SAO PAULO, Nov 29 (Reuters) - Brazilian power company Eletrobras said on Tuesday it has decided to temporarily halt its migration to "Novo Mercado," a segment of the local stock exchange with stricter governance rules, due to adverse economic and market conditions.

Centrais Eletricas Brasileiras SA, as the company is formally known, said in a securities filing that in 2023 it would reassess the migration process, part of its post-privatization plans. (Reporting by Gabriel Araujo; Editing by Louise Heavens)
