TDI - a Blackstone Portfolio Company

Transmission Developers develops unique clean energy transmission projects in an environmentally responsible manner. Our projects use proven high-voltage direct current (HVDC) cable technology to link trapped generation resources such as wind, hydro and other renewables with markets that are seeking new sources of clean power. By installing our projects underground or underwater we avoid the negative impacts of overhead transmission. These buried lines increase the electric grid’s safety and reliability, while providing hardened infrastructure that is less susceptible to damage from natural disasters.
