2. 2 Gas Pipelines 59,000 km wholly owned 7,800 km partially owned 250 Bcf of regulated natural gas storage capacity Average volume of 15 Bcf/d Energy 19 power plants, 10,900 MW Diversified portfolio, primarily low-cost, base-load generation 120 Bcf of non-regulated natural gas storage capacity Oil Pipelines Keystone 1.1 million Bbl/d Expandable to 1.5 million Bbl/d TransCanada Corporation (TSX/NYSE: TRP)

3. 3 Trends in the Power Industry Canadian and U.S. power capital stock needs replacing The opportunity to participate in development, and the mechanics of participation, will vary by region GHG policy may accelerate the retirement of certain of the capital stock By 2020 Canada will have to……. Replace 8,000 MW of coal generation Replace 11,500 MW of old (relatively clean) generation Meet demand growth of 30,000 MW by 2020 Attain adequate system reliability while doing this Add more than 4,000 MW per year from now until 2020 Plus inadequate transmission systems Plus export opportunities In the next 15 years the U.S. will have to…… Spend $150 billion on new transmission infrastructure Spend $350 billion on new generation capacity Spend $50 billion on environmental retrofits on existing generation Retire 52,000 MW of existing capacity Build 230,000 MW of new capacity Attain adequate system reliability while doing this Add more than 15,000 MW per year from now until 2020 Source: Cambridge Energy Research Associates.

4. 4 No Emissions Compliance Costs Freely Emit CO 2 No R&D invested in storage No investment in gasification/post combustion capture technology Self sustaining Projects with CCS market price for power pays for CCS GHG Regulations are changing the Power business but not overnight… Traditional Future Bridge the commercial gap with subsidies Enable implementation of First Generation CCS20092016… 2015 20142013201220112010…2008 Moving too fast will shock market Flow-through CCS costs will cause consumer power prices to spike Caution 4 Transition Period

5. 5 Public Private Partnership (P3) Option “A cooperative venture between the public and private sectors, built on the expertise of each partner, that best meets clearly defined public needs through the appropriate allocation of resources, risks and rewards.” http://www.pppcouncil.ca/aboutPPP_definition.asp “The key questions here are how to improve the efficiency of infrastructure investment, and how to finance that investment. There is evidence from other countries that public-private partnerships can both increase the efficiency of investments and support their financing. Now is the right time to encourage partnerships between the Government … and private providers, given the climate of low nominal interest rates and the presence of large pension funds that are searching for these kinds of investment opportunities.” (David Dodge, Governor of the Bank of Canada,) 5

7. 7 TransCanada and Saskatchewan Collaboration Belle Plaine Polygeneration project  Gasification with CO 2 capture  Governments of Saskatchewan and Canada and TransCanada sharing in funding Western Transmission Grid Nuclear generation Wind

8. 8 Belle Plaine Polygeneration Utilization of low value feedstock for high grade products Power, steam, H 2, N 2 Uses Carbon Capture & Storage (CCS) Approx. $5.0 Billion (2008$) Feasibility study initiated In-service potential was 2015; on hold pending GHG policy and improved economy Belle Plaine, Saskatchewan

9. 9 Western Grid Study – Alberta to Manitoba SaskPower, AESO, Manitoba Hydro and Provincial Governments Enables large scale generation Wind, Gasification, Hydro, Nuclear Capital Cost: $3.0 B Converter Stations: Calgary, Regina and Winnipeg area HVDC technology – bi-directional 1050 km

10. 10 Nuclear Significant GHG benefits by using nuclear to replace coal or natural gas Bruce Power is currently evaluating nuclear sites in Saskatchewan and Alberta, or sites that could serve both Provinces Government of Saskatchewan’s Uranium Development Partnership’s mandate: ”assess opportunities for development of the province’s uranium industry, including nuclear power generation”

11. 11 Wind Generation Renewable portfolio standards (RPS) have been a catalyst for the rapid development of wind farms - many developments are currently unable to access financing. 12 Months Ago Wind energy in high demand Numerous development companies launched IPO and liquidation upside substantial Strong project economics Capital costs accelerating Today Developers move into build phase Sale of companies and IPO’s have failed Demand for wind energy continues to be strong Turbine availability improves and cost declines are occurring Saskatchewan wind 4000 + MWs (not considering operability issues)

12. 12 Projects: Major Risks and Mitigations MitigationRisk Development Costs Capital Costs Materials Labour Regulatory GHG & pollution Siting Fuel availability Counter-Party Credit Staged study work Pre-FEED FEED Risk sharing Counterparties Governments Seek clarity on policy and legislation Commitments and Timing Guarantees 12

13. 13 Engage Federal government Regulatory Risk sharing Advance regulatory policy and legislation Public Private Partnership (P3) Repayable Loan Agreement Significant risk sharing mechanism for development costs Areas for Saskatchewan Government Involvement 13

14. 14 L ooking to the future - Public Private participation Emerging climate change policy and technological advances presents opportunities for transmission and generation Saskatchewan government has a principle and potential role for facilitating private investment / joint ventures in energy infrastructure TransCanada’s financial strength and power growth objectives good fit with Saskatchewan’s government objectives 14
