The NH Department of Environmental Services recently released its long-awaited draft Great Bay Non-Point Source Nitrogen Study, providing a breakdown of the sources of nitrogen pollution in the estuary, and additional insights on how to improve and protect water quality.

According to the draft study, the Great Bay estuary receives, on average, a total load of 1,225 tons per year of nitrogen pollution.  Of that total load, 390 tons (32 percent) come from sewage treatment plants. The remainder – approximately 900 tons per year – comes from a variety of so-called “non-point” sources: sources of pollution that are less discrete and less concentrated than what many of us may think of as a pipe discharging pollution from a facility. The draft study looked at four major “non-point” inputs of nitrogen pollution – atmospheric deposition, chemical fertilizers, septic systems and animal waste.

The study found that atmospheric deposition accounts for roughly 280 tons of nitrogen pollution annually (23% of the nitrogen load to the estuary). While a large percent of this is from out-of-state sources, such as polluted air from the Midwest, the rest comes from New Hampshire.

We can all help, by taking actions that reduce air pollution – such as by driving less, carpooling, using public transportation, using less electricity, and purchasing power from sources other than PSNH, which continues to operate polluting coal-fired power plants like Portsmouth’s Schiller Station. CLF has joined the empowerNH campaign, which provides information about how you can switch away from PSNH’s dirty, expensive energy and purchase cheaper, cleaner power.

According to the study, chemical fertilizer is another source of nitrogen pollution, adding 30 tons of nitrogen per year, or 18% of the estuary’s total load. Lawns and agricultural areas each contribute about the same amount, while recreational fields, parks and golf courses are only responsible for a small fraction of the total. The message here is clear – agricultural operations need to implement best management practices, and we need to have smaller lawns and use less fertilizer. Learn how you can have a healthy lawn and protect the environment.

Did you also know that more than half of the nitrogen load to the Great Bay estuary comes from human waste?

Human waste from septic systems accounts for 240 tons per year of nitrogen pollution. Add that to the 390 tons per year from sewage treatment plants – the single largest source of nitrogen pollution (and a source that can be easily controlled through sewage treatment upgrades) – and human waste accounts for a whopping 630 tons per year, meaning over half of the total nitrogen load to the estuary comes from human waste.

Animal waste accounts for the remaining 110 tons per year of nitrogen pollution in the estuary, with livestock responsible for most of this total. The rest is from pet waste. While pet waste is not a big part of the problem, reducing the water quality impacts of our pets is something all pet owners can do. Learn about environmentally friendly ways to care for your pet.

According to the study, much of the nitrogen from these non-point sources reaches the estuary through stormwater runoff. This means that in addition to reducing pollution from sewage treatment plants, we have to tackle the difficult challenge of stormwater pollution. Looking forward, it will be essential for communities to adopt “green infrastructure” approaches that reduce runoff, and to promote more compact development patterns as opposed to land-consuming sprawl. Incredibly, as a result of sprawl, impervious surfaces (roads, parking lots and rooftops) in New Hampshire’s coastal watershed increased 120 percent since 1990!

The study also modeled nitrogen loads for individual subwatersheds and towns to identify “hot spots.” These results should be useful in prioritizing efforts to reduce non-point sources of nitrogen and will complement a study being completed by the UNH Water Resources Center to pinpoint many of these hot spots.

Did you find this information useful, interesting, or believe more work needs to be done? Then you can be involved. The Department of Environmental Services is accepting public comments on the draft report until August 16, 2013.

This past Friday, staff from the New Hampshire Public Utilities Commission and The Liberty Consulting Group issued the results of their investigation (PDF) into the impacts of PSNH’s failing business model and “ever higher costs” to consumers. The Union Leader and NHPR were quick to quote the report’s damning conclusion:

In summary, the situation looks to worsen, as continuing migration from PSNH’s default service by customers causes an upward rate trend. We find no supportable basis for optimism that future market conditions will reverse this unsustainable trend, especially in the near term. To the contrary, the PSNH fossil units face uncertainties that combine to create a risk of further, potentially substantial increases in costs.

This underlines the benefits of abandoning PSNH’s residential energy service, noting that “PSNH’s default service rate has exceeded [competitive supplier] rates since mid-2009.” As PSNH itself stated in a filing before the NH Supreme Court in May, PSNH energy service ratepayers “have the legal right and ability to avoid payment of PSNH’s default energy service rate entirely by buying their electricity from a competitive electric power supplier.” The PUC staff’s report serves as a call to action for New Hampshire consumers to save money, protect their finances, and improve the environment by buying energy from lower cost and more efficient energy suppliers.

