Acton’s electrical aggregation program, Acton Power Choice, approved by DPU

After a long delay, the Commonwealth’s Department of Public Utilities approved Acton’s Community Choice (electricity) Aggregation plan, Acton Power Choice!

The old description still applies: http://www.acton-ma.gov/powerchoice (except for the launch date).

As a summary, the Acton Power Choice program will bring to most electricity customers in Acton a new set of choices for their electricity supply. The Town, in collaboration with Peregrine Energy Group (and a dash of influence from Green Acton), designed the program and put out an RFP (Request for Proposals) for companies interested in becoming the program’s electricity supplier. Acton Power Choice will offer two options to local electricity users.

Seven companies bid for Acton’s contract. The chosen bidder was Dynegy; the initial contract period will be 24 months, after which time the Town can create a new contract that’s most advantageous. The design of Acton’s program offers two electricity sourcing options.

(1) The “default” option will feature an additional 5% Class I Massachusetts RECs on top of the mandatory Massachusetts RPS (Renewable Portfolio Standard, which is scheduled to go up by 1% each year) 12% Class I MA RECs , for a total of 17% renewable sourcing in 2017. Pricing for this “default” option will be 10.720 cents / kWh. Customers would pay this amount plus the usual delivery charge and monthly fixed fee. The Eversource basic rate, starting July 1, will be 10.759 cents / kWh. This means that the default Acton Power Choice rate will be less than the Eversource rate — even the summer rate (which is typically lower than the wintertime rate). So: significantly more renewable sourcing than the Eversource offering, and cheaper!

(2) There will also be a 100% renewable (“green”) option. This will be built with 100% Class I MA RECs and priced at 12.7 cents/ kWh, just under 2 cents more than both the default price and the Eversource price. As Green Acton works with Peregrine, we will have a lot more information with which to explain the program and calculate potential electric bills under both the default plan and the 100% green plan. Green Acton expects to have an important role in explaining and encouraging people to sign up for the 100% green option. Peregrine and Town staff are starting to work on the roll-out, and are currently estimating on a start date of late September or early October.

During the past few months, some people have been receiving misleading snail mail letters, email offers, and phone solicitations about renewable electricity that may look (or sound) like they are from some vaguely official-sounding agency. The official notices about the real Acton Power Choice program won’t be going out until late summer or early fall.

Green Acton is very excited about Acton Power Choice! We will be sharing information on the program, and will be sure to post the official letters about the program on the Green Acton website.

Acton Cleanup WEEK: April 22-29

Please mark your calendars and plan to participate.

Acton Cleanup Week: April 22 – April 29 

This year, Acton Cleanup will be a week long.

The Cleanup is being co-organized by the Acton Chinese-American Civic Society. You can learn more about them at the ACACS website.

The new site to let everyone know about streets that need cleaning, or streets that are already clean, and to sign up to clean streets, is ready now at actoncleanup.info.

 

We encourage everyone to sign up for a site and make a difference.  This service for your community can be done anytime from Saturday April 22 through April 29.

On Saturday April 29, our usual Cleanup Day crews with a list of areas needing your help will be available to give out bags and gloves, and collect the debris that has been removed from the streets and paths of our town.

Stay tuned for details!  Or contact us today at cleanup@greenacton.org .

The Swap Shop at the Transfer Station

In 2015, the Swap Shop was launched at the Transfer Station in a small new building just downhill from the main recycling area (near the Red Cross bins).

Anyone with a recycling or trash sticker can use the Swap Shop: gently used items in good condition can be donated at the shop, and items can be picked up — all for free! The purposes of the Swap Shop is to keep more objects out of the trash, and to get perfectly usable items into the hands of those who can use them.

Do you love to visit the Swap Shop? Are you a people person? Will you have a few hours this year to volunteer doing something fun? We are looking for volunteers for the 2017 season.Working at the shop is fun, social, and satisfying! The more volunteers, the more often the shop can be open for business.

