Update: PSNH Death Spiral Continues

Update: PSNH Death Spiral Continues

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.

A precipitous incline.

  • 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.

A precipitous decline.

  • 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).

Before you go… CLF is working every day to create real, systemic change for New England’s environment. And we can’t solve these big problems without people like you. Will you be a part of this movement by considering a contribution today? If everyone reading our blog gave just $10, we’d have enough money to fund our legal teams for the next year.