PSNH’s only public response to the report thus far has been to cite the dispatch of their coal units during extreme temperature events this year as evidence that the plants are necessary “insurance” against natural gas price increases. The report itself contradicts this, however, noting that even at this year’s levels of natural gas price spike frequency and severity in New England (due to a cold winter and a late spring heat wave two weeks ago), natural gas price fluctuations “have not served to give the PSNH fossil units enough of a boost to overcome their negative value,” and that PSNH has not offered any data or analysis to rebut this finding. That is, even with the extreme peaks of electric demand felt in the past year requiring their use more often than in the past few years, PSNH’s fossil fuel fired power units still lose ratepayer money.

The report assesses the real financial impacts of PSNH’s past and possible future decisions to invest in their coal units rather than shut them down, and demonstrates that the ratepayer money lost if PSNH’s electricity generation is sold off will be lower than many might fear. The key points raised by the report include:

• Even in a best case scenario, PSNH’s already above-market rates will continue to climb. The investigation calculated PSNH’s energy service rates with a myriad of possible variables, including high natural gas prices and lower coal prices (the scenario that PSNH claims will validate its economic decisions) and a migration rate lower than PSNH reported this April. In all cases, the report found that PSNH’s default energy service rate would climb still higher than their current well above market 9.54 cents per kilowatt hour rate, to 10 or 11 cents per kilowatt hour.
• Customers continue to flee PSNH’s energy service. CLF has been reporting the steep increase in residential customers rejecting PSNH’s high energy service rates for a while now. We’ve also noted that most large commercial customers had migrated away from PSNH years ago. The combination of these two trends led to the report this May that migration across all customers reached half of PSNH’s total load as of the end of April.
• The full cost of the Scrubber Project has yet to be felt by ratepayers. PSNH has started recovering the cost of the ill-founded scrubber installation at Merrimack Station to the tune of 0.98 cents per kilowatt hour on a temporary basis. The report estimates that full recovery of the scrubber’s cost would nearly double that amount, to 1.8 cents per kilowatt hour added to ratepayers’ bills. This, of course, is a cost that competitive energy service providers don’t have to deal with.
• Looming environmental compliance projects as Scrubber redux? PSNH is currently waiting for its new final permit from EPA for cooling water withdrawal and discharge at Merrimack Station. The final permit is likely to require cooling water intake structures (like those constructed at Brayton Point Station in MA), at a price tag of $111 million or more, in addition to other protections for water quality and wildlife. Costs associated with new or impending air quality requirements would require additional compliance at significant cost, and these estimates don’t even take into account the risk posed by CLF’s ongoing Clean Air Act citizen suit.
• Potential ratepayer costs from divestment of PSNH’s electricity generation would be minimal. If PSNH’s generating assets are sold, New Hampshire state law allows PSNH to recover from ratepayers costs that are not covered by sale proceeds (“stranded costs”). The report roughly estimates that potential energy service rate increases to cover stranded costs would be no more than 0.9 cents per kilowatt hour and possibly much less, given the high value of PSNH’s hydro generation units.

The report ultimately recommends that the PUC initiate a proceeding to solicit formal feedback on the report and its conclusions. This proceeding would likely result in firmer value estimates for PSNH’s assets, interim steps that could be accomplished through the PUC’s existing authority, and more detailed recommendations for legislation.

As CLF and the Empower NH coalition have repeatedly noted, promoting and advancing competition in New Hampshire’s energy service markets yields only benefits for the state’s electricity ratepayers in the face of PSNH’s “ever higher costs” to ratepayers. While the PUC and the Legislature decide how to implement the recommendations of this report, ratepayers should continue to vote with their feet and leave PSNH’s energy service.

New Hampshire’s state flower, and my favorite sign of spring.

It’s another spring in New Hampshire, and the slow death of Public Service Company of New Hampshire’s (PSNH) coal-fired business model continues, as do PSNH’s efforts to hold back reality and hold on to its regulatory protection from competition. More and more PSNH customers are choosing cleaner, cheaper energy options, the company is again getting special treatment as it initiates a strange new program to lure those fleeing customers back, and its dirty and inefficient coal plants are once again sitting idle, with PSNH customers still paying for their upkeep.

