What would Northern Pass mean for our climate?

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.

Northern Pass’s phantom “benefits”

I appeared on NHPR’s The Exchange with Laura Knoy this morning, and the topic was the potential energy and economic impacts of the Northern Pass project. The show provided a good opportunity to explain why the project is inspiring so much opposition, why CLF has been skeptical of the current proposal, and how Canadian hydropower could play a role in the New England electric system if pursued appropriately. There was also a segment on the project’s potential impact on property values. You can catch the replay here if you’re interested.

Joining me on the show was Julia Frayer, an economist hired by the Public Service Company of New Hampshire (PSNH) to tout the energy and economic benefits of the project. Recently, she penned a widely-reprinted op-ed and provided testimony to the New Hampshire legislature, suggesting the project will be a boon to consumers and the reliability of the electric system.

Unfortunately, and as I made an effort to point out on the show, the arguments for the current proposal are pleasant talking points without much to back them up. All the cited benefits are speculative, rather than firm commitments, and are not forthrightly presented alongside the proposal’s potential costs. As any student of economics can attest, an intelligent discussion about the economics of a project requires that we at least try to describe and compare the costs and benefits.  We know that the project may have significant negative impacts, ranging from the environmental impacts of generating the power in Canada to the potential effects of major new transmission lines on New Hampshire’s tourism and recreation industries. PSNH and the project developer, Northern Pass Transmission, LLC, have stubbornly failed to acknowledge these impacts, and there is no evidence they were taken seriously in the planning of the current proposal.

One point worth highlighting – the current plan calls for all of the supposed clean energy benefits and electric rate reductions to be delivered through the wholesale market, where Hydro-Quebec intends to sell the power delivered by the project.  But these benefits would mostly bypass the very residential ratepayers in New Hampshire who pay PSNH for electricity – because PSNH acquires very little power from the wholesale market. Instead, as customers of PSNH’s retail power, PSNH residential customers have been left to shoulder the uneconomic costs of PSNH operating several coal-fired generating units – and to pay the highest electric rates in New Hampshire as a result. Northern Pass does nothing to change this situation.  Many commercial ratepayers in PSNH territory have “migrated” in increasing numbers to other utilities that – unlike PSNH – do buy substantial power from the wholesale market to supply their customers. Residential ratepayers don’t have this choice – which means they’re saddled with PSNH’s higher costs, as PSNH loses more and more of its commercial rate base.  Again, Northern Pass does nothing to change this situation.  On closer inspection, the claimed benefits for New Hampshire consumers look more like phantom benefits than anything real.

The proposal promises to send huge profits to Hydro-Quebec, as it bids power into the wholesale market (easily paying back its investment in the transmission lines), and to provide a revenue stream of transmission payments to Northeast Utilities, PSNH’s parent company. But this structure makes very little sense because it means New Hampshire residents will continue to bear the burden of high cost power and dirty air from PSNH’s coal plants and will also face the environmental and economic impacts of a massive transmission project, while the power would only displace relatively less-polluting natural gas generation and may undermine the development of local renewable energy projects in the state. If it does indeed lower costs on the New England market, the effect will be to increase costs for PSNH’s residential customers as more large customers migrate to the competitive market and fewer customers are left to pay the costs of PSNH’s expensive coal plants.

The current proposal is coming into focus as a bad energy and economic deal for New Hampshire, and regionally the benefits seem less than impressive – especially because the emissions reductions made possible could be so much greater if there was a firm commitment to pair the new imports with the retirement of coal-fired units. As the project continues to wind its way through the federal and state permitting process, CLF will keep pushing for the project to make sense for New Hampshire and for the energy future of the region as a whole.

“Plan Nord” and Northern Pass: New England needs its own plan

As noted in numerous media reports (for example, here and here), the Province of Québec has formally announced its “Plan Nord,” a 25 year, $80 billion plan to develop Québec’s northern region (official “nutshell” here).  Plan Nord reflects major new public investments in mining operations, hydroelectric and wind energy facilities, forestry, and transportation and communications infrastructure.

The scale of Plan Nord is hard to overstate; Premier Jean Charest is proudly proclaiming that Plan Nord is the “project of a generation,” “a sweeping, human adventure,” and “unique both in its scope and its approach.”  The plan adds that “the scope of the Plan Nord will make it in the coming decades what the development of La Manicouagan and James Bay were to the 1960s and 1970s.”  The land area covered by the plan is about twice the size of Texas.

The formal public launch of Plan Nord is an opportunity to think about what Québec’s plans may mean for New England and our regional energy future. A fundamental part of Plan Nord is developing the region’s energy resources, including new hydroelectric generating capacity totaling 3,000 megawatts.  (This amount of power is equivalent to five Vermont Yankees.) While important to the plan’s projections of provincial energy needs, these facilities are also integral to Québec utility Hydro-Québec’s strategy to step up exports of electric power to the northeastern United States, including New England.  The plan itself notes Vermont’s recent renewal of a long-term agreement to import 225 megawatts of power from Hydro-Québec as a key early success.

Although Québec has marketed Plan Nord as at the vanguard of “sustainable development,” any plan this massive and costly should inspire a fair amount of skepticism, especially when its scale is compared to the breathtaking ecological manipulations of Québec’s recent history. Indeed, the plan’s economic focus on new investments in mining suggests less than a total commitment to sustainability. On the other hand, as our colleagues at the Pew Environment Group’s International Boreal Conservation Campaign noted yesterday, the plan commits to protection of 50% of Québec’s northern land area for environmental protection and safeguarding biodiversity. It remains to be seen if this commitment is meaningful; if it is, it would be a historic and farsighted move.

CLF is deeply concerned about what this plan – including its focus on resource extraction and exploitation - means for Québec, New England, and indeed the global environment.  Hydroelectric developments on the scale contemplated by Plan Nord involve inundation of vast land areas, which in turn results in the destruction of wide swathes of Canada’s boreal forest – one of the world’s largest intact carbon sinks - as well as methane and other greenhouse gas emissions from decomposing vegetation and releases of heavy metals from flooded soils. Hydropower reservoirs in Québec already cover an area greater than the size of New Hampshire, and further inundation will be required for Plan Nord projects.   These projects have dramatic impacts on indigenous people and their way of life; at least some indigenous groups appear deeply dissatisfied with the public process that led to the Plan Nord.

With Plan Nord moving forward, the time is now for the U.S. Department of Energy to answer CLF’s call for a regional, comprehensive analysis of the nature and extent of the need for energy imports from Québec.  Québec clearly has a plan for its future, and – laudable environmental “commitments” aside – that plan is all about enriching Québec; New England and the northeastern U.S. need a coherent plan of our own that reflects our energy policies and environmental values.
