Electric Vehicles: it’s all about the driving experience, fuel savings and a greener way of getting around
September 15 2016, 14:22 PM
Ask any electric vehicle (EV) owner what it’s like to drive an electrically powered vehicle and praise flows quickly- instant acceleration, smooth driving, a startlingly quiet ride and of course, substantive savings on fuel and maintenance. That’s praise enough to impress any driver, from the auto enthusiast to the non-technical commuter.
But for many EV-curious commuters, lots of questions remain. Below, we tackle some of the most commonly posed questions about electric vehicles in New Brunswick.
The newly released BMW i8 is a Plug in Hybrid Electric Vehicle sports car. The i8 will be on display at the Harvest Jazz and Blues Music Festival on Sat, Sept. 17 from 1-5 p.m.
What’s the difference between a plug-in hybrid and an all-electric vehicle? A Plug-in Hybrid Electric Vehicle (PHEV) uses both electricity and gas. It has a small battery pack for short all-electric driving distances. A Battery Electric Vehicle (BEV) is a fully electric car that never uses gas.
How long does it take to charge an electric vehicle? The answer to this question depends on a few factors:
- the battery capacity of the EV.
- how depleted the battery is.
- the charging level available.
Typically, EVs can be charged over night from a regular (120 volt) household outlet, known as Level 1 charging common used at home by EV owners.
Increasingly found in public spaces, Level 2 (240 Volts) charging stations can provide a full charge to your EV in 10-12 hours (though you may not need a full charge to get home or to your next destination.)
Level 3 charge stations (at 480 Volts), also known as DC-Quick Chargers or DC Fast Chargers, can provide a full charge in 30 minutes. For more information on charging options available for EVs, visit Plug ‘n Drive Canada.
What kind of savings can I expect?
The cost of buying a new car isn’t just in the price tag. You also need to factor in the cost of ownership. Because electric cars use electricity instead of gas, you can save thousands of dollars per year on fuel costs.
On average in New Brunswick, battery only electric vehicles cost about $300 per year to fuel with electricity compared to over $2,000 in gas costs for an internal combustion engine car. By making the switch to electric vehicles, you could reduce your transportation related CO2 emissions by as much as 84%
What are the environmental benefits of driving an electric vehicle?
New Brunswick’s cars and trucks burn more than 1.1 billion litres of gasoline each year and emit more than 2.5 million tonnes of carbon dioxide (CO2) into the atmosphere.
The burning of fossil fuels reduces air quality and produces greenhouse gas emissions. Released into our atmosphere, these GHGs are contributing to climate change, extreme weather events and health problems. Most of the CO2 emissions associated with your EV are from the generation of electricity.
By switching to an electric car you can reduce your CO2 emissions by as much as 3,000 kg per year, or about 75%. This is especially true when the electricity used to charge your car’s battery comes from low-emitting energy sources, such nuclear and hydro.
Are you thinking about buying an EV? If you already own an EV, what’s your advice for prospective EV owners?

As part of NB Power’s plan to continuously improve reliability for our customers, we are currently upgrading 1650 porcelain insulators on our transmission system.
Insulators are used on transmission and distributions systems to separate the electrically charged part of the equipment from an uncharged part of the infrastructure.
Without insulators to keep the current flowing where it supposed to be (in the conductor), infrastructure and the ground would become energized leaving the public and our employees at a great risk.
The insulators installed in areas along the coast and near industrial sites, are about 15 years old, with a life expectancy of 60 years. However, a variety of environmental factors have been determined to cause the porcelain insulators to overheat and crack, which has been the cause of a number of power outages in the southern part of the province recently.
“This work will most certainly improve reliability in the area,” said Darren Baxter, Project Lead. “These new insulators have a proven track record with 20 years of successful installations.”
The new insulators are made of glass and have a special coating designed to withstand greater exposure to the elements than the existing porcelain insulators.
“We are confident this insulator replacement project will help to significantly reduce the frequency of transmission –related power interruptions,” said Baxter. “Our crews are specially trained to ensure the new insulators are installed in the most efficient manner, to ensure top service for our customer.”
So far NB Power crews have replaced approximately 600 porcelain insulators, primarily in the Courtney Bay area. NB Power expects to have the remaining 1050 insulators replaced by spring 2017.

