The U.S. Supreme Court soon will issue a potentially far-reaching decision in a case involving Duke Energy Corp. What’s the upside for the electric industry?

The North American electric power grid has suffered several significant outages in recent years. These events and other incidents around the world spotlight the need for enforceable grid-reliability standards, wide-area visibility of the health of the power system, and real-time monitoring of grid-reliability performance to prevent blackouts. Effective reliability management requires real-time tools and technologies that can detect standards violations so that timely corrective or preventive actions can be taken.

Genuine price signals about the underlying cost of consumer energy usage are an important part of energy efficiency. With those signals, consumers can adapt to save high-cost energy, while making better use of available low-cost sources and supplies.

When I became the Consumers’ Counsel for the state of Ohio in April 2004, natural-gas prices were hovering between $7/Mcf and $8/Mcf (thousand cubic feet). In the next year and a half, Ohioans saw gas prices double, peaking at a residential statewide average of $16.89/Mcf in the month of September 2005. The latter reflects the exacerbation of prices, already high, by hurricanes Katrina and Rita in the gulf region. The purpose of this article is not to focus on the national security and energy independence issues that arise from these circumstances, but rather to examine what we can do in the United States to ensure affordable and reliable supplies for residential consumers in both the short and long term.

The time has come to start the transition from the current economic demand-response programs to demand response that arises naturally through market-based retail pricing.

Over the past few decades, utility sponsored conservation and load-management programs have helped thousands of customers better manage their energy costs. While these programs have helped lower overall electricity use, they generally have not provided an economic incentive for customers to reduce their consumption at specific times in response to wholesale electricity prices.

The “N-word” in the title first appeared in this journal more than 20 years ago, courtesy of the celebrated environmentalist Amory Lovins and his widely quoted piece, “Saving Gigabucks with Negawatts” (Fortnightly, 1985). Scroll forward a few decades. With restructuring of wholesale electric markets at FERC, plus formation of regional transmission organizations and independent system operators, the game was changed.

When FERC opened wholesale power markets to competition a decade ago in Order No. 888, it codified a system for awarding grid access known as the pro forma Open-Access Transmission Tariff (OATT), founded on physical rights, and on the fiction that electrons travel along a “contract path.” Should the commission “tinker” with the OATT, making only surgical changes to make it current? Or, do events instead warrant a complete overhaul?

Improving the day-ahead weather and load forecast by just 1 degree Fahrenheit would have huge financial benefits for the industry.

Distributed Generation

In the first of three articles, experts at Oak Ridge National Laboratory examine the technical obstacles, deployment, and economic issues surrounding distributed generation.

The existing electric power delivery system is a critical part of this country's economic and societal infrastructure, and proposals to increase the role of distributed energy resources (DER) within this system are welcomed by few in the utility industry.
