GreenYellow, a French energy company backed by the Ardian fund, plans to spend over €100 million (about PLN 430 million) in Poland over the next three years on new photovoltaic installations, energy storage systems (BESS) and energy efficiency projects. The company is also looking at potential acquisitions to accelerate its expansion in the region.
The investment will be delivered mainly through the as-a-service model, where GreenYellow finances, builds and operates the installations, while clients pay a fixed fee for the energy or services. This approach removes capital expenditure (CAPEX) and technical risk from the customer’s side, enabling faster decision-making for large-scale rollouts.
GreenYellow already manages 145 MWp of solar projects in Poland, most of them for retail and telecom operators. The new funds will help scale up existing programmes and enter new industrial segments.
Solar boom in Polish retail
Retail chains have become the main driver of solar adoption in Poland. By December 2025, Biedronka, the country’s largest supermarket chain, had around 2,300 rooftop PV installations with a total capacity exceeding 100 MWp. These systems generate roughly 100 GWh a year. The entire programme is run on a PV-as-a-service basis by GreenYellow.
Another major client is Decathlon, which is building PV carports at 14 locations across 12 cities. The combined capacity reaches 3 MWp, producing about 3 GWh annually and cutting CO₂ emissions by over 2,000 tonnes per year. – Retail in Poland has moved past pilot projects and into large-scale, repeatable deployments. Even small energy savings at such scale translate into significant cost and environmental benefits. The as-a-service model allows this without tying up internal capital – said Rolando Furlong, CEO of GreenYellow Europe.
Industry joins the race
Manufacturing companies are also accelerating their decarbonisation efforts. With energy costs becoming a key competitive factor, more industrial players are investing in on-site renewables and efficiency measures. GreenYellow is already active in the food, automotive, automation and wood processing sectors.
One example is a 653 kWp PV system at CMC’s plant in Andrychów and a solar installation that powers Orange Polska’s Warsaw data centre. – For many manufacturing firms, energy cost is now a decisive factor for competitiveness. Investing in renewables and efficiency is no longer an option but a necessity – added Furlong.
Beyond solar: storage and efficiency
New projects increasingly pair solar with battery storage to optimise self-consumption and manage peak demand. GreenYellow is also modernising HVAC and refrigeration systems, and deploying cogeneration and process heat solutions. The total value of such projects under analysis or already being executed exceeds €40 million.
The company was founded in 2007 and is majority-owned by Ardian. It operates in 15 countries across four continents.
