Regulatory
When your organization requires an independent opinion on accounting, rate, and regulatory issues, we deliver expert testimony, economic analysis, and technical information to support your rate case.
Our regulatory services include economic analysis and expert testimony before regulatory bodies. We provide:
-
We provide expert witness testimony at the Federal Energy Regulatory Commission, state regulatory commissions, and in arbitration and litigation proceedings as an expert witness for rate, economic evaluations, and accounting matters.

We will support your regulatory filing by providing analysis of the cost of service and economic issues. Our analysis provides the support for inclusion of used and useful assets in rate base, cost of capital implications, and just and reasonable rate designs.
-
Our experience with the accounting involved with developing revenue requirements leads to analysis and testimony regarding the inclusion of decommissioning costs and impairments in rates, the appropriate application of regulatory accounting (ASC 980/GASB 62), and other accounting issues that arise through the regulatory rate case process.
-
We provide intervenor support with analysis and testimony of economic, cost of service, and accounting issues in rate filings.
