Work History
Sr. Lead Engineer
PJM Interconnection - SPMS/GMDS
02.2024 - Current
- Maintained and enhanced the generator mapping synchronization process across EIA, PJM Planning, Operations, and Markets databases, ensuring seamless data integrity and operational alignment across critical business units
- Worked closely with Transmission owners to identify and map behind the meter generation in their areas
- Worked closely with Generator owners to guide them through NERC MOD-032 process using PJM Gen Model application. Also worked with GOs to ensure their modeling data is acceptable by NERC
- Served as project manager for the Gen Model application (NERC MOD-032 compliant) drastically improving data exchange between generator owners and PJM engineers, assuring data quality and process compliance.
- Served as project manager for Dynamic Data Manager (NERC MOD-026/027/033 compliant) - aiming to improve dynamic data exchange processes for ease of tracking, accessing, and managing dynamic data.
- Led and facilitated cross-divisional coordination meetings between Operations and Planning, driving alignment on model assumptions, study methodologies, and real-time system condition integration
- Supported development of RTEP and MMWG models assuring high quality standards and timely deliveries on each step
- Mentored and trained engineering staff on advanced power system modeling techniques, PSS/E application, NERC compliance workflows, and overall PJM functions elevating department-wide analytical capabilities
