About Us

TDI, the developer of the Champlain Hudson Power Express, is a leading independent transmission provider currently serving the North American market. TDI focuses on using HVDC technology to develop projects that deliver, safe, reliable power in an environmentally and aesthetically responsible manner.

TDI believes that in order for power markets to work efficiently and effectively there must be sufficient transmission to allow the lowest-cost generation to flow to meet the needs of consumers. In today's market, acute transmission bottlenecks are causing prices to rise, hindering renewable generation projects, and impeding the efficient operation of AC systems. Utilizing best-in-class HVDC technology, not only do our projects deal with these three critically important issues, they do so in an environmentally responsible manner with minimal visual impact to communities. These buried lines increase the electric grid's safety and reliability, while providing hardened infrastructure that is less susceptible to damage from natural disasters.
