New price signal in renewables, ERG Priolo Gargallo wind farm shows its role

Italian renewable player ERG leans heavily on its onshore wind fleet. One example is the Priolo Gargallo wind farm in Sicily, which feeds green power into the Italian grid under regulated and market conditions and illustrates how the group earns money with wind assets.

ERG’s onshore wind business remains the backbone of the Italian group’s renewable strategy, and the Priolo Gargallo wind farm in Sicily is one of the assets that shows how the company turns installed capacity into recurring cash flow in its home market. The site sits in the municipality of Priolo Gargallo in the province of Syracuse, contributing to ERG’s roughly 1.5 GW portfolio of onshore wind capacity in Italy and helping the company rank among the country’s larger independent renewable producers.

Priolo Gargallo wind farm: what the asset delivers

Priolo Gargallo is part of ERG’s broader onshore wind platform, which totals about 2.1 GW of installed capacity across several European countries, with Italy as the single largest market. The group says its Italian onshore wind plants produced around 2.4 TWh of electricity in 2023, highlighting how individual farms such as Priolo Gargallo contribute to a sizeable stream of regulated and merchant revenues in the Italian power market. ERG outlines its wind portfolio and production metrics in detail in its latest annual report, which also confirms the geographic distribution of assets between Italy, France, Germany, the United Kingdom, Poland, Bulgaria and Romania. The company’s onshore wind business overview shows that wind remains the largest technology in ERG’s fleet by installed capacity.

While ERG does not usually break down operating and financial data for individual plants like Priolo Gargallo, the site follows the standard business model the company applies to its wind portfolio in Italy: long-term concessions and grid connections, a mix of incentive schemes and market-based power sales, and operational optimization to keep turbine availability high. In its 2023 annual report, ERG reports an average load factor of roughly 27 percent for Italian onshore wind and notes that the EBITDA margin of its wind operations remains above 70 percent, illustrating the profitability of mature, well-managed assets plugged into a supportive regulatory regime. Industry databases and regional planning documents identify Priolo Gargallo as one of several wind farms in Sicily that benefit from strong wind resources and relatively high full-load hours compared with much of continental Europe, which in turn supports the economics of ERG’s investment in the region.

Strategically, ERG classifies its onshore wind assets as “core” infrastructure, with Italy singled out as a key market for further repowering and selective expansion. Repowering older plants - replacing first-generation turbines with more powerful and efficient machines on existing sites - is a central element of the company’s industrial plan, enabling higher output per site without expanding the land footprint. In Sicily, where Priolo Gargallo operates alongside other ERG-owned farms, the group aims to leverage established grid connections and local know-how to increase the productivity of its portfolio over time. The latest industrial plan for 2024 to 2026 presents onshore wind as a stable cash generator that co-finances growth in solar and battery projects, while maintaining a disciplined capital structure and a dividend policy tied to recurring cash flow.

From an environmental perspective, ERG estimates that each terawatt-hour of wind generation in its portfolio avoids roughly 400,000 tons of CO2-equivalent emissions compared with the current Italian power mix, underlining the contribution assets like Priolo Gargallo make to national and European decarbonization targets. In its sustainability reporting, the group stresses that the bulk of its installed capacity is now from zero-emission sources, a shift that was accelerated by the sale of its legacy oil refining and fuel marketing activities over the past decade. Priolo Gargallo’s generation feeds directly into the Italian high-voltage network, supporting grid decarbonization in a region historically dominated by thermal power. ERG’s latest sustainability report includes specific emissions factors and avoided-emission calculations for wind, which are applied across the portfolio of which Priolo Gargallo is a part. The sustainability report details ERG’s environmental metrics and decarbonization trajectory, including the role of onshore wind generation.

As part of its asset management approach, ERG highlights predictive maintenance, digital monitoring and centralized operations control as key tools to keep plants like Priolo Gargallo online and responsive to market signals. The company operates a control room that supervises its fleet across countries, allowing technicians to spot anomalies early and schedule maintenance downtime efficiently, which helps sustain high availability rates. In Italy, ERG’s onshore wind assets participate in the wholesale power market and, when applicable, in capacity mechanisms and ancillary services, creating several revenue streams from the same installed capacity base. Management also emphasizes community engagement and landscape considerations in Sicily and other southern Italian regions, as local acceptance is important for both maintaining existing assets and obtaining permits for repowering projects. The company’s non-financial disclosures describe stakeholder consultations and environmental impact mitigation measures implemented around its wind farms.

In ERG’s current portfolio mix, onshore wind still accounts for the largest share of installed capacity and EBITDA contribution, even as solar and storage grow from a smaller base. That makes assets such as Priolo Gargallo strategically important: they provide relatively predictable cash flow that supports dividends and new investments under the group’s industrial plan. ERG is listed on the Italian stock exchange Euronext Milan, and its shares (ISIN IT0001157020) closed at EUR 28.50 on 06/14/2026 according to recent market data. Borsa Italiana’s listing information confirms the trading venue and identifies ERG as a renewable energy operator focused on wind, solar and hydro assets.
