I want to congratulate the towns of Marlborough, Keene, Swanzey and Wilton for forming an electrical power buying group. This is great news for the consumer. The wisdom of former Mayor Michael E.J. Blastos has finally been realized and I am proud to have served on that Energy and Climate Committee.
The Cheshire County Community Power (CCP) electric energy plan (EAP) was recently approved by the PUC and we are weighing our options to; 1) get the lowest and most sustainable rates to power our facilities in Keene, Swanzey and Westmoreland; and 2) establish rules for towns within Cheshire County to join the CCP plan.
The state’s Community Power law allows towns in Cheshire County to piggy-back onto the CCP plan without having to establish their own EAP’s, and still realize the buying power of the entire Community Power Coalition of New Hampshire (CPCNH) load bank. The rates of that load bank will be announced at a press conference scheduled for Monday, March 13 at 3pm in Concord to announce electric rates for it’s first wave of towns that include Harrisville, Walpole and Peterborough in the Monadnock Region.
Because of the market confusion last year, Cheshire County scrambled to find a competitive rate that would protect us from the huge rate increase. We entered into an agreement – which has saved the County 35% in electrical costs – with Freedom Energy that ends this fall. We are currently looking into a transition strategy to join into CPCNH’s plan that promises to save us even more and could take effect sometime this summer.
I also want to thank the members of the Monadnock Energy Hub, Clean Energy NH and local community energy committees for their tireless efforts to promote the concept of community power in the Monadnock Region. Together we will bring sustainable, affordable and resilient energy sources to power our communities for decades into the future.
Whether it is through homeowners that install rooftop solar panels or businesses that invest in wind farms, more of us will access electricity through decentralized technologies than direct connection to the grid by the mid-2020s, according to Bloomberg NEF. While most of us translate this outlook to simply implementing more solar panels and wind turbines, that is only half the story. Decentralization has much more profound impacts in our society, including presenting consumers and businesses a choice — a choice to decide how to source their energy needs. Decentralized technologies help enable that consumer choice.
Micro grids are a key part of these decentralized technologies. The term micro grid can be intimidating, because it may mean different things to different people, so let’s break it down and highlight some of the benefits.
Let’s cover four common questions and answers about living on micro grids to boost your energy IQ.
No. #1: What is a micro grid?
A micro grid is a local energy system capable of producing, potentially storing and distributing energy to the facilities within the network. Micro grids can be made up of several different assets, also called distributed energy resources (DERs). Common DERs used to generate power are solar photovoltaics (PV), wind turbines and power generators. Energy storage systems, intelligent controls and management software are other elements of the system that provide further functionality to the micro grid. Micro grids can be connected to the centralized grid or completely off-grid and self-sustaining. With the obvious need for continuous, reliable power, healthcare facilities can be good applications for grid-connected micro grids. Remote mining sites that need a lot of energy can be great applications for off-grid micro grids.
No. #2: What is the difference between micro grids and centralized generation?
The difference can be summed up in two words; proximity and resiliency.
Micro grids are near facilities they power. On the other hand, electricity, in centralized power generation, is produced in central power plants that could be hundreds to thousands of miles away from facilities being powered. This proximity of micro grids reduces losses in energy transmission and the significant cost of installing new transmission and distribution networks.
Most micro grids deliver improved energy resiliency through redundant DERs, a combination of solar PV, natural gas or diesel power generators and energy storage systems. Depending upon the micro grid design, facilities can still be powered even if any of these DERs fail. In comparison, a failure in a power plant could put us in the dark.
No. #3: How does a microgrid work?
Intelligent controls and management software are at the core of micro grids. Many control systems can track the energy needs of the facility and determine how to supply the needed energy. These control systems consider and evaluate factors such as cost, fuel supply, weather and energy load required to decide which DERs to utilize.
As mentioned, micro grids can be made up of many different assets. The control systems are the key element to manage dispatching the best asset based on these factors. Finally, some micro grids also feature energy storage systems to capture the energy produced at one time for use later.
No. #4: Why do we need micro grids?
Sustainability
As more businesses focus on sustainability and deploy renewable energy sources such as solar PV, micro grids come to help by integrating these renewable sources into the energy infrastructure. These renewable sources become a physical part of the micro grid and the intelligent controls manage their utilization.
Economics
Micro grids feature intelligent controls that can help businesses save money and improve economics. These systems can monitor the cost of energy from different DERs and utilities, then make choices on activating the lowest cost option. They also maximize the contribution of different sources. For example, when the wind isn’t blowing, the energy storage system can be activated to utilize the energy stored from when it was blowing to meet the load. Micro grids also help businesses participate in demand response and demand charge management programs to lower their costs.
Resiliency
Micro grids improve the resiliency of the local energy infrastructure by adding redundant DERs, which provide energy to the businesses. For a grid-tied micro grid, this means local DERs, ranging from solar PV to power generators, can continue to power the businesses and facilities during a utility outage.
Micro grids will continue to play a key role in our energy future. Users can evaluate the relevancy of micro grids per their unique needs as a part of their broader energy management strategy.
Can We Go Local?
Consider the 16 square mile area centered by the Dillant-Hopkins Airport in Swanzey.
That block of area encompasses the Keene Industrial Park, Keene’s Dillant-Hopkins Airport and Keene sewage treatment plant, Swanzey Fire Dept. and Industrial Park, Monadnock Regional High School, The Cheshire Fairgrounds, as well as dozens of businesses and hundreds of residential homes. And it is serviced by a phase-3 electrical power line owned by Eversource Electric.
