CTRASA Waste Incinerator Resumes Operations After Three-Week Maintenance in Andorra

CTRASA's waste incinerator in Andorra la Vella has returned to full operations following its annual three-week technical shutdown.

Over the past three weeks, CTRASA staff collaborated with 41 external specialist firms and more than 127 workers to inspect all equipment, carry out maintenance, and implement modifications aimed at boosting efficiency and performance. After completing the work, teams tested the upgrades thoroughly before reheating the facility, paving the way for normal activity. The plant's furnace is now operating smoothly.

This planned stoppage coincided with maintenance at FEDA's hydroelectric plant, scheduled for September and October to align with lower demand for electricity and heat. The timing allowed both facilities to prepare for higher winter loads while limiting any impact on supply.

CTRASA highlighted the maintenance's importance for ensuring long-term reliability, safety, and service continuity. Waste valorisation through cogeneration at the plant serves as Andorra's second-largest electricity source. In 2025, it generated 16.7 GWh of electricity and 17.5 GWh of heat, with the heat supplying the FEDA Ecoterm district heating network in the Central Valley.

Incineration targets only non-recyclable, non-reusable waste with energy recovery potential, diverting it from landfills as part of broader waste management.
