3 Internet of Things examples from 3
industries
Is the Internet of Things merely a far-fetched consumer fantasy that promises the
convenience of connected appliances and smart running shoes? Or is it a business
opportunity for companies that want to collect real-time information about almost every
aspect of their business?
We tend to hear a lot about the consumer applications of IoT, but many early adopters in
the IoT revolution have been businesses and government organizations with an interest in
collecting and analyzing data about their operations. From the temperature of equipment
to the performance of a fleet of wind turbines, IoT sensors are already delivering valuable
information in many industries. Blue Hill Research recently conducted an in-depth
qualitative research report about three Internet of Things examples, which we've
summarized in this article.

Internet of Things examples from government, utilities and manufacturing

2. Consider these three Internet of Things examples:
A US municipality has implemented smart meter monitoring for all the town’s
residential and commercial water meters. The project involved placing water meter
sensors on 66,000 devices that used to be manually read and recorded.
A US oil and gas company is optimizing oilfield production with the Internet of
Things. In this IoT example, the company is using sensors to measure oil extraction
rates, temperatures, well pressure and more for 21,000 wells.
An international truck manufacturer created a new revenue stream by outfitting
trucks with sensors for predictive maintenance. The system automatically
schedules repairs when needed, and orders the required parts for the repair. More
than 100,000 trucks have been outfitted with devices that transmit more than
10,000 data points a day for each truck.
As you can see in the table below, the data streams for each of these applications create
more than a million data points per day.
The ROI of IoT
How are these three companies converting raw IoT data into business insights and
tangible benefits? They’re using analytics to realize both direct and opportunity costs
associated with analyzing IoT data.
The US municipality that switched to smart meters for its water usage monitoring saw
immediate and sustained savings. Its data collection process evolved from a manually
intensive process (in which field technicians traveled to every meter) to one where meter

3. readings were automatically recorded and transmitted to a central database. This saves a
lot of money, both in work-hours and in field equipment, such as trucks. The town is
projecting a total savings of $28 million and a net savings of approximately $10 million
over the lifetime of the initiative.
The indirect savings came when the organization was able to make a fundamental shift to
a proactive service-oriented organization. Now the town can identify issues within hours,
rather than weeks or months. With better and more accurate data, the town proactively
reaches out to households to mitigate overuse or unexpected fees. The billing and
management teams have shifted from an internal reporting organization to a customer-
facing hub that provides residents a markedly better experience.
Likewise, the oil and gas company is able to monitor the performance of oil wells at the
end of every day or week. This allows it to identify opportunities for improvement (such as
increasing production levels) and areas of potential concern. Ultimately, the company can
take this information and disseminate it to field crews to make adjustments or repairs.The
result is reduced downtime and increased production levels. The company estimates that
it loses $500 for every hour that a single oil well is not in operation. After analyzing the
initial impacts of sensor deployment, the organization estimates that quicker oil well
repairs saves approximately $145,000 in cost avoidance per month per field.
The international truck manufacturer provides a mature example of using sensor data.
Sensors in the trucks, combined with predictive models, detect when a mechanical failure
is likely to occur. When this happens, the system schedules a maintenance appointment
for the truck based on the truck’s route and optimized for scheduled delivery times.
Further, the system orders and ships the appropriate parts to the identified service center,
and then notifies technicians about what needs to be fixed. The result is an
interconnected web of sensors and operational systems that communicate to save time
and money across the operation.
In each of these cases, bringing the Internet of Things and industrial-grade analytics
together yielded significant and persistent business enhancements. The key to extracting
sustained business value from IoT initiatives is, ultimately, sound business analytics
practices.
1st Grid-Scale Tesla Energy Storage
System In Europe Officially Opened
Source URL: https://cleantechnica.com/2016/12/08/first-grid-scale-tesla-energy-
storage-system-europe-officially-opened/
December 8th, 2016 by James Ayre
Europe’s first grid-scale Tesla Powerpack energy storage system installation was recently
officially unveiled in Somerset (England), according to recent reports.
The new Tesla Powerpack installation was designed to store the electricity generated at a