The City of Keene recently installed a 770 KW solar array to power the sewer treatment plant – the facility that consumes the largest amount of electricity – but was constrained by a state law that doesn’t allow solar arrays of more than 1 MW to built outside the municipality’s boundaries. This array provides much of the power consumed by the facility, but not all, and certainly not enough to serve surrounding needs, or provide the resiliency should the central grid resource go down.
A solution, and pioneer project for the Cheshire County region, would be a collaboration among the several stakeholders to build a several MW micro grid that could be managed by a cooperative joint powers agency.
The benefits of economics, sustainability and resiliency as explained above would empower local entities to realize their own energy goals.
Former state representative Paul Berch points out that the County tried to build a micro grid in Westmoreland a few years back, because of the frequent power outages there. The Public Utilities Commission turned it down because they felt it would not be cost effective, as opposed to building more transmission infrastructure as needed. Because 3-phase power is close by, I believe a micro-grid at the Dillant-Hopkins Block would meet the PUC’s LCIP (Least Cost Integrated Resource Plan) guidelines and be a perfect pioneer project.
I urge the local stakeholders to meet informally to see if this plan is something that could benefit their constituencies.
As you may know, for the past five years I have been an intervenor before the NH Public Utilities Commission in it’s deliberations concerning the expansion of natural gas as an energy source in New Hampshire.
One important fact that has come out of these deliberations is that New Hampshire law precludes natural gas companies from expanding into other energy sources, such as wind, solar or hydro. This fact makes it impossible for gas companies to consider transitioning off fossil fuels to renewable fuels that are less harmful to our environment, because it would mean putting themselves out of business.
Many people agree with me that diversifying our energy sources makes us less vulnerable to price spikes and shortages caused by global events beyond our control.
Obviously the issue is much more complicated than that, but I am suggesting a change in current legislation that could help. Simply put, an amendment to RSA 378:37 would allow energy companies who deal strictly in fossil fuels to produce electricity – and make a profit – using renewable sources.
The suggested text is highlighted in bold:
378:37 New Hampshire Energy Policy. – The general court declares that it shall be the energy policy of this state to meet the energy needs of the citizens and businesses of the state at the lowest reasonable cost while providing for the reliability and diversity of energy sources; to maximize the use of cost effective energy efficiency and other demand side resources; and to protect the safety and health of the citizens, the physical environment of the state, and the future supplies of resources, with consideration of the financial stability of the state’s utilities. To meet this policy, the commission may permit, approve and otherwise authorize utility investment in, use and deployment of such energy sources as the commission deems consistent with the policy and the utility’s resource management capabilities on such terms and conditions as the Commission deems just and reasonable, without requiring the utility to obtain such authority as may be required under Chapter 374 or otherwise; in the event of conflict with any other commission regulations, under the general regulations of Chapter 374 or otherwise, this provision of this statute shall control.
I ask that our county legislators consider introducing this amendment for consideration during the upcoming legislative session.
Recent news that major electricity suppliers like Eversource may soon begin selective blackouts to account for their short-sighted dependence on natural gas is startling and could have been, and still could be, avoided.
This news comes on the heels of the Gov. Sununu-appointed Public Utilities Commission’s decimation of the state’s N.H Saves program. This action was so ill-advised that the Legislature just passed a bill by an unheard of bipartisan, unanimous vote to negate the damage.
Ratepayers should come together and insist that the Legislature also repudiate the governor’s foolish and greedy agenda of stonewalling the advancement of renewable energy technology by lifting the cap on net metering and removing the unnecessary hurdles local community power aggregation groups are facing.
It’s no secret that New Hampshire needs to get off fossil fuels, and fast. The climate crisis is here, and transitioning to clean energy must happen as soon as possible. We can use energy efficiency, solar, wind and more to help us get there to avoid freezing our families as well as the worst climate cataclysm in recorded history.
It’s time for ratepayers to face the fact that the other key benefit of getting off of fossil fuels is building a clean-energy economy, powered by local jobs right here at home.
Because eliminating fossil fuels doesn’t only make environmental sense — it makes economic sense.

The 643.2-kilowatt grid-tied solar electric system installed atop Keene’s public works department on Marlboro St. late last year has been deemed an overwhelming success by senior staff in charge of the project.
At a rain-soaked ribbon cutting event held on site Monday, Brentwood, NH-based ReVision Energy spokesman Dan Weeks told a crowded room of officials and residents that “even today, the system is performing well, producing nearly 400kw of electricity for this facility.”
In 2018 the Keene City Council approved a resolution to generate 100% of our electricity from renewable sources, with the plan to reach that goal by 2030. The city’s Energy and Climate committee has been given until December of 2020 to complete that plan.
But, even before that happens, the city is expected to begin planning on phase two of it’s solarization project. Assistant public works director Duncan Watson said Monday that he expects a request for proposals to install an even larger array at the Dillant-Hopkins Airport will be sent out in the next few months. That array will provide power for the city’s sewage treatment facility, which is the city’s largest user of electricity.
Many in the region have argued that, since the Marlboro Street project has performed so well, it is safe to take a much bolder step and partner with other entities – towns, county government and business – to create a regional micro-grid to support additional facilities and add resiliency to the regional power supply.
Preliminary discussions between the Energy and Climate Committee (ECC) and Cheshire County government officials indicate that a partnership on energy projects could happen soon if senior city staff and council leadership were to adopt a more aggressive agenda.
The ECC has asked mayor Kendall Lane to expand the committee membership in order to invite major stakeholders like the county, school district and colleges to send voting representative to the committee. That proposal will be heard by the Keene City Council Finance Committee Thursday.
This particular initiative will go a long way in meeting the 100% by 2030 goal because other energy stakeholders will need to be engaged in the process in order to meet the city-wide goal. And, it makes sense to share resources and plans to maximize the amount of energy savings across the city.
