Green Energy Outlook

Realizing the benefits of a modernized system requires an integrated strategy.

The U.S. power market consistently has displayed cyclical characteristics of boom and bust over the last two decades. Today’s market environment has been directly and significantly impacted by the recent economic recession. Decreases in load growth, declining commodity prices, and lack of accessible financing have caused challenges for the industry.

Wellinghoff's War

FERC fights for the green-grid superhighway—even if Congress won’t.

The Senate’s deadlock over carbon cap-and-trade legislation has not deterred FERC Chairman Jon Wellinghoff from an agenda bent on promoting renewable energy and fighting climate change. Last fall, even as Congress dithered, FERC launched a landmark initiative that likely will lead to sweeping new rules for expanding the nation’s electric transmission grid, grounded on Wellinghoff’s belief in wind, solar, and green power resources.

Can We Afford Climate Regulation?

Lawmakers are rushing a costly decision.

Utilities are struggling to predict the costs of greenhouse gas regulation. In the quest for a greener planet, how much should consumers be asked to pay for environmental benefits that might be difficult to measure?

Carbon In Electricity Markets

Price transparency will drive GHG reductions.

In light of coming GHG legislation, price transparency is the key to achieving cleaner generation through the dispatch of lower-carbon sources.

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.

Fingerprinting the Invisible Hands

Opaque markets inflate power prices.

Secrecy is the norm in electric power bidding. This lack of transparency impedes an efficient electricity market. Bringing daylight to power markets would reduce prices and save consumers money.

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.

Redefining PV Capacity

Effective metrics give solar its due credit.

Photovoltaic (PV) power generation is an intermittent, non-dispatchable resource generally considered as energy-only with no capacity credit. However, there is ample evidence that solar energy reliably is available at peak demand time when loads are driven by day-time commercial air conditioning, and can contribute effectively to increasing the capacity available on a regional grid.

Green Price Stability

New approaches account for the economic benefits of renewables.

Many green power customers benefit from long-term fixed prices. The most effective programs recognize the value of this price hedge—and fairly exempt customers from fuel cost adders in utility rates.

Dynamic Pricing Solutions

How to account for lack of strong price signals. A hard year puts deregulation to the test.

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.
