Marubeni Corporation has launched a retail power business aimed at corporate clients in Texas through its wholly owned subsidiary SmartestEnergy US LLC (SEUS). SEUS, which has historically focused on the deregulated power markets of the Northeastern U.S., is now expanding its footprint to establish coverage across all U.S. states with deregulated power markets, including the fast-growing Texas market.

Why it matters

Texas is experiencing rapid population and economic growth, leading to a robust increase in power demand. The state is also witnessing rapid expansion in renewable energy deployment, creating a need for supply-demand balancing and battery storage services. By leveraging its trading and risk management capabilities, SEUS sees Texas as a key strategic region for future growth.

The details

SEUS has opened a new office in Houston, Texas, where it will place locally hired market specialists. The company aims to provide high-value-added services aligned with customer needs in Texas and to expand the supply of renewable energy to high-tech companies and data centers, drawing on the expertise of its parent company SmartestEnergy Limited as a major power retailer for data center operators in the United Kingdom.

• Marubeni launched the retail power business in Texas in February 2026.
• SEUS was founded in 2019 and has been growing its customer base by more than 100% annually.

What’s next

SEUS plans to leverage its trading and risk management capabilities to provide high-value-added services aligned with customer needs in Texas and to expand the supply of renewable energy to high-tech companies and data centers.
