Unpredictable periods of operation are one of the disadvantages of wind and solar technologies. If there were an economic means of storing the energy from the time of production to the time of demand, the value of renewable energy sources would greatly increase. Here are some ideas for how to bridge that gap.

CSP Giants Form Alliance. Concentrating solar power companies Abengoa, BrightSource Energy, and Torresol Energy in early March formed the Concentrating Solar Power Alliance, an organization dedicated to educating U.S. regulators, utilities, and grid operators about the unique benefits of concentrating solar power (CSP) and of thermal energy storage. The U.S. has more than 500 MW […]

Planning for resource adequacy—something that was relatively simple in the context of vertically integrated utilities—continues to be a difficult issue in competitive electricity markets. Whereas state public utility commissions used to have exclusive authority to determine what generation needed to be built and when it was to be available, this responsibility has been assumed by RTO/ISOs in regions with competitive markets. Each region approaches resource planning differently, and each region faces unique problems.

Several new models of plug-in electric vehicles will enter the market in 2012, joining the Nissan LEAF and Chevrolet Volt. The Edison Electric Institute has prepared four suggestions to help utilities smoothly handle the introduction of these vehicles to roads and grids.

Progress Energy has adopted an emergency worker callout program that has eliminated manual dialing, improved work acceptance rates, and increased the speed of worker reporting. The standardized process also complies with union work rules that require equality in overtime opportunities, by seniority. The business case for automating the worker callout process is compelling.

A year has passed since Japan’s Fukushima Daiichi nuclear plant was destroyed by earthquake and tsunami. What is the economic price Japan must pay?

Chinese state entity State Grid Corp. of China (SGCC) and battery maker BYD in January said they had finished construction on what they call “the world’s largest battery energy storage station”—a project in Zhangbei, Hebei Province that combines 100 MW of wind and 40 MW of solar capacity, a smart power transmission system, and 36 MWh of energy storage in arrays “larger than a football field.”

Putting more money and effort into information and information technology will pay solid returns when it comes to understanding and adapting to the world around us, including our changing climate.

A new project planned by RWE and partners Nexans, the Karlsruhe Institute for Technology (KIT), and Jülich is poised to mark another milestone for high-temperature superconductor (HTS) cable technology, which transports electricity without losses when cooled down to about –200C (–392F).
