Summer of Power #3

Today SaskPower took a number of the summer students, little over 30, for a tour of the Boundary Dam Power Station and of the Shand Greenhouse.

Boundary Dam produces 822 Megawatts (according to the people giving the tour the website says differently) of power which is about one third of the total output possible by SaskPower. It is a coal power plant and it burns about 15,000 tons of coal a day. There six generators in the plant built between the late 50's and late 70's. The are trying an experiment to make the coal "clean" by trapping the CO2 emmisions. I beleive the eventually want to store it underground in now empty natural gas pockets. This first challenge is acctually removing the CO2 out of the emmisions from the plant. Below is a picture of the inside of the plant showing one of the 150 Megawatt generators. The plant was pretty hot and fairly dirty there is coal dust on just about every surface as the powder the coal into a fine powder before injecting it into the furnaces which allows it to burn faster, hotter and more efficently.
Next we went over to Shand Greenhouse which is near the Shand power plant which is also coal powered. The greenhouse is one of SaskPowers intitives to be more "green." They give away the plants they grow to none profit organizations and groups and for educational opportunities such as schools. They grow mostly native plants to Saskatchewan many of them trees but also brushes such as chockcherrys and saskatoon berries. It was a neat little place and they have grown a large amount of plants over the years. They give out about 400,000 to 500,000 plants per year. Overall it was not a bad trip and interesting to see some places a person does not normally see. Here is a couple of other pictures from the greenhouse; one inside and another of an area to where plants that have been moved outside.
