Case Study: Mitsui Coal Holdings achieves 99.99% uptime and KPI reports in seconds with Amazon Web Services

MCH Delivers Key Performance Indicator Reports in Seconds vs Days using AWS

Mitsui Coal Holdings (MCH) is the Mitsui & Co. holding company for investments in 14 Australian coal mines, managing over AU$2 billion in assets with a small finance team. MCH’s legacy on‑premises financial reporting system was unreliable (about 85% uptime), prone to source‑code issues and outages after a 2016 data‑center flood, and required labor‑intensive manual KPI reporting and error‑prone data collations that prevented timely analysis.

MCH chose SAP S/4HANA deployed on AWS with PwC as implementation partner and went live in four months, running on Amazon EC2 and S3 in the Asia Pacific (Sydney) region. The move delivered 99.99% uptime, automated KPI reports in seconds instead of days, fewer errors, faster quarterly reporting for the parent company, improved real‑time analytics across mines, and scalable infrastructure to extend SAP benefits to other business units.
