Brazilian natural gas pipeline prices flip

  • Spanish Market: Natural gas
  • 21/08/23

The landscape for natural gas pricing in pipelines has shifted in Brazil in the past year, with what was once the lowest-priced gas in a pipeline network now ranking as the most expensive.

Contracts on the TAG network — Brazil's most extensive system in the northeastern coastal states which initially had the lowest gas prices after the market opening in 2021 — rose to reach prices similar to the TBG system in the south this year. NTS' gas contracts offered the least expensive gas among the three major pipeline systems.

After the first year of market liberalization in Brazil, prices for gas on the TAG pipeline averaged $11.86/MMbtu, while TBG gas was priced at an average of $14.24/MMbtu, using an average of Argus daily prices for February 2022. Gas prices on the NTS pipeline averaged $13.50/MMbtu in the same period.

Gas price levels have changed for the three networks since then, with new contracts coming into effect in the last year and price indexing changing in the regions. TAG gas prices were the highest among the three networks in July, averaging $12.484/MMbtu, closely followed by TBG's $12.316/MMbtu. Gas prices on the NTS pipeline became the lowest among the three networks, at an average of $10.944/MMbtu.

Distributors on the TAG pipeline have signed new gas contracts since then with higher Brent crude indexation. The four contracts signed by distributors in the TAG pipeline's region this year range from 13-14.4pc of Brent, while gas contracts on the NTS pipeline have remained largely unchanged since 2021 — before the Russia-Ukraine conflict drove natural gas prices up across the world.

Some of the most influential gas contracts on the NTS pipeline belong to natural gas distributor Naturgy, to distribute gas in Rio de Janeiro state. But these contracts, which were supposed to end after 2021, have been under an injunction and frozen since 2022.

The legal conflict originated when Petrobras increased its gas prices by 50pc when the 2021 drought forced the company to increase LNG imports for power generation. Naturgy and other distributors went to court to protest the hike, calling it an abuse of economic power. Many of them were able to get injunctions to maintain gas prices as they were under contract at the time, but all other distributors have since then reached an agreement with Petrobras.

Naturgy and Petrobras are close to reaching a deal to settle the dispute, the companies said in a public forum in Rio de Janeiro a few weeks ago. All other companies that signed deals included a passive payment for the time the injunctions were in effect, a market source said.

Naturgy's public concession for natural gas distribution in Rio de Janeiro is set to expire in 2027, which makes the resolution of the judicial conflict particularly necessary for the company to consider new contracts and renewing its concession. Other distributors in the NTS pipeline's region have signed 10-year gas contracts with Petrobras.
