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.

Finding the 'Sweet Spot'

As president and CEO of ISO New England, Gordon van Welie has his feet planted firmly on each of two sides of a cultural divide. First, as a transmission system operator, van Welie must keep the lights on and the wires humming. At the same time, he must run a regional market—an ongoing experiment in freewheeling capitalism in an industry fraught with more long-term uncertainty than perhaps any other.

Letters to the Editor

In light of your prescient Frontlines column, “PURPA Redirected” (February 2008), I am curious of your insight. Is there a nexus between §571 of EISA and the demand response (DR) text in the pending FERC NOPR, RM07-19-000, “Wholesale Competition in Regions with Organized Electric Markets,” issued Feb. 22, 2008?