To get a volunteer application, please email either Corey York (Acton’s Town Engineer): engineering@Acton-MA.gov, or Debby Andell (Green Acton member and volunteer scheduling assistant to Corey York: DebbyAndell@gmail.com.

HEET/MAPC Gas Leaks Study

 

The Home Energy Efficiency Team (HEET) worked with the Metropolitan Area Planning Committee (MAPC) to survey 15 miles of roads in each of 15 towns, including Acton, and worked on preparing a “best practices” report on getting these leaks fixed. The report is here at this link to fixourpipes.org

The survey work was completed in 2016. Green Acton obtained a copy of the leak information  via a Public Records request. The spreadsheet on leaks  is here.

They found 58 underground leaks of methane (“natural”) gas.  Some were quite large: Five on Prospect street were larger than 5,000 square feet.

To Acton Selectmen, Dec 2016: Part 1, climate change

Thanks for having us back to help start your conversation about natural gas use in Acton. There are a lot of health and safety reasons for reducing the use of natural gas, but tonight we want to focus on another reason: Climate Change.

A quick refresher: the temperature of Earth’s atmosphere is the result of many forces, including the effects shown in this diagram. When the energy coming into our atmosphere matches the energy going out, Earth’s energy is in balance. What comes in is largely visible light. What radiates away from Earth is mostly heat in the form of infrared waves. When we add additional infrared-blocking gases — greenhouse gases — to the atmosphere, more energy gets trapped, and things heat up. This is why methane, the main ingredient of natural gas, is such a problem.

Here’s an infrared photo of the gas leak at Porter Ranch in California last year. The black cloud is methane, which is opaque, and thus, blocks infrared heat waves from escaping our atmosphere. That’s why it’s such a problematic global warming gas. The International Panel on Climate Change rates methane as having more than 80 times the global warming impact of carbon dioxide over a 20-year period.

Methane leaks into the air during every stage of natural gas processing, from the original drilling to its delivery under the streets of Acton. How much methane leaks? We don’t know. This diagram shows recent EPA estimates, along with the mostly higher estimates of other independent studies. At many of these estimated leak levels, natural gas used for home heating has an even larger global warming impact than coal or oil.

Climate change is a complex process, with many contributing and interacting factors. This chart shows only a few of these factors, but it’s already too complex to go into all the details tonight. I just want to highlight two of the many types of causal loops.

 

In blue, we’re highlighting one “negative” or “control” feedback loop. The loop shows the way that increasing CO2 increases the growth of some forests, which causes more CO2 to be absorbed from the atmosphere, which then causes lowered CO2. This acts to keep climate change under control.

 

In red, we’re highlighting one “positive” or “reinforcing” loop. This loop shows increasing temperatures causing more sea ice to melt, which increases the extent of open water, which reduces the reflection of energy back into space, which causes the water and air to heat up even more. This acts to reinforce climate change.

 

It’s been very difficult for scientists to predict when the positive feedback loops will start to dominate over the negative feedback loops. When that happens, there can be a rapid increase in global warming. We may have entered such a period recently.

One of the positive feedbacks seems recently to have entered a scary new phase, in which both Arctic and Antarctic ice extent are shrinking at the same time. That’s especially strange for the Arctic; with winter coming on in the northern hemisphere, normally the extent of sea ice would be growing quickly rather than shrinking.

Here’s more evidence of a possible shift to a period of rapid change. After a slower rate of rise in average temperatures over the last few decades, each of the last 12 months has seen higher average global temperatures than ever before in the era of modern record-keeping. The red line on top shows those temps. Record-breaking high temperatures are now happening more than 20 times as often as record-breaking low temperatures. And the harmful effects are real.

High temps in Pakistan in 2015 caused more than 1,200 deaths. This photo shows a worker creating new mass graves in anticipation of the next round of heat waves. We’ve hit the era of anticipatory mass graves.

