Sempra Signs 20-Year Petrobras Deal Amid Grid Expansion

Sempra Infrastructure, a subsidiary of Sempra (NYSE:SRE), finalized a 20-year agreement on September 14 to supply approximately 0.8 million tonnes of liquefied natural gas annually to Petrobras. This deal marks the first time a South American entity has entered as an LNG customer for the company, diversifying its buyer base and reinforcing a dual-coast strategy that serves both the Atlantic and Pacific basins. The contract secures long-term demand for the Port Arthur LNG Phase 2 project in Texas, a facility that is still years away from operational status.

The agreement underpins a broader growth trajectory that includes a stronger-than-expected second quarter and a surge in electricity demand within the state. Sempra’s Q2 2026 GAAP earnings per diluted share increased to $1.21 from $0.71 in the prior year, while adjusted earnings rose to $1.16 from $0.89. These financial improvements coincide with a significant increase in power consumption in Texas, where the ERCOT grid recorded an all-time peak load of 91 gigawatts in July.

Port Arthur Expansion Details

The Petrobras contract is tied to the Port Arthur LNG Phase 2 project, which received a positive final investment decision in September 2025. The project will add two liquefaction trains, bringing online in 2030 and 2031, with total capacity expected to reach approximately 13 million tonnes per year. This expansion nearly doubles the total throughput of the Port Arthur facility to roughly 26 million tonnes annually. Because the first ships are not expected until 2030, this contract represents a long-term bet on global energy demand rather than an immediate source of cash flow.

Texas Grid Demand Surge

Sempra’s utility subsidiary, Oncor, is responding to a genuine demand surge in the Texas market. Regulators have endorsed more than $7 billion in new transmission spending to support the addition of 16 gigawatts of capacity. Furthermore, a newly approved interconnection process, known as Batch Zero, could make roughly 44 gigawatts of large-load requests eligible for service. This potential load exceeds the grid’s current 31-gigawatt peak by more than 140%, highlighting the scale of infrastructure investment required to meet future needs.

Capital Plan And Risks

Funding these expansions presents a significant financial challenge, with Sempra’s five-year capital plan calling for roughly $65 billion in spending. To manage this burden, the company is pursuing asset sales, including a deal to sell 45% of Sempra Infrastructure Partners to KKR affiliates and a separate sale of its Ecogas México unit. Both transactions are currently working through final approvals. Additionally, the company faces operational risks from currency and inflation swings tied to its Mexican operations, which contrast with the steadier regulated returns seen in its Texas and California utilities.

Management has raised full-year GAAP EPS guidance to a range of $5.02 to $5.55, maintaining its long-term earnings growth target of 7% to 9%. However, key California rate decisions covering 2028 remain pending before regulators, meaning a portion of future earnings depends on approvals outside the company’s direct control. As noted by GN auto stocks/energy-stocks: natural gas demand, the company is balancing immediate utility growth with long-term liquefaction projects, creating a complex risk profile that spans multiple geographies and sectors.
