eneva Parnaíba Complex < 58 > We maintain in Santo Antônio dos Lopes, Maranhão, the Parnaíba Complex, composed of the thermal power plants of natural gas generation Parnaíba I, Parnaíba II, Parnaíba III and Parnaíba IV, in addition to two projects under development: Parnaíba V and Parnaíba VI. In total, the contracted capacity is 1.9 GW, of which 1.4 GW is already in operation, and the generated energy is sent entirety to the SIN, in the North subsystem, within the ACR. The complex is one of the largest thermal parks of natural gas power generation in Brazil and a pioneer in the use of the integrated Reservoir-to- Wire model. With gas produced in fields located around the plants, which allows reduction of costs and losses in the transportation of fuel, the energy generated has more competitive prices and lower environmental impact. In 2021, we completed the heavy works of Parnaíba V, with the completion of the Backfeed Qde SE 500 KV, the commissioning of a Water Treatment Plant, hydrostatic tests completed and in the process of cleaning and pre-operational tests in boilers and turbine mounted and in the connection phase of pipes. Thus, Parnaíba V entered its instrumentation and control phase, commissioning begins in 2022 and the start of commercialization of its 385 MW of energy is scheduled for August 2022 Parnaíba Complex and Transmission Line Substation in Santo Antônio dos Lopes, MA In Parnaíba VI, we signed contracts in 2021 with the turbine manufacturer and the executor of the works. Construction will begin in 2022, with commercial operation scheduled for 2024 and, at CCR, in 2025. Parnaíba VI will represent the cycle closure of Parnaíba III, with 92.5 MW added to the Parnaíba Complex. Parnaíba II recorded an operational incident in a turbine and operated, for 30 days, with half its capacity. After the necessary adjustments, the plant returned to normal levels of generation capacity.
