Company Overview

Based in San Francisco, Pacific Gas and Electric Company is one of the largest combined natural gas and electric utilities in the United States (NYSE:PCG). In addition to providing energy to approximately 40% of Californians and 1 in 20 Americans, PG&E also delivers some of the nation’s cleanest electricity, nearly 80% from GHG emissions free sources, and 0% from coal. As an active member of the community PG&E aims to improve our customers’ quality of life, economic vitality, and prospect for a better future by providing clean, safe, reliable and affordable energy.

Team Overview

The aim of the Risk Analytics team is to enhance the risk practices of PG&E’s Electric Operation business and thereby address changing external conditions such as climate change. To this end the Risk Analytics team creates and maintains tools to enable PG&E to close the gap between metrics and electric system performance. These tools provide a multi-layered view of risk across the electric system so that decision-making processes include and empower employees at all levels of the company to manage risk appropriately.

In creating these tools, the team employs a data supported, lean solution process to expand PG&E’s ability to assess and manage risk. The result are assessments and mitigations that are more dynamic, quantitative, and customer-focused, with a multi-layered approach for both short-term and long-term time horizons.

Sample activities include:

  • Interpretation and representation of meteorological data in models that combine a range data sources such as the electric system asset data, vegetation and meteorology
  • Development of computer vision models aimed at accelerating and automating asset inspections processes
  • Predicting electric distribution equipment failure before it occurs allowing for proactive maintenance
  • Supervised and unsupervised machine learning models using Python and Spark, executed on AWS
