They are intended to help ensure the safe and stable integration of renewable and decentralized energy systems with traditional power networks. ### What changes are expected in the upcoming Requirements for Generators (RfG) regulations? *add* *remove* The upcoming RfG 2.0 is expected to update technical requirements to support grid stability with more renewables, including storage integration, bidirectional charging and grid-forming capabilities. UL Solutions closely monitors these updates. ### What are the common challenges that companies face in grid code compliance, and how does UL Solutions help companies address them? *add* *remove* Key challenges include complex regulations, multi-country requirements and project timelines impacting ROI. UL Solutions addresses these through gap analysis, training, grid studies, simulations and inspections. With experience across 200+ installations (~9 GW), we can help streamline testing time and manage costs. ### How does UL Solutions stay updated with the constantly changing grid code regulations? *add* *remove* UL Solutions stays up to date through active participation in regulatory bodies, industry partnerships and continuous research.
