Never Enough Power: A Journey of Innovation and Reliability

Marcie Edwards has been instrumental in driving initiatives to improve power system reliability. In the city of Anaheim, she spearheaded the construction of a peaker plant in the city center. This project was a significant step towards ensuring a stable power supply during peak demand periods.

In addition to the peaker plant, Marcie championed the development of two new substations in Anaheim, one of which ingeniously incorporates a city park on its top. These projects further demonstrate her commitment to community integration and urban development.

Marcie’s efforts also extend to renewable energy. She supported the development of Anaheim’s renewable power portfolio, starting with geothermal energy. This initiative marks the city’s transition towards sustainable and environmentally friendly power sources.

During her tenure as a board member of the California Independent System Operator (CAISO), Marcie chaired the early Market Issues Committee. Her work facilitated the creation of a competitive power market, promoting efficiency and economic benefits.

As the interim Executive Director of CAISO, Marcie played a crucial role in preventing 16 planned large-scale power interruptions, such as load shedding. Her extensive background as a generating plant operator, a power system operator (load dispatcher), and a Utility General Manager has equipped her with a comprehensive understanding of power planning issues and various market paradigms.

Marcie is well-versed in new power trading mechanisms such as Energy Imbalance Market (EIM), Resource Adequacy (RA), and Extended Day-Ahead Market (EDAM). Her expertise lies in understanding how transmission, generation, and available market mechanisms need to work together to ensure an economical and reliable power supply.

Marcie Edwards’ leadership and strategic vision continue to shape the future of power supply, driving innovation while ensuring reliability and sustainability.
