The province’s renewable program was vastly oversubscribed. But was it successful?

Pumped-storage technology allows utilities to defer the time value of energy, but project developers have struggled to make their economics work. Increased demand for ancillary services and standby capacity might make pumped storage more viable.

Money may be difficult to come by for Wall Street financiers in these dark days, but apparently not for electric transmission construction—at least so far. A rash of recent orders from FERC shows that generous financial incentives remain available to companies seeking to expand the nation’s grid capacity.

Mandatory renewable portfolio standards are becoming the norm. But after low-hanging green fruits are harvested, renewable power might get scarce. Many utilities will struggle to meet RPS requirements until lawmakers create stable federal policies and a national market for green credits.

Electric utilities throughout the country are rolling out an assortment of mobile workforce solutions, many of which already are found in other industries. Three mobile workforce solutions recently were implemented at National Grid in Long Island, New York, FirstEnergy in Akron, Ohio, and Idaho Power in Boise, Idaho. Each demonstrates the state of the art in a different slice of the operations pie: power generation, distribution system operations, and customer service.

The prolonged period of capped rates in Pennsylvania—years longer than in any other state—has produced some benefits and some drawbacks. On the plus side, due largely to the rate caps, electricity costs in the Commonwealth have fallen from 15 percent above the national average in 1996 to below the national average in 2007. This has been a significant benefit, but a temporary one that many have taken for granted.

Photovoltaic technologies are beginning to appear more attractive than concentrated solar thermal plants. PV’s competitiveness is improving from technical and operational advancements, as well as significant commitments made by such utilities as Southern California Edison. In the long run, distributed central PV plants likely will gain a strong market position.

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.

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.

(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.
