Experts Weigh In: Maine Doesn’t Need New Gas Pipelines

Jul 17, 2015 by  | Bio |  Leave a Comment

This week consultants hired by the Maine Public Utilities Commission (PUC) concluded that Maine should not enter into contracts to purchase gas pipeline capacity because the costs of doing so would outweigh the benefits to Mainers.

In many ways, this was a foregone conclusion – one that CLF predicted nearly a year ago and that the PUC itself (unofficially) reached before soliciting proposals from pipeline companies and spending taxpayer dollars on a lengthy consultant’s report. It’s a cautionary tale not just for Maine but for all of New England as the region weighs its energy future – and decides whether it will overinvest in natural gas or blaze a trail based on cleaner, renewable resources.

This process all started back in March 2014. After a cold winter sparked region-wide fears of an imminent shortage of natural gas to power our homes and businesses, Maine’s PUC was tasked with determining whether the state should contract for additional gas capacity under the Maine Energy Cost Reduction Act (MECRA). The PUC approached this work in two phases: first, soliciting and examining evidence and testimony from a variety of interested parties, including CLF, as to the need and economics of gas pipeline capacity procurement. And, second, if the economics made sense, to request proposals from pipeline companies.

CLF testified before the PUC as it gathered the evidence and data it would need to make their determination. We reasoned that Maine should not enter into new contracts with pipeline companies – both because the legal basis for them was suspect (the investment in these new projects would have been paid for by ratepayers, which is unprecedented and risky) and because the costs – to our wallets and our climate – would ultimately outweigh the benefits to consumers.

PUC staff agreed with the economic argument in their own preliminary report, but the Commission nonetheless went ahead and accepted supply proposals from pipeline companies. As required by MECRA, the PUC hired an independent consultant, London Economics International (LEI), to examine these proposals. The consultant’s detailed report compared scenarios in which the state didn’t contract for additional pipeline and ones in which it did (based on the actual proposals the state had received).

LEI’s analysis reinforces both CLF’s testimony and comments and the PUC’s own staff report issued during the first phase of this proceeding: The costs of any contract for Maine to buy natural gas pipeline capacity trumps the benefits. In fact, LEI concluded that, even without Maine entering into a gas contract, gas prices should drop by 25% for Maine customers over the next few years due to already planned, market-based gas capacity expansions. The group also found that electricity prices should drop by 15% due to these lowering gas prices.

The LEI report rightly calls into question whether the PUC should have accepted proposals from gas companies in the first place – a process that has been costly to all participants, expended valuable resources of the PUC, and resulted in no different a conclusion than the PUC’s own staff analysis.

Maine law requires that, for any contracts like these proposed expansions, the benefits must outweigh the costs. The conclusions drawn by the PUC’s expert consultant in their report should prevent Maine from entering into such a contract any time soon.

Ultimately, there’s a larger lesson here – one for every state in the region considering its electricity future. Over this year-long process, the PUC spent hundreds of thousands of (tax-payer) dollars on experts and an intense, litigation-like process, only for their experts to conclude what was readily apparent at the outset – that subsidizing the gas industry on the backs of ratepayers is a bad idea, both economically and for the environment.

Those gas shortage fears that sparked this whole process in the first place ended up being completely unfounded over this past winter. Since then the economics of the energy markets have started to shift, with wholesale electric prices declining by 50% over the past year alone. Meanwhile, energy efficiency is decreasing the need for energy resources, fuel-free renewables are supplanting polluting power plants, and liquefied natural gas has become cost-competitive and available at times of peak need. With at least two new small-scale pipeline projects already set to come on-line and reduce energy costs even more over the next two years, now is the time for the New England states to invest in the stability of the cleanest energy future we can create – one that weans us off of natural gas within the next 35 years.

How Climate Change Could Affect Your Lobster Roll

Jul 6, 2015 by  | Bio |  Leave a Comment

Did you think we could finally put this year’s harsh winter behind us? Think again. The summer season has officially started, but it seems our lobster roll – New England’s famed summer seafood – is paying the price for the snowy winter…or at least we are paying the price for the lobster roll.

