Since 2016, grid disturbances have caused over 15,000 MW of unexpected generation loss from inverter-based resources (IBRs) — not due to equipment failure, but because inverter software was configured to protect equipment rather than stay connected. The core problem is a data management gap: IBR facilities are modeled at interconnection but inverter firmware and settings change constantly without updating planning models, creating a dangerous divergence between what the grid thinks generators will do and what they actually do. Three new NERC standards (PRC-028-1, PRC-029-1, PRC-030-1) take effect October 1, 2026, requiring disturbance monitoring, mandatory ride-through compliance, and ongoing post-event analysis. Most generator owners lack the clean, queryable data infrastructure needed to comply, with commissioning documentation often outdated and inverter settings untracked since initial interconnection.
