A BALANCED APPROACH
SaskPower has taken a multifaceted approach to meet our climate change goal and we
are on target to reach our 1995 commitment to reduce net greenhouse gas emissions to
1990 levels. We are making our operations more efficient, working with our customers
to find efficiencies and making investments in CO2 offset projects.
SaskPower reduced or offset over 750,000 tonnes of greenhouse gas emissions in
1997. With the dedicated efforts of our employees, we are well on our way to achieve

THE COMMITMENT
RIO DE JANEIRO, BRAZIL
Canada joined world leaders at the Rio Earth Summit in 1992, committing to reduce
emissions to 1990 levels by the year 2000. To reach that goal, the federal government
introduced the National Action Program calling for voluntary actions to limit or reduce
greenhouse gas emissions.
KYOTO, JAPAN
In 1995, world leaders agreed their initial 2000 goal was inadequate to stop global
warming. An historic agreement to cut emissions of the six main greenhouse gases was
made in December 1997 in Kyoto, Japan. Canada agreed to reductions of 6 per cent
below 1990 levels by years 2008-2012, as well as cooperation in research on reduction
actions and their impacts. The Kyoto Protocol was endorsed by 160 countries and is
open for ratification between March 1998 and March 1999.
The protocol commits developed countries to make legally binding reductions in their
greenhouse gas emissions. Currently, Canada’s First Ministers are studying the impact
of emission reductions on all aspects of society as they develop both immediate and
long-term actions. A number of National Issues tables will assist both federal and
provincial governments in their efforts. SaskPower is taking an active role in these
national discussions, directly participating in both the electricity and enhanced
voluntary action tables.

We’ve taken a multifaceted approach to meet our climate change goal — involving
supply-side, demand-side and offset projects. Our report identifies:
• internal actions taken by SaskPower in the generation, transmission and
distribution of electricity;
• consumer initiatives that reduce the demand for electricity; and
• offset opportunities found outside SaskPower’s power generation

Greenhouse gases directly emitted by SaskPower’s facilities consist primarily of CO2
(99.99 per cent), with the remainder consisting of small amounts of methane (CH4)
and nitrous oxide (N2O). Carbon dioxide is the common unit of measurement for
greenhouse gas emissions. In 1997, 14.5 million tonnes of greenhouse gases were
emitted by SaskPower’s facilities, however mitigation efforts resulted in emission
reductions of over 750,000 tonnes.

EMISSIONS BASELINE
SaskPower’s 1990 emissions baseline is 13.3 million tonnes of CO2 equivalent. The
baseline has been adjusted to account for favourable hydro conditions in 1990 and the
addition of Shand Power Station, which was approved prior to Canada’s commitment
to greenhouse gas stabilization, yet not operational in 1990. Actual emissions in 1990
totaled 10.6 million tonnes of CO2 equivalent including nitrous oxide and methane
emissions.

Between 1990 and 1997 SaskPower’s greenhouse gas emissions increased at a faster
rate than expected due to increased demand for power. By 1997, SaskPower’s
generation had increased approximately 25 per cent — over 17 million kilowatt hours.
Without SaskPower’s voluntary action plan, greenhouse gas emissions for 2000 is
estimated to be 14.5 million tonnes.

volume of greenhouse gas emissions per unit of thermal energy. Greenhouse gas

Reservoirs, which depend on spring runoff and rainfall for their supply,
provide the cooling water for most of SaskPower’s coal-fired power station
condensers. High temperatures, poor quality, and insufficient lake levels
can affect condenser performance. A monitoring and regular cleaning
program minimizes heat rate losses and reduces CO2 emissions.
SaskPower conducts an ongoing program to clean the condenser at each

Department of Health. A core component of the project is staff training
and the installation of energy-saving devices.
The South East and Pipestone health districts are participating in the pilot
project. The Pipestone Health District chose a self-managed approach to
energy saving and has trained staff to perform basic energy audits. The
South East district is using an external energy-service company to perform
audits and retrofit the district.
The South East Health District shows potential for energy savings of close
to 2 million kilowatt-hours annually. Following two years of planning and
