Parnaiba IV

Parnaíba IV

Maranhão, Brazil

56 MW

Energy security has become a priority in Brazil as the electric power supply has not kept pace with robust demand growth. Hydropower is the dominant source for electricity production, accounting for approximately 70% of Brazil’s installed capacity. However, droughts and diminishing reservoir levels in recent years have threatened capacity sufficiency. With supply deficits projected to occur by 2016, new thermal plants are needed to meet the country’s growing power requirements. By integrating natural gas production with power generation, ENEVA’s Parnaíba Complex in Brazil’s northeastern state of Maranhão provides access to a guaranteed fuel supply and reliable energy production.