Increasing Choices for PSNH Customers

PSNH (and shareholders of PSNH’s parent company, Northeast Utilities) must be wondering when the rate of residential customers abandoning PSNH’s energy service will slow. It certainly wasn’t during the first three months of 2013, when the number of households purchasing power from PSNH’s competitors topped 49,000. By comparison, that number was 2,704 at the end of March 2012.

The number of small businesses migrating away from PSNH has steadily increased, from 11,194 in March 2012 to 16,919 this March. Of course, PSNH’s medium and large commercial customers have been taking advantage of competitive suppliers since long before it was a practical option for residents, and they move back and forth from PSNH and the competitors much more frequently; in any given month, between 75% and 90%+ of medium and large businesses purchase their power from PSNH’s competitors.

Source: PSNH data

We last checked in on PSNH’s accelerating death spiral in January, highlighting the historically low use of its coal plants to produce power and the flight of customers away from PSNH’s ballooning rates. The utility’s ancient, filthy coal plants are sitting idle for large stretches of time during the year, at substantial cost to ratepayers, because PSNH is able to recover its costs and a guaranteed profit from its customers even when it isn’t economic to put the plants online. Despite a winter when the spot market price of natural gas was very volatile, PSNH’s coal plants provided no economic relief to its customers, as its energy rates remained almost 40% higher than those offered by other New Hampshire utilities and energy suppliers.

In response to the huge disadvantage posed by PSNH’s coal plants, the competitive atmosphere has continued to flourish in New Hampshire’s energy market in 2013. We’ve previously highlighted the residential energy services offered by companies like ENH Power and North American Power, and still more companies are hurrying to take advantage of PSNH’s above-market rates by siphoning off customers.  As the Union Leader recently reported, four new competitive suppliers have applied for licensing with the NH Public Utilities Commission already this year.

The “Alternative Default Rate”

Looking to secure a special deal to protect itself from its new competitors, PSNH applied for and received [PDF] regulator approval to pilot an “alternative default rate” to lure back customers who had switched to other suppliers. The alternative rate will only be available to large commercial customers at first, with small businesses and residential customers to be added to the program within nine months.

After the increased public awareness of competitive electricity supply in NH around the end of 2012 rate hike, the press and public were quick to take note of this plan, and customers who stayed with PSNH through the January rate hike feel doubly burned.

Saving by Switching

After PSNH’s astronomical rate hike in January, the energy rates offered competitive suppliers like ENH Power and North American Power should be even more attractive to PSNH customers who were previously cautious about making the switch. And switching online is easy, free, and safe: it takes a matter of minutes if you have a copy of your latest PSNH bill handy.

As spring turns to summer, and PSNH’s troubles grow, the ongoing challenge remains: to ensure that clean energy competition continues to flourish in the Granite State and that PSNH does not secure a legislative or regulatory bailout that subsidizes its dying business model. Although PSNH doesn’t seem willing to change its terrible economic decision to keep operating its coal plants, New Hampshire residents and businesses are taking matters into their own hands and deciding to do something about it.

How are PSNH’s coal plants like Mark Sanchez? (photo credit: flickr/TexKap)

Earlier this week, the Concord Monitor published a must-read editorial addressing PSNH’s future. Much like an earlier widely-printed op-ed on the subject, the editorial correctly describes the PSNH death spiral of escalating costs, fleeing customers, and dirty inefficient power plants kept alive by massive ratepayer subsidies.

The editorial also points out one key reason why PSNH’s argument that its plants are an insurance policy against high natural gas prices is increasingly off the mark: it ignores the damage that those plants do to the climate and to the environment. In 2012, despite not operating for much of the year, PSNH’s plants were nonetheless collectively the single largest source of greenhouse gas emissions in New Hampshire.

As time goes on, PSNH’s “insurance policy” argument only gets more specious. Relying on inflexible power plants that take many hours to start up and shut down is diametrically at odds with the dynamic and advanced electric grid that will help New England move toward a clean energy future and address concerns around the region’s increasing use of natural gas. We know what we need to do: the region needs to reduce energy demand through cost-effective energy efficiency investments, to deploy clean renewable technologies like wind that displace fossil fuel use, and to optimize the rules of the wholesale electric market to ensure smooth operation of the grid. Indeed, regional grid operator ISO New England’s recent market design efforts will almost certainly make poor-performing, inflexible power plants like PSNH’s less competitive, not more.

