G99 Compliance Study
Our G99 Compliance Study proves your energy assets support grid stability during disturbances. Using advanced dynamic modeling, it ensures regulatory compliance, prevents connection delays, and secures your project's successful energization.
Modern electrical grids are increasingly reliant on distributed generation and storage to maintain overall system stability. To prevent cascading blackouts during network disturbances, grid operators mandate that all new assets actively support the grid—rather than simply disconnecting. A G99 Compliance Study is a dynamic engineering assessment utilized to prove exactly how resilient and responsive a project’s generation assets—whether utilizing modern power electronics or traditional synchronous generators—will be during severe network deviations.
Accurately demonstrating grid resilience is the absolute bedrock of regulatory approval and successful project development. Failing to meet G99 requirements directly halts a project's energization. By providing stakeholders with a scientific evaluation of regulatory risk, we ensure that facility designs are built on verified performance capabilities. This data-driven clarity is essential for securing final connection agreements and confidently advancing a project to the energization phase without the threat of unexpected operational restrictions.
Under the G99 framework, generation modules are classified as Type B, C, or D based on their registered capacity and connection voltage, with each tier demanding a progressively rigorous set of specific compliance studies. We tailor our advanced dynamic modeling approach to meet your project's exact categorization requirements. By constructing a complete software-based digital model of the local network and integrating highly specific asset data, we mathematically simulate how your plant responds to extreme grid events. Our comprehensive assessments evaluate all critical regulatory criteria, including Limited Frequency Sensitive Mode (LFSM-O/LFSM-U) responses, steady-state Active and Reactive Power (PQ) capabilities, dynamic voltage control, Fast Fault Current Injection (FFCI), and Fault Ride Through (FRT) survivability. This targeted engineering approach delivers the highly accurate, definitive proof of compliance required by the Distribution Network Operator (DNO) to safely connect and energize your project.
