Why do this project? This project is required to address the functional and technical concerns of the incumbent generation dispatch modeling tOOl. The 2008 Technical Asset Review identified Opsym as an overall high risk due to underlying b...
AI summary This project addresses risks in the incumbent generation dispatch modeling tool (Opsym), identified as high risk due to scalability and functionality issues. Manual mitigation is unsustainable, and loss of Opsym would cause inaccuracies in real-time pricing and failure to meet Northeast Power Coordinating Council reporting requirements, a North American Electric Reliability Corporation mandate.
2. Executive Summary The assessment performed during this review has rated the overall system risk as High . The following risks were identified: - Potential revenue loss. A loss of the Opsym application could result in inaccurate RTP valu...
AI summary The executive summary highlights high system risk due to reliance on the Opsym application, which could cause revenue loss, operational inefficiencies, and regulatory non-compliance. Risks include inaccurate RTP valuations, scheduling failures, and inability to meet NERC and UARB requirements. NSP IT recommends developing a technology strategy, SLA, business continuity plan, and maintenance protocols.
4.7.Top Issues with the Application The following have been identified as the priority issues with the application or its environment. - Opsym does not accurately model NSPI's electrical system, in particular, the various transmission cons...
AI summary The application faces critical issues: Opsym's inability to model transmission constraints, lack of a relational database, security vulnerabilities, reliance on Excel spreadsheets, network dependency, and limited support. These flaws hinder accurate modeling, data retrieval, system reliability, and compliance with ISO requirements.
5. Risks Assessment The following risks have been identified with the Opsym environment. - Potential revenue loss. A loss of the Opsym application could result in inaccurate RTP valuations or non-optimal fleet dispatch scenarios, both situ...
AI summary The risks identified include potential revenue loss due to inaccurate RTP valuations and dispatch scenarios, operating efficiency loss from difficulty in producing dispatch schedules, and regulatory risks related to failing to meet NERC and UARB requirements.
OVERALL SYSTEM RISK RATING: High The High risk rating is derived from the moderate probability of a significant Opsym issue and the major impact of an Opsym issue on NSP operations.
AI summary The high system risk rating for Nova Scotia Power is attributed to a moderate probability of a significant Opsym issue and its substantial impact on operations.
