Case Study: China Resources Gas Group achieves faster billing, high-quality service for 20M customers and major cost reductions with Oracle Exadata

China Resources Gas Group Calculates Billings Faster, Delivers High Quality Services to 20 Million Customers, and Reduces Significant Operating Costs

China Resources Gas Group Ltd. (CR Gas) is one of China’s leading gas utilities, supplying 13.3 billion cubic meters of gas annually to 20.9 million customers across 205 city gas projects. Rapid expansion through organic growth and acquisitions, plus strict government requirements for air-quality, energy-conservation and safety, meant CR Gas needed faster application deployment, better customer-data management, improved service quality, and higher equipment-safety standards across a growing subsidiary network.

CR Gas consolidated 13 database servers from 200+ subsidiaries onto a single customer information system powered by Oracle Exadata and Oracle RAC, enabling high-performance mixed-workload processing and eliminating single points of failure. The move cut CPUs by 70%, floor space by 80%, power use by 78% and cooling by 60%, accelerated billing and meter-reading, integrated mobile and third‑party e-payments, and improved analytics to identify expired equipment—delivering faster service to millions of users while meeting availability, compliance, and cost-reduction goals.
