ROE Survey & Database

(November 2007) Fortnightly's annual rate-case analysis reveals a new trend at state PUCs involving return-on-equity rate allowances. Regulators increasingly are giving utilities an earnings incentive to pursue preferred investments.

(November 2006) Our annual return on equity (ROE) survey broadly shows a continuing decline in the level of debate over issues specific to restructuring of the electric market. It also reveals a subtle shift back to investor requirements and overall business risks faced by regulated companies.

(November 2005) The results of annual survey of rates of return on equity authorized for major electric and natural-gas utilities—based on a sample of the retail rate cases conducted by state public utility commissions—show a vibrant and perhaps growing interest in traditional rate-of-return regulation.

(November 2004) Fixing an appropriate rate of return on equity (ROE) for electric utility investors marks a fundamental component of the typical cost-of-service rate case conducted across the nation by state public utility commissions (PUCs). The following survey demonstrates the results of such cases, as observed over the past year.

(November 15, 2003) With most restructuring efforts at a standstill in the energy industry, state public utility commissions (PUCs) have tended to shift their attention back to the art and science of ratemaking. For electric and gas utilities, that has meant a renewed emphasis on the mechanics of setting a maximum allowed rate of return on common equity (ROE).

(November 15, 2002) With interest rates at record lows, it is not surprising to find downward pressure on allowances for return on equity (ROE) set by state public utility commissions in retail rate cases. (The table presented herein shows the results of our annual survey of authorized rates of return on common equity for state-regulated energy utilities.)

(December, 2001) The results of our annual survey of authorized rates of return on common equity for state-regulated energy utilities show a continued reliance on traditional cost-of-service ratemaking in many states. At the same time the results also show that rate case filings do not dominate the field of economic regulation the way they might have in times of higher rates of inflation and prior to the advent of price cap regulation and market restructuring programs.

(December, 2000) Here are the results of our annual survey of authorized rates of return on common equity (ROE) for state-regulated energy utilities. This year's survey covers ROE determinations by state regulatory commissions during the period Oct. 1, 1999 through Sept. 30, 2000.
