This Technical Brochure presents findings of the C2.23 WG on the general procedure and practices adopted by 18 transmission system operators (TSOs) over 5 continents, namely: Europe, Asia, Australia, North America and South America.

It also presents the major challenges encountered and the key lessons learnt during restoration of the disrupted power grid in recent major disturbances.

From these findings, a set of recommendations for follow-up work is made.
