MAINE YANKEE PRUDENCE. The Maine Public Utilities

Commission will investigate the prudence of Maine Yankee Atomic Power Co.'s decision to close its nuclear plant permanently.

The PUC said Oct. 22 that unrecovered investment in Maine Yankee combined with the loss in plant value could cause additional stranded assets for plant owners Central Maine Power Co., Bangor Hydro-Electric Co., and Maine Public Service Co. If imprudent action is found, the PUC said it would take steps to ensure that Maine's electric ratepayers do not bear any related costs.

Go figure. Plans to shut down nuclear generation in Ontario should not affect electricity supplies this winter within the United States, despite early rumors of chaos and rising natural gas prices. However, an unexpected slowdown in coal delivery by some U.S. railroads has "seriously reduced" on-site stockpiles of coal at some generating plants in three regional reliability councils - ERCOT, SERC and SPP - particularly those dependent on coal from the Powder River Basin in Wyoming.

AT HIS 21ST HEARING ON FEDERAL ELECTRIC Restructuring, Rep. Dan Schaefer (R-Colo.), chairman of the House Subcommittee on Energy and Power, said the two-day proceedings were the "beginning" of developing consensus on legislation.

Fellow subcommittee members spoke out on competitive issues at the Oct. 21 hearing, which highlighted their lack of consensus. The Clinton Administration was represented by the Department of Energy's Deputy Secretary, Elizabeth Moler, who said nothing about its restructuring plans.

WHO HAD THE BEST ANNUAL REPORT COVER in the utility industry in 1997? It's a tough choice. Several covers emerged from the masses of standard-issue, black-type-on-white (or off-white) backgrounds. Which leads us to Public Utilities Fortnightly's first annual report cover "award" for the best of in a variety of untraditional categories.

BY WHAT AUTHORITY CAN STATES FAVOR RENEWABLE

energy in a restructured electricity market?

Renewable resource funding marks a major point of contention in utility deregulation. Environmental groups fear that without some form of compulsion or subsidy, or both, renewable resources will not survive in an energy economy based on least direct consumer cost. However, utilities do not want to be saddled alone with the chore of carrying all renewables to market.

UNDER RETAIL COMPETITION, AT LEAST SOME electricity customers will make purchase decisions out of concern for the environment. A variety of utility green pricing programs already target environmentally concerned consumers. Recent experience in Massachusetts and New Hampshire confirms that utilities and power marketers are gearing up for full-fledged green power marketing to differentiate their products in a competitive environment.

WHOLESALE POWER PRICES DURING THE SUMMER OF 1997 REACHED LEVELS MUCH higher than in 1996 - higher than the variable fuel costs of even the costliest units (see Figures 1 and 2). This situation has confounded many observers. Many thought, in spite of forecasts to the contrary, that markets would continue to exhibit excess capacity for years to come. They thought need for new capacity was distant and that hourly markets would not see premiums in excess of fuel costs for marginal units - the so-called "pure" capacity premium - for years to come.

The evidence is in.

AS U.S. ELECTRICITY MARKETS BECOME increasingly competitive, large industrial customers will discover many new choices. These choices include the opportunity to modify the amount and timing of electricity use in response to prices that vary from hour to hour. In addition, customers can sell certain electricity services, including operating reserves and load following, to the system operator. And industrial customers with cogeneration facilities can participate fully in bulk power markets, buying and selling energy and ancillary services in response to changes in spot prices.

IS TEMPERATURE THE SINGLE MOST IMPORTANT FACTOR IN how gas storage is used? Or are other variables involved? Can we answer these questions - and verify the results?

Since FERC Order 636, natural gas storage has grown into a high-profile asset in the industry. As a result, the industry has responded by changing the way it uses this storage. The exact nature of this adjustment is not apparent at a glance; one must first analyze industry data.