4. solar photovoltaic (PV) project located at the site. The energy storage project, which was
developed by Camborne Energy Storage, is intended to provide enough electricity to
supply for the needs of about 500 regional households if necessary.
The UK’s Energy Minister Baroness Neville Rolfe attended the recent unveiling event and
stated:
“We welcome this exciting project from Tesla and Camborne. Innovation in storage
technologies will help manage our electricity grid more efficiently, support greater energy
security and, crucially, drive down consumer bills.
“Our upcoming industrial strategy will build on this work further, working with businesses
to ensure the UK continues to be at the forefront of low-carbon technology, creating the
conditions for future success.”
Business Green provides more: “The industry has been calling on the government to
provide a clearer policy landscape for energy storage projects and take steps to
accelerate investment in the sector. However, Business and Energy Secretary Greg Clark
delivered a boost for the fledgling industry last month, delivering a speech in which he
argued energy storage and smart grid technologies would play a critical role in the UK’s
energy system in the future and launching a call for evidence on how smart systems
should be developed.”
The managing director at developer Camborne Energy Storage, Dan Taylor, commented
at the recent unveiling as well: “Camborne is pleased to have developed Europe’s first
Tesla grid scale installation by co-locating with a solar farm in Somerset, England. This
project is already commercially operational providing low carbon power during times of
high demand. Our first co-located site is an early step in the right direction, both for
Camborne and for the industry and we look forward to continuing to deliver further low
carbon power to the UK.”
As a close to this article, it’s worth noting here that Tesla’s Powerpack (and Powerwall)
prices havedropped dramaticallysince the energy storage systems first hit the market,
while energy density has doubled.
Fastned Raised EUR 2.5 Million In 4 Days
Source URL: https://cleantechnica.com/2016/12/06/fastned-raised-eur-2-5-million-4-
days/
Originally published on The ECOreport.
Fastned’s original funding came from its founders and angel investors such as the
Lubbers family (Breesaap) and Fred Matser (Flowfund). Last year, the Dutch fast charging
station company needed three weeks to raise EUR 3 million selling share certificates
on Nx’change. Now, Fastned raised EUR 2.5 million in four days.
The bond issue started Friday, Dec 2, at 9 a.m. and was fully subscribed on Monday
morning.

5. “To us this proves that people are paying attention to the commercial traction Fastned
makes, that we seem to have found a financial instrument which these investors like and
that the industry as a whole is getting into the reach of the “radars” of these people. The
public is starting to trust e-mobility as the future form of mobility and more and more
people (including these new investors) are showing trust in our company, people and
business case,” said Michiel Langezaal, co-founder and CEO of Fastned.
A couple of years ago it was much more difficult to raise money for a charging network
and Fastned had to rely on its founders and angels investors such as the Lubbers family
(Breesaap) and Fred Matser (Flowfund).
“We are witnessing a true breakthrough. The shift that is taking place is very evident in the
amount of time it takes us to raise funds. What took many months in 2014 only takes us a
few days in 2016,” added co-founder Bart Lubbers.
Money To Continue Growing
This money will enable Fastned to continue growing. Over the past two years it has been
delivering a consistent 10% month-on-month growth of kWh. This is 7 times faster than
the Netherland’s adoption of EVs. Fastned currently has 57 Fast Charging stations (of
which 55 are along the highway) and is expanding the network into cities and surrounding
countries
Big Data and IoT in Healthcare: Enabling
a Greater Good
Source URL: http://www.iotevolutionworld.com/iot/articles/427608-big-data-iot-
healthcare-enabling-greater-good.htm
Wearables typically dominate the IoT media spotlight in healthcare, sharing it occasionally
with remote patient monitoring or telemedicine. Each of these technologies focus on
individuals and what is happening for a specific person at a specific time. It’s definitely a
growing space, as Allied Market Research forecasts the size of the global IoT healthcare
market, including devices (implantable, wearable and other sensors), systems and
software (at the network, database and analytics layers) and services (with architecture,
consulting, and development) will reach $136.8B by 2021.
Imagine if sensors, software and data scientists could not only get people moving, as
fitness wearables do, but also help people learn to move correctly from a physiological
perspective and avoid injury caused by sports, exercise or manual-labor intensive jobs?
While bettering life experience for a single person at a time is an entirely worthwhile goal,
what if big data and IoT technologies could be used for an even greater good, to benefit
many, even improving childhood mortality rates? How much more impactful is an
innovation that offers insights in a collective group or even globally, in real time? This
article introduces two forward-thinking companies using technology, data and algorithms
in the healthcare space to have a real, positive impact on a larger community and globally.
dorsaVi – Addressing Muscle Pain and Injury

