The city of Sosnowiec has awarded a public contract to Hekla Energy for the supply of renewable electricity to all municipal buildings and public infrastructure. The transition, set to begin on 1 January 2026, will cover administrative services, healthcare facilities, cultural centres and city-affiliated companies. The municipality will incur no investment expenditure under the agreement.

A break with the coal-based industrial legacy

Once a centre of Poland’s mining and metallurgical industry, Sosnowiec is turning the page on its coal-dependent past. Located in the Dąbrowa Basin, the city is leveraging energy partnerships to accelerate its modernisation. The contract with Hekla Energy ensures electricity sourced exclusively from certified Polish wind, solar and biogas sources.

Entities included in the deal range from the municipal waste management company to the waterworks and the local public transport operator. In the healthcare sector, several facilities will be powered by renewable electricity, including the city hospital, an outpatient medical centre and the Milowice health clinic.

Energy supply extended to cultural institutions

The city’s educational and cultural institutions will also benefit, including the Zagłębie Theatre, the “Egzotarium” education centre, the Sielecki Castle Art Centre, the Schoen Palace Museum, the Gustaw Daniłowski Municipal Public Library, the Jan Kiepura Cultural Club and the Open Culture Stop. The Zagłębie Sports Park is also among the facilities listed for green energy supply.

Hekla Energy, which claims a client portfolio of over 17,000 across Poland, supplies only certified renewable energy from local sources. The company offers guarantees of origin, additional energy-related products and pricing described by city officials as transparent.

No infrastructure cost for the municipality

The city will bear no infrastructure or transition costs under this agreement. Hekla Energy provides flexible and continuous energy supply, with no service interruption for the covered public sites. According to the provider, this model allows local governments to benefit from environmental and economic gains without increasing their operating budgets.

The reduction in the number of smog days in Sosnowiec—from over 100 to fewer than 20 in the past decade—is frequently cited by city officials as evidence of ongoing change. The energy partnership with Hekla is part of this trend, deploying zero direct-emission electricity to meet the demands of a modernised urban administration.
