Northeast Utilities, NStar file request to build transmission line to Canada
The filing requests that the commission approve the assignment of firm transmission rights on a new participant-funded transmission line to Hydro-Quebec (HQ) to enable the development of a purchase power agreement. The proposal calls for Hydro-Quebec to deliver low-carbon hydroelectric power to New England over a new high voltage direct current (HVDC) tie line between northern New England and Quebec. Northeast Utilities (NU), NStar and HQ Energy Services US (HQUS), a wholly owned subsidiary of Hydro-Quebec, have signed memoranda of understandings to develop this transmission project on an exclusive basis. Planning is under way with HQ subsidiary TransEnergie to develop the specifics of the new tie line. The proposed transmission line would connect the Des Cantons substation in Quebec with a point to be determined in southern New Hampshire, where NU's Public Service of New Hampshire operates. The proposed line will be designed to transmit at least 1,200MW of power. NU, NStar and HQUS have also begun discussions on the specifics of the longer-term power purchase agreement that would ensure the line is utilized to bring low-carbon energy to benefit New England customers. The intent of the parties is to create a structure that allows additional New England customers to participate, not just those of NU and NStar.
