PacifiCorp 2007 Integrated Resource Plan (May 30, 2007)

PacifiCorp – 2007 IRPChapter 1 – Executive SummaryACTION PLANThe integrated resource plan is intended to provide guidance for the company’s resource procurementactivities over the next few years. To follow through on the findings of this resourceplan, PacifiCorp’s action plan includes:• Reaffirming commitments to renewable resources:– Accelerate its previous commitment to acquire 1,400 megawatts of cost-effective renewableresources from 2015 to 2010,– Increase the amount of cost-effective renewable resources to 2,000 megawatts by 2013,– Actively seek to add transmission infrastructure to deliver wind power to key load areas.Investigate adding flexible generating resources, such as natural gas, to integrate newwind resources– Enhance its integrated resource planning modeling to address renewable portfolio standardsand the impacts of adding large quantities of wind resources to its system● Increased focus on energy efficiency:– Continue to run programs to acquire 250 average megawatts of cost-effective energy efficiency,and– Add an additional 200 average megawatts of cost-effective energy efficiency initiatives● Maintaining and expanding load control programs:– Maintain and build upon the existing 150 megawatts of irrigation and air conditioningload control in Utah and Idaho,– Add 100 megawatts of additional load control split between East and West beginning in2010,– Leverage voluntary demand-side measures, such as demand buyback, to improve systemreliability during peak load hours, and– Incorporate the results of the demand-side management potentials study into the company’sdemand-side management programs and future integrated resource plans.● Studying and addressing environmental issues:– Enhance its integrated resource planning modeling to address new carbon regulations,and– Take a leadership role in discussions on global climate change and continue to investigatecarbon reduction technologies, including nuclear power.● Addressing transmission constraints:– Expand its transmission system to allow the resources identified in the preferred portfolioto serve customer loads in a cost-effective and reliable manner● Adding a diverse mix of base load / intermediate load resources:– Acquire up to 1,700 megawatts of base load / intermediate load resources on the east sideof its system for the term 2012 through 2014, through a mix of thermal resources andpurchases, consistent with the April 2007 filed request for proposal, and,– Acquire 200 to 1,350 megawatts of base load / intermediate load resources on the westside of its system from 2010 to 2014 through a mix of thermal resources and purchases.10