6. Started by Andrew Ronchi, a physiotherapist in Melbourne, Australia, dorsaVi uses
medical-grade, certified sensors, along with software and algorithms, to help people
recover from and even avoid injury in three different applications: workforce safety, clinical
situations, and elite athletics such as professional and collegiate sports teams. ViSafe is
the occupational health and safety application, used in motion studies during a consulting
engagement to measure range and effort of movement required for workers, such as
materials handling personnel in a warehouse, to perform their jobs. ViMove includes the
same sensors with different firmware and analytics, so individuals can understand how
they move and what impact those mechanics have on their body. ViMove is used within a
clinical environment, such as during a physical therapy session with a clinician, and can
also be worn by people throughout their daily activities, to capture movement data and
offer “beeps and buzzers” as feedback and reminders if they are not moving within their
optimal range of motion. ViPerform targets elite athletes between games and
competitions, to ensure they are moving in their most efficient, athletically effective and
healthy way possible.
DorsaVi products use two different types of sensors that include accelerometers,
magnetometers and gyroscopes. The first sensor measures the range of motion during a
movement, whether it’s bending, twisting or stepping. The second sensor measures the
muscle activity to indicate the level of effort exerted to make the movement. In the first
generation of the dorsaVi products, data uses WiFi to reach a local computer to run the
software and algorithms then display insights on a display. In the coming generation,
Bluetooth technology will connect the sensors to the local computer for processing then
de-identified data will go to the cloud for storage and long-term trend analysis. As with
many IoT applications, future uses of the data and insights may not be evident now, with
more value to come from data once it is available.
The US Bureau of Labor Statistics reports nearly 2.9 million nonfatal injuries in 2015 for
private employers, with 75% of those occurring in the service industries and 25% in
manufacturing. One way dorsaVi products immediately address this situation and benefit
larger groups of people is through the ViSafe solution. ViSafe starts with an in-depth
evaluation of high-risk movements taken in a typical day in a specific environment, such
as a warehouse, in a retail store, or even in logging or other heavy industrial location,
using the sensors to capture movement parameters and muscle engagement. The value
comes from follow-on analysis that identifies and recommends fact-based ways to
correct movements, make adjustments, or increase training within the business
environment to eliminate pain for workers and increase safety in the workplace. ViSafe in
particular also offers businesses a way to help their staff while improving productivity for
the organization as a whole. The dorsaVi products use real-time data to analyze
movements, offer refinements and corrections, and ultimately improve the daily
experience for individuals and groups of people.
THINKMD – Expanding Capabilities of Healthcare Workers
THINKMD is another company with the clear vision, strong technology, and growing team
to make a real impact on an international scale. As a global healthcare technology
company based in Burlington, Vermont, THINKMD offers a solution that has the potential
to extend healthcare systems into communities, neighborhoods, and homes. Their goal is
to give minimally-skilled healthcare workers more tools and information so that anyone
can play an active role in the communities they serve.
MEDSINC is the first product from THINKMD, conceived by its founder, Dr. Barry Finette,
a pediatrician at the University of Vermont. While practicing medicine in resource-poor

