For the fourth time in its history, since it came into operation in 1984, the Itaipu plant ended the semester producing over 50 million megawatts/hour (MWh). The milestone of 50.16 million MWh was reached at dawn on June 30. All this energy would be sufficient to meet the planet's demand for electric power for 19 hours; and Brazil’s, for 39 days.
 
  
 
It has been the second best performance for a period of six months in 34 years of operation, only behind the first semester of 2016, when the hydroelectric plant produced 51,637.234 million MWh. It was the year of the world record, when Itaipu produced over 103.1 million MWh. No other hydroelectric plant has produced as much in one year.
 
Itaipu has also surpassed the mark of 50 million MWh in one semester in 2012 and 2013. "For an atypical year, with low water levels and with the World Cup, which requires special production measures, ending the semester with this performance is considered exceptional", said Itaipu executive technical director, Mauro Corbellini. The hydrologic inflow for the month, for example, has been the worst for the last 34 months of June.
 
During the semester, the water use rate for power generation reached 98.76%, an exceptionally high amount. "The pursuit of efficiency, by doing more with less, is permanent. Seven of the ten 10 days of highest production at Itaipu, over the last 34 years, occurred in 2018", emphasized Corbellini.
 
Also during the semester, the availability of the generating units was 96.8%, and the forced unavailability - an index that measures the unexpected unavailability of generators due to equipment or human failure -, was only 0.11%. The operating failures in real time, on the other hand, with impact to equipment availability, were zero.
 
Itaipu was also prominent during this year in an atypical situation that occurred in the National Interconnected System (SIN). On the afternoon of March 21st, when practically the entire Northeastern Region of Brazil had no power, the generating units of Itaipu remained interconnected to the national system, contributing to the SIN’s stability and the mitigation of the problem.
 
During FIFA’s World Cup, the National System Operator (ONS) has also required special criteria for the SIN operation, since the consumption on the days Brazil plays, oscillates rapidly, with abrupt drops and increases. 
 
According to Itaipu’s Brazilian general director, Marcos Stamm, "whether during atypical periods such as the World Cup or during normal times, the plant has always been essential to efficiently and responsibly meet the demand of the Brazilian and Paraguayan electrical systems". He stated, "This is the main mission of the binational plant, but in addition to producing energy, the plant has been expanding actions and initiatives to ensure the socioeconomic growth of the entire Western Paraná region, as the neighboring country has done in its region of influence”.
