LS Power Transmission

“Competition leads to lower costs and more efficient projects for consumers.”

Paul Thessen, President, Development

Leading the Way in Transmission Sector Competition

LS Power transmission projects strengthen America’s power system and help deliver energy resources to tens of millions of homes and businesses across the country. We have developed and constructed more than 660 miles of transmission infrastructure and have ~400 miles of additional projects in the planning stages. In the process we lower consumer costs, provide jobs and give back to the communities we serve.

To date we have been selected to build transmission projects by a majority of the Independent System Operators across the country. This includes winning the first competitive solicitation in both PJM Interconnection (PJM) and Midcontinent Independent System Operator (MISO), which together serve more than 100 million people across more than 25 states.

LS Power is a leading advocate for transparent and competitive processes to plan, build and own transmission infrastructure. While competition now exists for certain projects in certain regions, it remains limited and should be expanded to benefit consumers.


LS Power was selected by the New York Independent System Operator (NYISO) as the most efficient and cost-effective solution in New York’s largest competitive transmission project to date.  The Central East Energy Connect project includes upgrades between Marcy and New Scotland of nearly 100 miles of double circuit 345 kV transmission and two new gas insulated substations.



LS Power was selected as one of eight entities by the Public Utility Commission of Texas (PUCT) to build and own a portion of the 2,300 miles of new transmission infrastructure required to access wind generation resources in Texas. LS Power’s project was completed in 2013, ahead of schedule, below budget and at the lowest cost per mile of any provider.



LS Power was awarded the first competitively solicited transmission project by PJM Interconnection. LS Power’s solution was deemed lower cost and environmentally superior to other options proposed, and established a first-of-its-kind project cost cap to protect electricity consumers from paying for cost overruns – a new, consumer-focused approach.



LS Power was chosen by the California Independent System Operator (CAISO) to build and own the Harry Allen to Eldorado 500 kV transmission line, which went into service in August 2020. The selection report concluded that LS Power’s proposal included “… more robust capital/construction cost and ROE caps that should result in lower costs and present less risk compared to the proposals of the other two project sponsors, thus benefiting ratepayers.”



LS Power was chosen by the Midcontinent Independent System Operator (MISO) for its first competitive project under FERC Order 1000. The selection report stated that LS Power’s proposal “… exhibited the best balance of high-quality design and competitive cost, best-in-class project implementation and top-tier plans for operations and maintenance.”



In 2014, LS Power developed the One Nevada Transmission Line (ON Line) as the first-ever connection between NV Energy’s northern and southern load centers, which is critical to ensure the reliability and integrity of the Western grid. The ON Line also supports renewable energy by bringing wind and solar power generation in Wyoming, Idaho, and Nevada to California and other major-load centers.