7. countries, Dr. Finette saw that children were dying from preventable causes that could be
remedied simply by increasing the “healthcare ability” of existing community healthcare
workers already in place. He developed MEDSINC to address this pediatric global health
crisis, with UNICEF reporting that nearly 6 million children under 5 years of age die from
preventable diseases such as pneumonia, dehydration, and infectious diseases
(Committing to Child Survival: A Promise Renewed, 2015 Progress Report). By guiding a
user through simple questions and gathering of data (vital signs, history, and symptoms),
MEDSINC immediately generates triage and treatment recommendations that can
improve health outcomes and reduce preventable childhood mortality.
“With less than two hours of training, community healthcare workers can learn the
MEDSINC platform and gather critical clinical and healthcare data on a smartphone or
tablet. MEDSINC then generates up to 20 integrated assessments as well as triage,
treatment and instructional recommendations appropriate for the user to implement in the
community or healthcare facility,” explained Dr. Barry Finette, Founder of THINKMD. “Our
technology is unique because we designed the back-end algorithms to mimic the way a
physician assesses a child. By taking a holistic and integrated approach, MEDSINC
allows for the integrated assessment of many critical diseases simultaneously.”
MEDSINC is just the leading edge of the opportunity for THINKMD. Besides giving
frontline health workers more guidance and ways to treat patients, MEDSINC is also a
data-capturing platform. With each assessment, MEDSINC captures 40-50 public health
and epidemiological data points. This data is completely de-identified, but is geo-tagged
and time-stamped, offering a public health data set for underserved regions that doesn’t
exist to date.
The potential impact of THINKMD’s data is immense. Once widely deployed, MEDSINC
will generate extremely valuable aggregated information from locations all over the
developing world. One obvious reason to mine and analyze that data is for rapid tracking
of the spread of infectious disease. Current methods require reports from affected areas,
with data captured and conveyed sporadically, often with significant delays, resulting in
gaps in information and time-shifted indications of potential outbreaks. In addition, these
methods rely on inferred data versus direct data. MEDSINC gives THINKMD direct,
patient-generated data in real time, which is captured, processed and immediately
analyzed to offer insights far more quickly and reliably than current methods. THINKMD’s
data scientists work with the aggregated, de-identified data itself, understanding the
problem they are addressing and using various algorithms and tools to find the insights
that have a significant impact globally. This is big data at its best, offering real information
that lets global health agencies and governments take action that can save lives.
CONCLUSION
Both THINKMD and dorsaVi products were the innovative ideas of medical practitioners
who recognized a need and used their expertise and commitment to fixing a problem to
both conceive impactful technology solutions and bring them to market. Similar
organizations face the same uphill battle of any technology start-up with the added
healthcare burden, with funding, regulatory requirements, payer questions and other
economic, technical and business issues. THINKMD and dorsaVi shine as two example
companies who drive to bring their solutions to market, in order to help individuals, larger
groups and even the global community.

New York Is Bringing Solar To The
Masses Through Smart Community Solar
Policies
Source URL: https://cleantechnica.com/2016/12/09/new-york-bringing-solar-masses-
smart-community-solar-policies/
Originally published on Think Progress.
By Laura A. Shepard
Americans love, love solar energy, but not everyone can wrangle a set of rooftop solar
panels. Some roofs are too small or too shady, or they face the wrong direction. Some
people are renters. Others own their home, but they can’t afford the up-front installation
costs.
These barriers, say experts, don’t have to keep Americans from cashing in on solar. If
rooftop panels aren’t right for you, you might try something called community shared
solar. Band together with friends, neighbors or your church to set up a solar array.
Everyone buys in. Everyone reaps the benefits.
Community shared is taking off, but not necessarily in the places with the most sunshine.
Rather, solar is growing in states with the strongest policy. The steps currently being
taken to advance community solar in New York make that state a prime example.
How does community solar work?
In 2015, Governor Cuomo approved the Shared Renewables Initiative to expand access
to clean energy. The initiative enables renters, homeowners and businesses to set up
shared solar projects.
Community solar projects can take several forms: One variety is community group
purchasing, where a group of homeowners or businesses jointly hire a solar firm to install
panels on their roofs. Buying in bulk cuts everyone’s costs. Another option is offsite
shared solar. These arrays usually take the form of a solar “farm” or “garden.” Any
ratepayer can subscribe to panels in the array and get credited on their electric bill as if
the panels were on their own roof. Onsite shared solar is another form of community solar.
Residents of an apartment building or tenants in a large office building can put panels on
the roof to supply electricity for everyone. And finally, there are community-driven financial
models, which involve private investors and donors funding solar installations in low-
income communities. Residents in turn reap the cost savings.

