Long-term thinking is a key to sustainability

CEA members are implementing new technologies and forming new partnerships to reduce emissions and adapt to climate change:

Carbon credits help the City of Medicine Hat offset the impact of power generation

Each year, the City of Medicine Hat’s landfill composting program turns 20,000 tonnes of organic waste into finished compost. Removing this material from the landfills reduces the amount of methane generated, and reduces CO2eq emissions by 13,000 tonnes annually. In addition, because bio-solids and yard waste were previously tipped and buried in the landfill, removing this material qualifies for carbon credits which are used to offset carbon emissions and other environmental impacts from the City-owned electric generation facility.

EcoLogo certification recognizes Brookfield Renewable’s low-emissions portfolio

In 2013, 90 per cent of the energy generated by Brookfield Renewable Energy Group’s assets located in Canada came from low-emission hydroelectric and wind facilities. Harnessing naturally abundant renewable energy sources is the prime focus of Brookfield Renewable’s portfolio. As of 2013, a total of 21 Brookfield hydroelectric facilities in British Columbia, Ontario and Quebec have received EcoLogo certification, a globally recognized standard indicating the highest level of adherence to rigorous and scientifically relevant environmental criteria.

Manitoba Hydro studies the impact of climate change on the electricity sector

Manitoba Hydro is participating in four projects under Natural Resources Canada’s Adaptation Platform, which brings together government and industry to collaborate on climate change adaptation. These projects include developing a methodology for projecting climate change impacts on storms and floods for dam safety, incorporating the results of climate change impact assessments in new infrastructure development, and contributing to a two-year national study looking at how increasing temperatures can affect future energy demand across Canada.

Maritime Electric finds better ways to integrate wind into the grid

In 2013, Maritime Electric Company, Limited built the infrastructure required to connect a new 30 MW wind farm on Prince Edward Island, a project that will reduce greenhouse gas emissions and increase the proportion of PEI’s electricity that comes from renewable sources. Maritime Electric continues to be involved with PowerShift Atlantic, a coalition of utilities, government and academic institutions focused on finding better ways to integrate wind energy into the electricity grid, with pilot programs for residential and commercial customers underway across the Maritimes.

NB Power installs first-of-its-kind electric thermal storage technology

Electric thermal storage (ETS) technology, which converts off-peak electricity into heat that can be stored for later use, could help integrate renewables in a more cost-effective way by improving the way peak demand is managed. To evaluate the potential of ETS equipment in residential settings, New Brunswick Power Corporation installed approximately 500 ETS room heaters in customers’ homes across the province, the first large-scale demonstration of this unit in North America.

NTPC delivers Northern Canada’s first-ever LNG facility

In 2013, Northwest Territories Power Corporation began construction of Northern Canada’s first liquefied natural gas (LNG) plant which will provide customers throughout the region with a cleaner, more affordable power source. By using natural gas instead of diesel to generate power for the town of Inuvik and its surrounding communities, this facility is expected to eliminate almost 6,000 tonnes of CO2eq emissions from the atmosphere each year.

Nova Scotia Power commissions biomass co-generation facility

In July 2013, Nova Scotia Power Inc. commissioned a 60 MW biomass co-generation facility adjacent to a pulp and paper mill in Port Hawkesbury. The project is another aspect of Nova Scotia Power’s strategy to diversify its generation portfolio and meet renewable energy requirements. The facility will supply roughly three per cent of Nova Scotia’s electricity needs and act as a source of firm renewable energy that will also help back up the province’s extensive network of new, intermittent wind generation.
