Energy producers and utilities operate some of the most demanding automation environments in any industry. Whether managing power generation, transmission, distribution, or refining operations, the control systems at the heart of these facilities must run continuously and reliably. Many of these systems were built on DEC VAX, Alpha, and OpenVMS platforms in the 1980s and 1990s — programmed in FORTRAN and C by engineers who understood both the code and the physics of the processes they controlled.

These legacy systems contain decades of finely tuned process logic that governs everything from turbine sequencing and load balancing to emissions monitoring and safety interlocks. Replacing them outright would mean losing irreplaceable operational knowledge and introducing unacceptable risk to critical infrastructure. Salem Automation provides energy companies with a proven modernization path that preserves every line of proprietary logic while eliminating hardware risk — all with zero production downtime.