Lobsters are available in New England year round, but any New Englander will tell you that the true lobster season kicks-off in the summertime. This is when the sweeter, juicier soft shell lobsters, often known as “shedders,” undergo molting, a growth process during which the crustaceans shed their old, too-small shells and grow new, larger ones. After the molting process is complete, the lobsters then migrate closer inshore where they are readily available for lobstermen to haul up in their traps.

So far this season there have been numerous news stories on the increasing price of lobster. On average, lobster per pound prices are already $1 to $2 more expensive than last year’s, a trend that University of Maine researchers have attributed to lower ocean temperatures due to the past winter.

Ocean water temperature heavily influences the timing and frequency of the molting process, which in turn influences when lobsters are ready for harvest. Adult lobsters living in colder waters will typically only molt once a year and are known to have later molting periods compared to those in warmer waters. Since the harsh winter caused a drop in ocean temperatures, the lobster molting season in New England has been delayed, at least compared to recent years. This has resulted in a lower supply of lobsters and a slower, more expensive start to the summer lobster season.

As Dr. Bob Steneck from the University of Maine told Business Insider, this summer “will be a one-molt season, based on temperatures,” and that molt will likely not occur until July or August. Unfortunately, until that occurs, we can expect to pay a little more for our lobster dinners.

Don’t let the cooler water temperatures fool you, though; if anything, this summer is a glimpse into the past. The start of this year is contrary to recent trends we are seeing in the lobster industry – lucky for our wallets, not so lucky for the lobsters. Lobsters are a cold-water species that will continually face the impacts of climate change such as warming ocean temperatures and ocean acidification on a daily basis.

Climate change is the reason why we saw record high lobster landings and low prices in 2012 and 2013. Warming ocean temperatures triggered an early molting and migration season for lobsters, leading to a high supply early on in the summer. Also, since the molting occurred so early, we experienced a two-molt season, which is atypical for New England waters and leads to a high supply of lobsters throughout the summer.

These conditions are not sustainable for lobsters. In warmer temperatures, lobsters are forced to use more energy for respiration, and therefore have less available for feeding, growth, energy storage, and reproduction. A lobster’s immune response is also compromised by the warmer water, which is evident from the upsurge in occurrences of shell disease.

We must not let the current season fool us – climate change still remains a great threat to our lobster populations. Global warming rates are not slowing down; they are occurring faster than ever. The Gulf of Maine is warming faster than 99% of the rest of the ocean. In an attempt to understand climate change impacts on the lobster industry and help the lobster industry better prepare for the season, the Gulf of Maine Research Institute has started a lobster forecasting project and was able to accurately predict the late start for this year’s season.

Unfortunately, this prediction model has come too late for the southern New England lobster industry, which has all but disappeared as the lobsters migrated north in search of cooler waters. Hopefully, in the Gulf of Maine, it can be a new tool in our climate change adaptation belt.

CLF Announces Bradley Campbell as New President

May 21, 2015 by  | Bio |  2 Comment »

As a member of the CLF community, I want you to be among the first to know that Conservation Law Foundation has named a new president, Bradley M. Campbell. Brad is a nationally recognized environmental leader and energy entrepreneur who has held senior roles at the White House, the U.S. Environmental Protection Agency, and the New Jersey Department of Environmental Protection. Most recently, he served as principal of the law firm he founded in 2006.

BradCampbell

Bradley Campbell has been named CLF’s new president.

We are truly honored and thrilled to have Brad leading the CLF team. His depth of experience, national reputation, and expansive network will take our work to unparalleled heights during a critical time as we work to build our clean energy future, counter climate change, and safeguard the health and prosperity of New England communities.

For the past 25 years, Brad has been at the forefront of shaping some of the country’s most significant environmental policy and laws. A former White House senior appointee during the Clinton administration, Brad has also served as Director of the Environmental Protection Agency’s Mid-Atlantic office and spent four years served as Commissioner of the New Jersey Department of Environmental Protection. In 2006 Brad launched a law firm with a focus on issues involving the environment, energy, entrepreneurship, and science. He also founded an energy company that has developed some of the largest commercial-scale renewable energy projects in the northeastern United States.

