1 Optional tariffs appear to possess most of the attributes George Pleat discussed in "Pricing and Profit Strategies for a Stand-Alone Electric Distribution Company," PUBLIC UTILITIES FORTNIGHTLY, Jan. 15, 1997, p. 20. For example, as Mr. Pleat recommends, optional tariffs: (1) use two-part tariffs consisting of an access charge (flat charge as Mr. Pleat terms it) and usage fees; (2) allow the usage charges to vary by season; and (3) are based on marginal costs, price elasticities and the costs of competitive alternatives.
2 According to Michael Porter, a noted expert on business strategy, success or failure for a company depends upon either delivering product at the lowest cost, or developing unique benefits that enable the company to differentiate itself from its rivals and sell its products for a premium price. (See Porter, M., Competitive Advantage: Creating and Sustaining Superior Performance, The Free Press, New York, 1985).
3 The cost of the competing alternative is computed as the levelized cost of optimally sized generation unit for each market segment.
4"Anti-Competitive Impacts of Secret Strategic Pricing in the Electricity Industry," by William Shepherd, PUBLIC UTILITIES FORTNIGHTLY, Feb. 15, 1997, p. 24.
5 See for example, California Public Utilities Commission Decision 92-11-052, November 23, 1992.
6The usage charges can be allowed to vary by season or by time-of-use.
7For ease of exposition, the optional automatic tariff is described as if there is only one usage charge. The method is also applicable to time-of-use tariffs that have multiple usage charges.