9. Credit: Department of Energy
New York utilities now credit ratepayers for the electricity produced in their name by
offsite solar projects. Consumers play a flat rate to subscribe to a solar panel or two in a
shared solar array, and they are credited on their monthly bill for the energy generated by
that solar panel. Subscribers pay month-by-month, meaning they can move away at any
time.

10. “People really want to go solar, but only one in five homes are suited for it,” said David
Sandbank, director of NY Sun, part of the New York State Energy Research and
Development Authority (NYSERDA). But with community shared solar, this is the first time
that everyone can buy in.
“Low to moderate income residents now qualify. Renters are in play now. It really widens
the demographic access,” Sandbank said. He said NYSERDA is receiving applications for
community shared solar worth hundreds of megawatts.
Shared solar arrays cost less per kilowatt than individual arrays, in part because the per-
panel cost of installation is lower. Shared solar is also eligible for tax incentives from
NYSERDA, as well and state and federal tax credits that apply to any solar installation.
“It’s a big deal and we’re really excited about it,” Sandbank said. “There’s a lot of
development because of it, and we’re bringing a lot of business to New York.”
A case study
The first shared solar project in New York state was completed in Tompkins County this
year. When community shared solar became a possibility, Renovus Solar, an Ithaca-based
solar installer, was eager to jump on the opportunity and conducted an informational
session for the community.
“Over our 12 years of business as residential and commercial solar energy installers, we’d
disqualified many roofs of hopeful solar owners due to shading issues, size constraints
etc.,” Renovus’ Emma Hewitt said. “So we knew that there were many people in this area
who wanted a community solar option and would happily become early adopters.”
Judy Hyman, a local clean energy advocate, drove all over Enfield searching for suitable
panel sites: flat, south-facing, and electrically compatible.
Renovus looked at Hyman’s notes, aerial maps, and property maps before sending out
letters to each person who owned land suited to this purpose, telling them that they might
be able to receive income from their land, defray tax costs, and help the environment.
Several property owners responded and a site was selected.
About three dozen people signed up for the solar project, which feeds into the utility grid.
The array offsets 100 percent of the power subscribers use at home.
“Community solar is about individuals claiming their power production , investing in a
clean energy system that they own. It’s the difference between owning your electricity
production versus renting electricity from the utility company,” Hewitt said. “And there are
big savings associated.”
“With energy prices increasing, the cost of doing nothing is becoming increasingly
expensive. Going solar secures a low energy rate for decades,” Hewitt said.
Before shared solar arrived on the scene, there were a lot of Tompkins residents who
wanted to solar power, but couldn’t make it work.
“People like me would’ve loved to go solar, but my house is in the woods,” said David
Bock, one such resident. When the community project was unveiled, Bock signed up. His

