Intelligent power grids present vexing cyber security problems
Michael T. Burr
In a world where streetlights can be used as a weapon, controlling local utility networks becomes more than just a matter of public convenience and necessity. It becomes a matter of public safety and even national security. And in that world, the idea of an inter-networked, automated distribution grid poses troubling questions about cybersecurity vulnerabilities.

Grid reliability depends on ‘reasonable business judgment’
Michael T. Burr, Editor-in-Chief
The word “security” no longer means what it used to mean. Now, “security” means gates, guards and guns. It means protecting critical assets with a multi-layered cyber and physical perimeter. It means exercising vigilance and caution, and accepting inconvenience as a matter of routine.
Before the hearings started, I felt the number of critical cyber assets for a medium size utility would be on the order of several thousand, not 20 as some major utilities are identifying under the CIP standards. This should be a red flag for the industry.
TXU’s buyout structure creates a potential model for utility M&A and refinancing deals
Terry A. Pratt
2007 was a big year for TXU Corp., as it went private in the largest leveraged buyout in history. To sweeten the deal for environmentalists and regulators, TXU made structural and financial concessions.

Financial-risk coverage is falling short in utility returns
Donald Murry, Ph.D. Zhen Zhu., Ph.D. and Michael Knapp, Ph. D.
When setting the allowed returns on common equity of jurisdictional utilities, state regulatory authorities apply the virtually universal standard that the allowed returns should be similar to returns on common equity investments in companies of equivalent risk. Such returns generally are accepted as fair if they are no higher than necessary and still sufficient to attract investment. Despite the universality of this regulatory standard, our investigation of recent allowed returns by state commissions shows that a key risk—financial risk—as measured by accepted, measurable metrics, has not been a factor affecting the level of allowed returns in the United States in recent years.

Credit-quality concerns join fuel and market factors to affect power-plant valuation
Devrim Albuz and Gary L. Hunt
Lenders know there are billions of dollars of weak financial assets in the market, such as securities backed by bad mortgages. The problem is no one knows who is exposed at what level to those weak financial assets. This causes a lack of confidence in the lending industry, and a credit crunch that — if unabated — could cause a recession.
