Reliability Monitoring: The High-Tech Eye In the Sky

How reliability performance monitoring and standards compliance will be achieved in real time.

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.

Squeezing BTUs From Light Bulbs

Incandescent light bulbs create a cogeneration benefit by warming the indoor spaces they illuminate.

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.

A Consumer Advocate's View: Decoupling and Energy Efficiency

Two sides of the same coin.

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.

Special Section On Metering: Needed in New England: Stronger Market Connections, Savvier Electricity Usage

The region’s retail and wholesale electricity markets should be linked via dynamic pricing.

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.

Encore for Negawatts?

Congress renews PURPA’s call for conservation and load management, but the world has changed since the 1970s.

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.

Tariff Tinkering

FERC says it won’t ‘change’ the native-load preference, but don’t bet on it.

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?

Guessing Mother Nature's Next Move

What can be done to improve weather prediction and load forecasts?

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

Windpower: Beyond Boom and Bust

Windpower is caught in a vicious cycle of Washington politics. Escaping the cycle will require visionary leadership in Congress and the utility industry.

With the Production Tax Credit subject to the whims of a fickle Congress, U.S. windpower remains in an ongoing state of uncertainty. Will the United States embrace the technology?

Distributed Generation: Who Benefits?

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.
