EBC Energy Seminar: New Transmission –
The Key to Renewable Energy Integration in New England

Green Line Overview
2
o 500 kV DC transmission system with transfer capability of 660 MW or more (e.g.,1200 MW)
o Manageable distance (~ 140 miles submarine cable, 1 foot in diameter)
o Interconnected between Maine Yankee Substation in Maine and K Street Substation in South Boston at 345 kV with Option to interconnect to locations south of Boston.
o Gives market access to Maine, northern NH, and Maritimes renewable resources.

Green Line Team Experience
3
o Proposed by New England Independent Transmission Company, LLCo Principals are the main developers behind the Neptune and Hudson Projects
o Neptune Project: $600+ million, independent HVDC transmission system linking New Jersey and Long Island – www.neptunerts.com – Operational – Completed July 2007. On time and on budget.
o Hudson Transmission Project: from New Jersey to West 49th St in Manhattan. Selected by NYPA and under development – www.hudsonproject.com

New England REC Demand/Supply Outlook
4
o New England’s demand for renewable resources through aggressive RPS programs, particularly in Massachusetts and Connecticut, is a driver of renewable resource development in New England
o New resources from northern New England and eastern Canada will be needed to meet demand
o Transmission will need to be developed to support the growth
o A copy of the full report by Energy Security Analysis, Inc. is available on the Green Line web site at www.greenlineproject.com/news/industry/
Integration with NE Grid
5
o Reliability Upgrades to the ISO-NE
Grid accomplished with the Maine
Power Reliability Program (MPRP)
will support the Green Line
o Interface constraints at Orrington
are relieved allowing energy to flow
from northern Maine and eastern
Canada south to Wiscasset
o MPRP studies show Green Line
compatible with upgrades
o Studies show Boston’s K Street Sub-
station able to absorb 600 MWs
Green Line Development History
6
o Green Line Concept – Spring 2006 – Question # 1 – Who pays?
o Submitted to ISO-NE with FERC Filing December 2006
o FERC Order Finding NEITC “independent and capable” February 2007
o 2007 - ISO-NE Scenario Analysis – Transmission needed to support imports
from beyond the load centers.
o Order 890 – Attachment K – Economic Needs Assessment – December 2007
ISO-NE compliance filing with FERC
o December 2007 – HVDC Day – Nine proposals.
o March 2008 – Economic Study Requests – 12 Proposals – 5 HVDC projects
o Attachment N-K Working Group convenes – March 2008
o 2008 Cost Allocation for “Economic Projects” opened to question
o Late 2008: HQ-NU-NStar file with FERC for approval of 1200MW
transmission line from Quebec to southern New Hampshire
o Transmission bundled with Generation in a “package deal”

o NU-NStar-HQ FERC filing a “Game Changing” step in the right direction:
o It is “a deal” as requested by Mass regulators encompassing supply, and
transmission to southern NH
o It envisions a power purchase agreement (PPA) which we agree is the
key to financing infrastructure
o “Supplier pays,” sort of. We all know the cost of the transmission line is
embedded in the deal so, ultimately, “consumer pays.”
o The only thing needed to make this proposal a BIG step in the right
direction is COMPETITION.
Green Line Today
8
o Competition in Transmission and associated renewables development
o Put states in the position to drive energy & environmental policies
o Whether under regional or federal RPS requirements, we are massively
increasing the demand for renewables, and for transmission.
o As always, if we are going to spend scores of billions of dollars on transmission, it
will be useful to spend that money pursuant to open, competitive and intelligent
Requests for Proposals.
o Should Massachusetts opens its 1,200MW procurement to competition – as we
think it will to assure that the opportunity to supply renewables (RPS and/or low
carbon) is open to all – it will receive a number of compelling bids:
1. The Quebec-NU-NStar Proposal: 1200 MWs of mostly Canadian, large
scale hydro delivered to NH then to load centers.
2. A Green Line proposal: 1200MWs of mostly Maine renewables (with NB
energy via beefed up interconnections) delivered to Boston and the Cape.
3. An “offshore” wind proposal (from mostly offshore Massachusetts
suppliers?)
o Let the best project – most buildable, best credit, best mix of renewables – win!
