On May 24 and 25, 2023, we hosted our fourth annual Energizing Efficiency Conference. The Conference surpassed our goals from last year, making it a resounding success.

The event was sold out and brought together over 324 delegates, sponsors and showcase participants. It provided a thought-provoking opportunity for entertaining discussions and an inspiring atmosphere to envision a sustainable future energy landscape.

The conference served to unite like-minded individuals and organizations dedicated to driving positive change in the energy sector. Through networking, collaboration and knowledge sharing, the event created a sense of collective responsibility and urgency in addressing the impacts of climate change. Attendees were inspired by the diverse range of perspectives and expertise offered by our lineup of speakers.

"Customers’ increased interest in clean energy and the electricity sector’s focus on decarbonization to reduce the impact of climate change will energize our future,” said Lori Clark, President and CEO of NB Power. “The Energizing Efficiency Conference provided a tremendous opportunity to ensure we aren’t taking a siloed approach to the global issue of climate change here in New Brunswick, but rather taking every opportunity to come together and to share ideas and set a path forward together toward realistic change.”

Building Momentum

Under the theme of "Building Momentum" the conference emphasized the importance of taking continued action to reduce energy consumption and transition to cleaner sources. The speaker sessions provided valuable insights into the potential of energy efficiency initiatives and emphasized the need to adopt these practices on a larger scale. Participants left the conference with a renewed sense of purpose and determination, ready to champion energy efficiency measures within their industries and communities.

Lori Clark, President and CEO kicked off the conference and spoke passionately about the transformative impact that NB Power’s efficiency programs are having for many New Brunswickers by making their homes more comfortable and energy efficient.

Our keynote speaker Jamie Dinsmore from Microsoft Canada left us with an inspiring message of how Microsoft is moving from “pledges to progress” and striving to be carbon negative by 2030 and by 2050 to remove all historical emissions made by the company since its inception in 1975.

Volunteers and Sponsors

The success of the 2023 Energizing Efficiency Conference would not have been possible without the generous support of our sponsors, the active participation of the delegates and the hard work from our dedicated volunteers, who ensured the event ran smoothly and created an enjoyable experience for all. We extend our sincere thanks to all the employees who demonstrated their commitment to driving positive change in the energy sector. Together with other organizations’ support, your contributions played an essential role in creating an event that will leave a lasting impact on all attendees.

See You Next Year!

We are already in discussions about next year's conference and are excited to announce that the conference will be held on April 23-24.  Make sure you save the date! Stay tuned for more updates and join us as we continue to shape a sustainable and efficient future.

As a company that is committed to the safety of every employee and every member of the public, we are deeply troubled by the images that have appeared on social media showing an NB Power vehicle pushing a person involved in the Public Service Alliance of Canada strike in Oromocto today. 

This behaviour is truly unacceptable and will not be tolerated by NB Power. No NB Power employees were involved in this incident, but an NB Power vehicle was involved and therefore our reputation is at risk. 

The RCMP intervened, the truck was removed from the road and NB Power began an internal investigation immediately. The persons in the vehicle at the time of the incident were an instructor and two students who are part of a lineman training program. The instructor is employed by a private training company, and we have terminated his involvement with NB Power.  

All of our contractors are expected to uphold the same safety standards as NB Power.  We will continue to do our part to ensure the well-being of our employees and the community members we serve.

We all know how quickly the weather in New Brunswick can change and this year is no different. Over the last few weeks, we’ve had snow, rain, freezing rain and now we are experiencing some very frigid temperatures. The lower the outside temperature, the more electricity we use to stay warm and energize our homes and businesses.

This week we are asking New Brunswickers to make small changes to manage their energy use during these extremely cold days and raise awareness about how we can all help reduce our electricity use. We will put a special focus on reducing peak electricity demand, which happens between 6 a.m. to 9 a.m. and from 4 p.m. to 8 p.m. when most people begin and wind down their days. During these peak times, we use the most expensive and least green energy to power New Brunswick.

Since about 60% of New Brunswick homes heat with electricity, the province’s consumption peaks in the winter months – double the electricity needed on a warm summer day. Extreme cold puts a lot of demand on the electricity system, which means that NB Power must use the most expensive and least green energy to meet demand.

At NB Power we are also planning to cut our energy use during this period by turning down the heat and shutting off lights and equipment that are not being used.

Small changes like taking a shorter shower, running large appliances overnight, unplugging electronics not in use, and reducing the temperature in unoccupied rooms by a degree or two can make a big difference. These small changes can help alleviate pressure on our energy grid during high demand times.

