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.

• 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.

• 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).

Coal-fired power is dying, not only across the nation, but across New England as well.  The region’s coal-fired power plant fleet has started to succumb to the costs of operating a coal-fired dinosaur in the age of energy efficiency, growing renewable electricity generation, and–for now–low natural gas prices.

Predominantly coal-fired Brayton Point Station in Somerset, Massachusetts, is the state’s largest single source of carbon emissions (producing over 6 million tons in 2010). Another harmful pollutant emitted by Brayton Point is particulate matter, which is measured daily by monitors that continuously check the opacity of the soot coming out of the plant’s smokestack. Brayton has been violating their limits for emitting that soot, and failing to monitor their emissions of several other harmful pollutants. Yesterday, CLF filed a notice of intent to sue Brayton’s current owners, Dominion Resources, for those violations. CLF’s upcoming lawsuit is just the latest in a growing list of bad news for Dominion and Brayton Point.

As New England’s other coal plants started to close or teeter on the edge of closure, Brayton Point Station was expected to be the last coal plant standing in the region. It is New England’s largest coal-fired power plant, and in the past decade its current owners, Dominion Resources, sank over $1 billion in pollution control upgrades into the behemoth. While Brayton Point does not have the kind of legal protection from market realities that PSNH exploits to prop up its dirty old coal generation in New Hampshire, many had assumed that Brayton Point was well-positioned to survive in the changing power generation landscape.

But the relentless pressure of low natural gas prices and the costs of starting up and operating an enormous coal-fired power plant have begun to affect every corner of the coal generation market in New England, and Brayton Point has not been spared. The plant’s “capacity factor,” which reflects the amount of power the plant generated compared to the amount of power it could have generated if used to its full potential, has taken a nosedive over the past three years. A plummeting capacity factor means that it is a better economic choice for a plant’s owners to keep it idle most of the time than to operate.

Dominion Resources, clearly, has seen the writing on the wall for coal in New England. After signing a binding agreement to cease coal operations at Salem Harbor Station as a result of CLF’s lawsuit against that plant, Dominion sold the Salem plant earlier this year. Following closely on the heels of the Salem sale, the company put Brayton Point on the market in September. While Dominion is marketing Brayton as a modern coal-fired power plant due to its recent billion-dollar pollution control investments, UBS recently assessed [PDF] the value of those investments (and the plant itself) at zero.

Brayton Point’s plummeting capacity factor and bleak sale prospects reflect both the current power of low natural gas prices and the weakness of these old, out-dated coal plants.  That trend will continue as the New England energy market continues to move forward with better integration of efficiency, conservation and renewable generation. Dark clouds are rising over Brayton Point. In the meantime, CLF and our partners will work diligently to hold the Brayton Point power plant accountable for producing its own dark clouds of pollution in violation of the law.

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?
