High-Voltage Complexity: Execute 4 large-scale studies (115kV–325kV) assessing new load impacts on Avangrid’s transmission network, ensuring compliance with Avangrid Standardized Interconnection Requirements (SIR), Maine’s Level 4 interconnection standards, and NERC reliability standards.
Regional Variability: Navigate differing interconnection rules across New York and Maine, requiring adaptive technical and regulatory workflows.
Scaled Deadlines: Manage concurrent CESIR applications and system impact studies under aggressive timelines.
Action
Performed thermal, voltage, and stability analyses for all 4 projects, identifying transmission line upgrades, substation modifications, and protection system enhancements.
Developed protection & control upgrade plans (breakers, bus configurations, transformer relays) and SCADA/communication protocols for seamless integration.
Produced project-specific cost models (materials, labor, equipment)
Centralized one-line diagrams, facility assessments, and CESIR documentation in a shared repository for Avangrid teams.
DST Value Addition
Delivered system specifications, an assessment of existing attachment facilities, and preliminary cost estimates for required upgrades.
Provided a detailed analysis of necessary transmission line or substation upgrades and a cost breakdown for materials, labor, and equipment.
Developed a final report, including thermal, voltage, and stability assessments, recommended system enhancements, and a finalized facility study meeting all compliance standards.
Provided grounding study analysis for existing and greenfield substations and switching yards.
