CLog 3.0: COOP and WITRON launch third building stage

Norwegian grocery retailer COOP Norge SA and WITRON have maintained a successful and trusting partnership for more than a decade. This collaboration is embodied in the full-range logistics center near Gardermoen Airport in Oslo. Covering 84,000 square meters, the facility currently supplies 1,200 stores with more than 13,000 different dry, fresh, and frozen items. At its core is WITRON’s OPM system, featuring 42 COM machines operating across all temperature zones. In early November 2025, COOP signed a contract for the project CLog 3.0 to expand its highly automated facility by adding 12 additional COM machines along with all upstream and downstream logistics technology. This third building stage will increase the total COM machine count in the logistics center to 54 and boost throughput to 690,000 picks per day.

The distribution center, equipped with WITRON solutions OPM, DPS, and CPS, and a fully automated shipping buffer, has been productive since 2014 (building stage 1). The second building stage, completed in 2022, added 11 COM machines. 

Now, as part of the third stage, another 12 COM machines will be integrated and become operational in 2028. Installation will largely take place within the existing building infrastructure, following WITRON’s holistic design concept. This approach enables COOP to respond quickly and flexibly to future growth in store numbers, throughput, or product range. 

“WITRON systems have helped us save millions of euros annually. It was therefore clear that we would realize this expansion together with WITRON and their leading logistics technology,” explained COOP project manager Ståle Nersund.

The expansion with twelve additional COM machines – increasing the total to 54 – will take place during ongoing operations and cover all temperature zones - dry goods (+18 °C), fruit and vegetables (+2 °C / +7 to +12 °C), and frozen food (-25 °C). It also includes upstream pallet and tray storage (136,000 additional storage locations / 27 additional stacker cranes), extended conveyor systems, five additional depalletizers, and three more stretch-wrappers. 

This investment enables COOP to pick an additional 120,000 store-friendly cases daily, raising throughput to 690,000 picks per day – ensuring efficient and sustainable customer service despite rapid growth.
