Pilot projects are demonstrating the potential of smart metering and smart rates to make the most of supply and demand resources. But as empirical studies show, not all pricing designs are equally suited to every region.

(August 2009) When I hear the new buzz word term dynamic pricing I think of politicians who may be socialist or liberal, but who call themselves “progressive.” Now, what thoughtful person would not vote for a progressive. Do you want to vote for someone who isn’t progressive? That would make you some kind of Luddite. The same holds true for the people now running around the country calling for “dynamic pricing” i.e., charging $5/kWh for up to 100 hours per year, and calling any other form of pricing “dumb rates.”

Achieving the smart grid’s potential requires a revolution in electricity pricing. Smart metering and smart rates might yield surprising and beneficial changes in the U.S. utility industry. But capturing those benefits will require an intelligent and careful approach to implementing dynamic pricing.

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.

Consumers await the revolutionary interface that will allow them to control their energy consumption. Besides maximizing efficiency in the home, these units will allow more

price and product competition. But disincentives to innovation are making for slow progress.

Contrary to conventional wisdom, electricity demand isn’t immune to price elasticity, and rate designs can encourage conservation. In particular, inclining block rates coupled with dynamic pricing can cut electric use by as much as 20 percent.

When summer heat waves cause electric demand to peak, they also often cause wholesale electricity prices to rise substantially above their average levels. However, since most electricity customers face retail rates that do not reflect this movement in wholesale market prices, they do not modify their consumption patterns, causing a significant drop in economic efficiency. The Energy Policy Act of 2005 calls upon states and utilities to evaluate and implement DR programs to mitigate this problem.

Forget the mega merger as a means to acquire new power plants. FERC’s new rules may offer a better path.

Electric M&A:

The merger with PSE&G may herald a new industry structure, squarely at odds with regional markets.

Call it the merger that broke the bank.

The marriage between Exelon and PSEG, owner of the utility Public Service Electric & Gas (PSE&G), formally proposed in February in papers filed at the Federal Energy Regulatory Commission (FERC), would create the largest electric utility in the United States.
