In thinking about transmission pricing for a competitive electric industry, we should remember that the fundamental objective of competition is to increase economic efficiency. Improved economic...

Tools for Transition
Price-Driven Alternatives to Traditional Regulation
During the transition to a competitive market, a simple moratorium on rate increases protects customers and gives management an incentive to reduce costs. A moratorium also protects the utility from the risk that regulators might order a rate cut, leaving the utility less able to recover stranded costs.
Price caps break the link between rates and rate base and change the focus from book accounting costs to prices. Changes in price are constrained by an agreed-upon price index, coupled with a productivity offset that assumes (and thereby gives incentive for) annual improvements in productivity and efficiency.*
Target Market Prices
Establish a target year by which rates must achieve the "market" level. Regulators set the market price (or the "target market") based on available forecasts, then mandate a gradual "phase-in" of rates toward that target market. (Such a program should allow lower-cost utilities to raise rates to the target market price in each phase. Otherwise, lower-cost utilities will be at an unfair disadvantage in attracting capital.) The target year and the number and length of "phases" could reflect the time needed to recover legitimate stranded costs.
