Demand-Side Dreams

FERC would relax price caps—sending rates skyward—to encourage customers to curtail loads.

About four months ago, at a conference at Stanford University’s Center for International Development, the economist and utility industry expert Frank Wolak turned heads with a not-so-new but very outrageous idea.

Unintended Consequences

Does anyone care about rising redispatch costs?

Regional transmission organizations (RTOs) or independent system operators (ISOs) dominate the major power grids of North America, with the notable exceptions of the Southeast and Pacific Northwest. The purpose of this article is not to criticize system reliability but to highlight the more pervasive challenge today and for the future: Controlling the cost impact of decisions by grid operators on energy market participants.

Electric & Hybrid Cars: New Load, or New Resource?

The industry must join a growing chorus in calling for new technology.

A growing movement to bring plug-in hybrid and all-electric cars to market has emerged, bolstered by the undeniable economic and national-security benefits that result from displacing gasoline with electricity. Also, our editor-at-large talks with Tesla Motors CEO Martin Eberhart.

The Nation's Grid Chiefs: On The Future of Markets

Exclusive interviews with the CEOs of five regional transmission systems.

AMI/Demand Response: Getting It Right the First Time

Each DR portfolio will have a different set of AMI needs, based on overall technology infrastructure.

Advanced metering infrastructure (AMI) evaluations will benefit greatly from creating an appropriate DR portfolio as part of the overall solution.

In the Energy Policy Act of 2005 (EPACT), Congress sent a strong message to electric utilities, consumers, and industry regulators that they need to get serious about advanced metering, time-based rates, and demand response (DR).

To underline this point, EPACT states:

Wholesale Competition: The Big-Bang Effect

Consider the opening of the PJM market, and its effect on prices.

Wholesale competition is working, and the best evidence to date is the savings produced from the opening of the PJM market to competitive power generation from the Midwest. A real-time case study unfolded before our eyes in May and October 2004.

Capacity Markets: A Bridge to Recovery?

A review of the ongoing evolution of market design.

While it appears that capacity markets are here to stay, there is little consensus regarding the best design. Markets in the United States are in a state of flux, with debate raging over many different capacity market pricing schemes. While the winning recipe has yet to be selected, it is likely that participants in certain markets will witness significant changes.

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.

An Expensive Experiment? RTO Dollars and Sense

Financial data raises doubts about whether deregulation benefits outweigh costs.

This year, U.S. electricity consumers will spend more than $1 billion financing the operation of six RTOs. RTO costs have nearly doubled since 2001. Restructuring the energy industry was more costly and more risky than anticipated, and reasonable estimates of RTO costs outweigh nearly all of the benefits anticipated.

Backed By Wind

The need for additional generation to compensate for wind variations is disappearing.

Utility-based studies have laid to rest the concern that a wind plant needs to be backed up with an equal amount of dispatchable generation. Even at moderate penetrations, ancillary services to back up new wind power need not be more than is required of a system as a whole.
