SAIDI

Reconsidering Resource Adequacy, Part 1

Has the one-day-in-10-years criterion outlived its usefulness?

The one-day-in-10-years criterion might have lost its usefulness in today’s energy markets. The criterion is highly conservative when used in calculating reserve margins for reliability. Can the industry continue justifying the high cost of overbuilding?

Grid, Heal Thyself

Automation technologies promise a reliability revolution.

Utilities are using automation and back-office systems to improve their performance on outage management and service restoration. The next generation of smart-grid technologies promises a revolution in self-healing systems. But first the industry must gain confidence in the technology—and the business case for investment.

Regulatory Reform in Ontario

Successes, shortcomings and unfinished business.

A rebuttal to conclusions made in three Fortnightly articles that service quality declined in Ontario because of a performance-based regulation plan implementation.

Ontario's Failed Experiment (Part 2)

Service quality suffers under PBR framework.

Building upon last month’s installment, more is revealed on how, after 10 years of incentive regulation, reliability has declined in Ontario.

Ontario's Failed Experiment (Part 1)

Reliability declines after 10 years of incentive regulation.

After 10 years of incentive regulation, reliability has declined in Ontario. Regulators failed to enforce service-quality standards, and consumers are suffering as a result.

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.

Analyzing Asset Failures

Simulation modeling can improve O&M and capital-planning processes.

Electric utilities are faced with the challenge of managing a range of aging distribution assets that are critical to system reliability. They also are threatened with potentially huge costs as they seek to replace these assets over the coming years to maintain reliability. Making intelligent decisions about asset maintenance and replacement requires accurate information about the failure patterns of these assets over time.

Letters to the Editor

Taming the Wind is a pleasure to read. The article captures just about perfectly the value of forecasting in cost-effectively and reliably integrating wind power, of balancing in large markets, of geographical spread, and more. It also looks at what the future could hold.

Coming to America

U.S. utilities are gaining valuable lessons from technology developments abroad.

Structural and regulatory factors have allowed utilities in some countries to leapfrog America’s utility industry in terms of technology leadership. But U.S. utilities are learning valuable lessons from international advancements.

Reliability Now!

Tech experts weigh the options for improving power delivery.

We’ve heard it all before, but the issue isn’t going away: Reliability of power, from generation to distribution, remains a primary concern of the utility industry. But the current verdict is mixed, depending upon which experts you talk to. Aging equipment is a ticking time bomb—except when it isn’t. NERC CIP standards are driving reliability improvements—except when they aren’t. Maintenance is key—except where monitoring and automation are more important. And regulators should stand aside and let the market drive reliability improvements—but economic incentives wouldn’t hurt.
