including a data center under construction and a digital incubator supported by the Chamber of Commerce
A well-structured financing strategy
The project was fully financed through Avangreen’s equity (the sponsor) and European subsidies. This fundraising aims to refinance the initial phase, covering the equity already committed and preparing for long-term bank financing.
PPAs under negotiation
Two power purchase agreements (PPAs) are currently in progress:
-
One for supplying electricity to municipal vehicles and public services (including waste collection). The project is officially supported by the city of Ceuta, which has declared it a strategic project. This PPA is under negotiation.
-
Another for powering digital infrastructure, including the future data center (PPA already signed).
Technical and Financial Overview
- Project type: Self-consumption photovoltaic plant (rooftop)
- Installed capacity: 2.8 MW
- Estimated annual production: 5,250 MWh (20-year average)
- Completion of works: construction completed
- Total CAPEX: €4.9 million (including charging stations)
- Average OPEX: €352,000/year (over 10 years)
- Surface area: 12,000 m²
- Land type: public concession from the Port of Ceuta for 30 years
- Annual rent: approx. €50,000/year (indexed to CPI)

Our analysis
Risk overview
Counterparty risk
Risk of counterparty payment default that would jeopardize the project's cash inflows
Mitigation methods
The primary risk lies in the fixed price and the operational commencement of the power purchase agreement (PPA) with the City of Ceuta. As of today, the PPA with Procesa (City of Ceuta) is under negotiation and is expected to be signed before the end of 2025. The second PPA has been signed with the data center and will become operational once the data center is up and running (mid-2026). To mitigate this delay, the project developer has agreed to establish an escrow account to cover the initial interest payments. This mechanism will be lifted once the encumbrance of these two PPAs (City of Ceuta + Data Center) has been finalized.
Country risk
Risk of policy change
Mitigation methods
The City of Ceuta is part of Spanish jurisdiction and, therefore, falls under European jurisdiction, despite its location in North Africa. Additionally, institutional bodies support this project both at the European level (grants) and locally (the city of Ceuta's company, Procesa, which is a stakeholder in the project).
Refinancing risk
Credit risk related to the company's ability to refinance and meet its debt obligations.
Mitigation methods
The refinancing strategy has been structured through a bank refinancing over a 3-year period, which aligns with the commissioning of the data center. The primary risk associated with the refinancing is the possibility that the data center is never completed. In this case, the issue is not the repayment capacity (the project could repay a refinancing in line with market standards), but rather the total volume of debt, which could be considered too low to attract long-term banking partners.
Market risk
This risk can be caused, for example, by a change in macroeconomic circumstances, a decrease in demand in the sector in which the equity crowdfunding project operates and dependencies on other sectors.
Mitigation methods
Operating risks
Risk of poor project operation, faulty workmanship or machine breakdown resulting in poor performance.
Mitigation methods
This risk could be be caused, for example, by a change in macroeconomic circumstances, a decrease in demand in the sector in which the equity crowdfunding project operates and dependencies on other sectors.
