Buried cable may cost more; however, since there is less power loss on a DC line, in the long term, Allegheny will have more profit with HVDC. Below is a combined table from the Economic Assessment of HVDC Project in Deregulated Energy Markets (April 2008) . Of the New York Regional Interconnect (NYRI) Case Study. 190 Miles from upstate NY to southeast NY immediately close to the NY city.

If the PATH project were able to achieve the same results, the extra cost of the HVDC could soon be recouped since Allegheny will make more than 2.5 times the profit if they use HVDC versus HVAC.
