FIFA Confederations Cup, focusing on the energy supply to
the metro areas in which the games would take place. Several
of the system reinforcements planned to be in service for the
World Cup were not yet concluded in time for the Confederations Cup. Thus, the energy import levels of these metro areas
were reduced, resulting in the need for increased output levels
of the more expensive local thermal generation. Although this
measure incurred higher costs, it ensured an extra level of security in the event of transmission line outages (N-1 and N-2).
The Confederation Cup was a success, since no major incidents in the electric system were detected (and a further success
as the Brazilian soccer team won the tournament). The rehearsal
had shown that the World Cup action plan was headed in the
right direction. In continuation of the extensive preparations,
the Brazilian ISO issued a report in July 2013 classifying the
system facilities that were strategic for the energy supply of the
host cities for the World Cup games, as follows:
✔ Group 1: strategic substations with influence on the
performance of the supply grid to the host cities
✔ Group 2: bulk-power system substations, beyond those
in Group 1, with direct impact on the event venues
✔ Group 3: existing substations located in the electrical
path between the bulk-power system and the transmis-

sion and distribution grids, up to the substations that
directly supply the stadiums
✔ Group 4: substations included in the restoration cranking path.
In addition to these groups, other substations were
selected and ranked based on their exposure to system events
that could interrupt supply to the game venues. Figures 6 and
7 show the single-line diagrams of the transmission grid supplying the game venues and also the main airports in the two
largest cities, Rio de Janeiro and São Paulo.
Several system upgrades that had been determined necessary two years earlier in the WG assessment report were
being implemented simultaneously and in a expedited manner. However, the WG identified difficulties in the execution
of some of the projects, noting the resulting delays and the
significant chances of these facilities not being in service
in time for the World Cup. Hence, the WG determined the
impact of the delays and reviewed the plan based on the
reinforcements that effectively would be in service in time
for the event. The WG also took into consideration the most
recent load forecast, among other system data.
The revised and final system studies performed for
every host city determined action plans that met the FIFA