Propping up outdated physical assets – with high fixed maintenance costs – in the hopes that they will someday become competitive again is not “insurance.” It’s the kind of backward thinking that no competent manager or economist would endorse.

As a matter of policy, PSNH’s strategy enacts the classic economic mistake of “throwing good money after bad” by placing too much emphasis on “sunk costs,” an unfortunately common problem that James Surowiecki recently discussed in The New Yorker in describing the irrationality of sports teams’ commitments to ineffective players, like the Jets’ Mark Sanchez, after years of poor performance and bloated salaries.

At least sports teams suffer the consequences of their choices – they lose. With guaranteed profit and regulator-approved rates to recover its costs, PSNH and its parent Northeast Utilities have continued to win, even after a decade or more of terrible investment decisions. Unless of course PSNH can be made to pay for the mess it has created.

The key paragraph of the Concord Monitor’s editorial argues precisely this same point:

[L]awmakers must ensure that the lion’s share of the loss is incurred by investors in PSNH’s parent company, Northeast Utilities, not by New Hampshire ratepayers. That includes the huge cost of the mercury scrubber. It was investors, after all, who gambled that it made sense to spend hundreds of millions of dollars to keep an old coal plant running. They could have said no. So it’s investors who should lose if that gamble doesn’t pay off.

As PSNH looks for opportunities to spread its costs to the New Hampshire businesses and households that have escaped PSNH’s high rates, this is timely advice for New Hampshire policymakers. They should heed it.

The massive drag on New Hampshire’s economy caused by PSNH’s continued operation of the uneconomic and obsolete Merrimack Station and Schiller Station coal-fired units—extracting hundreds of millions per year in above market costs for its shareholders—is spiraling out of control, and several recent developments at the NH Public Utilities Commission raise troubling questions about what the agency empowered to protect ratepayers is doing about PSNH’s problems.

While competition among energy suppliers in New England is fostering efficiency, benefitting the environment and saving ratepayers money, PSNH’s energy service business, for which it collects its cost of service and a handsome profit, is increasingly looking like a dinosaur ready for extinction. Thousands of NH ratepayers are taking advantage of lower cost, more efficient electricity suppliers, but those remaining with PSNH are being dragged down into its death spiral.

One recent indicator is PSNH’s skyrocketing energy service rate. In early December, PSNH requested a 34% energy service rate increase (to 9.54 cents/kwh, equating to hundreds of dollars extra per household per year) beginning in 2013. At the end of December, the PUC approved the rate increase. CLF is challenging that increase at the PUC on the grounds that, even aside from the fact that it entirely consists of above market costs, NH law prevents the PUC from approving a utility’s requested rate increases when the utility has not submitted required planning documents demonstrating that it has a sound plan for serving its customers at the lowest cost. PSNH failed to submit long term least cost planning documents due last September; until they do so, the PUC is not authorized to approve their rate increases.

Fundamentally, the job of a utility commission dealing with a regulated utility like PSNH is to ensure that prices mimic the results of market competition while ensuring the best service for ratepayers. Thus far, the PUC has shielded PSNH from the consequences of its poor decisions, lack of meaningful planning, and insistence on retaining antiquated power plants that sit idly due to their high costs. It also is once again delaying the release of economic and environmental information that PSNH used when deciding to build the $422 million scrubber project at Merrimack Station. And days ago the PUC approved PSNH’s 2010 plan for its energy supply resources – a plan that utterly ignored lower natural gas market forecasts and impending environmental regulations when planning its future operations.  CLF is acting to protect ratepayers from PSNH’s dying business model; the extent to which the PUC is doing so is less than clear.

The PUC is engaged in dockets investigating both the costs of the scrubber project and PSNH’s increasing energy service costs. It remains to be seen whether these investigations will have any impact on the expensive mess PSNH has yoked to NH ratepayers, and whether PSNH will continue even farther down the path of  eroding New Hampshire’s advantage as a low cost state to grow a business and a family.

The data don’t lie. In line with the trends we’ve been warning about for years, PSNH’s coal-fired business model is in free fall:

Residential and small business customers continue to flee PSNH’s dirty, increasingly expensive energy service.

