New CIPEC Oil and Gas Sector Task Force Chair brings expertise in energy policy and efficiency
“My long-term goal is to influence the deployment of new technologies and projects in the oil and gas sector that can achieve significant energy savings and greenhouse gas (GHG) emission reductions,” says Jamie Callendar, CIPEC’s incoming chair for the oil and gas sector. Callendar, an environmental engineer with the Energy Innovation Team at Encana Corporation, brings a great breadth of experience and knowledge to CIPEC that will help him achieve this goal.
After graduating from the University of Waterloo’s Environmental-Chemical Engineering Co-op Program, he became the Director of Technical Services at Blue Source Canada, a carbon offset project development and environmental consulting company. Now at Encana, Callendar oversees the development of technology solutions that can economically improve the environmental efficiency of Encana’s operations. He is also the Chair of the Technology for Emissions Reduction and Eco-Efficiency (TEREE) Committee at Petroleum Technology Alliance Canada (PTAC).
It was through his work with PTAC’s TEREE Committee that Callendar first became familiar with CIPEC. With PTAC, Jamie has gained appreciation for the role that collaborative partnerships play in supporting the implementation of energy efficiency and emission reduction projects and in enabling information sharing to help overcome the many barriers that impede such projects.
Callendar brings practical experience in deploying energy efficiency projects in the oil and gas sector at Encana as well as expertise in environmental policy and energy economics.
As chair of the oil and gas sector task force, Callendar hopes to address what he sees as a knowledge gap in the sector in order to take full advantage of opportunities for energy efficiency: “There are a large number of greenhouse gas emission reduction projects that could be implemented in the upstream oil and gas sector at relatively low abatement costs, or costs per unit of GHG reduced, especially those that relate to the mitigation of venting or flaring of methane.”
“As a CIPEC member, I hope to learn from the many effective CIPEC Leaders and their successful energy efficiency projects,” says Callendar. “Moreover, I believe it will be immensely beneficial to be exposed to different energy technologies and best practices from other sectors outside of the oil and gas realm, which may be transferrable.”
Vale Thompson’s commitment to energy efficiency embedded in all projects
Vale Thompson, a CIPEC Leader in the Mining Sector, operates the Thompson and Birchtree underground mines in northern Manitoba. The company also has a 10,000-tonne per day capacity mill, a smelter and a refinery that produces more than 68,000 tonnes of 99.9 percent pure electrolytic nickel annually.
According to Wayne Schroeder, Manager at the Thompson site, more energy efficiency projects have been undertaken in the last five years and more are still on the horizon. Schroeder credits the company’s ongoing commitment to energy efficiency to the company’s sustainability vision and its fruitful partnership with Manitoba Hydro’s Power Smart program.
In 2013, for example, four small, efficient trim compressors replaced the two older, less efficient models. “Now we can run one or two compressors at a time and stay within the efficiency curve,” says Schroeder. Later in 2014, one of the mine’s large compressors failed and was replaced with two smaller efficient units with projected annual energy savings of 1.5 million kilowatt-hours (kWh). Both projects, based on verified savings, were executed with incentives from Manitoba Hydro.
Many other smaller projects have also been completed including steam trap audits to identify malfunctioning traps and an ongoing lighting retrofit that is replacing fluorescent T-12 lamps with more efficient T-8 lighting. “These smaller, lower-capital projects collectively reinforce the energy bottom line,” says Schroeder.
In terms of water conservation, the company has turned to thicker tailings in order to draw less water. The project has been successful by significantly elevating the percentage of solids and generating energy savings because less pumping is required.
Pumps on the river pump house will soon be retrofitted with variable frequency drives so that they can match water demand to output. More accurate meters will be installed in the pump house to gather baseline data.
Schroeder notes that most proposed capital projects that the company is considering are evaluated with energy efficiency in mind. To collect and disseminate energy efficiency project ideas, Vale Thompson holds company-wide events such as the 2013 savings initiative that challenged his location to save $100 million. The company also publicizes certain sites’ energy and water efficiency gains throughout its various locations. “It is one of our corporate policies to develop a greener footprint,” says Schroeder.
