Fortnightly Magazine - May 2008

Carbon Transparency

Public companies face rising pressure to disclose climate-change risks.

Regulation of greenhouse-gas (GHG) emissions and other efforts to control these growing environmental concerns increasingly are impacting businesses, and investors are seeking more and better information on climate-change risks to make informed investment decisions.

Seeing Green

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.

The High Cost of "Free" Capacity

Fickle behavior by LSEs threatens to destabilize organized markets.

Dodging capacity payments might become an art form among load-serving entities and large electric consumers, as evidenced by Duquesne’s plan to exit PJM, as well as alternative market-designs proposed by large users. But such behaviors might only serve to disrupt organized markets and cause a return to full regulation.

No Generator Left Behind

A new theory on capacity markets and the missing money.

On Wednesday May 7, FERC will host a conference in Washington, D.C. that might prove extraordinary. The commission staff promises not only to review the forward capacity markets now operating in New England and PJM—each a story unto itself—but also to discuss a new rate-making theory that has come virtually out of nowhere and which proposes to help solve the notorious “missing money” problem.

Energy Technology: Cultivating Clean Tech

New Models for Energy RD&D: A new ‘Clean Energy Institute’ could lead the industry’s war on climate change.

Clean-energy R&D needs better funding and leadership to meet aggressive greenhouse-gas emissions reduction targets. But how does the industry get there, and what management model best suits achieving such lofty goals? A new ‘clean-energy institute’ might be the answer.

Optimizing Demand Response

A comprehensive DR business case quantifies a full range of concurrent benefits.

The benefits of DR remain difficult to quantify. Building a comprehensive business case requires a shift in how policy makers think about DR in order to understand its real possibilities.

Windpower's Warning

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.

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.

What Happened in ERCOT

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.

That’s exactly what happened in ERCOT on an evening in February, when a combination of events left the system operator short on power and long on demand (See Figure 1).

Green Heroes

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.
