Between B & C is located the Saskatchewan
Steam Generated Power Plant, called Boundary
Located only a few miles south of Estevan Saskatchewan
and few miles north of the North Dakota, USA
Saturday, May 14, 1960, at 1:00 PM, Plant was officially commissioned,
General A. G. L. McNaughton
Canadian Chairman of the International Joint Commission
operated a switch in front of the plant.
Hon. Tommy C. Douglas unveiled a bronze plaque to commemorate the event.
It supplies power to a huge part of Saskatchewan
and parts of the States
All the Lignite Coal used in this plant,
is mined nearby in the Estevan area
In 2003 the plant under went a major rebuild
when it was built it was a 130 ft high structure,
not counting the brick chimney
Coal was hauled in 50 ton Coal haulers, to a hopper at the Primary Crusher.
from here it drops toa conveyor to the secondary crusher.
Ready now for entry into the plant, or storage.
Carried on through the transfer house.
from the transfer house, a 200 ft+ conveyor takes the coal
to a hole in the top of the plant.
Pulverisers reduce the coal to a flour like powder,
ready to be burned.
coal bunkers 60ft tall high up in the building hold the coal.
base of the plant is brick, and sheet metal higher up.
water enters the intake chambers, travelling through revolving filters.
water enters the plant through tunnels, from the intake chamber,
through 12ft sq, 5 ton each, gates.
Between each pair of gates, water screens, cleaning the water.
the bottoms of the 3 wells in the pumphouse,
will be 60ft below the reservoir level.
2 pumps are in each well.
these drive the water through 6ft pipes, 300 yds away.
Pumphouse motors 30 tons each, 1250 hp each.
from the plant the water exits via a canal intake chamber.