Developing these small habits can help you manage your energy use during peak demand and all year long. To learn more about peak visit our website.

When New Brunswickers use less electricity, we all win.

NB Power’s hydro facilities are located along the Saint John River system. They are “run of river” facilities with very little storage capability. Storage is measured in hours, unlike larger facilities like Churchill Falls in Labrador which can store water for months. Water coming from upstream into the headponds must be used for generation at that moment, or must be allowed to bypass the dam. Put simply, the water that flows in must flow out.

The Mactaquac Generating Station at full load passes water through at 80,000 cubic feet per second. Any flow greater than that must pass through the spill gates. In 2018, the Saint John River flows at Mactaquac were more than 300,000 cubic feet per second. As a result, water at Mactaquac was passing through the spillways. At high flows, above plant generating capacity, the water coming in must be released immediately to maintain the proper slope on the headpond to allow the river to flow downstream.

Essentially the river returns to its natural state during high flow events. In order to maintain the natural flow of the river and allow the water to pass the facilities safely, NB Power has very specific operating guidelines.

Water naturally runs downhill. Increased water flow requires there is adequate slope on the river or headpond to continue the natural flow of the river. In order to accomplish this, NB Power lowers the Mactaquac headpond level at the dam to maintain this slope, thus allowing the passage of natural river flow. When the river flow decreases, the headpond level will return to normal levels.

In the lower Saint John River Basin the Reversing Falls in Saint John creates a natural barrier in the river system that is essentially the narrow end of the funnel. With the current river flows being greater than 300,000 cubic feet per second, approximately only half of that water can pass through the falls at low tide. As a result, a bathtub effect is created in the lower basin whereby the water that is not able to pass through the falls backs up and cause flooding. This is compounded during sustained high flows like New Brunswick is currently experiencing.

Higher than average snow fall in North Western New Brunswick and Northern Maine coupled with rain events has resulted in these sustained high flows.

NB Power’s highly trained staff works closely with Riverwatch, the province’s Emergency Measures Organization and communities all along the river during these events.

NB Power is constantly observing and communicating river and station conditions with the goal of operating facilities with the least possible impact on the natural flow of the river while doing everything possible to keep its infrastructure and people safe.

After the winter that just kept on giving, the signs of spring are welcome as we put away our snow shovels for another season. With temperatures starting to warm up across the province, this is also the time when many New Brunswickers are closely watching rising water levels in the rivers and in some cases, already dealing with flooding

Now that the spring freshet is upon us, NB Power has been hard at work with the New Brunswick Emergency Measures Organization and other local partners monitoring ice conditions, snow pack, precipitation accumulation and weather patterns.

How it works

NB Power operates six run-of-river hydroelectric generating stations across New Brunswick- the largest being Mactaquac. Run of river facilities depend on the constant flow of the river. To generate electricity, the water flowing into the station is directed down and through turbines, providing the energy to spin the generators. Run-of-river stations have no ability to hold back water. All water that comes into the station must go out - especially during the spring freshet when water flows are higher than normal.

Hydro generating stations like Mactaquac contribute energy to our grid year-round, but sometimes during the spring thaw we have more water flowing into our stations than we’re able to generate. When all of the turbines are operating at full capacity in the station, operators open the spill gates to let out this excess water.

Ice Jams

Ice jams on the other hand do hold back water and ice from moving freely downstream. Ice jams have been the cause of major flood events in the past here in New Brunswick, like those in Perth-Andover, Fredericton and St. George.

These jams happen when the ice in the river breaks up, sticks together and hits the bottom of the river. Like an iceberg in the ocean, what we see from land is only the tip of the ice jam in the river. Once the ice jams, it interrupts the natural flow of the river and the water behind it backs up, causing water levels to rise. Some areas of the river are more likely to experience ice jams than others.

Here are a few other factors that can contribute to ice jams:

• Two rivers joining, like the Tobique and Saint John rivers
• Elements like islands, low bridges and sharp bends can narrow or block the path for ice movement
• Thicker ice in the river
• Shallow areas of river

Severe flooding happens when those factors combine with the following:

• Speed and volume of river flow
• Strength of ice cover
• Snow depth
• Precipitation
• How quickly the temperatures rise

Be safe

It is so important for people to stay away from the water and ice near these hydro stations in the spring. Ice may appear to be solid, but is inconsistent due to changing water flows below. Calm water on the river below a hydro station can quickly turn into rapids with a strong undertow.

Watch for warning signs, boom, buoys and barriers around NB Power hydro stations.
