Customers of southern Rio Grande do Sul state natural gas distributor Sulgas were surprised by regional regulator Agergs' decision to grant an increase in the fixed rate portion of the tariff by 33pc following the sale of the company to gas trader Compass.
The gross margin charged by Sulgas to its regulated consumers on top of the gas fee was increased from R0.2821/m³ to R0.3756/m³ starting this month. That cost includes a profit to be shared among shareholders.
The gross margin increase is the opposite of what the market expected and may point to more distributors increasing fees in 2023. Sulgas, which used to be mostly owned by Rio Grande do Sul state, was sold on October 2021 to gas trader Compass — owned by energy group Cosan — for R927mn ($174.5mn).
Compass owns a 51pc stake in Sulgas with the remaining shares belonging to Commit, a new company created with Compass and Japanese company Mitsui.
Industrial gas consumers in Brazil's south told Argus that they were surprised by the increase, as they expected expenses and fees to be trimmed after the state government lost control of the company.
Sulgas had a 2021 profit of R72mn, a 8.5pc drop from the prior year, on total revenue of R1bn, which was up by 32pc. Gas sales to industrial consumers accounted for 58pc of revenue. The increase in revenue came despite gas sales volumes dropping by 14.6pc, from 1.98mn m³/d to 1.69mn m³/d.
No new gas for the southern region
The highest costs for gas at the end of the first year of the Brazilian gas market's liberalization were in Rio Grande do Sul and its neighboring states. Limited pipeline capacity in the region and a lack of local gas production meant the state's three distribution companies were not able to procure gas from producers other than Petrobras, leading to the higher prices.
The average gas price for the southern region was $14.888/mnBtu in 2022. The average cost for the northern region was $13.339/mnBtu and the southeastern region gas price averaged $13.442/mnBtu.
Prices in Petrobras' contracts this year increased from 11pc of the Brent oil price to 16.75pc of Brent. The Sulgas contract signed under this increase resulted in an average price of $18.3209/mnBtu this year, above the average regional and national prices.
