Power Integrated Resource Plan

The Power Integrated Resource Plan (IRP) is Pasadena’s 20-year blueprint for ensuring reliable and environmentally-responsible energy, at affordable rates. The IRP is based on an industry-standard, 20-year planning horizon and is updated every two to three years. Our Renewable Portfolio Standard (RPS) of 50% by 2030 is PWP’s commitment to a sustainable energy future.

The City Council adopted the latest plan in June 2015, and the next iteration of the IRP will be developed in 2018. This IRP will comply with SB 350 (de León). SB 350, which was signed into law on October 7, 2015, requires that load serving entities with load greater than 700 GWh, such as PWP, to develop an IRP by January 1, 2019 and requires updates to the IRP every five years. The SB 350 requirements are in addition to any internal IRP recommendations. On July 7, 2017, the California Energy Commission released a draft Guidance Document on IRP Requirements that was approved in final form on August 9, 2017. For more information, visit the CEC Requirements website.

2015 IRP Goal Highlights:

  • Eliminate the use of coal-based energy by 2027.
  • Achieve a 60% reduction in greenhouse gas (GHG) emissions by 2030.
  • Support Pasadena’s renewable energy target of 40% by 2020.
  • Reduce Pasadena’s energy load by more than 1% annually, which is one of the most aggressive energy efficiency goals in the state.

Renewable Portfolio Standard (RPS):

As part of our Power Integrated Resource Plan, PWP has committed to procuring 40 percent of the power the City generates from renewable energy sources such as wind, solar, geothermal, biomass, and small hydroelectric resources by 2020.

In 2011, SB X1-2 mandated utilities (including publicly owned utilities) to provide 33% of its power through renewable resources by 2020. This 33 percent renewable energy goal is commonly called a Renewable Portfolio Standard (RPS). SB 350, which was signed into law on October 7, 2015, enhanced the RPS requirements. Further demonstrating California’s commitment to clean energy, SB 350 increases the required use of renewables to 50 percent of all power sources by 2030. PWP achieved an RPS of 32.5 percent in Calendar Year 2016.

As PWP continues to expand our portfolio of renewable energy, we are well positioned to meet our voluntary IRP goal of 40 percent by 2020 as well as state-mandated renewable energy requirements.