Weston Foods attributes significant gas savings to RETScreen Plus tool
“My goal is to broadcast the RETScreen project at our Sudbury bakery and roll out the same process across the entire company,” states Darren Borden, Energy Management Engineer at Weston Foods (Canada) Inc. A few years ago Borden and Anatoli Naoumov of GreenQ Partners solved a gas consumption issue using the RETScreen Plus software developed by CanmetENERGY, leading to savings of 50,000 cubic metres (m3) of natural gas annually.
The Sudbury facility burns over 800,000 m3 of gas per year in its production of 14,600 tonnes (t) of bread and 3,000 t of rolls. In 2013, data indicated a consistent jump in the bakery oven’s gas consumption in the third business quarter of recent years – a jump that resulted in a 25 percent loss in oven efficiency. “Something strange was going on, but we were not able to discern anything even when we adjusted for weather,” says Borden
With RETScreen Plus Borden and Naoumov were able to group individual business quarters using the software’s built-in cumulative sum (CUSUM) analysis to look at trends and isolate the precise period of the jump in gas consumption: “We could look at three years of the same months (e.g., October, November and December) of gas consumption.”
Once the period was isolated, Borden noticed that the jump in gas consumption coincided with the annual oven maintenance period and investigated this further. He found that the external contractor’s resistance-temperature detector (RTD) probe, which adjusts oven temperature, had not been calibrated regularly causing a maladjustment that led to excess gas consumption. Moreover, a closer look at oven maintenance practices determined that the cleaning and adjustment of the burners themselves was not optimal. “We were giving away gas by overcooking the bread,” says Borden.
Once the issues were identified, the solution was easy. “We developed a better tool in-house to clean and tune up the less accessible burners at the back of the oven,” says Borden. Moreover, third-party calibrators are now required to show a certificate of recent sensor calibration. This change alone is saving the bakery about 15,000 m³ of natural gas per year. “The burners now have the perfect air–gas mixture, the oven is burning at an optimal temperature and our gas use is back to 21 m3 per hour, which is what it was when the oven was installed.”
An increased level of maintenance and attention to details has paid off for the Weston Foods bakery, and as Borden notes, the issue would not have been discovered without the detailed RETScreen Plus analyses.
Canadian Malartic steps up to plate for community engagement
The Canadian Malartic Mine, located in Malartic, Quebec, is run with a long-term social, economic and environmental vision. As Amélie Foucault, Canadian Malartic Mine’s Community and Public Relations Adviser notes, the company is an integral part of life in Malartic and the surrounding region.
Canadian Malartic is Canada’s largest open-pit gold mine and has recently discovered another ore body that could extend the mine’s life until 2028. The mine is owned by the Canadian Malartic Partnership created by Agnico Eagle and Yamana Gold. The mine extracts 250,000 tonnes of mineral ore every day and employs nearly 700 people from the city and the region.
Over the years, the Canadian Malartic mine has contributed in a multitude of ways to the community. “We work with the community to develop projects that respond to its needs,” says Foucault.
The Canadian Malartic Partnership also contributes to a fund (Fonds Essor Malartic Osisko (FECM)) that aims to improve the quality of life for the citizens of Malartic now and in the future. In addition, the mine adds $25,000 to finance special projects such as projects that support the long-term sustainability of the municipality. As an example, a donation from the FECM fund helped in the creation of a fitness centre for the Malartic firefighters.
The company also prides itself on working to minimize the impacts of its activities. For example, it monitors wind direction in order to avoid dust produced by the mine’s blasting to move towards the city. Since the mine pit is close to the city, the company has constructed a green wall and taken other measures to limit noise pollution. The reclamation of the company’s old mine sites, using thickened tailings technology, is ongoing with a total of 860 hectares to be revegetated. “Our intention is that, by the time the mine shuts down, people in the region will enjoy a natural site with parks, lakes, hiking and cycling paths.”
Foucault says that the Canadian Malartic Partnership works with community organizations that best understand the needs of Malartic. “We believe that working together with such groups, as well as the municipality, we can have the most positive environmental and social impact.”
