Approval of ANEEL’s regulation had been long-awaited, but the agency had delayed the process, which was first floated in 2019. After the conclusion of the public consultation, debate resumed in April, prompted by a request for review by board member and reporting director Fernando Mosna.
There had been fears that a new request for review, made by ANEEL director Willamy Frota that month, would put the decision back on hold, drawing concern from the national energy storage trade association Associação Brasileira de Armazenamento de Energia (ABSAE).
Decision follows ‘years of debates and regulatory construction’
This week, ANEEL said Frota “largely agreed” with the regulation as set out by Mosna, pertaining to models for the operation of ESS assets, remuneration and revenue stacking, and contract terms for network access.
However, Frota made a proposal on charges for network use that was approved by a majority of the ANEEL board.
