Itaqui power station

(Redirected from MPX Itaqui power project)


Itaqui power station is a 360-megawatt (MW) coal-fired power plant operated by Eneva S.A. (formerly MPX Energia) in São Luís de Maranhão, Brazil. Originally known as UTE Termomaranhão or MPX Itaqui, the plant now goes by the official name UTE Itaqui or UTE Porto do Itaqui.

Diferencial Energia, original developer of the Itaqui project, sold generation rights in March 2007 to Brazilian power holding company EDB [1], which in turn established a 50-50 partnership with Brazilian mining company MPX Mineração e Energia. MPX bought EDB's stake and assumed 100% ownership shortly after Brazil's October 2007 A-5 energy auction, in which the Itaqui plant won a contract to produce an annual average of 315 MW of power over a 15-year period.[2]

In October 2012, the government environmental agency IBAMA (Instituto Brasileiro do Meio Ambiente) granted the plant its operating license[3], and in February 2013 the electrical agency ANEEL (Agência Nacional de Energia Elétrica) authorized the plant to begin commercial operations, with an installed capacity of 360 MW. [4]

In September 2013, MPX Energia S.A. rebranded itself as Eneva S.A.[5] As of January 2021, Eneva S.A.'s two main shareholders are BTG Pactual and Cambuhy, each with a 22.93% stake.[6]

Eneva's coal-fired power plants, including Itaqui and the Porto do Pecém power station, generated a profit for the first time in 2018. However, CEO Pedro Zinner, in a May 2019 interview with Brazil Journal, said that Eneva had no further plans to invest in coal and that he expected coal to play a diminishing role in the company's footprint over time.[7] Eneva's current electricity generation concession for the Itaqui plant expires in December 2026.[8]

In an October 2020 interview with Capital Reset, Eneva CEO Pedro Zinner reiterated the company's commitment to phasing out new investment in coal-fired power plants, but left open the possibility of continuing to operate the Itaqui plant beyond 2026 if Brazilian demand for electricity exceeds supply from other sources.[9]


In 2008, MPX reported that it had invested US$698 million in capital expenditures in the project and had received US$160 million in loans.[10] In March 2009, the Inter-American Development Bank (IDB) announced that it gave US$50 million in loans to the project and would arrange further loans for the project from international banks, including Banco Nacional de Desenvolvimento Econômico e Social (BNDES).[11][12]

Environmental impact

In mid-2016, the Federal Public Prosecutor's office for Maranhão state accused the Brazilian environmental agency Ibama of having significantly and inappropriately raised emissions limits for the Itaqui plant after the plant repeatedly released excessive levels of sulphur dioxide and other pollutants. Citing dangers to public health resulting from Ibama's tripling of the emissions limits, the Public Prosector's office called for the plant's license to be suspended or modified to bring emissions back into compliance with levels established in the plant's original Environmental Impact Assessment. A spokesperson for plant owner Eneva denied the Public Prosecutor's charges.[13]
