Łódzka Kolej Aglomeracyjna implements ecological energy and water savings

Łódzka Kolej Aglomeracyjna (ŁKA) is expanding its ecological initiatives to manage energy and water resources more efficiently. The company utilizes a closed-loop water system in its train wash facilities, which includes a private wastewater treatment plant, allowing nearly 80% of the water used to be recycled back into the technological process.

To reduce electricity consumption, ŁKA employs several technical solutions. Its technical facilities are powered by a photovoltaic farm that had produced 265 MWh by the end of October. For train operations, the company uses recuperation systems that recover up to 30% of the energy used during braking. Additionally, the Sensum system assists drivers by indicating optimal acceleration and braking moments to improve energy efficiency and punctuality.

Regarding renewable energy sources, ŁKA reports that 70% of the traction energy required to power its trains is expected to come from renewable sources by 2026, up from 50% two years prior. The carrier is the first in Poland to join the Zielona Kolej program and holds a Green Energy Certificate awarded by PGE Energetyka Kolejowa.
