What is rate case analysis for utilities?
is the regulatory submission process by which utilities (power, water, gas) justify their multi-year capital investment programme to a regulator and obtain authorization to recover the cost through customer rates. The submission must show the investment is prudent, necessary, risk-based, and the lowest reasonable-cost path to required service levels. The Gartner Market Guide for Asset Investment Planning Solutions (G00781827, December 2024) names rate case analysis as an explicit AIP use case for utilities.
