LAYOUT 10/30/98 9:21 AM Page 3 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 S askPower is a reduction of 1.2 million tonnes by the year 2000. one of the first corporations to • In 1998, we signed our first large-scale cogeneration energy contract. Over the next 25 years, SaskPower will purchase 210 megawatts of power from the Meridian Cogeneration Project, providing a clean, safe and reliable source of power for the people of our province. The project has the potential to offset CO2 emissions by 280,000 tonnes per year. • Our Condie/QE transmission line began operating in October 1997, improving the efficiency of power flow and reducing CO2 emissions by 96,000 tonnes per year. • Our improved generating facilities are decreasing the amount of greenhouse gases being produced per unit of thermal energy.

Kelly Staudt Acting President & CEO SaskPower 1 LAYOUT 10/30/98 9:21 AM Page 4 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. 2 LAYOUT 10/30/98 9:21 AM Page 5 S A S K P O W E R ’ S C L I M AT E C H A N G E G O A L To reduce net greenhouse gas emissions to 1990 normalized levels by 2000. CO2 reduction: 1.2 million tonnes 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 and distribution system.

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. 3 LAYOUT 10/30/98 9:21 AM Page 6 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. GREENHOUSE GAS EMISSIONS Estimated emissions without voluntary action plan.

Ongoing C O N D E N S E R C L E A N I N G 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 unit, using a combination of mechanical and chemical methods. CO2 reduction: 86,600 tonnes/year Planned ADDITIONAL COAL-FIRED EFFICIENCIES A number of initiatives are under way to improve the quality of operation at SaskPower’s coal-fired thermal stations. Upgrades and improvements that will enhance power generation while reducing fuel needs, include: new software to provide feedback for efficient boiler and turbine operation; improvements in soot-blowing to reduce ash buildup form the boiler walls; optimum fuel and air mixing and coal-quality measurements; major turbine overhauls; and higher steam pressure operation.

Potential energy savings of over 1.7 million kilowatt-hours were found in 51 facilities in the 1997/98 season — a significant increase from 1996. Since the program was initiated in 1995, 163 rinks have participated in the program. Audits identified an average energy savings of about $3,700 per facility. CO2 reduction: 1,370 tonnes/year Ongoing H E A LT H C A R E E N E R G Y M A N A G E M E N T In 1994, a pilot project to identify potential energy savings in healthcare facilities was initiated by SaskPower in partnership with Natural Resources Canada, SaskEnergy, Saskatchewan Energy and Mines and the 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 development, nine facilities in the district underwent energy retrofits in 1997.

The Greenhouse Emissions Management Consortium project involves collecting greenhouse gas produced at a 45 acre landfill located in the town of Groton, Connecticut. A fuel cell converts the methane to electricity and heat. A commercial five-acre greenhouse uses the electricity from the fuel cell. The experience gained from the project will help evaluate new offset opportunities. PROTECTING SOILS, FORESTS & GRASSLANDS SaskPower is working to preserve and restore natural habitat in our province to offset any land taken out of its natural state as a result of electrical generation or transmission facilities. These efforts to protect and expand habitat that captures CO2 from the atmosphere help to offset greenhouse gas emissions. Ongoing SHAND GREENHOUSE Since it’s completion in 1992, SaskPower’s Shand Greenhouse has produced 1.6 million seedlings for distribution throughout Saskatchewan. Located near Estevan, the greenhouse draws on excess heat from nearby Shand Power Station to propagate trees, shrubs and other native plants. Each year thousands of seedlings are distributed through TREEmendous Saskatchewan for conservation projects across the province. More than 300,000 seedlings were grown in 1998 with a planned increase in production of 30 per cent over the next five years. Committed to increasing public awareness, Shand Greenhouse’s educational programs — Seedling is Believing and Tree and Kids — focus on the relationship between electrical generation and the environment, encouraging children to not only plant trees but also reduce electrical consumption.
