Abstract: The management of mission-critical operational technology (OT) platforms such as Energy Management Systems (EMS) that have exceeded their design useful life poses a major technical and strategic challenge for power System Operators (SO), particularly during prolonged technology transitions. This paper aims to assess the reliability and sustain the operational continuity of an EMS platform under obsolescence, through an integrated framework of seven strategic components supported by a quantitative formulation that combines availability, redundancy, bounded dynamic risk, and degraded service states modeled by a numerically solved four-state Markov chain. The approach is applied to the real case of the EMS platform of a System Operator (SO) in an emerging economy, currently transitioning toward a new EMS expected by 2027. Measured results include a baseline availability of 99.91 %, a mean time to repair (MTTR) of 2.7 h, and the rationalization of more than 20 % of historian signals; the Markov-based assessment yields an effective availability of approximately 99.91 %, and the dynamic risk model quantifies risk-exposure reductions in the range of 29–55 % per failure mode, while a threshold-based economic assessment establishes the cost-effectiveness condition of the plan. Collectively, these measures strengthen the operators ability to maintain high availability and reduce risk exposure during the transition window, and provide a structured basis for prioritizing mitigation actions and supporting technical and managerial decision-making aimed at preserving the secure operation of the power system.
