Brazil renewables try to clear transmission queues

Brazil's renewable power sector is fighting to avoid fines when giving back previously granted authorizations build projects, as a long queue of projects that might not come to fruition is clogging access to transmission lines.

Brazil's generation project approval process first authorizes the projects and then queues them for access to transmission lines. In 2021, the government announced it would end transmission and distribution subsidies for renewable power projects authorized after March 2022, causing several new projects to rush requests to beat the deadline. Too many projects were approved, however, as it would be impossible for all of them to be built and connected to the grid in a timely manner.

Brazil now faces a lack of access points for new projects, with some projects on the access point list unlikely to even materialize because of changes in company expansion plans or other factors. This situation will soon hinder Brazil's capacity to effectively expand power generation, even for projects that seem likely to be built.

More than 20 generation companies had been expecting to meet with power regulator Aneel's general-director Sandoval Feitosa last week to discuss the proposal, but the gathering was canceled mere minutes before the appointed time. Another meeting has yet to be scheduled.

The power sector cannot keep up with the 150GW authorized for a four-year period during the "gold rush" to avoid the end of subsidies, as power generation expands at a 5GW-7GW/yr rate, according to wind power association Abeeolica's president Elbia Gannoum. There are structural factors, both domestically and internationally, keeping some of the projects in the transmission access queue from going on line, while others have sold their power in the free market and have not been able to access the transmission lines because of the queue, she said.

Renewable generators are suggesting projects that are not able to move forward be allowed to give back their connection authorizations without paying fines. The sector has been calling this proposal "the day of atonement," a reference to the Jewish Yom Kippur holiday where observers atone for their sins. Likewise, electricity regulator Aneel would forgive fines from generators for requesting authorizations for projects that will not be built.

The "day of atonement" measure would interest most of the renewable and transmission sectors, but market participants say Aneel and mines and energy ministry MME might not be so keen.

Aneel has been studying a new tender format to avoid this problem in the future. The tender would end the queue format and give a financial incentive for projects to be completed after being authorized, since they would have to pay to access transmission lines.
