Negawatt Pricing

Economists take sides in the battle for DR’s soul.

Back when the U.S. economy and power consumption still were bubbling, PJM reported in August 2006 that customer curtailments during a week-long August heat wave had generated more than $650 million in market-wide energy savings—all at a mere $5 million cost, as measured in direct payments made to the demand response (DR) providers, set according to wholesale power prices prevailing at the time. Where else but the lottery can you get an instant payoff of 130-1?

3Rs for Power And Demand

Dynamic monitoring and decision systems maximize energy resources.

The operations and planning rules for integrating variable resources aren’t the same across the electric power industry in the United States at present. Opinions are somewhat divided about what these should be, as well as the assessments of potential benefits and costs. In order to support sustainable deployment of variable resources at value, it’s critical to identify major sources of potential problems and to proactively design and implement a systematic framework for managing their unique characteristics as reliably and efficiently as possible.

Nuclear Standoff

Can climate-policy brinksmanship create a sustainable nuclear industry?

American voters dashed the nuclear industry’s hopes for a renaissance last November—or so it seemed. Recent developments in Washington have rekindled those hopes, but will climate-policy brinksmanship lead to a sustainable future for nuclear power?

Carbon Solutions

Capture and storage tech developments secure coal’s future.

Capture and sequestration will help ensure the future of coal-fired power plants. Demonstration projects are allowing utilities to kick the tires on the latest technologies, and to learn how CCS will affect operations and economics at state-of-the-art plants.
