Rethinking Asset Values in a Competitive Environment

Power plants can bid on more than one product. That's why most spark-spread studies miss the mark.

Forward energy prices can make it look easy to place a value on a power plant. Yet something is missing. Plants can sell more than one product. One price may be up while another is down. As Einstein said, a theory should be as simple as possible, but no simpler.

That is why it is worth reexamining the methods commonly used to calculate forward price curves and estimate the expected revenues and profits of generating assets.

Distribution Utilities: Forgotten Orphans of Electric Restructuring

The "duty to connect" demands definition - such as the optimal investment in local wires, and who should pay for it.

As the electric utility industry continues its slow but inexorable transformation into a more "competitive" industry, there has been a notable absence of discussion concerning continued regulation of local distribution utilities, or discos.

Keys for Success in Power Plant Investing

It's not as straightforward as it seems, says an industry veteran.

No one can foresee with a high degree of certainty how electric energy markets will be structured over the long-term. The changes facing the electric energy industry may be as profound as those upheavals we've seen in the airline industry during the past two decades. In the "good old days," a flight from New York to Chicago had one price and an electric generating plant had a regulated price for each kilowatt-hour produced.

Price Forecasting in Spot Markets: Hidden Risks in Single-Part Bidding

The California Power Exchange doesn't solicit separate bids for plant start-up, spinning reserve or base load operation. That can make spark spreads a bit misleading

IT SHOULD COME AS NO SURPRICE THAT THE PROSPECT OF electric competition has created a huge demand for price forecasting services. To their credit, the forecasters have obliged, supplying an abundance of tools and techniques. Do the forecasts serve the needs of those who would use them?

Some might wish to use a price forecast to assign a value to assets.

Energy Storage: It's Not Just Load Leveling Anymore

ACCORDING TO ONE RECENT SURVEY, MORE THAN HALF THE U.S. population now lives in states with customer choice. Moreover, industry executives expect 20 to 50 percent of these customers to choose a new electricity supplier by year end. %n1%n

With changes expected in the way electricity is generated, delivered and sold, exerting pressure on prices, what does the future hold for energy storage technologies?

After all, restructuring efforts appear most active in the highest-cost states -- those with average electricity prices running above 7 cents per kilowatt-hour.

The New England Auction: Regional Strategy for Competitive Generation

USGEN IS THE NATURAL CANDIDATE TO PURCHASE NEES' generation assets. We have a well-established commitment to the region; we have strong power plant operating experience; and we have been a leader in promoting competition and customer choice in gas and electric industries."

(em USGen President and CEO Joseph P. Kearney

In August 1997, U.S. Generating Co., an affiliate of PG&E Corp., successfully bid $1.59 billion in a competitive auction for all of New England Electric System's non-nuclear generating business (18 power plants, plus power purchase contracts and other assets).

California's Scheduling Coordinator: Market-Maker with Advantage

AFTER A FOUR-YEAR DEBATE ON ELECTRICITY REFORM, CALIfornia's powerful industry players have carved out a unique and broad new role for "scheduling coordinators." SCs have the central role in offering fully unbundled generation, transmission and retail-access services. But could these SCs, by controlling the market, also become the new monopolists?

California's highly complex scheme for markets, while said to be laissez faire, maintains several artificial constraints and market protocols that create advantages for SCs.

Dynamic Scheduling: The Forgotten Issue

But not for long (em as power producers and

customers get more creative in matching plants with loads Dynamic scheduling is a "sleeper" issue in the move toward electric competition. Industry players are debating independent system operators. They are focusing on issues of governance and the form of transmission pricing. Consequently, they are ignoring critical issues concerning ancillary services. These services are not receiving the attention they deserve.

On Monday, January 6, the Board of Trustees of the North American Electric Reliability Council (NERC) voted unanimously to require mandatory compliance from its regional and affiliate councils with all reliability "policies" adopted by NERC. Previously, the regional councils (MAPP, ERCOT, ECAR, etc.) were only required to give their "best efforts" to comply.

As the board explains, "Compliance with NERC rules needs to be insured, but peer pressure will not be sufficient."

This new vote stems from "A Call to Action," mailed out on October 28 by Richard J.

Labor Day found me trudging around in one of those "big box" discount stores, looking for a sale on a new refrigerator. Out West, California lawmakers spent the holiday putting together their own discount plan (em this one promising rate cuts for the state's residential electric consumers, funded by "rate reduction bonds" backed by a state-owned bank for economic development.

Either way you cut it, the holiday proved worthy of its name.
