The opposition is raising concern about possible expansion of carbon capture technology at Boundary Dam in Estevan.
NDP critic Cathy Sproule says natural gas is a cheaper alternative to using costly carbon capture at Boundary Dam 4 and 5.
She says SaskPower has put millions of dollars into wasteful carbon capture.
SaskPower minister Dustin Duncan says the province will use due diligence in determining future power projects with carbon capture.
Duncan says carbon capture technology had its best month ever in October, taking more than 85 thousand tons of CO2 out of the environment.
He adds carbon capture is far better than any carbon tax.
