A tale of two energy worlds.
As federal policy makers push for GHG regulation and transparent markets, the California experience shows what works and what doesn’t work.
How much efficiency do ratepayers need—and utilities want?
When the applause dies down, the smart grid may turn out to be its own worst enemy. The California Independent System Operator (CAISO) explained this irony in comments it filed in May, after the FERC asked the industry for policy ideas on the smart grid.
How solar PV could redraw the map for green energy and grid investment.
When Pacific Gas & Electric broke the news six weeks ago that it had signed a deal with Solaren Corp. to buy 200 MW of solar energy from satellites launched into geosynchronous orbit, the idea seemed almost laughable. Solaren’s plan is to catch unobstructed sunlight falling on arrays of photovoltaic solar panels deployed in the crystalline void of outer space, and then to convert the generated electricity into radio-frequency energy for transmission to Solaren’s ground-based receiving station outside Fresno. Welcome to the new renewable reality.
New business models make energy storage attractive.
Utilities are leaving no stone unturned in their search for ways to save electricity. Federal incentives will support new technologies and projects, but can those incentives overcome structural barriers that stand in the way of major efficiency improvements? editors explore challenges and opportunities arising from the new efficiency mandate.
How to account for lack of strong price signals. A hard year puts deregulation to the test.
Catherine McDonough and Robert Kraus
The greatest benefits of time-of-use pricing come from avoided costs of peaking power and T&D capacity—but only if hourly retail prices accurately model the true costs of delivered energy, including scarcity rents. Restoring the missing price signals will encourage economic investments in AMI, conservation and system capacity.
(Octover 2008) Xcel Energy named David Sparby president and CEO of Northern States Power Minnesota. Entergy Corp. appointed Terence Burke general counsel and chief legal officer for EquaGen, the joint venture operating company to be owned 50 percent by Entergy and 50 percent by Enexus Energy. Steven Agresta was named executive vice president, general counsel and chief legal officer for Enexus Energy. NorthWestern Energy appointed Robert C. Rowe as president and CEO. And others...
The Big Build will test the industry’s access to Wall Street.
The era of easily available, affordable energy rapidly is ending and our society is realizing that our energy infrastructure is severely inadequate to supply the energy demands of the future. The major issue facing the sector today is how to fund and deliver this new climate-friendly infrastructure, which is currently estimated will cost almost $2 trillion between now and 2030.
Distributed solar modules are gaining ground on concentrated solar thermal plants.
Jonathan Lesser and Nicolas Puga
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.
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.
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.
