Smart Grid

This spring, Xcel Energy, along with state and technology partners, is set to test what the utility says is the first battery capable of storing wind energy. The ability to store energy from renewable generation sources with variable output is key to maximizing the value of renewable power in general and to Xcel’s “smart grid” plans in particular.

Demand response and advanced metering programs have made significant progress in serving more consumers across the country, says a new Federal Energy Regulatory Commission (FERC) report that charts the expansion of these energy-saving programs since 2006.

An integrated matrix of 10 high-power flywheels built and tested by Beacon Power Corp. earlier this year successfully absorbed and supplied a full megawatt of electricity, the energy storage technology company said in September. The achievement could mean that grid regulation using efficient energy storage is close to commercial deployment. The flywheel system, called the […]

Last month, POWER explored the growing importance of the smart grid, which is envisioned as using digital technologies to enable integrated, real-time control of all the system’s elements, from generation to end use. This month we focus on the emerging technology of microgrids: controlled groupings of dispersed generation sources that are connected to the main electrical grid but that can function independent of it. We examine their benefits and their potential impact on 21st-century utilities and their customers.

The next-generation power grid—enhanced by digital technologies throughout the network to give generators, distributors, and customers greater control—promises to improve efficiency and lower operating costs. This year, in the most full-scale effort yet, Xcel Energy begins introducing intelligent grid technologies that it hopes will make Boulder, Colo., the first Smart Grid City.

In mid-2006, a Google search of the term “Smart Grid” generated around 2,000 responses. The same search this past month yielded more than 500,000 hits from a wide variety of sources. The explosiveness of the concept is especially interesting because there is no universal agreement on what constitutes a smart grid—much less agreement on what […]

  North America’s electricity grid has been described as the world’s most complex machine. The grid is unique among utility infrastructure systems for its need to have supply and demand—generation and load—balanced at all times. There still are no technologies for storing large quantities of electricity akin to liquefied natural gas tanks, voice mail, or […]

The advent of the Smart Grid will bring a new driver for value creation to the electric power industry: economies of connection. In the future, the Smart Grid may offer our industry improved returns more typical of Internet-based businesses like eBay, Amazon, and Google to replace the diminishing returns typical of traditional “steel in the […]

Managing ongoing threats to power plants’ digital, telecommunications, monitoring, control, and automation systems is no longer just a good idea. It’s an essential element of superior plant operations and now a regulatory requirement as well, thanks to new critical infrastructure protection standards recently approved by FERC.

T&D systems with embedded intelligence have a great future, and they always will. Too many powerful forces—politics, money, and power—remain to be reconciled before consumers and utilities can work together, seamlessly, to reduce electricity demand and eliminate delivery system bottlenecks.
