The 2014 FIFA World Cup took place between June 12 and July 13, 2014, in São Paulo, Brasilia, Belo Horizonte, Cuiabá, Salvador, Recife, Fortaleza, Natal, Manaus, Porto Alegre, Curitiba and Rio de Janeiro. The operational safety of the electrical service to the host cities was one of the challenges that an event of this size imposed to the entire Brazilian electric sector.

The preparation of activities related to electrical studies for the 2014 FIFA World Cup started in August 2010, when the Ministry of Mines and Energy - MME, based on the decision of the Comitê de Monitoramento do Setor Elétrico - CMSE (Monitoring Committee of the Electricity Sector) created a work group for the 2014 World Cup - GT Cup 2014 by MME Ordinance No. 760 on August, 30 of 2010. The Group was created with the objective of conducting the activities necessary for the preparation and monitoring of 2014 Cup Action Plam, focusing on the supply of electricity to the twelve capitals that were Cup host cities.

Throughout 2014, was issued a set of Technical Notes for each host city, which:

• reported a diagnosis of the service provided to the metropolitan area of the host cities during the event;
• defined the relevant facilities to guarantee the electrical safety of the state capitals that hosted the 2014 FIFA World Cup;
• defined the facilities operation and the BIPS operation centers differentiated plans;
• presented the guidelines for theBIPS operation during the event.

The first set of Technical Notes was issued on February 2014 and identified possible actions to be performed in each host city before and during the event, with and without works whose completion date was May 2014. The goal was to ensure the supply of electricity with different safety standards, as adopted at special events, in line with the provisions of Resolution CSME 001/2005.

Later, other Technical Notes were issued contemplating a system’sdiagnosis considering the works that effectively would be in operation for the event, as well as setting Electro-energetic programming and the BIPS operation for the 2014 FIFA World Cup. In these Technical Notes were listed, for each host city, actions identified as necessary, such as additional thermal generation, energy restrictions and adjustments and / or new Special Protection Systems (SEPs), so that the host cities had their main cargoes preserved in situations of simple loss and ensure outstanding performance also in situations of double losses.

Some key points concerning the supply to each host city were highlighted, such as:

• The situation of the city as the requirement of FIFA to supply the stadium with redundancy in terms of distribution.
• The situation of the supply system to the host city for possible voltage problems and loading in the normal operating condition.
• The situation of the supply system to the host city as service to the Network Procedures requirements for simple contingencies (N-1 criterion) in Network Operation. The specific conditions required for them to be fulfilled were listed.
• As for service to different safety standards (N-2 criterion), mitigating operational measures required were listed for each city for most of the double contingencies were met, or that would cause selective non-priority loads cut.

During the period of the 2014 FIFA World Cup, the supply systems to the twelve host cities were operated under different security criteria, which resulted in thermal dispatch lifting by electric reason and Emergency Control Schemes installation specific to this period. The interventions were limited to transmission lines and equipment of the facilities that endangered the integrity of equipment and human lives. It should be highlighted that this strategy was considered adequate and the BIPS outperformed the standards established by the Network Procedures.

With regard to system operation, ONS coordinated preparatory actions involving their own teams from different areas and including in this process all operating agents of the host cities. Directed studies, recovery tests, drills and elaborate normative documents were performed. During the time when the mathches occured, reinforcement teams of ONS’s electric operation planning departments were defined, protection, meteorology, electro-energetic programming, real-time operation, maintenance Control Supervision Systems and infrastructure of Operation Centers, standardization, post-operation and communication. In addition to these internal actions, there were sent guidelines to operating agents and distribution, owners of facilities in the affected areas, to provide special arrangements for operation, ensuring locally assisted operation 24 hours a day.

During the competition, the operation performed in the course of each game was examined by the post-operation team, with specific published reports, in which aspects of continuity of supply and load behavior were analyzed influenced by change of the energy consumption habits of society.
