Orlen Completes Kleczew Solar Expansion to 250 MW

• Orlen’s Kleczew solar farm expansion to 250MW makes it Poland’s biggest in-company PV asset—turning reclaimed mining land into clean power for tens of thousands, accelerating decarbonisation.

Poland’s Orlen has completed the expansion of its Kleczew solar photovoltaic farm to 250 MW, making it the largest solar asset in the company’s renewable portfolio. The project is located on reclaimed post-mining land in central Poland and is part of Orlen’s broader energy-transition strategy to boost renewable generation.

Orlen said the expanded facility is expected to generate clean electricity sufficient for tens of thousands of households while cutting carbon emissions and supporting Poland’s gradual move away from coal. The company is also continuing investment across solar, offshore wind, hydrogen, and energy storage, highlighting how former mining regions are increasingly being converted into renewable energy hubs as European decarbonisation targets tighten.

How does Orlen’s expanded 250 MW Kleczew solar project impact Poland’s decarbonisation?

• Adds substantial new clean generation capacity: Expanding Kleczew to 250 MW increases Poland’s renewable electricity supply, reducing reliance on coal-fired generation during peak and base-load periods.
  
• Lowers power-sector emissions: Each megawatt-hour produced by the solar farm displaces emissions from fossil generation, contributing to Poland’s progress toward decarbonising electricity generation—the sector with the largest decarbonisation challenge for many economies.
• Accelerates transition away from coal-linked regions: Building on reclaimed post-mining land helps shift the economic and environmental footprint of former coal areas toward low-carbon infrastructure, aligning decarbonisation with just-transition goals.
  
• Supports grid decarbonisation and energy security: Additional domestic renewable output can reduce the need for higher-carbon and potentially imported electricity, improving resilience as demand grows and carbon-intensity targets tighten.
• Enables portfolio-scale renewable growth: As a major anchor asset within Orlen’s renewable portfolio, Kleczew strengthens momentum for further scaling of solar and complementary technologies (such as storage and flexible generation), which are key to maintaining renewable reliability.
• Improves the investment signal for faster renewable build-out: Large, completed projects help reduce investor uncertainty and can speed permitting, procurement, and supply-chain learning across the market—factors that influence how quickly Poland can expand renewables.
  
• Frees space for system-wide optimisation: More solar generation allows system operators to refine dispatch strategies, integrate grid upgrades, and plan for balancing needs—work that is central to achieving deep decarbonisation rather than isolated projects.
  
• Reinforces EU-aligned decarbonisation pathways: Expansions like Kleczew contribute to Poland’s ability to meet EU climate and renewables targets, where electricity-sector decarbonisation is a major measurable pathway.
• Demonstrates practical land-use decarbonisation: Repurposing post-mining sites into energy assets can lower conflict over new land take, supporting smoother scaling of renewables that is often constrained by land-use and social acceptance.
• Strengthens the long-term pathway to net-zero: While one project won’t fully decarbonise Poland, adding 250 MW of low-carbon generation meaningfully advances the cumulative capacity build required for sustained emissions reductions over the coming decade.
