Utility Ratemaking & Rate Case Support
We deliver clear, defensible rate filings that combine technical precision with practical strategies utilities can implement confidently and sustainably.
Atrium provides comprehensive support across the entire ratemaking process, helping utilities build clear, defensible, and implementable filings. We develop revenue requirements, cost-of-service studies, and rate designs that balance technical rigor with operational practicality. Our expertise spans normalization, forecasting, and advanced rate structures including various time-varying rates and the regulatory mechanisms to support them such as decoupling. We help prepare testimony, manage discovery, and support settlement negotiations to achieve workable outcomes. Atrium’s strength lies in pairing deep technical modeling with strategic storytelling—ensuring that complex economics are presented in ways that build confidence with stakeholders. By blending precision with pragmatism, we help clients secure results that support financial integrity, customer value, and long-term operational reliability.
