Brazil’s state-owned utility Origem is activating underground natural gas storage facilities to stabilize energy supply amid rising grid demand and infrastructure strain. The move signals a strategic pivot in the country’s energy resilience strategy.
- Origem activated underground gas storage in Campos Basin to support thermal generation in early 2026.
- Gas storage capacity reached 1.4 billion cubic meters, with 180 million cubic meters injected in Q1 2026.
- Hydropower reservoir levels dropped 22% in Southeast Brazil, increasing reliance on gas.
- Power prices in São Paulo and Rio de Janeiro rose up to 37% during peak demand.
- Natural gas futures (NG=F) increased 12% month-over-month in February 2026.
- Government committed $2.3 billion to grid modernization and storage by 2028.
Origem, Brazil’s largest electric utility, has begun drawing on underground natural gas storage capacity in the Campos Basin to support thermal power generation during peak demand periods. The initiative, launched in February 2026, targets a 35% increase in gas availability for power plants during dry seasons when hydropower output declines. This follows a 22% reduction in reservoir levels across the Southeast region, exacerbating supply risks. The underground storage network, operated under the National Gas System (SNG), holds approximately 1.4 billion cubic meters of gas. Recent injections totaled 180 million cubic meters in the first quarter of 2026, up from 110 million in the same period in 2025. These reserves serve as a buffer against supply disruptions, particularly during periods of low rainfall that affect hydroelectric generation. Market indicators reflect growing sensitivity to Brazil’s energy dynamics. Natural gas futures (NG=F) rose 12% month-over-month in February, while crude oil (CL=F) and Brent crude (BZ=F) posted gains linked to regional energy demand. Power prices in São Paulo and Rio de Janeiro surged by as much as 37% during peak hours in March, illustrating the financial impact of supply constraints on the electricity market. Stakeholders across the energy sector, including LNG importers, grid operators, and regional regulators, are reassessing infrastructure investments. The move underscores systemic pressure on Brazil’s energy infrastructure and raises questions about long-term planning, particularly as renewable integration accelerates. The government has announced a $2.3 billion investment in grid modernization and storage expansion by 2028.
