  • Power Resource Integrated Resource PlanIRP logo

    PWP's Power Integrated Resource Plan (IRP) is the long-range blueprint for providing our customers with reliable, environmentally responsible electric service, competitive rates and energy independence over the next two decades. The IRP takes into account future energy demand, advances in renewable energy resources and technology, energy efficiency, conservation, forecast changes in regulatory requirements, among other considerations.

    The IRP is developed with input from various stakeholder groups to ensure it reflects the community's shared vision for its locally-owned public utility. Throughout the drafting of each IRP, PWP encourages public participation and feedback through attendance at public meetings and submission of comments and questions to staff. The City’s Environmental Advisory Commission (EAC) and Municipal Services Committee (MSC) are updated throughout the development process and provide recommendations to the City Council before it is adopted. 

    Second IRP/Energy Roadmap Event Presentations 

    PWP recently completed its second Energy Roadmap event. PWP experts and consultants presented compared renewable and conventional energy resources for Pasadena’s future energy plan. They discussed how different scenarios could impact your bill, affect your electric service and benefit the environment. PWP also presented feedback collected from the IRP survey. Copies of the presentations are available below.

    The first Energy Roadmap event was held in August 2014 and was designed to kick-off a series of public meetings about the IRP. During the meeting, held at the Laemmle Playhouse 7 Theaters in Pasadena's historic Playhouse District, PWP showed a series of videos about the IRP process. We've now combined the videos into one, comprehensive educational piece for everyone to enjoy. The video explains why Pasadena needs an IRP, where the Pasadena’s energy comes from and how it is delivered to customers. It explains the pros and cons of conventional and renewable energy; how Pasadena sets its energy-use goals and how customers can help by adopting energy-efficiency measures and taking advantage of PWP-offered rebates.

    2014 IRP Update

    PWP has initiated a process to review and refresh the power IRP for the 2015-2034 planning period. The purpose of the IRP is to evaluate and optimize PWP’s portfolio of energy supply resources, including energy efficiency and demand response, in order to meet our customer’s electric needs while balancing various critical but sometimes competing objectives including system reliability, fiscal responsibility, and environmental stewardship.

    There are a number of important regulatory, market and infrastructure issues and changes that need to be reviewed and addressed in this 2014 IRP Update. PWP will work with a Stakeholder Technical Advisory Group with representatives appointed by the Mayor from a broad cross-section of constituencies. PWP will again utilize its website, customer surveys, and a series of public meetings to ensure a robust public involvement process.

    The key policy and tactical issues that will be addressed in the 2014 IRP Update include, but are not limited to:

    • Review of Pasadena’s greenhouse gas emission reduction goals and assessment of possible alternatives;
    • Review of Pasadena’s renewable portfolio standard goals and assessment of possible alternatives;
    • Use and disposition of PWP’s existing contracts for coal-fired generation, including the accelerated closure of the Intermountain Power Project and repowering with a natural gas fired generator as proposed by the Los Angeles Department of Water and Power;
    • Local generation needs, including GT-2 repair or replacement options and other options to meet local capacity requirements established by the California Independent System Operator;
    • Assessment of other local resource alternatives and incentive programs, including solar, distributed generation, energy efficiency, and demand response programs; and
    • Assessment of potential cost effective energy storage alternatives.
