Brazil expects its natural gas-fired power plants will have operating costs between R215-600/MWh ($42.36-118.21/MWh) for the next 10 years.
The country's 10-year plan for the energy sector, PDE 2031, sets expected operating costs (CVU) depending on factors such as plant flexibility and energy cycles utilized.
State-run energy research bureau Epe, which helps the government plan for power auctions, publishes a preliminary version of the plan each year. Epe estimates a R215/MWh CVU for natural gas at completely inflexible thermal plants, a R259/MWh CVU for natural gas utilized at plants with 30pc inflexibility and a R600/MWh CVU for natural gas burned by simple cycle thermal plants. A plant's flexibility is the level of contractual obligation to generate energy, or the amount of power that must be dispatched regardless of the cost for the system.
The PDE 2031 also sets the estimated CVU for LNG at R385/MWh for completely flexible plants and at R303/MWh for plants with 30pc inflexibility.
Epe's calculations are based on 2021 Henry Hub prices.
The document also foresees increases in capital expenditure related to natural gas, compared with the previous year's estimates. The PDE 2031 sets the expected spending for simple cycle natural gas at R3,600/kW, a 5.9pc increase, and at R5,300/kW for combined cycle natural gas, a 3.9pc growth. LNG capital expenditure is estimated at R4,300/kW, up by 4.9pc compared with the previous year, and sugarcane-sourced biogas' spending was set at R8,000/kW, a 6.7pc increase.
