This document outlines a preparatory study on transmission options for Pasadena Water and Power's Optimized Strategic Plan. The overarching plan aims to achieve 100% carbon-free electricity by 2030 while maintaining affordability, reliability, and rate equity. This study specifically explores increasing import capability through transmission expansion to access diverse carbon-free resources, improve system reliability and resiliency, and reduce reliance on internal generation. It identifies challenges related to long project timelines and emphasizes the importance of long-term planning for infrastructure right-sizing.

This document details a public town hall meeting concerning Pasadena Water and Power's Integrated Resource Plan (IRP). The IRP serves as a comprehensive, long-range blueprint designed to ensure a reliable, environmentally responsible, and affordable electricity supply for Pasadena. A central objective is to achieve 100% carbon-free energy by 2030, in accordance with the city's climate emergency resolution. The plan addresses critical areas including maintaining power system reliability, ensuring affordability and rate equity for consumers, and enhancing the system's stability and resilience. Key considerations within the plan encompass transportation and building electrification, energy efficiency initiatives, and the integration of distributed solar and storage solutions.

Pasadena Water and Power's strategic initiative, exemplified by the Marengo Charging Plaza, is a concerted effort towards a sustainable, carbon-free future for the community. The initiative focuses on enhancing electric vehicle adoption by providing accessible charging facilities and incentives for purchasing EVs and installing charging infrastructure at homes and businesses. This comprehensive approach aims to deliver environmental benefits by reducing greenhouse gas emissions and economic advantages to citizens through cost-effective transportation.

This Power Delivery Master Plan serves as a 20-year roadmap to ensure reliable and economical power flow for Pasadena. Key objectives include enhancing system reliability by reducing outage frequency and duration, improving system resiliency for quick recovery, and maintaining high power quality by adhering to industry standards. The plan addresses the modernization of the grid to integrate new technologies such as solar, electric vehicles, and battery systems, and proposes initiatives like replacing aging substation equipment, upgrading subtransmission systems, converting 4KV circuits to 17KV, and implementing Advanced Metering Infrastructure (AMI). The financial commitment for the plan totals $223 million for the first five years, with an additional $480 million projected for years six through twenty.
