Açu power station

From Global Energy Monitor
(Redirected from Açu power project)


The Açu power station was a proposed 2,100 MW coal-fired power station which was to be based on imported coal and located in the Açu Super Port near São João da Barra, Rio de Janeiro state, Brazil. The coal plant has subsequently been replaced by a natural gas-fired project.

Brazil's MPX Energia SA (now Eneva) received initial approval for the plant in 2008. However, the plant was passed over in favor of lower-cost competitors at Brazil's August 2013 EPE energy auction, and in October 2013 the Brazilian environmental authority INEA revoked a request to renew the plant's license, partly due to delays in development of port and "mineroduct" facilities that were crucial for the plant's success, and partly due to tougher state and federal laws regulating greenhouse gas emissions.[1][2]

In March 2014 Valor Económico reported that Eneva remained interested in pursuing a coal- and natural gas-fired power project at the Açu port, but in September 2014 port operator Prumo Logística (formerly LLX) revoked its contract with Eneva, citing Eneva's failure to honor contractual conditions.[3] In April 2015, Prumo Logística entered into a new agreement with the Bolognesi group for construction of a natural gas-fired plant at the Açu Super Port. Eneva sought judicial intervention, and in July 2015 the Second Circuit Court of São João da Barra issued an injunction calling for INEA to reconsider its revocation of Eneva's license to operate at the port.[4]

The Açu coal plant project was ultimately abandoned, but Prumo Logística has since teamed up with BP and Siemens to develop the gas-fired GNA I and GNA II power stations in the same location.[5]
