U.S. energy infrastructure developer LS Power has been selected to deliver a new grid infrastructure project in California’s Bay Area, with a strong focus on improving substation connectivity and reliability.

The project, awarded by the California Independent System Operator, will connect key substations through a new 230 kV underground transmission link, strengthening the network between Silicon Valley Power’s Northern Receiving Station and Pacific Gas and Electric’s San José B substation.

While the development includes approximately seven miles of underground transmission infrastructure, its primary role is to enhance the performance and resilience of critical substations, which act as central nodes in the regional electricity network.

According to LS Power, the project is designed to “strengthen power infrastructure and improve electric grid reliability across the Bay Area.”

By reinforcing the connection between substations, the project will help reduce congestion, improve load balancing, and ensure more stable electricity delivery in one of California’s most energy-intensive regions.

The investment, estimated between $150 million and $200 million, supports growing demand in the San José area, driven by population growth, electrification, and the expansion of data centres and technology infrastructure.

Once completed, the infrastructure will be owned, operated, and maintained by Pacific Gas and Electric, further integrating it into the wider regional grid.

Substations play a critical role in modern power systems, managing voltage transformation and directing electricity flows across the network. Strengthening interconnections between these assets is increasingly important as grids become more complex and incorporate higher levels of renewable energy.

Undergrounding the connection between substations also adds resilience benefits, particularly in urban environments, by reducing exposure to extreme weather and minimising land-use constraints.

The project reflects a broader trend in the energy sector, where utilities and developers are prioritising substation upgrades and interconnections to improve reliability and support the transition to cleaner, more distributed energy systems.