We need to do what we can to stop the use of fossil fuels, the main source of human-caused greenhouse gas emissions. How much do we need to do, and by when?

Because of the difficulties in predicting the details of how climate will actually change, different kinds of targets have been set out in scientific papers and in our laws and treaties. Achieving any of these targets would involve large-scale changes starting now. We don’t know precisely how much we need to do, but we know that the scale of the effort will need to be very large, so we all need to do what we can as soon as we can.

 

So, what can we do here in Acton?

Here’s the rough carbon footprint for Acton, circa 2010, taken from the Acton 2020 Plan. What we can do locally is to shrink each of these slices as quickly as possible. To do that we must head toward a fossil fuel–free, clean energy economy. Any investment in new fossil fuel/natural gas infrastructure locks us into using it for decades to come. And continued creation of fossil fuel infrastructure, even at a small, local scale, thwarts our Town and 2020 goals.

 

A simple carbon action plan would involve the same general steps for every pie slice.

This is our handy carbon-reduction plan. First, we need to reduce energy use. In the case of residential heating and cooling, one way is through air sealing and insulation, which are heavily subsidized by MassSave and available to all homeowners.

The next step is to move away from fossil fuel use. This is accomplished by first switching to systems that use electricity, and then working to source as much of the electricity supply as possible from renewables. And we must do this as quickly as possible.

(On to Part 2, mostly about Heat Pumps)

To Acton Selectmen, Dec 2016. Part 2: Heat Pumps

The best current technology for heating and cooling homes and buildings is the heat pump, which comes in air source and ground source varieties

Here’s what a typical air source heat pump with mini-split installation looks like. It comprises one or more outdoor pump units, and one or more indoor mini-split units, connected with small flexible pipes that carry refrigerant. Town Hall uses this technology in the new wing. You can see the indoor mini-split unit in Conference Room 9.

How do these systems work, and why are they good solutions for heating and cooling?

Heat pumps get most of their energy from the air or ground outside. Refrigeration technology takes advantage of how heat is absorbed when a gas turns to liquid, and how it’s released when a liquid turns back to gas. Even when it’s cold outside, there is still energy in the air, and modern heat pumps can extract energy down to 10 or even 20 degrees below zero, and bring it inside. For those few super-cold days that occasionally happen, supplemental heat is used, such as conventional electric heat. In hot summer weather, the cycle runs in reverse, providing air conditioning nearly twice as efficiently as other systems. The use of energy from the grid is only ⅓ to ¼ of the energy used in the system, because most of the energy comes for free from the air or the ground outside.

We’ve been talking about air source heat pumps. There are other versions:

  • Ground source heat pumps take advantage of the steady temperatures below the frost line. Though they are even more efficient than air source heat pumps, the higher capital cost of ground source systems has become harder to overcome as air source technology improves.
  • Heat pump technology can also be used for water heating, which is typically done with an all-indoor system in the basement.
  • Heat pump heating and cooling systems can use small flexible tubes to transport the refrigerant, eliminating the need to add expensive ductwork.
  • For retrofits, systems can use existing heating or AC ducts, saving on installation costs, and allowing for a single central heating and cooling unit inside.

So what’s the financial story on air source heat pumps?

Heat pump operating costs are lower than those for any other available option because of the free energy heat pumps get from the local environment. With the incentives that are available to cushion the installation costs, heat pump costs are similar to those for other heating and AC solutions. Thus, they save money as soon as they are turned on. As an upgrade from oil, coal, gas, or propane, heat pumps begin to save money — sometimes called the “payback” point — within a few years. As an upgrade from natural gas, at current gas and electricity prices, payback can take as long as 30 years. The payback period is shorter if the alternative is an expensive repair to an existing heating or AC system.

Here’s the heating part of the operating cost comparison, from a great site called “Efficiency Maine.” You can type in expected prices for various fuels and the site then shows you the expected operating cost. At typical prices, heat pumps are by far the least-expensive option.

