Paso de los Toros, Uruguay — 2019/2022
In July 2019, UPM decided to build its second pulp mill in Uruguay, in Paso de los Toros/Pueblo Centenario, in the department of Durazno. It is one of the largest pulp mills in the world, with a production capacity of 2 million tonnes per year.
Over the course of the project, UPM has entrusted Ingener with the following works:
– Engineering, construction and commissioning of the 150 kV connection and metering point (PCyM) that will connect the mill to the national power grid. The works also include the expansion of the Bonete B 150 kV substation.
– Design, execution and commissioning of the temporary power network, including its subsequent management, operation and maintenance. This scope included the supply and installation of 12 substations of 33/0.4 kV, 1.0 MVA each, a 33 kV internal power network, low-voltage distribution, distribution boards and backup generator sets.
– Process electrification and instrumentation works, including the supply, laying and termination of more than 350 km of MV and LV cables and the installation of more than 8,000 instrumentation hook-ups.
– Power electrification works, including the installation of a 7-bay 150 kV GIS substation within the mill, the laying and termination of 7.5 km of 150 kV cable, the installation of 4 transformers of 150/33 kV, the installation of 90 MV switchgear cubicles (33 kV), the installation of more than 1,500 motor control and protection panels (MCCs), among others.
– Process piping works, including the supply and installation of more than 500 tonnes of piping (mainly stainless steel) and the execution of more than 100,000 weld inches, all under quality certification to European standards.
– Complete HVAC and industrial ventilation system for the mill, including the installation of more than 400 tonnes of metal ductwork, the installation of 25 chillers for chilled-water generation and 140 air handling units.
– Installation of the mill’s two steam turbines, each rated at 200 MW
– Perimeter lighting for the mill, including more than 14 km of road lighting with 160 W LED luminaires, for a total lighting installation of approximately 60 kW, including a remote control system for monitoring and managing the lighting system.
– Outdoor lighting system for the entire mill, including road lighting and lighting of the wood yard using 30-meter-high monopoles with 550 W LED floodlights, among others. This lighting system totals almost 200 kW of installed capacity, including a remote control system for monitoring and managing the lighting system.
