Photovoltaic
Neoen's main solar plants are in Argentina, Australia, Canada, France, Ireland, Italy, Mexico, El Salvador, Portugal and Sweden.[38]
In France, Neoen built and operates the Cestas solar farm, in the Gironde department. With 980,000 solar panels, the 260-hectare farm was the largest of its kind in Europe when it opened on 1 December 2015. At 300 MWp it remains one of the largest in France. With an annual production of 350 GWh, it can cover household consumption for the 240,000 inhabitants of Bordeaux (excluding heating).
Neoen is operator of Providencia Solar, (101 MWp) in El Salvador, the biggest solar power plant in Central America at the time of commissioning in 2016. In 2017, the 140 MWp Capella Solar project reinforced the company's presence in El Salvador. Neoen is now also developing projects in Argentina and plans to build two 100-MWp solar farms near San Antonio de los Cobres in the province of Salta. In Mexico the company developed and operates the 800-hectare El Llano farm[39] in central Mexico (375 MWp).
In 2020, Neoen announced the construction of the Western Downs Green Power Hub (460 MWp), Australia's largest solar park. Spanning 1,545 hectares (equivalent to 2100 football pitches), the new farm has been operational since end of 2023 and will produce up to 1,080 GWh per year.[40]
In 2021, Neoen commissioned its Altiplano solar plant (208 MWp) in Argentina. Situated at an altitude of 4,000 metres above sea level, the site has some of the highest levels of solar irradiance in the world.
In 2022, Neoen launched the construction of the Fox Coulée solar power plant (93 MWp), the company's first farm in Canada,[41] and the Rio Maior solar power plant (272 MWp), the largest in Portugal.[42] Neoen has also made agrisolar energy a major focus of its development in France, with almost half of its projects integrating an agricultural component.
Neoen has continued to develop its solar activities around the world. The company announced its intentions in Sweden, where it began construction of the country's largest solar plant, Hultsfred (100 MWp)[43] in October 2023, under contract to sell 95% of its production to H&M group. In Italy, the construction of the first three solar plants started in late 2023.[44] Neoen, the renewable energy leader in Australia, has also launched construction of Culcairn solar farm,[45] which, at 440 MWp is one of the company's largest solar asset.[46]
In 2024, in Ireland, Neoen was awarded two projects for a total capacity of 170 MWp, scheduled to be operational in 2027 and 2028.[47] Neoen also started the construction of the 79 MWp Ballinknockane solar farm, which is expected to be energized mid-2026 and fully operational in the first half of 2027.[48]
Neoen remains the first independent producer of renewable energy in France beginning of 2024. In 2024 the company signed a PPA contract with SNCF,[49] the energy produced at Le Couret (139 MWp) agrisolar farm will power the equivalent of the Paris-Marseille high-speed train link.
With 164 MWp of ground-mounted PV projects awarded over the year in calls for tender issued by the French government's Energy Regulation Commission (CRE), Neoen remains the top awardee in Programmation Pluriannuelle de l’Energie PPE2, bringing its secured solar capacity in the country to over 2,500 MW.[50]
By the end of 2024, Neoen and Equinix signed the first PPA in Italy (their 5th one overall), securing 53 MW of solar energy in Italy for a duration of 10 years.
As at end of December 2024, Neoen is edging towards one hundred solar power plants in operation or under construction around the world, for a total capacity of 4.1 GWp.[51]
In 2025, Neoen inaugurated the largest solar farm in Portugal, made up of the Rio Maior Solar Farm (204 MWp) and the Torre Bela Solar Farm (68 MWp). This project brings Neoen’s total capacity in operation or under construction in Portugal to 326 MWp.[52]
Neoen also inaugurated the largest solar farm in Sweden, the Hultsfred Solar Farm, with a capacity of 100 MWp. The project is supported by a long-term power purchase agreement (PPA) signed in 2022 with the H&M Group. This agreement plays a key role in H&M Group’s goal to source 100% renewable electricity by 2030 at the latest.[53]
In September 2025, Neoen was awarded three photovoltaic projects with a combined capacity of 46.8 MWp as part of the latest government tender in France.[54]
Wind power
Neoen's wind power operations are focused on five countries where wind resources are abundant: Australia, France, Finland, Ireland, and Sweden. The 60 plants in operation or under construction have a combined capacity of 2.4 GW (as at 31 December 2024).
In 2017, Neoen commissioned the first phase of its Hornsdale Wind Farm in Australia, with 99 wind turbines and a capacity of 316 MW.
On 3 July 2020, Neoen announced the commissioning of its Hedet wind farm in Finland.[55] The 81-MW farm supplies Google with green electricity for its data centre in Hamina.
In 2021, Neoen began construction on the Kaban Green Power Hub (157 MW)[56] and Goyder South Stage wind farm (412 MW) in Australia.
On 14 May 2022, Neoen inaugurated the Madon-Moselle wind farm in France (39.6 MW). The company also opened two wind farms in the Nordics in 2022: Björkliden (40.4 MW) with partner Prokon in Finland[57] and Storbrännkullen (57.4 MW),
Energy Storage
To overcome the intermittency of renewable power sources, Neoen also develops and operates lithium-ion battery projects to store electricity.
At the end of December 2024, Neoen is a leading player in the storage sector,[63] with more than twenty batteries in operation or under construction around the world, with a total capacity of 2.3 GW / 5.3 GWh.[64]
In 2017, Neoen installed the world's first big battery (initially 100 MW / 129MWh, increased to 150 MW/ 193.5 MWh in 2020) built by the American company Tesla, at the Hornsdale Power Reserve in the Mid North region of South Australia to provide grid-support services.
In 2020, Neoen began operating a storage unit in Finland, the largest such battery facility in the Nordic countries. The 30 MW/30 MWh Yllikkälä Power Reserve One is the first large-capacity battery to be connected to the Finnish grid. Since 2022, it has been supplying rapid reserve for the implementation of EPR [AO1] Olkiluoto 3 (Europe's most powerful nuclear reactor),[65] operated by Teollisuuden Voima Oyj (TVO), the Finnish nuclear power operator.
