History
Founded in 2008, Neoen opened its first power plant in France in 2009 and reached its breakeven point in 2011. In 2014, the company began its international development with the opening of three solar plants in Portugal: Seixal, Coruche and Cabrela. Cestas, the most powerful solar plant in Europe with 300 MWp, was opened in south-west France in 2015. In 2016 Neoen commissioned the largest solar park in Central America. The company's total capacity in operation or under construction exceeded 1 GW. The following year, Neoen commissioned the worlds’ first big battery, Hornsdale Power Reserve, in Hornsdale, Australia and announced its intention to triple its business by 2020.The company went public on 16 October 2018, entering Euronext compartment A, with the support of its historical shareholders. It became the youngest French company in its field to surpass a capitalization of one billion euros. The same year, its total capacity in operation or under construction reached 2 GW.
In 2019, Neoen sold its only biomass unit and continued its international expansion, with an agreement to provide wind power for Google in Finland and the financing of a 375-MWp solar park in Mexico providing energy at US$18.93 per MWh. That year, the company reached the milestone of 1 GW of assets in Australia alone.
In 2020, building work began on the Yllikkälä Power Reserve in Finland Work also began on Western Downs, Neoen's largest solar park and the largest of its kind in Australia.
In June 2020, the company entered the SBF120, MSCI France Small Cap Index and S&P Global Clean Energy indexes.
In April 2021 Neoen increased its capital by €600 million. The company had 4.1 GW in operation or under construction in 15 countries and set itself the target of reaching 10 GW in 2025.
In July 2021 Neoen reached the milestone of 1 GW of renewable energy under operation or construction in France. In December 2021, the Victorian Big Battery was commissioned. It is the largest battery in Australia and one of the biggest in the world, and it is now owned by HMC Capital. Also in December, the company also began construction of its largest wind farm, Goyder South Stage 1 in South Australia.
In 2022, Neoen signed Corporate Power Purchase Agreements totalling c.1 GW on assets in Australia, Finland, France and Sweden, including a baseload PPA with BHP to supply the Olympic Dam mine in South Australia. At the same time, the company began building the Fox Coulée solar plant in Alberta, its first in Canada.
The beginning of construction work on Blyth Battery in South Australia in late 2022 took Neoen over the 1 GW mark in storage capacity. The company then totalled nearly 6.6 GW in operation or under construction.
In March 2023, Neoen undertook a second capital increase, of €750 million, with the intention of increasing installed capacity by 50% and stepping up investment in storage. The company's expansion continued over the first half of 2023, with the start of construction of several wind farms and batteries, most notably in the Nordic countries and Australia. These projects bring Neoen's capacity in operation or under construction in Finland to more than 700 MW. In June, Neoen launched the construction of its first long-duration battery in Australia.
In early 2024, Neoen reached 1 GW of renewable energy capacity in the Nordics. In France, it is a consistent top winner in CRE calls for tenders in the ground-mounted power plants category, with awards amounting to 479 MWp over two years. In June 2024, Neoen topped 4 GW in operation or under construction in Australia.
In May 2024, Brookfield, a leading global investment firm, enters into exclusive negotiations with Impala and other shareholders to acquire a majority stake in Neoen. On December 30, Brookfield completed the purchase of a 53.12% stake in the company for 3.25 billion euros.
Following the Offer period, which ran from 13 February to 13 March 2025, Brookfield finalized the squeeze-out procedure on April 4, 2025. Since then, Neoen has not been publicly listed.
In 2025, Neoen continued its expansion in Europe with the construction of its first asset in Germany, and the inauguration of the largest solar farms in Portugal and Sweden.
In July 2025, Neoen signed four new long-term corporate power purchase agreements with SNCF Énergie, with durations ranging from 20 to 25 years. Starting January 1, 2026, Neoen will supply SNCF Voyageurs with 137 GWh of renewable electricity annually, produced by four of its farms with a combined capacity of 111 MWp.
In September 2025, Neoen signed a 10-year electricity supply contract with BHP, advancing Neoen’s total contribution to the energy transition in South Australia.
On 1st August 2025, Neoen completed the divestment of its Victorian assets in Australia to HMC Capital. The divestment formed part of the commitments made by Brookfield to obtain the regulatory approval from the Australian Competition and Consumer Commission, which was needed for Brookfield to acquire a majority stake in Neoen from Impala and other Neoen shareholders. The divestment included Neoen’s operating assets in Victoria as well as six projects in the development pipeline: Navarre Green Power Hub, Kentbruck Green Power Hub, Kentbruck Battery, Moorabool Battery, Loy Yang Wind, and Bulgana Battery Extension.
