MATERIAL ANNOUNCEMENT Jaguara Plant: Interim injunction in Supreme Court Provisional Remedy Action 3980 revoked

Cemig (Companhia Energética de Minas Gerais), a listed company with securities traded on the stock exchanges of São Paulo, New York and Madrid, in accordance with CVM Instruction 358 of January 3, 2002, as amended, hereby informs the Brazilian Securities Commission (CVM), the São Paulo Stock Exchange (BM&F Bovespa S.A.) and the market in general as follows:

The interim injunction given in Action for Provisional Remedy No. 3980/DF has been lifted.

Action for Provisional Remedy 3980 was brought by Cemig's wholly-owned subsidiary Cemig GT (Cemig Geração e Transmissão S.A.) against the federal government in the Federal Supreme Court (STF).

In Action 3980 Cemig GT applied for suspension, until final judgment of the ordinary appeal before the Federal Supreme Court (STF), of the effects of the judgment by the First Section of the Higher Appeal Court (STJ) given in Application for Mandamus No. 20.432/DF.

The judgment in case 20.432 had denied award of an order to maintain Cemig GT in possession of the concession for the Jaguara Hydroelectric Plant under the initial terms of Concession contract 007/97.

On March 21, 2017 the STF website giving the updated position in legal actions stated:

" the interim remedy previously given has been revoked, with issue of an order to submit the case to the Procurator-General of the Republic, for statement of opinion on Application for Mandamus No. 34.203. "

Cemig will keep its stockholders and the market timely and appropriately informed on the progress of this case.
