The Smart-Enough Grid

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.

Renewable Reality Check

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.

Carbon and the Constitution

State GHG policies confront federal roadblocks.

So far, states have taken the lead in carbon-control strategies. These state actions, however, could lead to constitutional conflicts—as recent court battles demonstrate. Only the U.S. Congress can regulate interstate trade, so states must step carefully in controlling carbon leakage.

Stabilizing California's Demand

The real reasons behind the state’s energy savings.

In 2006, the California legislature and governor positioned energy conservation and efficiency as the cornerstone of the state’s Global Warming Solutions Act. The Act mandates a 2020 statewide limit on greenhouse gas (GHG) emissions to 1990 levels. Compliance will be nothing short of Herculean: California will have to reduce per capita energy usage in a manner that accommodates continued brisk population growth and protects the state’s economy from economic dislocations and recessionary pressures.

Wooing the Western Wind

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.

Back to Gas

Utility turbines bridge the capacity gap.

Utilities are turning to natural gas as a bridge fuel, and to support non-dispatchable renewables.

Transmission is Bubbling

A billion-dollar ‘gold rush’ could send grid rates through the roof.

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.

PV vs. Solar Thermal

Distributed solar modules are gaining ground on concentrated solar thermal plants.

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.

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.

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.
