2010 供电总量 Power Supply 20759 GWh ：煤电 Coal 58%, Gas 燃气发电 18% ，水电 Hydro 19% ，风电 Wind 2% 。

46 万用户 more than 460,000 customers

电网规模： 156,000 km of power lines

人口 Population ： 1,050,000 *

面积 Territory ： 650,000 KM2

人均排放 , GDP 碳强度最高 Most carbon intensive economy in Canada


拟议中限制碳排放的法规Canada’s Proposed Emission Regulations

• 联邦政府拟议中的燃煤电厂减排法规草案 Proposed Greenhouse Gas (GHG) Regulations on Coal fired Power Plant

– 预计 2011 年颁布， 2015 年生效并针对所有燃煤热电厂 New regulations to become law in 2011 and in effect by 2015 and applicable to all coal fired power units

– 2015 年，燃煤热电厂排放量 / 每兆瓦时与高效天然气热电厂相当 (360-420 Toones/GWh) By 2015, existing coal-fired units must meet an emission standard on par with the emissions intensity of high-efficiency natural gas generation （ 360-420 kilograms (kg) of carbon dioxide (CO2) / per megawatt hours (GWh) ）

– 所有新建燃煤电厂须做好 CO2 捕集系统连接准备， 2025 年达标 Capture ready required for all new coal-fired electricity units and allow for technology development to meet the emission standards until 2025.

• 萨省政府将执行联邦法规的减排目标 , 但实施不同限排减排政策 Saskatchewan in alignment with federal government on environmental regulations

– 设立省政府监管的技术改造基金 Establish provincial fund for technology solutions– 建立减排领导监督机构 Set up administrative agency for implementation– 2012 立法有待三读实施 To be finalized 2012

• 整体运行理想与否 Will integrated operation perform as intended

• 风险模型真地对于项目管理那麽有价值，或只不过投资者释放的烟幕 were the risk models actually of value in managing the project, or is this just fodder for the financiers

• 示范项目错过的某些机会在未来能否再现Can some of the opportunities which were bypassed on the Demo be brought into future projects

• 能否发现降低成本提高效率的新契机 What new opportunities for cost reduction and performance improvements will be uncovered

• 社会在多大限度上支持向低碳过渡，并接受涨价 To what extent will society support movement to low carbon future including accepting a cost premium
