Return on Equity: A Survey of Recent Rate Cases From State PUCs
in the early years of the new century. According to the Connecticut commission, CL&P had reinforced that notion by its own testimony regarding the cost of its pension plan. The decision notes that the company had testified that long-term expectations of returns for its pension plan (with assets devoted 70 percent in equities) should be lowered from 9.25 percent (as in 2002) to 8.75 percent, for the rate case test year.
How the Survey Was Conducted
This year's survey covers determinations of the cost of equity capital as made by state PUCs during the period from Oct. 1, 2003, through Sept. 15, 2004. The survey method remains similar to past years. Requests for information on the results of recent rate proceedings were sent to both regulators and utility financial officials. Direct examination of the commission rate orders, where available, provides additional information.
The traditional cost-of-service rate case remains the most obvious source of information on how utility regulators view the issue of shareholder earnings requirements. Nevertheless, other proceedings may contain findings relative to ROE, and those rulings are reported here as well, including cases that deal with performance-based rate plans, periodic earnings reviews, and special proceedings to determine revenue requirements for restructured electric "delivery-only" utility operations.
