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.

Letters to the Editor

Commissioner Rick Morgan of the Public Service Commission for the District of Columbia based his article, “Rethinking ‘Dumb’ Rates”, on the faulty premise that there is a consensus, either in the regulatory community or electric industry, or both, trending toward the immediate adoption of smart meters and dynamic rates and, worse yet, that such change should be embraced now just ‘cause it is today’s pretty amazing new stuff.

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.

Memo to the President-Elect (Part 2)

A clear and present need for nuclear energy expansion.

Addressing climate change will require extending the life of today’s nuclear fleet and laying the foundation for new plants.

2008 Regulators Forum: Putting Efficiency First

New rate structures prioritize conservation, but will customers buy it?

As saving energy becomes a policy priority, utility commissioners struggle to reconcile traditional revenue models with smart metering and smart pricing. Unlocking conservation potential will depend on transforming passive ratepayers into smart consumers. Fortnightly hosts a roundtable discussion with commissioners from six states.

Capital Conundrum

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.

Biofuel Furor

Will power plants get caught in ethanol’s food fight?

The debate over food vs. fuel never has been louder. Using corn to make the biofuel ethanol is perhaps the best known point of argument. Everyone is asking: Should the United States require a certain percentage of U.S. corn crops be turned into fuel in the face of global food shortages and exorbitant food prices? And what are the effects of diverting food croplands into producing fuel?

Revisiting the Keystone State

Rate caps have squelched competition in Pennsylvania.

The prolonged period of capped rates in Pennsylvania—years longer than in any other state—has produced some benefits and some drawbacks. On the plus side, due largely to the rate caps, electricity costs in the Commonwealth have fallen from 15 percent above the national average in 1996 to below the national average in 2007. This has been a significant benefit, but a temporary one that many have taken for granted.