Source: NHPUC data

• Over the past year the number of residential energy customers in New Hampshire who purchased energy service from a supplier that is not PSNH jumped to around 30,000 households in December of 2012 (compared to around 2,000 households in December of 2011).
• That figure doesn’t include the veritable flood of customers who abandoned PSNH’s energy service at the end of 2012 when word got out about PSNH’s 34% rate increase (ENH reported signing up 1,700 customers on December 31 alone for service starting January 1). The stampede of residential and small business customers away from PSNH’s energy service shows no signs of slowing down.

PSNH’s coal plants are becoming even less competitive and will operate even less in 2013 than in 2012.

Source: ISO-NE, EPA, and PSNH data

• We noted before that PSNH’s coal unit capacity factors have taken a nosedive over the past five years, and they are projected to keep falling on an annual basis in 2013 (see chart below).
• A power plant’s capacity factor reflects the amount of power the plant generated compared to the amount of power it could have generated if used to its full potential; when that number is low, it means it was a better economic choice for the plant’s owner to keep the plant idle most of the time. While other coal plants throughout New England are also running at low capacity, PSNH is the only utility in the region that can force ratepayers to bear its fixed costs plus a hefty guaranteed profit, even when its plants don’t generate power.

The Bottom Line:

Even as many customers are taking advantage of cleaner, cheaper alternatives, PSNH’s dirty and costly power plants are a heavy – and growing – burden for the majority of New Hampshire ratepayers and for New Hampshire’s economy. In a future post, I’ll discuss how the state agency tasked with protecting ratepayers from unreasonable rates is handling PSNH’s implosion (spoiler: not well) and what CLF is doing about it (another spoiler: fighting to protect New Hampshire ratepayers and the environment).

Today, the New Hampshire Public Utilities Commission takes up PSNH’s request to charge its customers 9.54 cents per kilowatt hour for electric energy service in 2013. In a op-ed published this week, long-time CLF friends Ken Colburn and Rick Russman explain why New Hampshire’s crisis of escalating PSNH rates – and how New Hampshire policymakers resolve it – may be the defining economic issue for New Hampshire’s new class of leaders next year.

With PSNH’s rates to be by far the highest in the state and almost three cents higher than those of its sister utility NSTAR in Massachusetts, New Hampshire is dealing with an untenable situation: small businesses and residents are subsidizing PSNH’s above-market costs to operate and maintain dirty, inefficient, and uneconomic coal plants, to the tune of $128 million.* The average residential customer will pay $212 extra in 2013 for the dirtiest energy in the region.

To put $128 million in perspective, in 2011 New Hampshire invested less than a seventh of that amount, a mere $17.6 million, in electric energy efficiency programs – an energy solution that is lowering rates, reducing pollution, avoiding expensive new transmission projects, and creating jobs.

New Hampshire energy users are in effect giving this money away to keep alive New Hampshire’s biggest sources of toxic and greenhouse gas pollution (even though PSNH projects they will only operate at around 25% of their capacity in 2013) and to pay dividends to PSNH’s owner, New England mega-utility Northeast Utilities. And the situation will only get worse with time as PSNH customers join the thousands who have already picked an alternative energy supplier, leaving a shrinking base of customers to bear the heavy costs of PSNH’s coal fleet. (If you’re still a PSNH customer, you should definitely make the switch before the new year begins and PSNH’s new rates kick in.)

The blame for this economic and environmental travesty lies squarely with PSNH’s self-serving failure to plan for the future.

Yet PSNH is already trying to make the case that it needs a “fix” from the New Hampshire legislature to protect its coal plants, its 10% profit margin guarantee, and its protection from cleaner, cheaper competition. What’s even more bizarre – and indicative of its refusal to approach these issues honestly – is that PSNH is pinning its skyrocketing rates on the very factors that have reduced electric rates for everyone else in New England – namely, investments in energy efficiency and environmental protection and the increasing use of natural gas and competitive renewable energy sources. PSNH’s foolhardy but lucrative investments in its outdated power plants – for which it fought tooth and nail over the last decade – are the culprit, not environmental requirements that apply to all power plants in New Hampshire and across the region.

Please take a moment to read the op-ed and share widely with friends, neighbors, and especially your new representatives in Concord. For the good of the state’s economic and environmental health, they need to hear from you!

