AMI/Demand Response: For Real This Time?

Smart metering is coming of age. Is the utility world ready for it?

Some states, including Illinois, Oregon, Pennsylvania, and Texas, have been considering smart-metering questions as part of rate cases and resource-planning discussions. Other states, such as Kentucky, Louisiana, Ohio, and Virginia, have initiated EPACT Section 1252 inquiries separately from other proceedings. The tenor of the discussion also varies from state to state, with high-cost power states generally more attracted to AMI than low-cost states are.

Watching and Waiting: A Blueprint for Transformer Maintenance

How online monitoring can prevent costly failures.

The march of technology, the urgent call for greater grid investment, and a painful recent past have caught up with the utilities industry. One key area of preventative maintenance for utilities is the transformer, many of which are decades old. Representing approximately $200 billion in investment, these units—which currently number approximately 100,000—can’t be replaced overnight.

Mending Our Broken Capacity Markets

The ability to provide reliable capacity is becoming both riskier and more costly to society and investors alike.

Hold the Champagne?

There is much to celebrate in the Energy Policy Act of 2005, but what will federal regulators do?

When we least expected it, the politicians finally were able to pull a multi-billion white rabbit out of their hat—enacting a comprehensive national energy law (Energy Policy Act of 2005) that will usher in extraordinary changes in the industry However, just how the new law really will affect the industry is the question of the hour, with many provisions of the law left to the interpretation of regulators.

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.

RPS: Should States Get Credit?

The risks in renewable portfolio standards.

State-mandated renewable portfolio standards are being adopted across the country to facilitate the development of renewable energy projects. Nineteen states have enacted renewable portfolio standards, but significant barriers remain to fulfill the potential of RPS. Will RPS actually result in a substantial amount of new project construction?

IT Roundtable: The Digitized Grid

Data gathering and controllability offer the quickest path to reliability.

Technology leaders at Pacific Northwest National Laboratory, the Electric Power Research Institute, and the National Rural Telecommunications Cooperative present their visions of energy IT in the 21st century.

Cross-Subsidies: Getting the Signals Right

Should regulators care about the inefficiencies?

Utilities were founded to create cross-subsidies, but regulators need to address lingering uncertainties about such subsidies in a coherent, constructive way. The authors offer five recommendations.

Renewable Energy

Mandatory portfolio standards have different implications for different technologies.

Renewable Energy:

Mandatory portfolio standards have different implications for different technologies.

The federal government and several state governments are considering programs to increase the share of electricity produced by renewable generation resources to 20 percent or more. If these programs are implemented and pursued successfully, they will trigger a dramatic change in the role of renewable generation and the requirements placed upon it by the market.

Profiting from Transmission Investment

A holistic, new approach to cost/benefit analysis.

A holistic, new approach to cost/benefit analysis.

The still-fresh memories of last year's Northeast blackout coupled with rising congestion nationwide have increased awareness of the electric transmission investment shortfall in the United States. Such investment, in the right locations, would have a highly positive benefit-cost ratio. But how much should be spent?
