Brazil rebuilt power procurement on hybrid auctions after a rationing crisis
After 2001–02 rationing, Brazil made distributors buy through centralized auctions; 31 auctions (2004–2010) contracted about 57,000 MW of new capacity.

the move
Brazil's 2001–2002 electricity rationing exposed a broken expansion model. The government elected in 2003 rebuilt the framework: distribution companies had to procure energy for captive consumers through public auctions in a regulated contracting environment.
The standard design combined a descending clock auction with a final sealed pay-as-bid round; because total supply remained above demand by a factor unknown to bidders, the second phase pushed prices further down. The first such auction ran on 30 November 2004 and contracted more than 17,000 average MW.
Between 2004 and 2010 Brazil ran 31 auctions for existing and new energy, contracting roughly 57,000 MW of new capacity for delivery from 2008 to 2015 with 15–30 year contracts. The World Bank's 2011 study credits Brazil as the regional leader in moving from bilateral contracting to sophisticated multi-buyer, multi-seller procurement.
why it works
- Mandatory auctions replaced opaque bilateral deals for regulated consumers.
- The two-phase design balanced price discovery with final cost pressure.
- Long contracts gave investors certainty while competition set the tariff.
what transfers
Two-phase auctions that first discover, then squeeze price — with a deliberately unknown oversupply margin — can force cost disclosure that bilateral negotiation never reveals.
what came after
Brazil's hybrid auction design became the regional benchmark in Latin America and a core case study in the World Bank's 2011 procurement report; the framework still underpins Brazilian energy contracting through A-5/A-3 auctions for new capacity, as documented in CEMIG's SEC filings.
