Electricity transmission is a real business. With more than $50 billion of net plant, another $3 billion annually in capital expenditures and yearly operating income that could reach $5 billion per year under normal circumstances, the power grid is roughly twice the size of the natural gas pipeline industry. One would never know that from current events, however. Utility management treats transmission as an inconvenient stepchild.

Locational marginal pricing, even if "complex," is well worth the benefits.

In two recent issues, PUBLIC UTILITIES FORTNIGHTLY featured editorials %n1%n on restructuring of the PJM Pool. Those two articles described proposals by the so-called supporting companies, %n2%n seven members of the Pennsylvania-New Jersey-Maryland Interconnection, to use a "locational marginal pricing" model for congestion pricing for electric transmission and to continue PJM as a "tight" power pool.

Divide the grid by usage (em local vs. regional. Apportion costs accordingly, to energy customers by fixed charge, and power producers by flow and distance.

Traditionally, utilities have received transmission costs through an average, rolled-in access fee, or postage-stamp approach. In a deregulated environment, that approach will lead to distorted pricing.

And not just because of transmission-line congestion.

Much of the current debate over electric transmission pricing has centered on the various competing methods of congestion pricing, such as zonal vs.

I sincerely appreciate your covering NARUC and its outlook in the July 15, 1997, issue of PUBLIC UTILITIES FORTNIGHTLY (p. 26). I believe your summarization of my conversation with your Associate Editor and his depiction of NARUC sends a clear message about the unmatched resources and capabilities our organization enjoys by virtue of its membership.