Brad’s long experience overseeing large public agencies, developing strategic litigation, and negotiating innovative agreements has led to environmental milestones in New England and across the United States. He worked alongside CLF to initiate and negotiate the Regional Greenhouse Gas Initiative (RGGI) and recently took to the editorial pages of the New York Times to call out New Jersey Governor Chris Christie for shortchanging New Jersey residents in favor of a sweetheart settlement deal with Exxon Mobil over its years-long polluting legacy in the state, which has led to the destruction of creeks, wetlands, and other wildlife.

But even as Brad is ready to take on powerful opponents (and win), he also stands up for local communities. One of his most significant achievements as principal of his law firm included going to court on the side of a low-income community whose drinking water had been poisoned by unmitigated pollution.

Though Brad has lived in New Jersey for many years, he’s no stranger to New England. An avid sailor, Brad and his wife Katherine have sailed from New Jersey to their summer home in Maine, and he also has family roots in New Hampshire. While Brad officially takes the helm on September 8, 2015, he will be spending a lot of time in New England this spring and summer getting to know the CLF community. In the meantime, I’ll share Brad’s own words on his excitement about the future of CLF:

What the Federal government struggles to achieve in shutting down fossil fuels and securing a clean energy future for the United States is already happening in New England right here, right now led by Conservation Law Foundation. When we tip the balance in a region like New England, it has a profound impact for the entire nation and even the world. I am excited to lead CLF’s smart and devoted staff, volunteers, and community of supporters as we write a new chapter in protecting the region’s environment, communities, and future prosperity.

Thank you all for your support and understanding as we’ve searched for CLF’s next president. Thanks to your unwavering commitment to CLF, we’ve been able to continue our work without pause and have already achieved many milestones in this year.

I look forward to you getting to know Brad. He is going to be a positive force for CLF’s future direction and for the environmental and economic security of the people of New England. Brad Campbell will make a difference to all of us.

The Alternatives to New Natural Gas Pipelines

May 15, 2015 by  | Bio |  Leave a Comment

Now that we’ve made it through the winter, policymakers in Massachusetts are taking a look at the state of energy in the Commonwealth and trying to sort out what to do about the big energy policy questions currently on the table. First among these questions is what, if any, public policy support and funding should be invested in natural gas pipeline infrastructure.

How policymakers answer this question is important because now, more than ever, we must look beyond fossil fuels and ensure that our energy system is one built on the cleanest energy sources. Overinvestment in natural gas is simply a bad bargain for our climate, for consumers, and for our economy.

For several years now CLF has been calling for caution in the pipeline debate by debunking myths presented by pipeline proponents, exploring the environmental and economic ramifications of overbuilding natural gas infrastructure, and highlighting alternatives to pipeline investments. I had the opportunity this week to present CLF’s broad vision for the future of energy in New England to the Massachusetts legislature’s Joint Committee on Telecommunications, Utilities, and Energy. The plan I presented to the legislators:

1. Strategic public investment in the resource with the best rate of return for ratepayers: Energy Efficiency.

2. Strategic public investment in clean electric generation that is not tied to fossil fuel prices: Renewables.

3. Encourage the electric and gas markets to utilize existing gas storage and pipeline to meet peak gas demand.

4. Overall, the need for new gas pipeline has not yet been demonstrated, but if it occurs, we should begin with small pipeline upgrades and peak storage projects first.

5. If we still need more pipeline capacity after doing all of the above, go incremental first (by increasing the capacity of existing pipelines), and let the markets support the capital costs rather than putting them further on the ratepayers.

CLF is skeptical about new gas pipeline infrastructure buildout and efforts to put additional public money toward such projects. This skepticism is based in 1) the climate implications of entrenching gas further in our energy system, 2) the short-term economic effects of building new infrastructure when we’re not maximizing the infrastructure we already have, and 3) the medium- to long-term economic effects of fossil fuel prices dictating our energy prices.

Rather than more investments in fossil fuel-based energy, then, let’s instead invest wisely in energy efficiency and long-term contracts for renewable energy. And where the use of natural gas is currently necessary, let’s use LNG to supplement natural gas supply during periods of peak usage. Expanding our natural gas pipelines and our reliance on this carbon intensive and price volatile fuel should be New England’s last resort.

