Case Study: Mälarenergi AB achieves a virtualized, more reliable IT environment with Oracle License Management Services

Mälarenergi Improves IT Environment with Proper Licensing That Supports Virtualization

Mälarenergi AB, a city‑owned power and heating provider in Västerås, Sweden serving 160,000 customers, runs a large Oracle Database estate with twelve business‑critical environments including its ERP system. The IT team discovered it was underlicensed after buying single Oracle Database licenses from vendors who lacked full knowledge of Oracle’s licensing rules, risking compliance and limiting its ability to virtualize infrastructure.

Working with Oracle License Management Services, Mälarenergi corrected its licensing model to support a virtual cluster instead of one license per physical server, allowing databases and additional applications to move into a shared virtual environment without buying new licenses. The change delivered better performance, increased operational reliability, and a more manageable IT environment—prompting the company to favor Oracle for future solutions.
