Job Posting: Electricity Production Cost Modeler

California Energy Commission

Electricity Production Cost Modeler

$7,671.00 - $9,490.00 per Month

Final Filing Date: Until Filled

Job Description and Duties

The California Energy Commission seeks an Electric Generation System Specialist I (will consider an Energy Analyst) in the Energy Assessments Division’s Planning and Modeling Unit in its Supply Analysis Office.

The Energy Assessments Division assesses California’s electricity, natural gas, petroleum, and transportation systems and trends to provide information to the state’s decision makers and the public. These assessments inform the development, and implementation, of energy policies that balance the need for adequate resources with economic, public health, safety, and environmental goals.

The Planning and Modeling Unit analyzes electricity system operations under different demand, operation, and policy scenarios using a production cost model. Specifically, we use PLEXOS, which is distributed by Energy Exemplar. Production cost models simulate electricity system operations based on loads, generation resources, policy constraints, operational constraints, and economic considerations. The Planning and Modeling Unit currently models all 8,760 hours in the year for the Western interconnect, with a focus on California, looking out approximately 10 years.

We are expanding our modeling efforts to look further into the future and to include capacity expansion modeling as well as stochastic modeling to test system reliability in support of California’s policy goal of reaching 100 percent carbon free grid by 2045. To meet these challenges we are developing expertise to run capacity expansion models and stochastic analysis. Capacity expansion models are used to select new resources needed to meet future load, by evaluating numerous possible additions over a subset of hours in a year. Sacrificing the granularity and robustness of a production cost model, and to evaluate significantly more options. Stochastic modeling analyzes numerous changes to one or more of the production cost model inputs to determine how weather effects, varying load, and generator outages can impact system operations and to estimate loss of load probabilities.

This position will have two core responsibilities. The first core responsibility is developing, maintaining, and improving the analytical tools and methodologies used for processing inputs for and outputs from electricity production cost model and system capacity expansion model simulations. The second core responsibility is collecting, reviewing, and processing electricity system data for use in the models.

The Planning and Modeling Unit has 9 team members with varying levels of experience from 8 months to 25+ years doing production cost modeling and electricity system planning and analysis. Experienced members of the team are vested in coaching and developing new team members. Team members perform much of their work independently or in small teams. This work is then shared with the group before adding it to the simulation model. As a result, members of the team regularly work together to evaluate inputs and assumptions, think through optimal modeling methods, and evaluate results from these changes.

Please review the Minimum Requirements (or minimum qualifications) within the Class Specification and ensure that your application package clearly indicates how you meet the minimum qualifications.
