System Impact Studies

System Impact Studies

Enerzinx specializes in delivering comprehensive System Impact Studies (SIS) that ensure renewable energy projects and large-scale data centers connect to the grid safely, reliably, and cost-effectively. Our expertise lies in applying advanced grid modeling tools and proven engineering methodologies to evaluate project impacts on transmission systems, helping clients navigate complex interconnection requirements and avoid costly delays. With a strong focus on technical accuracy and regulatory compliance, we provide actionable solutions that enable faster project approvals and optimized designs.

We partner with developers, utilities, and ISOs/RTOs to deliver accurate study reports and robust interconnection strategies, ensuring that every project is grid-ready from concept to commissioning. Our SIS services cover the full spectrum of studies, including the following.ย 

Grid Interconnection & Stability Studies
Evaluates normal and N-1/N-1-1 grid conditions to ensure reliable interconnection without overloading equipment.
Assess system behaviour during disturbances to verify voltage, frequency, and rotor angle stability.
Determines fault current levels to validate breaker ratings and protective device adequacy.
Measures system strength at the POI to ensure stable inverter operation and control performance.
Verifies relay coordination and protection schemes for safe fault detection and clearing.
Evaluating project performance under grid disturbances.
Ensuring PSSE and PSCAD models accurately reflect plant behaviour.
Analyzes inrush currents and switching transients to mitigate energization impacts on the grid.
Confirms the plantโ€™s ability to meet voltage control and power factor requirements under all conditions.
Identifies required transmission upgrades and provides high-level cost estimates for interconnection.
Evaluates risks of the plant unintentionally energizing a de-energized grid section and proposes mitigation measures.
Assesses the ability to deliver full output to the grid under various system conditions without curtailment.
End-to-end assistance with ISO/TSP interconnection requirements and technical approvals.
