The Challenge

The Challenge

Outgrowing Manual Rate Case Processes

Alliant Energy, a large Midwestern utility serving over 1 million customers, faced a significant strain on its resource bandwidth as the frequency and data complexity of rate cases increased. For decades, the utility relied on manual spreadsheets and subject matter experts to deliver analysis. However, this traditional approach made it difficult to:

  • Address Growing Complexity: The utility lacked the modern tools needed to meet the evolving expectations of customers and regulators.
  • Analyze Bill Impacts: Modernizing rate designs requires detailed bill impact analysis by customer segment, which was challenging to produce manually.
  • Defend Cost Recovery: Because residential fixed charges had not increased in a decade, Alliant needed to address regulatory concerns regarding equitable cost recovery and affordability for low-income segments
The Solution

The Solution

Full Population Analysis with GridX Analyze

Facing a fast-approaching filing deadline, Alliant implemented GridX Analyze to modernize its testimony preparation. The platform provided:

  • “Always-On” Analytics: Rather than relying on ad-hoc reports, the team gained full population analysis that precisely evaluated bill and revenue impacts for every single customer.
  • Advanced Scenario Modeling: Alliant modeled multiple TOU rate variations—including structures with demand charges—and compared current rates against proposed designs with high accuracy.
  • Automated Data Validation: The platform identified and filtered poor data sets before analysis, ensuring high-quality results and avoiding time-consuming rework.
  • Segmented Illustrations: The tool effectively illustrated how both volumetric and flat-rate charges would impact unique usage levels and low-income assistance recipients.
