The carbon capture and storage facility at SaskPower’s Boundary Dam Power Station was online for 99 per cent of May, according to data released by SaskPower on Tuesday.
The facility came offline for seven hours due to an inadvertent compressor outage.
In the previous 12 months, the facility had been online for 79.4 per cent of the time.
The CCS facility captured 67,694 tonnes of carbon dioxide (CO2) last month, which is about 67 per cent capacity, and the average daily capture rate was 2,184 tonnes. The peak one-day capture rate was 2,423 tonnes.
Unit 3 at Boundary at Boundary Dam produced nearly 120 megawatts of power per day last month.
In the first five months of this year, the CCS facility captured 294,364 tonnes of CO2, and it has captured 3,375,816 tonnes of CO2 since it came online in October 2014.
A scheduled 14-day outage began June 7 to inspect and clean the equipment as well as perform some upgrades.