11. monthly electric bill is now about $15.
Net metering laws allow solar power credits to be annualized, so surplus electricity
generated in the summer is effectively carried over to winter. So, while the solar panels fell
a little short of his needs in October, they’d built up enough credits during the summer to
defray his energy costs.
“The future of the planet depends on getting us off of fossil fuels,” Bock said.
“Renewables and solar are our best option.”
Smart city transformation begins with
tangible entry points
Source URL: http://readwrite.com/2016/12/04/smart-city-transformation-begins-
tangible-entry-points-cl4/
Posted on December 4, 2016 in Smart Cities
Often lost amongst the smart cities media hype are clearly defined entry points that local
leaders can target when beginning to transform their metropolis into a smart city.
Thankfully, Tech Republic recently interviewed several industry experts for their views on
how urban leaders can begin the journey toward smart city-dom.
One key focus is to develop smart initiatives that not only solve urban challenges but get
citizens in on the action too.
“Find a point that takes citizen interest first, but can impact many people in a city and get
visibility and become a symbol of a smart city,” said TM Forum’s Carl Piva. “Ask, ‘What
can I do to make my city more equitable, more inclusive or to simply create a dialogue
with the people who live there?'”
A successful example of this is the city of Boston’s mobile app that enables citizens to
report problems or needed repairs by sending their photograph of the issue to the city.
Not only does this empower residents to participate in improving the city, but sparks
citizen dialogues around trends and recurring needs.
Another early smart city strategy is for planners to highlight a solid return on investment
(ROI) that a technology-driven project will generate.
A case in point is Los Angeles’ conversion of 215,000 streetlights to LED smart lights
which generates $9 million in utility savings annually. That the lights will pay for
themselves in six years provides clear ROI evidence to convince skeptical city
stakeholders that future smart projects promise tangible benefits.
“That streetlight is everywhere in your city and it’s got power to it and you can do so many
things with it, now and in the future, if you think big first,” said Smart Cities Council
chairman Jesse Berst.

12. Harnessing the massive flows of data generated by smart cities is another entry point for
urban transformation. Especially if that information is not only used to improve the city,
but also for engaging the public through open data initiatives.
New tech means fewer 911 calls
The decision by Albuquerque, N.M.to make certain data openly available to citizens
resulted in 422,000 fewer calls to 311. Berst says the power of open data not only cut
costs but improved city interactions in other interesting ways.
“As a city, you save money on Freedom for Information requests, and you create this data
repository that your departments can start using and your citizens can start using and
your hackers and developers can start using to build great things,” he said.
Lastly, the ability for smart city innovations to tackle government silos is a critical selling
point for transforming a city’s technology infrastructure.
“It’s very important to not build a siloed infrastructure,” said Cisco’s managing director of
Smart+Connected Communities Munish Khetrapal. “The day you build a siloed
infrastructure you’ve wasted 30% of the dollars taxpayers are spending.”
Smart city platforms are effective in breaking city staff out of vertical silos through
interdepartmental data sharing. As well, the new technology fostering horizontal
collaborations between unexpected city actors and the elimination of duplicated services.

13. Au début des années 2000, alors néo-retraité, Michel Saint-Mleux passait la plupart
de son temps-libre à des activités tournant autour d'une thématique peu commune :
la sustentation magnétique. Quelques années plus tard : une start-up voyait le jour,
avec la particularité d'employer une équipe dont la moyenne d'âge dépasse les 60
ans.
Cette start-up, baptisée Levisys, s'est spécialisée dans les volants d'inertie dédiés au
stockage d'énergie. Pierre Fessler, cofondateur et président de Levisys, raconte avoir
passé de longs moments à étudier la sustentation magnétique en compagnie de Michel
Saint-Mleux. Mais cette sustentation magnétique, qu'est-ce que c'est au juste ? C'est
une technique permettant de faire tourner à grande vitesse de lourds disques avec très
peu de frottements, donc en réduisant quasiment à néant les pertes d’énergie cinétique.
Aujourd'hui, la maîtrise de cette dernière a permis aux deux hommes d'être à la tête d'une
jeune entreprise qui pourrait bien apporter sa pierre à l'édifice de la transition énergétique.
En 2004, un petit prototype a permis à la toute jeune start-up d'être récompensée par le
prix de Jeune entreprise innovante, tandis que l'année suivante, une enveloppe de 450
000 euros aura permis d'en réaliser un second testé avec succès par EDF cinq ans plus
tard.
S'en suit l'heure des grandes expérimentations. En effet, pas moins de dix volants
d'inertie de Levisys ont été lancés au cœur du démonstrateur Smart ZAE cette année et
septembre, une première ligne pilote de production a vu le jour à Troyes, dans l'Aube.
Cette dernière devrait tourner à un rythme de 100 unités de 13,5 kWh-40 kW à l'année.
De l'énergie au freinage
Les volants d'inertie de Levisys absorbent de l'électricité en prenant de la vitesse pour en
fournir lorsqu'ils freinent, le tout avec l'aide d'un moteur-alternateur. Leur rendement est
exceptionnel : 97%. Quant à leur durée de vie, elle est est égale à plusieurs centaines de
milliers de cycles charge-décharge, de quoi recharger de nombreux véhicules électriques
à vitesse grand V ou soutenir une infrastructure électrique pendant des années.

