The Gladstone Power Station is the largest power station in Queensland, Australia. The world-class facility has six coal powered steam turbines that can generate up to 1,680 MW of electricity. Since its inception in 1976, the power station has played a vital role in the growth of the Gladstone region, providing customers with safe, reliable and low cost electricity. After privatization of the plant in 1994, it has been operated by NRG Gladstone Operating Services on behalf of the joint-venture participants, the two majority owners being Rio Tinto and NRG Energy.
Expand IT/OT integration
Gladstone Power Station has been utilizing Asset Suite for managing assets, work, materials and procurement since 1998. With NRG embarking on major improvement projects across their businesses, they wanted to upgrade existing systems to the latest technology in order to lay a solid foundation for future developments. This approach was in line with their long-term strategy to virtualize all business-critical applications and extend IT/OT integration to encompass more work groups and processes.
Upgrade to Asset Suite 9
NRG leadership decided that the best way to meet their goals was to upgrade their existing Asset Suite installation. Current modules would gain significant performance improvements on the new platform and wider integration could be achieved with the addition of new modules. As with any modifications to live production environments, extensive planning and preparation was required to minimize work disruptions and downtime. Trinoor, ABB’s software services partner, worked tirelessly with NRG’s Information Services team to ensure that the implementation would meet the project’s aggressive timeline and budget.
Ease of upgrade
Asset Suite 9 has been designed with ease of implementation in mind. The upgrade was pre-built on a virtual machine (VM) clone of the production system. This allowed for testing of all installation and upgrade scripts before deployment, and also eliminated potential errors caused by environmental differences between the test system and the live system.
The upgrade scripts themselves have also been improved. The scripts now run directly with SQL, which shortened installation time from days to hours. This, combined with the ability to quickly refresh the virtual environment, meant that the number of test runs could be increased. If problems occurred, it was simple to roll back to a working version and resume testing from that point.
