Case Study: Les Mousquetaires achieves €2M energy savings in 6 months with Deepki

Detecting four million euros of savings on the energy budget in just 6 months

Les Mousquetaires, a European retail group operating 3,092 stores and 100 production and logistics sites with an annual energy bill of €200M, engaged Deepki to reduce energy consumption, cut its energy budget by at least 1% year‑on‑year, and establish an automated, global energy management approach. Deepki was brought in to provide a data‑driven energy management solution combining automated data collection and ESG reporting capabilities.

Deepki implemented automatic invoice and energy data collection from supplier portals, data reliability checks, clustering of store profiles, and machine‑learning anomaly detection to generate concrete, prioritized action plans. In just six months Deepki helped detect over 200 energy‑saving actions totalling €2M (excl. tax) in identified savings, met and exceeded the customer’s targets, and automated long‑running invoice collection (178,881 invoices collected since 2016).
