(July 2011) Williams Partners L.P. expands Transco transmission lines; Google to provide fiber optic Internet service for Kansas City, Mo.; Constellation Energy picks Lynxspring Inc.; plus contracts and developments involving Servidyne, EnerNOC, Siemens Energy and others.

A century of electrification shows clearly that more electricity—and cheaper electricity—enhances public health, raises living standards and also improves the environment. Conversely, higher prices harm businesses and families, with a disproportionate impact on low-income households. Public welfare goals are best served by public policies that make electricity more accessible and affordable to the masses—not less.

In the wake of recent global-scale cyber intrusions, security concerns have expanded from being compliance and operational issues to fundamental risk management considerations. An integrated, enterprise-wide approach holds the greatest promise for securing critical utility infrastructure against increasing dangers in cyberspace.

Smart grid technologies bring a host of cyber security considerations that need to be addressed throughout the T&D domain—and even into the customer’s home. In this exclusive report, Department of Energy authors team up with industry experts to examine how to deal with the changes and challenges of securing the smart grid.

With a recent flurry of gas pipeline rate investigations at the Federal Energy Regulatory Commission (FERC), many pipeline owners face the prospect of having their profits scrutinized to ensure their rates are just and reasonable. Understanding FERC’s approach will help companies ensure they’re not falling outside the zone of reasonableness.

With large solar arrays and wind farms being proposed to connect to transmission and sub-transmission systems, are utility companies sufficiently prepared to handle the challenge of integrating these large intermittent resources? The industry now must decide whether transmission reliability factors — most notably dynamic voltage support and system frequency management — need to be resolved by renewable generators, or whether they should become a cost of doing business for transmission providers and reliability coordinators.

Electric vehicles promise major benefits for utilities, including increased electricity sales and accelerated transformation of passive energy consumers into collaborative stakeholders. But EV integration faces major challenges, from transformer overloading to the complexity of managing mobile transactions. Addressing these challenges in a collaborative way will allow the industry—and the country—to realize the benefits of a healthy market for electric transportation services.

(May 2011) Florida Power & Light unveils hybrid solar power plant; SECO selects Sensus for smart grid technology; Lockheed to implement Con Edison energy efficiency programs; Elster partners with SAIC to deliver comprehensive smart grid solutions; Columbia Power Technologies deploys wavepower prototype system; plus contracts and announcements from GE, Siemens, Verizon Wireless, DT, Xcel, Tenaska Solar and others.

The remedy for America’s gravest economic woes may lie in a smart grid that can deliver vast amounts of clean, renewable energy while enhancing our energy security and democratizing our energy system. Although regulatory questions and technical challenges might dominate the industry’s short-term focus, the smart grid’s driving forces parallel America’s long-term national interests — a fact that should guide ongoing technology strategies and investment decisions.

In the aftermath of the March 11 earthquake and tsunami, questions are arising about the safety and survivability of reactors located in geologically active areas. Major changes might be required, and as a result the U.S. nuclear industry might face an existential challenge on the order of the Three Mile Island accident.