Here’s the cooling part of the cost comparison. The key measurement is called the SEER ratio. As this efficiency rating goes up, costs go down. Heat pump systems operate at very high efficiency, with SEER ratings of 20–30 so unless you have a very new AC system, cooling with a heat pump will cost less.

Incentives for heat pump systems are available as rebates from both the state’s Clean Energy Center and from Mass Save. And a remarkable state loan program offers so-called HEAT loans, which are interest-free loans for terms as long as seven years. These can help make some upgrades cash-flow positive fairly quickly. There is also currently a 30% federal tax credit, but we don’t yet know yet whether this will extend into 2017.

You can see our recommendations here, but to summarize: It is especially urgent to prevent new natural gas infrastructure that will lock in fossil fuel use for decades. Clearly, heat pumps are part of the solution for reducing fossil fuel use in meeting Acton’s heating and cooling needs. We recommend that the Board of Selectmen affirm these goals, and via the Town Manager, direct staff and boards to educate homeowners, developers of single and multi-family homes, real estate agents, and the public on heat pump technology, and how and why to adopt it. We recommend that research be done on additional ways for the Town to discourage new natural gas infrastructure. We also recommend that the Selectmen consider tasking an existing or new town entity with creating an overall carbon reduction plan for the Town. And finally, we commend the work the Town has done already, including creation of the Acton Power Choice plan and working with the gas company to coordinate upgrades to their leaky gas infrastructure.

Thank you all for your time and your thoughtfulness on these issues. We look forward to the next part of this dialogue.

First Lego League Presentation

First Lego League 6th grade girls’ team presentation: Microfiber pollution of oceans. All from different schools. There are three parts to this team’s competition project: (1) the project they’re presenting today, for which they had to research a problem within the theme of interaction between humans and animals (“animal allies”). They chose how microfibers (tiny plastic shards from fleece clothing) can end up in the ocean, be eaten by organisms, and then move up the food chain. They did a presentation in the form of a skit; (2) a robot game, on the same theme (animal allies), in which robots have to complete missions; (3) sharing their project with their communities.

Microfibers are teeny bits of fabric, from fleece clothing, that shed in the washing machine, and often end up eventually in the oceans. Fish are eating them either directly or indirectly, and 700 marine species are in danger. The fish on our plate may contain microfibers. Microfibers have been found in beer in Germany.

Before water from washing machines goes to oceans, it typically goes through treatment plants. Yet, there are so many of these fibers in the water that even if they filter out 15% of them, the volume entering oceans is huge. Upgrading treatment plants is challenging and expensive. Scientists are working on making washing machines more efficient at trapping these fibers. The team reached out to 200 adults and a few kids and only a few knew about microfibers and their effect on the planet.

How to prevent? Wash clothes only when necessary, in full loads, in cold water, and at lower speeds/gentle cycles. Using liquid soap and fabric softeners helps. The fabric industry is researching fabrics to figure out how to manufacture clothes that don’t have this problem; Patagonia is the premier example. There is a product in prototype (available 2017) that would go into the wash and capture microfibers. Polyester (including fleece), rayon, acrylic, and all synthetic fabrics are the culprits; natural fibers (cotton, wool, linen) do not present this problem. The older the item, the more fibers it sheds. President Obama signed a law last year (which will take effect next year) that will ban the use of microplastic beads in personal care items, but that doesn’t include microfibers for fabric.

The team became interested in this problem — discovered by ecologist Dr. Mark Browne and published in 2011 —through an article they read in school. The team, which meets 3–4 times each week, was featured in an article in the Acton Beacon, and has shared its findings with the local community and the New England Aquarium. They have completed one regional tournament, and will now go on to statewide competition. The group will continue to work to raise awareness of this problem; they may do a presentation for the local schools and perhaps for the 2017 AB PIP-STEM fest.
