ProHub Comment

This case guides the candidate through a structured cost reduction analysis using comparative benchmarking (Exhibit #1) to identify maintenance & construction as the cost driver, then time motion studies (Exhibit #2) to quantify specific savings opportunities. The case emphasizes the importance of moving from problem diagnosis to actionable implementation recommendations with clear risk mitigation.

Our client is Utility Co., a US-based utility company that operates on the West Coast of the United States. Utility Co. has been profitable over the last several years, and has seen relatively stable/favorable business conditions during that time. However, 2 weeks ago, regulators began pressuring Utility Co. to reduce its costs in order to improve prices/rates for customers. Utility Co. operates in a highly-regulated energy market, and is required to justify the prices/rates it charges customers through an annual process that examines a provider’s cost structure and attaches a “reasonable return” on top of its cost structure in order to arrive at prices/rates. The CEO of Utility Co., Larry “Chipper” Jones, has engaged our team to identify where and how Utility Co. can reduce its costs by $500M.

Clarifying Information

  1. Utility Co. provides both gas and electric services, but both businesses operate the same
  2. Utility Co. is a fully-integrated utility, performing all functions of the utility value chain: generation, transmission, and retail
  3. Good structure will segment the utility by activities and consider:
    • Generation: cost of fuel (e.g. renewables, gas/coal, nuclear, etc.) and efficiency, efficiency/throughput (TPT) of labor & assets (including maintenance/repairs and capital expenses)
    • Transmission/maintenance: cost of maintaining assets (e.g. power lines), construction of new assets, TPT/efficiency of labor
    • Retail: call center costs & TPT/efficiency, cost of customer billing/payment, overhead/SG&A, building/infrastructure costs, technology/systems

Utility Co., facing regulatory pressure to cut $500M in costs, must identify cost reduction opportunities. Analysis reveals that higher maintenance & construction costs (versus competitors) are driven by field worker inefficiency, with 120 minutes of addressable daily waste per worker. The solution involves performance management improvements and better job scheduling/material coordination.

Key Insights:

  1. Use benchmarking against competitors to isolate cost drivers rather than analyzing costs in isolation
  2. Normalize for underlying business fundamentals (asset age/use index) to rule out structural differences
  3. Detailed time motion studies can quantify hidden efficiency gaps in labor-intensive operations
  4. Cost reduction recommendations must include implementation risks, adoption challenges, and clear next-steps for execution
  5. In regulated industries, cost reductions directly translate to customer benefits, creating regulatory and stakeholder alignment