*  The math: PSNH customers will pay a 2.85 cent “premium” for every kilowatt hour over and above PSNH affiliate NSTAR’s market-based rates, and PSNH is projecting that it will sell more than 4 billion kilowatt hours of power to its remaining customers in 2013. The average household in New Hampshire uses 7,428 kilowatt hours per year.

PSNH's Merrimack Station

For the past 25 years, Toxics Action Center has been “awarding” New England’s worst polluters with the dubious Dirty Dozen award. This year’s winners were no surprise: PSNH, New Hampshire’s largest electric utility, was on the list once again.

In this year’s annual spotlight on twelve of New England’s worst polluters, PSNH’s largely coal-firing Merrimack Station and Schiller Station power plants earned the award for the millions of pounds of toxic air pollution and greenhouse gases released by the plants. The Dirty Dozen awards are getting lots of press coverage around New Hampshire, and highlight the massive problems PSNH’s coal plants cause New Hampshire residents.

There is good news. Three of New England’s eight coal plants have closed in the past three years, and the rest (including Merrimack and Schiller) should be well on their way thanks to the massive economic inefficiencies of burning coal in the age of cheap natural gas. While these giant, ancient plants were built to run all day, all year round, the reduced demand for coal energy means that plants like Merrimack and Schiller are being used at historically low rates.

While the current cost of energy production at coal plants is staggering, nothing represents the exorbitant costs of coal better than Merrimack Station’s $422 million scrubber project. PSNH is already recovering the cost of that “investment” from its customers with a temporary rate increase, and has requested an even higher permanent rate increase to recover scrubber costs. Installing massively expensive pollution controls on an obsolete coal-fired power plant was recently shown to be a valueless endeavor when the investment firm UBS valued Dominion Energy’s Brayton Point coal plant (currently for sale) as a worthless asset, due to its poor prospects in the New England wholesale electricity market. Dominion has essentially written off its almost $1 billion pollution control investment at Brayton Point, which has little utility to a plant that does not operate due to its high cost to produce electricity in comparison to cleaner sources.  Merrimack Station’s scrubber investment is faring even worse in the market, because the plant is older and less efficient than Brayton Point.  In this regard, Dominion’s write down at Brayton Point foreshadows the future for Merrimack’s “investment.”

As we documented earlier this month, PSNH’s residential and small business energy service customers are abandoning the utility in favor of its competitors at a breakneck pace, following the lead of its medium and large commercial customers and creating an economic “death spiral” as costs climb and customers disappear. And since PSNH is guaranteed a profit by NH law for maintaining and operating its coal plants, the repercussions of the “death spiral” are felt by residential customers, rather than the company’s shareholders.

The residential customers who have not switched to a different energy service provider are projected to subsidize PSNH’s dirty power plants by an estimated $70 million above market rates in 2013. The above-market residential rate payments are then turned into dividends for the shareholders of Northeast Utilities, PSNH’s Connecticut-based parent company.

Northeast Utilities’ dividends are increasing steadily on the backs of New Hampshire ratepayers, and Merrimack and Schiller continue to produce pollution more efficiently than they generate electricity. How long will PSNH be allowed to fleece New Hampshire’s citizens?

Co-written with N. Jonathan Peress

It’s not news that New Hampshire’s ratepayers are paying too much money to support PSNH’s ancient, massively inefficient, and heavily polluting coal-fired power plants. CLF has repeatedly called out PSNH’s calamitous insistence on continuing to operate coal-fired units at Merrimack Station in Bow and Schiller Station in Portsmouth and the resulting exorbitant electric rates that PSNH customers pay.

It’s still possible to be shocked, however, by the magnitude of PSNH’s growing problems and the environmental and economic harm that PSNH’s collapse is causing in New Hampshire. And the situation is worsening: new data are confirming the futility and waste of operating coal plants, and New Hampshire ratepayers are, in what is now a full-scale stampede, abandoning PSNH to meet their electric needs with cleaner, cheaper energy from competitors.

Here is an update on PSNH’s so-called “death spiral”:

Unprecedented Idling of Power Plants

A power plant’s “capacity factor” is a ratio between the amount of electricity the plant actually produced over a given period and the amount that it would have produced had it been running at full capacity during that time. Because coal plants – like nuclear plants – take some time to ramp up and take offline, they are built to operate with a very high capacity factor, on a 24-7 basis. In 2007, PSNH operated Merrimack Station’s coal boilers at 91% capacity and Schiller Station’s coal boilers at 84%.

