Dear Ms. McCarthy: 

When we last communicated in November, we took the opportunity to clarify the situation with 

our Boundary Dam carbon capture and storage project. At the time, we were addressing technical 

and mechanical issues that we encountered in our first year of commercial operation. 1 can now 

assure you that we've addressed those issues and performance at the facility has improved 

considerably since. 

In fact, we captured more carbon dioxide in November 2015, just over 60,000 metric tonnes, 

than any month since the process was launched in October 2014, and we beat that total again in 

December 2015, capturing more than 61,000 tonnes. We also recently completed nameplate 

testing, where we successfully tested the capture limits of our facility, capturing 3,240 tonnes per 

day for three consecutive days representing 90% of CO2 emissions. So far, we've captured 

540,000 tonnes of carbon dioxide since October 2014. 

We continue to identify and address mechanical and operational issues on this first-of-its-kind 

process, and we're confident we have the expertise and experience to keep on track with our 

goals. We are now operating the facility in a way that meets Canadian federal emission 

regulations, and satisfies the volume needs of our carbon dioxide buyer, which involves 

capturing approximately 2,700 tonnes per day. The design and demonstrated maximum capacity 

of the process can reduce carbon dioxide by 90%, or one million tonnes a year. We will operate 

at various levels to be mindful of costs and long-term system performance. We plan on capturing 

800,000 tonnes of carbon dioxide in 2016. 

We have received much interest at home and abroad about the performance of the facility. We 

have begun publicly posting performance updates on our website at saskpower.com . We plan on 

continuing these updates throughout the year.

Thank you for your continued interest and support of SaskPower's carbon capture and storage 

initiatives. Saskatchewan has demonstrated a commitment to the environment and to its residents 

by investing and innovating in this technology. This investment has the potential to benefit not 

just Canada but numerous countries that will continue to burn coal as a source of power for the 

foreseeable future. 

It would be an honour to host you for a visit to the facility in Estevan, Saskatchewan, Canada if 

you would ever like to witness the project first-hand. 

Sincerely, 

M.J. (Mike) Marsh 

President and Chief Executive Officer, SaskPower
