€507 Million Solar-and-Storage Deal to Power Italy’s Green Transition

A major clean energy investment is set to accelerate Italy's transition away from fossil fuels, with the European Investment Bank (EIB), Natixis Corporate & Investment Banking, and Sunprime Holdings signing a €507 million project finance agreement for a large-scale solar and battery programme.

Dubbed Project Sophocles, the initiative combines distributed solar generation with advanced battery storage—positioning it as one of Italy's most significant hybrid renewable energy projects to date.

200 Solar Plants and Large-Scale Battery Storage

The programme will fund:

• Around 200 solar photovoltaic (PV) plants

• Total capacity of 290 MWp (solar)

• 350 MW of battery energy storage (BESS)

By integrating solar with storage, the project aims to:

• Improve grid flexibility

• Stabilise renewable energy supply

• Reduce reliance on fossil fuel-based power

The EIB is providing up to €271 million of the total financing.

Clean Power for 160,000 Homes

Once operational, Project Sophocles is expected to:

• Generate 416 GWh of renewable electricity annually

• Supply power equivalent to over 160,000 households

• Avoid 2.86 million tonnes of CO₂ emissions over its lifetime

These outcomes directly support Italy's climate targets and the EU's broader decarbonisation strategy.

Strengthening Energy Security and Grid Stability

The battery storage component is a critical feature of the project, enabling:

• Frequency regulation

• Peak demand management

• Congestion relief in the grid

This reduces dependence on gas-fired plants and enhances the resilience of Italy's electricity system—especially as renewable penetration increases.

Backed by EU's InvestEU and REPowerEU Strategies

The project benefits from the InvestEU Guarantee, part of a broader EU effort to mobilise €372 billion in sustainable investment by 2027.

EIB Vice-President Gelsomina Vigliotti said:

"Project Sophocles shows how solar and storage can work together to create a cleaner, more flexible and secure energy system while crowding in private capital."

The initiative also aligns with:

• Italy's National Energy and Climate Plan (2030)

• The EU's REPowerEU strategy, aimed at reducing fossil fuel dependence

Distributed Energy Model with Minimal Land Impact

Most installations will be deployed on:

• Industrial rooftops

• Commercial and agricultural facilities

• Previously unused or degraded land

This approach ensures:

• Efficient land use

• Reduced environmental footprint

• Proximity to energy demand centres

Sunprime CEO Antonio Mazzitelli highlighted the strategy:

"Solar projects can deliver competitive, sustainable energy where it is most needed—close to industrial consumption and existing infrastructure."

Economic Boost: Jobs and Local Industry Growth

Beyond environmental benefits, the project is expected to generate significant economic impact:

• 1,400 person-years of construction employment

• Around 120 permanent jobs during operations

The distributed model will also support:

• Local supply chains

• Regional economic development

• Energy cost resilience for businesses

Innovative Financing and Revenue Model

The project will be structured into 6–12 asset clusters, supported by grid infrastructure and diversified revenue streams, including:

• Italy's FER-X Contracts for Difference for solar

• Capacity market participation for battery systems

• Tolling agreements and wholesale electricity markets

This blended model enhances financial stability and investor confidence.

Expanding a Proven Partnership

Project Sophocles builds on a successful earlier collaboration between Sunprime, EIB, and Natixis, reinforcing confidence in:

• Sunprime's execution capability

• The scalability of distributed renewable platforms

The company aims to reach:

• 750 MWp of solar capacity

• 1,400 MWh of battery storageby 2027.

A Landmark Step in Europe's Energy Transition

As Europe accelerates its shift to clean energy, Project Sophocles highlights a key trend: the integration of renewables with storage to deliver reliable, scalable, and sustainable power systems.

With strong public-private backing and a focus on decentralised energy, the project represents a blueprint for future green infrastructure investments across Europe.
