# Energy-efficiency upgrade to Złocieniec’s district-heating system

The Złocieniec heating company plans construction and refurbishment of heating substations and installation of a photovoltaic system to improve the municipal heating system’s energy efficiency.

Further works detail, price, participation requirements and the meaning of procedure code 1.1.1 could not be verified. The snapshot gives a deadline of 30 October 2026 at 08:00 UTC.