Since June 2015, the Association of Professional Engineers and Geoscientists of New Brunswick (APEGNB) have had their Fredericton-based head office connected to the New Brunswick energy grid through NB Power’s Net Metering Program. The Association’s Council members were inspired to explore renewable energy generation options after hearing a presentation by NB Power executives in the summer of 2014.
The members of the Association heard NB Power President and CEO Gaëtan Thomas, PEng, speak about the future of NB Power, energy in New Brunswick and trends in the electric utility business. Mr. Thomas spoke about a future that embraces renewables, smart grids, smart user systems, distributed generation and net metering. These - and other methods - will help to reduce peak demand and provide more security and flexibility in the province’s electric utility business.
Motivated by this message, and recognizing the societal need to mitigate climate change and inspire confidence in renewable energy, the Association decided to take a ‘lead by example’ approach. As a regulatory body ensuring only qualified and licensed professionals practice engineering and geoscience in the province, it was important to their members that the Association provide social leadership as an early adopter of renewable energy.
“We are the people at the forefront of new technology—from its development to its implementation,” said past President Paul Campbell, PEng. “Recent advances in solar energy and electric utility management have made active solar power a cost-effective investment for property owners. The time was right for us, as New Brunswick’s technology innovators, to show community leadership in the fight to mitigate climate change and become an early adopter of renewable energy.”
Following the energy efficiency pyramid which prioritizes energy conservation and energy efficiency, followed by renewable energy, APEGNB underwent an energy audit to identify areas to reduce the building’s energy usage and improve its energy efficiency. The evaluation found that thanks to a high-performing building envelope and two high-efficiency air source heat pumps, the overall energy use of the building was low in comparison to other similar facilities. The energy audit recommended the installation of programmable thermostats, LED light fixtures, water-efficient faucets and solar panels. Adding a renewable energy source to the building was the natural next step to reducing greenhouse gas emissions and energy costs associated with the APEGNB building.
The Association’s members decided to install solar panels and participate in the net metering program. Within a few months, the plan to install sixty 250-Watt solar panels to generate a total capacity of 15 kilowatts was in place. By late June of 2015, the panels were capturing the power of the sun and converting into energy for use at the Association’s office or, when not needed at the office, putting energy on the NB Power grid for other New Brunswick customers.
The total energy production of the solar panels at the APEGNB site is anticipated to be 18,000-19,000 kWh per year. With an annual average energy use of 52,000 Kwh per year, the new solar installation will meet approximately 35% of the electricity needs of the APEGNB building.
Mr. Campbell emphasized that for the Association, success has already been realized through the awareness of renewables raised among the public.
“Many people and environmental groups have applauded our leadership in helping to mitigate climate change. Having the largest solar array in New Brunswick has certainly raised the profile of engineering and geoscience,” he added. “We can say that on the sunniest days, our solar array generates well over 100 kilowatt-hours of energy during a 24-hour period.”

Last year, NB Power customers were served with greener, cleaner and more efficiently produced power than ever before. A record 75% of energy provided to New Brunswickers was from non-emitting sources, including nuclear. Just 25 years ago, those numbers were reversed, with fossil fuels generating the majority of our electricity. Today, foreign oil accounts for between just 1- 2% of our energy mix and this flip, in the space of a generation, is something we can all feel proud of.
We have heard consistently from customers that renewable energy is critical to our future. We have also heard that we need a slow and steady approach to adding renewable energy so that the added costs don’t drive up rates and home electricity bills. That’s why we’re managing this transition to a cleaner energy future over time.
The amount of renewable energy on the New Brunswick grid hit record highs in 2015-2016 topping out for the year at 42% overall.
We continue to lead the way with new renewable energy programs such as the Community Renewable Energy – First Nations Opportunity and another program for municipalities, co-operatives and not-for profits expected next January.
Some commenters have wondered whether investments in Point Lepreau Nuclear Generating Station will pay off in the long term, and whether NB Power ought to speed up adoption of renewables to replace nuclear energy.
It is true that our nuclear station has experienced challenges during the spring and summer months of the last three years. We have been forthright with our customers and our regulator about the challenges, the costs and how we are solving them.