14. La concurrence ne fait pas le poids. La qualité des volants d'inertie de Levisys
(architecture de rotor en fibres de carbone développée avec Airbus Industrie) a d'ailleurs
tapé dans l'œil d'entreprises reconnues, notamment BYD, leader de la batterie lithium-
ion, qui a décidé de s'associer avec la start-up française au mois d'octobre dernier.
Grâce à sa technologie, Levisys estime que le coût total du kilowattheure stocké sur toute
la durée de vie est de 4 centimes d'euros.
Sachant que le stockage d'énergie (électricité) est désigné comme l'un des piliers de la
réussite de la transition énergétique, nul doute que ces volants d'inertie à longue durée de
vie apparaît comme une alternative crédible à la batterie traditionnelle. Les opportunités
pour Levisys ne devraient donc pas arrêter de frapper la porte, et l’entreprise de croître de
façon « exponentielle », selon les mots de Pierre Fessler.
New York City To Get Public EV Charging
Station Pilot
Source URL: https://cleantechnica.com/2016/12/05/new-york-city-get-public-ev-
charging-station-pilot/
December 5th, 2016 by James Ayre
Following the recent approval of INT. 1124 by the New York City Council, the unofficial
capital of the northeastern US will soon become home to a new pilot program for the
buildout of public electric vehicle charging stations.
The idea behind the pilot program is to install electric vehicle (EV) charging stations in a
wide variety of popular, publicly accessible locations — such as gas stations, municipal
parking lots, parks, etc. — and thereby support broader consumer adoption.
The local embrace of EVs is targeted as a key pathway to reducing carbon emissions and
local air pollution. There are currently more than 2 million internal combustion engine (ICE)
vehicles in New York City.
The bill was sponsored by Councilman Costa Constantinides (D-Astoria), the chair of the
council’s Environmental Protection Committee.
Constantinides had this to say on the subject: “With an incoming presidential
administration that has pledged to undo our nation’s efforts to combat climate change,
cities and local governments must now lead the way on protecting our environment. New
York has already been a worldwide role model in sustainability and we must continue to
keep this work a top priority. INT. 1124 will help us reach our goal of reducing carbon
emissions by encouraging sustainable habits. A pilot program for electric-vehicle charging
stations will encourage more New Yorkers to use electric cars.”
The Queens Tribune provides more: “The program is a 2-year pilot that will place at least
two electronic charging stations in each of the five boroughs. … The New York City
Department of Transportation is projected to post the location of the charging stations. An

15. advisory committee will be established to report on the program’s cost, the rate of
utilization of each charging station, recommendations for expansion, the feasibility of on-
street charging and more.”
Overall, that sounds like a good plan. Here’s to hoping that there are substantially more
than 2 EV charging stations installed in each borough, though. The idea of possible on-
street parking is particularly interesting, a popular model in some European cities (like
Amsterdam) but relatively uncommon in the US.