Effective, clean and economic alternatives are available now and they’re certainly a better deal for our climate and for ratepayers in Massachusetts and across New England.

My full slides and written testimony are available here and here. And, speaking of this winter, check out this paper collecting my colleague Christophe’s blog series on the energy lessons to be drawn from the performance of New England’s energy markets this winter.

Vermont is Burning the Furniture

Vermont legislators are scrambling to plug the budget – and there are plans to raid funding for heating efficiency to do that. This is troubling on many levels. It raids monies from the Regional Greenhouse Gas Initiative (RGGI) to backfill another shortage. It also comes on top of the proposal to shortchange energy efficiency as part of otherwise helpful energy legislation that would expand renewables and reduce fossil fuel use.

The end of a legislative session always brings out some of the worst ideas. It seems that as the warm weather approaches in Vermont, some lawmakers are keen to throw the furniture in the fire to eke out that last bit of heat after the woodshed is empty.

Burning furniture is burning money. Energy efficiency consistently delivers the biggest bang for the buck by reducing pollution and saving money for all of us. Smart investments should not be held hostage to close budget gaps.

A vote is expected on Friday May 1. If you are in Vermont, you can call your Senator and leave a message with the Sergeant-at-Arms at 802-828-2228 and tell your Senators to leave efficiency funding alone.

It’s Possible

A walk along Boston Harbor today reveals a waterfront that’s both beautiful and vibrant. Water taxis and sailboats skim its waters; tourists and locals stroll along its shores; fishermen catch striped bass right off the docks; and waterside restaurants brighten the evening.

It’s hard to believe that, barely a generation ago, this same harbor was in crisis, a dirty and rancid stew of raw sewage and toxic pollution. Back then, it was deemed the problem too big, too dirty, too impossible to solve. No one wanted to step up and do anything about it. But, rather than back down from this challenge, we at CLF declared we were going to take back Boston Harbor from the polluters.

And we did.

Cleaning up Boston Harbor is just one of the seemingly impossible challenges CLF has taken on – and won.

Thanks to the support of people like you, the remarkable transformation of Boston Harbor is just one of the seemingly impossible challenges CLF has taken on – and won – in our nearly 50-year history.

It was really kind of outrageous at the time that our small band of lawyers and policy advocates took on both the Commonwealth of Massachusetts and the Environmental Protection Agency – and won. No one then could have predicted that this was going to be a $4.5 billion, generational effort to rebuild metropolitan Boston’s entire water, sewer, and stormwater systems – or that our efforts to ensure clean water drains into Boston Harbor would still be ongoing today.

You can’t deny the results. Today, Boston Harbor is swimmable and fishable. Boston now has a world-class water and sewer authority and a National Park celebrating the Boston Harbor Islands. Billions of dollars were invested in real estate, producing thousands of jobs around the harbor in the process. And Boston Harbor now has its own watchdog – Save the Harbor/Save the Bay, a group CLF helped form to carry our vigilance forward.

While CLF was just the point of the spear that made all of this happen, it was a very sharp point directed very strategically.

Boston Harbor, iconic though it is, was not the first time CLF had taken on a seemingly impossible challenge. And it certainly wasn’t the last. Oil and gas drilling on Georges Bank? Stopped. A four-lane highway through Franconia Notch? Blocked. A destructive dam on the Penobscot River? Defeated. Big coal in Massachusetts? Shutting down. The largest landfill in Rhode Island flouting the Clean Air Act? Called to account. Pollution choking Lake Champlain? Getting cleaned up for the benefit of all.

And that’s the short list.

Now, today, in 2015, we are facing the defining challenge of our age – climate change. It’s bigger and more complex than anything we’ve tackled before, and it’s going to touch everything we all hold dear about New England: our communities, our environment, and our livelihoods.

But it’s not an impossible challenge, despite inaction and denial at so many levels of our government. Yes, we need international and national leadership on climate change, but let’s be clear: The real solutions are going to be forged at the state and regional levels and that’s where CLF shines. This is CLF’s moment.