The new reality for PSNH: these numbers have fallen precipitously since then; over the first nine months of 2012, Merrimack’s coal units had a capacity factor of 31%, and Schiller’s coal units 9.7%.

* 2012 data through September (source: EPA and ISO-NE data)

With dirty coal being trounced in the marketplace by cheaper power sources, especially natural gas, it is a disproportionately expensive undertaking to operate a coal unit – and a veritable folly at these levels of output.

Energy Service Rate Hike in 2013

The problem for PSNH’s customers is that even though the writing is on the wall for coal power plants around the country and here in New England, PSNH is still guaranteed a ratepayer-funded profit for owning Merrimack and Schiller, which is handed over to PSNH whether or not the plants produce power. Add it all together – PSNH’s operating costs for Merrimack, Schiller, and its other power plants, PSNH’s guaranteed profit, and the cost of the “replacement” power PSNH buys from the regional market to provide electricity to its customers while its plants sit idle – and PSNH customers are paying a huge and increasing premium over rates in the competitive market.

While there are many separate charges on an electricity bill, the “energy service” rate reflects the costs of generating the electricity. At the end of September, PSNH filed a projection (PDF) with the New Hampshire Public Utilities Commission warning of a residential energy service rate increase to take effect on January 1, 2013. The utility requested a 26% increase in the amount customers pay for electricity supplied by PSNH, bringing the overall default energy service rate to 8.97 cents per kilowatt hour. PSNH has also separately requested a permanent rate increase to recover the costs of the $422 million mercury scrubber that, if passed, would bring the default energy service rate to 9.27 cents per kilowatt hour.

By contrast, just over the border in Massachusetts, PSNH affiliate NStar’s residential customers will be paying a mere 6.69 cents per kilowatt hour for power that NStar almost wholly buys from the regional market. NStar’s rates are, like virtually all New England utilities other than PSNH, reflective of the historically low electricity prices available in that market, which have steadily fallen since 2008.

What this means is that, come January, the average PSNH-served New Hampshire home will be subsidizing PSNH and its power plants to the tune of $169 per year, or more than $190 per year with the addition of the extra charge for the scrubber.

Residential and Small Business Customers Increasingly Abandoning PSNH

As CLF documented recently, PSNH’s increasing rates represent an enormous market opportunity for competitive energy suppliers in New Hampshire.

They are seizing it. September 2012 data show 17,507 residential PSNH customers (about 5%) purchasing power from non-PSNH suppliers, an increase of more than 6,000 customers over the month before and a whopping 16,000 more than September of 2011. The number of small businesses fleeing PSNH’s electricity supply has grown at a steady rate: 14,617 purchased power from non-PSNH suppliers in September 2012, compared to 9,351 in September 2011.

(source: PSNH filings with N.H. Public Utilities Commmission)

Meanwhile, the most recent data show that there are now virtually no large or medium-sized businesses that buy power from PSNH.

While retail choice in suppliers for New Hampshire’s residential and small business customers was slow in coming, the available options have expanded considerably in the past year. Resident Power, Electricity NH, and Glacial Energy all quote lower rates than PSNH, and they are increasingly offering additional choices of electricity supply from coal-free, renewable, and sustainable sources at fixed rates lower than PSNH. We can expect an even faster exodus to these suppliers and new ones like them after PSNH’s rate increase in January.

Despite the rapidly increasing number of customers choosing alternative electricity suppliers, the vast majority of New Hampshire’s residential customers still purchase their electricity from PSNH. Many customers are unable or too busy to research comparative rates and make the change. And energy supply choice alone will neither affect the astounding subsidies that PSNH is getting to prop up its failing business nor force PSNH to make the economically rational decision to retire its dirty, outdated coal plants.

We need to correct this massive public policy failure and bring to an end the severe economic, environmental, and public health damage that PSNH’s ancient coal plants are causing in the Granite State. There is now reason to believe that we are turning a corner. Maggie Hassan, New Hampshire’s new governor-elect, has been outspoken about the importance of reducing pollution from electricity generation, especially from PSNH’s coal fleet. CLF is ready to work with the new administration and Legislature to develop a comprehensive climate and energy plan that transitions the state out of the grip of PSNH’s coal-fired business model and moves New Hampshire toward a cleaner and affordable energy future.
