abbreviations “OC” and “TOC,” which were used in the testimony by Prof. Stewart C. Myers that first recommended TOC to the FERC in the Williams proceeding. (Author Kolbe assisted Myers in developing this testimony.)

4. Several factors might have contributed to alternative methods’ lack of penetration for these entities. First, these companies tend to be natural or statutory monopolies. There is no competition to speak of, hence no pressure for the utilities to adopt TOC or levelized rates. Second, regulatory commissions tend not to change unless someone can demonstrate a real need. Both affected parties and regulatory agencies must invest time and effort to change prior practice, and such investments are unlikely to happen unless badly needed. Third, pipelines and transmission lines often consist of discrete investments, while electric and gas distribution systems and water companies have traditionally tended to have more continuous investments and a smoother profile of investments by vintage. The distortions due to OC-based pricing for any given asset are diminished for companies with smooth investment profiles. Lastly, since capital costs for electric and gas LDCs represent a relatively small proportion of the final electricity or gas prices, the OC-based distortions may not have registered.

15. For example, Duke and Progress Energy listed three drivers for utility consolidation: 1) competition for capital to fund major capital investments required to replace aging infrastructure and comply with increasing stringent environmental regulations; 2) increasing customer rates in an uncertain economic environment; and 3) need for scale benefits and continuing productivity gains.
