Electric utilities nationwide are attempting to retreat from commitments to energy efficiency (em a retreat that will benefit few customers, while damaging many. This retreat is driven by fear of retail wheeling (em that consumers will be able to shop for the lowest prices among competing entities. In turn, the threat of retail wheeling has spurred utilities to a frantic scramble to cut costs and trim rates.

Until recently, both regulators and electric utilities have considered photovoltaic (PV) technology (i.e., solar cells) an unattractive
energy-supply option because of its relatively high cost. Now, however, a number of utilities have shown interest in using PV for peak-shaving.

Over the last decade, the Total Resource Cost
(TRC) test has become the dominant method of comparing the costs and benefits of demand-side management (DSM) programs. Yet the TRC test fails to recognize the negative rate impacts from reduced kilowatt-hour consumption. DSM advocates argue that more extensive DSM programs will compensate for this flaw. If all customers have an opportunity to participate in a DSM program, they claim, customers' total bills will fall in spite of rising rates that pay for the DSM investments.

As competition in the electric industry increases, so does utility concern about the effect of demand-side management (DSM) programs on electricity prices. Because DSM programs often raise prices, several utilities have recently reduced the scope of their DSM programs or focused these programs more on customer service and less on improving energy efficiency (see sidebar). Whether all utilities should follow suit is, however, open to question. We contend that DSM programs do not always exert upward pressure on prices (em just sometimes.

In setting utility conservation goals, the Florida Public Service Commission (PSC) has decided to permit the state's electric utilities to eliminate demand-side management (DSM) programs that increase rates for nonparticipating customers.
