Here in New Hampshire, the leaves have turned.  What hasn’t changed is that the environmental review of the Northern Pass proposal remains stalled while the project developers – Northeast Utilities (and its subsidiary Public Service Company of New Hampshire) and NSTAR – seek a new route for the northernmost 40 miles of the project.  It’s a disgrace that the U.S. Department of Energy (DOE) has so far refused to use the developers’ significant delay to assess the nature and extent of New England’s need for Canadian hydropower and to develop an appropriate plan to bring that power into the region, as CLF and others have been requesting since April.

While DOE is in a holding pattern, CLF is continuing to fight for a fair and comprehensive environmental review of the Northern Pass project.  Earlier this month, CLF filed new comments with DOE, supplementing the detailed comments we filed in April.  Our new comments address:

• Why CLF has renewed concerns about DOE’s control over its new environmental review contractors.  Based on our review of the Memorandum of Understanding between Northern Pass, DOE, and its new contractors, posted here (PDF), we explain that Northern Pass could still have an unfair and inappropriate influence on the content of the environmental impact statement and the schedule for completing it.
• What the Northeast Energy Link proposal means for the Northern Pass environmental review.  The recently announced Northeast Energy Link proposal, along with the Champlain Hudson Power Express project, makes it clearer than ever that we need a regional assessment of our energy needs.  These other two transmission projects also show that burying transmission lines in transportation rights-of-way is an abundantly reasonable alternative to overhead lines.
• How Northern Pass hasn’t clearly disclosed the source of power for the project.  We bring to DOE’s attention important information, obtained by CLF through its cross-examination of an executive of Northeast Utilities before Massachusetts regulators, that the source of Northern Pass’s power is likely to be new hydroelectric projects that Hydro-Québec is now in the process of designing and building.  CLF is especially troubled by the new information because the impacts of the project are much more significant if it causes the construction of new dams and the associated negative environmental impacts, including well-documented spikes in early greenhouse gas emissions from flooded land.  Northern Pass and its parent companies have consistently failed to acknowledge that these emissions undermine their claims about the reductions in emissions the project will supposedly provide.

A copy of our new comments is available here.  We also filed a Freedom of Information Act request with DOE, seeking to obtain a copy of the “Consulting Services Agreement” between Northern Pass and the environmental review contractor team.  The Memorandum of Understanding suggests that this separate contract includes important information on the budget and schedule for the environmental review, and the public deserves to know these details.

With the permitting process due to continue when Northern Pass announces a new northernmost route, CLF will be launching new ways to keep you informed about the latest Northern Pass news and the best ways for you to get involved and make your voice heard. Please stay tuned!

Beyond the discredited sales pitch that Northern Pass will lower electric rates in New Hampshire, the developers have repeatedly claimed that the power to be imported through the Northern Pass project will be “low-carbon,” “clean,” and “green,” with “no greenhouse gases,” and “no global warming.” The power will also, we’re told, “improve the quality of the air we breathe.” The developers have said, over and over, that the project “is expected to reduce regional carbon dioxide emissions by up to 5 million tons per year, the equivalent of removing from the road one million cars annually.” In fact, the study on which this claim is based – a report (PDF) commissioned by Northern Pass and authored by Boston-based energy consultant Charles River Associates – began with the assumption that hydro power is “zero-carbon.” Let me repeat that: the developers’ claim that the project will reduce carbon dioxide emissions by a net 5 million tons is based on their unexamined presupposition that the power to be delivered by the project has no carbon dioxide emissions at all.

There’s no other way to say it: this assumption is false.

You don’t have to take my word for it; read Hydro-Québec’s own research report (4.4 MB PDF) on the net greenhouse gas emissions of the Eastmain 1 Reservoir, flooded in 2005 (aerial shots here). In an Orwellian twist, the developers of Northern Pass have repeatedly cited this very same research.

