Archived Power Integrated Resource Plans
PWP updates its Power Integrated Resource Plan (IRP) every few years. We have made significant progress towards achieving the goals established in previous IRPs, including the repowering of local gas-fired generation, reducing reliance on energy from its coal-fired power plant, and increasing procurements of renewable resources to meet 40% of retail sales by 2020. Review our archives for documents from our past IRPs.
2018 Power IRP
Pasadena’s 2018 IRP, one of the earliest to be produced in California that is compliant with the ambitious environmental targets of SB-100, was approved by the City Council on December 10, 2018. Developed through an extensive community stakeholder process designed to evaluate resource planning options that would best balance system reliability with fiscal responsibility and environmental stewardship, the 2018 IRP recommends carbon-free long-term resource commitments, elimination of coal-fired generation, and aggressive greenhouse gas (GHG) emissions reduction targets. View the 2018 Power IRP Document.
Strategies include:
- Achieving the Renewable Portfolio Standard (RPS) target of 60% by 2030 as required by SB-100
- Meeting the California Air Resources Board’s recommended GHG emissions reduction planning target of at least 75% below 1990 levels by 2030
- Eliminating coal from PWP’s power portfolio by June 2027
- Non-participation in the Intermountain Power Renewal Project, a 50-year natural gas coal facility replacement project
- Meeting local energy needs without any new long-term contracts for fossil-fueled resources
- Utilization of a Social Cost of Carbon for long-range planning purposes (as a dispatch penalty in the production cost model)
2015 IRP Goals & Accomplishments
The 2015 IRP reaffirmed PWP’s commitment to environment stewardship by implementing goals that have exceeded California state mandates:
| Recommendation | 2015 IRP Goal | Status |
| Renewable Energy: RPS | 40% by 2020; meet/exceed mandated level | On track:
Expect 32.5% for 2017; Expect to meet 40% by 2020. Additional procurement ongoing |
| Coal Power Displacement | Eliminate coal from portfolio no later than 2027 | On track:
IPP coal facility will convert to a natural gas facility as early as 2025. Entered into a renewal agreement with IPP on 1/16/17 |
| Upgrades to Existing Generation | Continue to maintain and upgrade Glenarm Unit (“GT”) 2 | On track:
Feasibility study for GT-2 repairs is complete. Staff recommends repairing the unit. |
| New Local Gas-Fired Generation | Replace Broadway power plant with comparable new combined cycle plant by 2015 | Complete:
GT-5 project came online December 2016, at 71 MW (gross) & 68.8 MW (net) |
| GHG Emissions Reductions | Reduction of at least 60% from PWP’s 1990 levels by 2030 | On track:
39% GHG emissions reductions as of 2016 |
| Energy Savings | Reductions of 1% of annual net energy load | On track. |
| Additional Demand Response | Add 2.3 MW per year | Project on hold, due to cost and implementation hurdles |
| Renewable Energy: Local Solar | Community Solar Pilot Project by the end of 201 | Project on hold, due to cost and implementation hurdles |
| Renewable Energy: Feed in Tariff for Renewable Resources Inside the City | 5 MW by 2020; 10 MW by 2017
Establish Feed in Tariff by end of 2016 |
Project on hold, due to cost and implementation hurdles |
