Why G99 & G100 Expertise Is Critical for Renewable Energy Success

With grid connection constraints now the primary obstacle to UK’s Net Zero targets, understanding EREC G99 and G100 requirements has become essential for renewable energy project delivery. Developers face increasingly complex technical standards, rigorous compliance testing, and varying DNO interpretation across solar, battery storage, and wind projects.

This comprehensive training provides practical knowledge to navigate the complete grid connection compliance journey—from initial application through commissioning and testing—preventing costly delays and rejected applications that jeopardize project viability.
