Located in North London, the plant is an essential part of LondonEnergy's operations for treatment of the collected waste streams from plant's various locations, allowing their discharge to the dedicated point.

The order was included in Valmet's third quarter of 2018 orders received. The modernization project is scheduled to be finalized during 2019.

Cooperation between the two companies started in 2012, when Valmet assisted LondonEnergy with five big boilers in their waste-to-energy facility by migrating the plant's obsolete PLC-based control to Valmet DNA. Initially, a multi-year plan was performed to update the control systems in the main boiler area while offering support services for legacy third-party equipment. A more recent project included improving the safety of LondonEnergy's steam turbines by using Valmet DNA-based vibration protection and analysis equipment.

Technical information about Valmet's delivery

Valmet will deliver a complete electrical and instrumentation package, which includes engineering and installation work for the field boxes associated with a new motor control center, low-voltage cabling, trace heating, instrument cabling and containment, as well as a replacement of the existing PLC control system with the advanced Valmet DNA automation system.