Dealing with climate change is going to take every tool in our toolbox, every ounce of expertise we have, every innovative idea we can generate, and every ally we can muster. It won’t be easy, and I would be misleading you if I didn’t note that it’s already too late to head off some of the climate impacts New England will experience.

But, frankly, it’s when we’re told that a challenge can’t be overcome that we are at our most bold, our most creative, and our most tenacious. I know – because in my 30 years with CLF, I’ve seen us surmount the impossible time and time again.

What really keeps us moving forward, tackling New England’s biggest environmental challenges, is our commitment to all of you – and to people and communities large and small across New England. For nearly 50 years, people like you have been our critical partners in what’s possible. You have helped CLF close polluting power plants, clean up New England’s air and water, bolster the health of our oceans, and boost the vitality of our communities.

You are helping New England thrive – for people today and for future generations tomorrow. We’re honored to have you by our side and thank you for your commitment to making a difference.

This April, we’re seeking to raise $25,000 toward our efforts to solve New England’s seemingly impossible environmental challenges – ensuring clean air and clean water, healthy oceans and healthy communities for all. Please give, now, as generously as you can, to help us reach this goal.

 

 

 

 

 

 

Gas Pipelines — Misinformation and High Costs

Mar 26, 2015 by  | Bio |  Leave a Comment

The high cost and pollution from new gas pipelines are no secret. They deliver a clear reminder that investing in new fossil fuels is a bad bet for our energy future – bad for the environment and bad for our pocketbooks.

When costs ballooned for Vermont Gas Systems’ proposed new pipeline, the company failed to tell regulators, or the public, until months later. Vermont Gas is now facing penalties for the failure.

Unfortunately for the public, only the Public Service Department and the Company were allowed to present information during the hearing to evaluate the penalty. Since the two of them already agreed to a penalty, the proceeding took on an air of the sound of one hand clapping. A few concerned citizens resorted to waiving posters in the back of the room with questions they’d like answered.

At the hearing, a Vermont Gas executive acknowledged the loss of faith and lost credibility that resulted from not disclosing the cost increase sooner. Sadly that credibility was not restored when the same executive had to acknowledge that cost figures reported to regulators were not accurate.

A new gas pipeline is a big energy project. All big energy projects need to demonstrate that they advance the public good. With high costs and misinformation, confidence is sure waning on this project.

Smart Moves for Maine’s Electricity Grid

Mar 10, 2015 by  | Bio |  2 Comment »

Several years ago, Maine took a small but significant and unprecedented step toward modernizing its electric grid. Rather than implement a traditional “poles and wires” transmission build out to address growing electricity needs in the Boothbay Harbor region, the Maine Public Utilities Commission (PUC) approved an innovative pilot project.

GridSolar's Boothbay Pilot program is finding innovative ways to meet electricity demand without an expensive transmission rebuild.

GridSolar’s Boothbay Pilot program is finding innovative ways to meet electricity demand without an expensive transmission rebuild.

The Boothbay Pilot relies on so-called non-transmission alternatives, or NTAs, to reduce electric load in the region by 2 megawatts (MW). Using these alternatives eliminated the need for an $18 million transmission rebuild, while also improving energy efficiency, reducing greenhouse gas emissions, and saving ratepayers approximately $3 million per year. A smart move. Now, the PUC has the opportunity to take many of the pilot’s concepts statewide.

Non-transmission alternatives are, as the name implies, alternatives to the traditional way of distributing electricity. For most of Maine’s power grid, state-regulated transmission and distribution utilities, such as Central Maine Power, transmit bulk electricity from a generation source – for example, natural gas, oil, or hydro – through power lines, substations, and distribution lines to your home. To ensure reliable and constant energy flow the power grid must be continually maintained and at times rebuilt or upgraded to meet demand.

Instead of expending ratepayer dollars on expensive transmission solutions, electric power needs can be met by various NTAs, including energy efficiency, passive electric power generation closer to the consumer (like solar panels or wind turbines), and active devices that can be switched on when needed to reduce load on the grid. These alternatives create a more efficient grid and reduce total power needed.

