SaskPower delays “clean coal” power
SaskPower, a provincial Crown corporation, announced that it will rebuild its aging Unit 3 at the coal-fired Boundary Dam power plant near Estevan, Sask.
The company said a decision on a fully integrated carbon-capture and storage facility will have to wait until it gets more details on emissions regulations from Ottawa.
"We do need to get some clarification and certainty of what the feds are going to do," Robert Watson, the president of SaskPower, said, noting the federal government has jurisdiction to regulate emissions.
"It would be irresponsible to not... look at the regulations and find out what's in them so that there are no surprises," he added.
Clean coal and the ability to capture greenhouse gas emissions from large polluters for storage underground are key planks in the federal Conservative government's plan to address climate change.
In 2008, Prime Minister Stephen Harper was in southeastern Saskatchewan to tour the Boundary Dam where the federal and provincial governments are spending hundreds of millions of dollars working on a clean coal project.
That pilot project is separate from the Unit 3 upgrade.
Saskatchewan would need the technology to work on a large scale.
Per capita, the province is the largest emitter in the country due to its reliance on burning coal to generate electricity.
It has the second-highest greenhouse gas emissions per capita of any jurisdiction in the world — 72 tonnes per person annually — according to the Saskatchewan Environmental Society.
The company estimates it would cost $1.2 billion to rebuild Boundary Dam 3 as a fully integrated carbon-capture and storage unit.
Instead, refurbishing the 45-year-old unit to extend its life by another 30 years would cost an estimated $354 million.
"We're going to rebuild it so it's carbon-capture ready," said Watson. "It will come out as almost a brand new unit that's the latest technology set to capture carbon. Then, the second phase of the decision is to have the carbon-capture infrastructure built in order to capture the carbon. That's the delay.
"It's a deferral or a delay," he quickly added. "It's not a cancellation by any means."

Carbon capture: How can we remove CO2 from the atmosphere?
BERLIN - The world is, on average, 1.1 degrees Celsius warmer today than it was in 1850. If this trend continues, our planet will be 2 – 3 degrees hotter by the end of this century, according to the Intergovernmental Panel on Climate Change (IPCC).
The main reason for this temperature rise is higher levels of atmospheric carbon dioxide, which cause the atmosphere to trap heat radiating from the Earth into space. Since 1850, the proportion of CO2 in the air has increased from 0.029% to 0.041% (288 ppm to 414 ppm).
