Evaluating Power Plant Property Taxes Under Deregulation

THREE FACTORS (em RESTRUCTURING, TECHNOLOGY AND environmental controls (em now create both reason and opportunity for electric utilities to lower their property taxes, which often make up a substantial cost of doing business.

Property tax valuation is fairly straightforward. Most states compute property taxes on fair market value, or what a hypothetical buyer and seller would agree the property is worth, with both parties having knowledge of the relevant facts and neither compelled to buy or sell.

AS YOU CHILL OUT IN YOUR TV CHAIR, WATCHING THE Winter Olympics from Nagano, Japan, think a moment about Kyoto, not far away, and what the climate change treaty might have in store.

On Jan. 8, federal climatologist Tom Karl announced that 1997 was the warmest year on record, with thermometer readings exceeding the mean (1961-90) by 0.42 degrees centigrade (0.75 degrees Fahrenheit). Writing in his World Climate Report, editor Patrick J. Michaels took Karl to task for reporting only half the story.

Looking Back on SO2 Trading: What's Good for the Environment Is Good for the Market

The overwhelming impression is one of growth (em in volume and in the number of participants.

The early 1990s was an anxious period for advocates of emissions trading. Concerns about whether the sulfur dioxide allowance market would ever develop tempered the heady success of the first national emissions trading program implemented by the Environmental Protection Agency under the Clean Air Act Amendments of 1990, Title IV. These concerns were heightened when in May 1992, Wisconsin Power & Light traded 10,000 allowances to the Tennessee Valley Authority.

Carbon Sequestration: Robin Hoods of the Forest?

Appearing as tree huggers, utilities draw skeptical reaction from environmentalists.

At first glance, it looks like the same old story: Environmentalists versus utilities. But this time, the utilities are the ones fighting for the forests (em with a twist.

Utilities, major producers of carbon dioxide, believe they've found a cost-effective way to offset emissions through carbon sequestration, or sinks, which means converting pastures to forests or maintaining old-growth groves.

But environmentalists call it an easy way out.

Climate Change at the Stack: Posturing Toward Kyoto

U.S., rest of the world ponder CO2 emissions, with utilities caught in the middle.

Four months from now, in Kyoto, Japan, international policy negotiators will decide how quickly to curtail carbon dioxide emissions and allay the world's fears of melting ice caps and rising temperatures.

The amendments to the United Nations Framework Convention on Climate Change, or FCCC, are likely to be founded more on world and domestic politics than on science. Industry climatologists, after all, insist the atmosphere is not warming as fast as others predict, and could be, in fact, cooling.

Electric vs. Gas Cont...

Mr. Lindsay's March 1 letter (PUBLIC UTILITIES FORTNIGHTLY, p. 6) requires some further discussion. We do agree that reducing cooling seasonal peak electric demand is desirable. Lessening the electric infrastructure's environmental effects and electric system failures, as we witnessed in the summer of 1996, is to the public good. However, thermal storage systems have siting issues and the potential to run out of capacity at the worst possible time on peak days.

Gas-fired Generation: Can Renewable Energy Reduce Fuel Risk?

Some in Congress would link customer choice with a portfolio standard. How would that play in a wholesale power market where gas turbines rule the roost?

WHAT KINDS OF POWER PLANTS WILL

get built in a deregulated electric industry? If recent history offers any guide, utilities and independent power companies will succumb to the traditional wisdom and invest in gas-fired combustion turbines and combined-cycle plants. Sound reasons may exist for doing so. The plants are less expensive than conventional steam plants. They put less capital at risk.

Minnesota Identifies Environmental Adders

The Minnesota Public Utilities Commission has adopted a schedule of environmental costs for electric utilities evaluating and selecting resource options in all commission proceedings including resource-plan and certificate-of-need cases.

In each such case the utilities will be required to provide three cost analyses for each generation-option provided: one using the values at the low end of the range (see table), one using values at the high end of the range, and one reflecting "direct costs only" (i.e., using zero environmental externalities values).