However, it is also true that the station performed exceptionally well during the cold winter months of those same years, providing New Brunswickers with a consistent base load of clean energy when we needed it most. Nuclear kept our homes warm and bright during the darkest days of winter in all of the last three years it has operated.
Today, NB Power is using the best training, technology and globally-based peer knowledge to ensure the station delivers on its promise to provide New Brunswickers with safe, clean, affordable energy over its 30 year life-span. The last 3 years have taught us the need to be even more aggressive with preventative maintenance, focusing on diagnosing and fixing issues before they become problems. We are confident in this industry-proven approach and in the plan we have in place. We intend to deliver on the promise we made to our customers that Lepreau will be a key part of our energy future in New Brunswick for years to come.
Our greatest challenge now is to manage a transition to an even greener grid, adding more renewables without passing on large cost increases to customers.
While our province is a windy place some of the time, New Brunswickers need electricity all of the time. Green energy comes and goes as the winds pick up and slow, as the sun moves behind a cloud and as rainfall flows through our hydro dams.
Renewables are part of a constant balancing act with other types of electricity generation. As they ebb and flow, other stations adjust to ensure customers don’t experience brown-outs, blips or outages.
With the development of a smart grid here in New Brunswick, we are preparing for a future that includes more renewables generated locally and flowing back onto the grid, balanced by other generation. Meanwhile, we need our baseload generation, including nuclear, to be able to test and improve the performance of renewables, and also to provide customers with the safe, reliable and affordable electricity they demand and deserve.
New Brunswick continues to lead in the adoption of renewable energy while managing the delicate balance of keeping rates low and stable and starting to pay down debt.
I’m very proud of the continued transformation of NB Power into a business aimed at helping our customers stop using electricity they don’t need while ensuring what they do use is as green and clean as possible.

This is the first post in our new “A day in the life of…” series, which aims to showcase the diverse career opportunities at NB Power and the employees who thrive in these jobs.
As the morning light in downtown Fredericton starts to bleed through the windows of NB Power’s energy marketing desk, Andrew Robinson quietly sets up his work station for the day, mind already reeling with the day’s tasks and figures.
Once his system is up and running, Andrew’s day is off to a fast start. All the marketing desk employees gather for their morning meeting to discuss the factors of the day in order to keep NB Power’s electricity costs low. These factors can range from water flows, world conditions, weather, fuel prices and business opportunities.
NB Power’s Energy Marketing Desk buys and sells electricity in markets outside of New Brunswick, moment by moment, 24/7- just like the stock market. Andrew and his coworkers in the marketing desk analyze the system load forecast, information on NB Power’s generation assets and external factors to determine whether it’s cheaper to buy or sell electricity that day.
“We plan for any generator outages that are scheduled during the next few days. Once all this information is collected you need to identify any shortages or surpluses of generation for the next day,” he said.” Then determine the marginal cost of your generation and identify if there is any way to reduce that cost through purchasing or if you can sell any excess generation for a profit.”
Sometimes it might be cheaper for NB Power to buy electricity for an hour than it is to generate, while other times it’s more profitable to sell or transmit electricity for other companies. Any electricity sold to utilities outside the province goes into subsidizing rates for New Brunswickers.
“The activities in the energy marketing desk affect the bottom line of other activities in NB Power,” said Andrew. “The decisions we make have a direct correlation with buying and/ or selling energy.”
For the fiscal year 2015/16 the New Brunswick Energy Marketing Corporation generated $83.8 Million in gross margin all of which is used to lower electricity rates.
Andrew started working with NB Power while he was in his fifth year of university at the University of New Brunswick. He has worked for the company for eighteen years. He knows his duties as an energy marketer are critical for the well-being of the company. He has to meet several deadlines and manage time constraints every day.
“I love my job,” he said. “Every day is a new day and a new opportunity. I like making decisions and being responsible for my actions. This is what I most like about working in the energy marketing desk.”
The desk has employees planning and analyzing solutions in this economic nerve centre of NB Power 24 hours a day, every day of the year. Employees like Andrew make sure to take advantage of the market prices of energy, whether those prices increase or decrease.
“We always make sure to take advantage of those changes,” he said. “The market is constantly changing and here in the marketing desk we’re always learning and adapting to that change.”
