Reliability and Market Operations Engineer

  • 250 Outcropping Way, Folsom, CA 95630, USA
  • Full-time

Company Description

The California Independent System Operator (ISO) manages the flow of electricity across the high-voltage, long-distance power lines that make up 80 percent of California's power grid. We safeguard the economy and well-being of 30 million Californians by operating the grid reliably 24/7.

As the impartial grid operator, the California ISO opens access to the wholesale power market that is designed to diversify resources and lower prices. It also grants equal access to 25,865 circuit-miles of power lines and reduces barriers to diverse resources competing to bring power to customers.

The California ISO's function is often compared to that of air traffic controllers. It would be grossly unfair for air traffic controllers to represent one airline and profit from allowing that company's planes to go through before others. In the same way, the California ISO operates independently—managing the electron traffic on a power grid we do not own—making sure electricity is safely delivered to utilities and consumers on time and reliably.

Job Description

Under the general direction of the Manager, the Reliability and Market Operations Engineer Operations Engineer provides engineering support to Reliability Coordination as well as Real-Time Grid Operations and Market Operations.  Responsible for establishing and updating the operating limits to the Grid, documenting the associated operating procedures to support the safe and reliable operation of the system and modeling the market impacts of transmission constraints. Participates in the development of ISO policies and methodologies associated with the reliable operation of the transmission grid and the efficient operation of the ISO market. This is a 24x7 rotating shift position.
