How a move to bring power markets to the Great Plains has uncovered a crisis in grid planning.
They call the United States the “Saudi Arabia of Wind.” That’s due in large part to the huge potential of the Great Plains. But there’s a hole in the metaphor. Wind power development in some parts of the prairie is falling short of expectations.
Plug-in hybrids usher a new era for wind power.
Plug-in hybrid vehicles (PHEVs) open a new intersection between wind power and transportation.
When Spanish utility giant Iberdrola announced last June that it would acquire Maine-based Energy East for $4.5 billion, it signaled a potential surge in major foreign owners buying into U.S. utility companies. Fortnightly spoke with Pedro Azagra, director of corporate development for Iberdrola S.A. in Bilbao, Spain, to get an update on the acquisition, and his impression of U.S. merger-approval processes.
Voltage sag shows value of accurate wind forecasting.
Variability is a well-known characteristic of windpower, and system operators know they must plan for changes in wind generation over the course of a day. But when those plans fall short, voltage levels can drop quickly, forcing grid operators to dispatch resources to make up the difference—either by shedding load or bringing reserve generation online.
ERCOT’s February emergency suggests storage capacity is needed to support renewables.
ERCOT in February averted a blackout that could have become a disastrous defining moment for the windpower industry. This near miss can teach utilities and system operators valuable lessons about integrating variable energy sources into the power grid.
Wind deals promise brisk business for years to come.
(May 2008) Senators were voting on legislation to extend the renewable production tax credit (PTC) as this issue of Fortnightly went to press. But with federal tax support for windpower in a perennial state of limbo, is the current rate of growth sustainable? To find out, Fortnightly spoke with Andrew Redinger, managing director and head of the utility and alternative energy group at KeyBanc Capital Markets.
Utilities can transform the world’s energy economy.

Perceval’s sagas are largely forgotten today, but at least one of them serves as a useful metaphor for an industry seeking the proverbial Holy Grail of clean-energy technology—specifically, the tale of Perceval and the Fisher King.
Modern approaches to system operations and forecasting make the most of variable energy sources.
Nobody disputes windpower’s variability; that’s a given. But modern approaches to demand management, grid integration and wind forecasting are making windpower more predictable and grid friendly. And technology companies are marketing a variety of equipment and services to support a growing base of variable wind capacity—sort of like a virtual Country Kitchen Buffet for the windpower picnic.
The spotlight is on. But true stardom will require more direction from utilities.

Wind has become today’s hit—a potential blockbuster, even—but still needing that one big break. To make it big, utilities will have to lead the charge as owners. That will force utilities to consider and evaluate the significant credit implications that can arise when signing a power purchase agreement with developers that lack deep pockets, or implement fly- by-night schemes.
New technologies are helping windpower mature as a viable power supply choice for utilities.
Few people understand how to ride shifting winds better than Jim Dehlsen does. Dehlsen founded Zond Energy Systems 25 years ago, and steered the company through a series of major changes and challenges—the oil-price collapse of the 1980s; ambivalent energy policies, with on-again, off-again production tax credits; and the sale of controlling interests in Zond to Enron in the late 1990s. Should it come as any surprise, then, that Dehlsen still is bullish on windpower’s prospects?