For the Boothbay regional Pilot program, GridSolar developed just such an NTA solution. In a case before the PUC, GridSolar has petitioned to become the state’s lead developer of smart grid technologies – a new entity allowed under the Maine Smart Grid Policy Act. While PUC staff recently recommended that the Commissioners deny GridSolar’s petition – in favor of putting the coordinator’s role out to bid for proposals – their report nonetheless recognizes the value in having an incentivized actor forwarding non-transmission alternatives to utilities’ business-as-usual transmission projects.

CLF is an intervening party to this case and has advocated for the PUC to create just such a statewide NTA Coordinator. Designating this role is another small but critical step toward a more efficient and modern energy future for Maine. Another smart move on which we should all agree.

Time to Act: Guest Post by Olivia Gieger

Mar 6, 2015 by  | Bio |  Leave a Comment

Last fall, CLF, Mass Energy Consumers Alliance, and four youth plaintiffs filed suit against the Massachusetts Department of Environmental Protection for failing to fully comply with the Global Warming Solutions Act. In this guest post, one of the teen plaintiffs, Olivia Gieger, explains why she’s joined the court fight to defend her climate future.

As a sophomore in high school, I am all too familiar with procrastination. That group project assigned a month ago and now due tomorrow? We had a month; why start early? It’s a group project; won’t someone else do it? In my experience, I can tell you, those all-nighter–inducing group projects never turn out well.

Don’t be the sophomore in high school.

This 2015, we have the technology to know that atmospheric carbon dioxide levels are rising at an alarmingly fast rate. We’ve had this technology since 1960 when carbon dioxide levels were at 315 parts per million (ppm). Now they’re at 395 ppm(1). We know that this carbon dioxide is a greenhouse gas, which captures heat energy and slows its release from air. While greenhouse gases are necessary in our atmosphere and are needed to keep us warm, an unnatural amount is strikingly dangerous. More greenhouse gases mean more heat held in the atmosphere, which means a hotter Earth.

Side effects of global warming are countless, and they are happening today. Sea levels are rising. Ice caps are melting. Forest fires are raging. Downpours are constant in the Northeast, yet droughts are ever more present in the West(2).

But, really, why should I care? Melting ice caps and a couple less polar bears don’t really affect me, right? I don’t live in California, so those wildfires don’t affect me, either. But other people are being impacted by the wildfires, the melting ice caps, the rising temperatures. The scary reality is that we all are. I may not know anyone who lives in California, but that’s where my food is grown. If there are droughts and wildfires, how is my family supposed to get some of our favorite fruits and vegetables that don’t grow here in Boston during the winter? And those melting ice caps affect a whole lot more than polar bears. When they melt, sea levels rise – not just at the North Pole, but globally. This means my favorite beaches on Martha’s Vineyard will be washed away. It means my favorite restaurants and museums – even my neighborhood – here in Boston will be underwater in my lifetime.

In order to do something about these concerns, I have filed a lawsuit, along with three other youth plaintiffs, against the Massachusetts Department of Environmental Protection (DEP), because DEP has been procrastinating in fully complying with the Global Warming Solutions Act (GWSA). The GWSA requires DEP to pass regulations establishing declining greenhouse gas emissions limits for Massachusetts. But DEP has not done so. The purpose of the lawsuit is to force DEP to comply with the law, because it appears unwilling to do so on its own. Thanks to the support from my lawyers at Sugarman, Rogers, Barshak, & Cohen and Our Children’s Trust, we will ensure that DEP complies with the law.

So now my question is why? Why are we as a society being sophomores in high school about this? Why are we just waiting for someone else to solve this massive problem? We know the problems, and, better yet, we know the solutions. Using clean, renewable energy is one solution. Enough energy from the sun enters the Earth in one hour to power it for an entire year(3). This energy is unlimited, harmless to the environment, and virtually free. Sounds to me like it tops fossil fuels any day. It’s not just solar energy, however – wind power and hydropower are also unlimited and harmless to the environment. So why then are we oblivious to this? Why are we so incapable of making a change? We need to stop procrastinating. It is long past the time to include, encourage, and execute programs with wind and solar power as the energy of America. We cannot afford to be sophomores anymore; it’s time to graduate.