The Hydro-Québec report found that net carbon emissions from Eastmain-1 were 500,000 tons in 2006 and 165,000 tons in 2009, and are projected to average approximately 158,000 tons per year on a long-term basis.  While certainly less than coal-fired power plants – PSNH’s Merrimack Station emitted more than 2.8 million tons of carbon dioxide in 2010 – 158,000 tons of net carbon emissions per year is far from ”zero-carbon” or even “low-carbon” power.  Based on our own survey of reservoir greenhouse gas research, we have some serious questions about the report, and there is reason to believe that it understates emissions over time and per unit of energy generated. But the report does confirm that Hydro-Québec’s reservoirs will continue to emit more greenhouse gases per year than the natural environment they flooded. These emissions are locked in for decades if not centuries – unlike a power plant that burns fuel, you cannot turn off a reservoir.

When compared with the power plants that Northern Pass’s power could displace, new hydroelectric projects in their early years of operation are no cleaner in terms of carbon emissions.  According to the report, ”it takes about five years for the accumulated CO2 eq. emissions to fall below the [natural gas combined cycle] value” (p.15). So, on a net and cumulative basis since its flooding in 2005, the Eastmain 1 Reservoir has had the same carbon dioxide-equivalent emissions as a modern natural gas power plant that has the same power output and began operating in 2005. 

The report also highlights what appears to be a clear difference between the net emissions of a newly impounded reservoir and the emissions of a reservoir that was impounded decades ago: a new reservoir emits more greenhouse gases, as the vegetation and organic material in the newly inundated area decompose.

This distinction is especially important when considering the contradictory stories we have heard about where Northern Pass will get its power. On the one hand, Northern Pass’s website claims (click on “Hydro-Québec” on this page) that “Hydro-Québec does not need to build any new generation to support this project.” On the other hand, it is clear that Québec is developing and planning vast new hydroelectric projects, many of which will require new inundation and reservoirs, as part of a concerted strategy to maintain and increase exports to New England and the northeast United States. See Erin’s blog post from yesterday for more on Vermont’s new long-term contract with Hydro-Québec. 

In fact, Charles River Associates’ fundamentally flawed estimate of carbon emissions reductions depends on the development of new hydro projects in Canada. And just ten days ago, in testimony to Massachusetts regulators, Northeast Utilities’ CFO David McHale stated under oath: “We already know for a fact that the utility Hydro-Quebec has initiated the construction of dams, and we’ve already entered into the record a discussion about the Eastmain Water Reservoir that will provide the water source. So this is not speculative. They’re building the dams and they will go into service; and that will be the primary source, if not the exclusive source, of energy that will flow over [the Northern Pass] line. . . . [T]hat is the full expectation.” What McHale was referring to is Hydro-Québec’s major new project in the vicinity of Eastmain-1 – the Rupert River project (project website here and explanatory animation here). Since 2009, this 918-MW project – now in the final stages of development – has newly flooded 346 square kilometers  - an area about the size of two Lake Winnipesaukees. That Northern Pass power will be coming from new projects means that Northern Pass will enable and contribute to the substantial carbon emissions associated with new reservoirs.  There has been no accounting of the potential emissions from the Rupert project and other future projects that Northern Pass may make possible, and how they would cut into the potential emissions reductions Northern Pass and Charles River Associates have claimed.

These inaccuracies and contradictions are being disseminated with hundreds of thousands of dollars in media buys, money which could have been invested in engaging in a collaborative process to rework the current proposal.  This situation makes CLF’s fight for a world-class, independent, and comprehensive permitting process all the more important.

CLF has been adamant that the Department of Energy must consider the environmental impacts – including greenhouse gas emissions – of the hydropower generation projects and any other power plants in Canada that will supply the Northern Pass project.  Given the developers’ recent announcement of new delays in their schedule, there’s still time for the Department of Energy to change course and answer our call for a regional, holistic analysis of the right approach to importing power from Canada, taking into account the truth about that power’s greenhouse gas emissions.
