Biedronka has equipped more than 2,300 stores across Poland with photovoltaic installations developed in cooperation with GreenYellow, taking the combined capacity of the programme to 117 MWp. The systems are expected to produce approximately 113 GWh of electricity annually, with the power used directly at the individual retail properties.
The programme represents a large-scale conversion of existing retail roofs into electricity-generating infrastructure. Grocery stores have relatively consistent energy requirements from refrigeration, lighting, ventilation and other equipment, allowing much of the electricity produced during operating hours to be consumed directly on site rather than drawn from the grid.
Biedronka’s solar network has expanded rapidly in recent years. The retailer began with installations at only eight stores in 2022 before extending the programme across a growing proportion of its Polish estate. By July 2025, more than 2,000 locations had been equipped, with the latest expansion taking the total beyond 2,300.
The financial impact is becoming increasingly visible. During 2025, photovoltaic installations serving Biedronka stores and logistics properties generated 96.1 GWh of electricity. The retailer estimates that the resulting reduction in externally purchased power lowered its electricity expenditure by PLN 57.6m during the year.
Solar generation is being combined with other measures designed to control energy consumption across the property portfolio. Biedronka has introduced digital monitoring and building-management systems at a large number of locations, while energy-efficiency measures reduced consumption by a further 32 GWh during 2025. GreenYellow finances, develops and operates the photovoltaic infrastructure under a long-term cooperation model, reducing the need for Biedronka to provide the initial investment for individual installations.
With Biedronka operating close to 3,900 stores in Poland by mid-2026, photovoltaic systems are now installed at well over half of its domestic locations. The 117 MWp portfolio demonstrates the amount of generating capacity that can be created by using roof areas distributed across a large network of existing retail properties.
The programme provides a wider example for commercial property owners and occupiers looking to reduce energy costs and dependence on externally supplied electricity. Rather than limiting renewable-energy investment to new developments, Biedronka’s rollout shows how existing retail buildings can be progressively upgraded and turned into a distributed network of energy-generating properties.
