Rate Case Analytics

Hard numbers support operating- and capital-cost claims for gen plants.

It’s been a long time since many electric utilities have had to ask their rate commissions for the amounts of money they’re asking for today. States with deregulation programs either have frozen rates or reduced them over the last decade, in the hopes that competition would naturally lower prices to consumers. Now those programs are ending and their success is questionable. Utilities in more regulated states haven’t faced since the 1970s new build programs like the ones currently contemplated.

Smart-Grid Analytics

Intelligent networks support better decision making.

Sophocles once said, “Quick decisions are unsafe decisions.” Apparently Sophocles did not work in the utility industry. Utilities must make quick decisions every day to maintain a safe and reliable grid. As they have learned, the key to a quick and safe decision is making a well-informed decision. Yet utilities face challenges in providing enough information for their employees and automated systems to make these types of decisions.

Solve the Seams

The big challenge facing the Northeast energy markets.

The Northeast energy markets are working hard to establish new levels of regional coordination and cooperation. The region’s concerted effort is essential to resolving some of the industry’s toughest issues since the individual markets evolved. These issues include the elimination, reduction, or bridging of seams issues that prevent the economic transfer of capacity and energy between neighboring wholesale electricity markets, or control areas, as a result of incompatible market rules or designs.

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.

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.

A Day in the Life of Transmission Congestion

A forecast for California on Aug. 16, 2006

Transmission congestion affects both the cost and the efficiency of the power grid. Global Energy's Market Analytics LMP along with PowerWorld Corp.'s OPF Simulator and Energy Visual's graphical interface solution provides a richly textured visual representation of Global Energy's forecast of transmission congestion in California for Aug. 16, 2006.

The ABCs of PBR

In the alphabet soup of regulatory acronyms, performance-based ratemaking (PBR) may help shape events well into the next century. At present, PBR is being implemented, or considered by, public utility commissions (PUCs) in over 20 states. By 2000, PBR is likely to reach most of the 50 states as well as the Federal Energy Regulatory Commission. The pressures of a global economy have raised the stakes.
