As I write this column at the beginning of spring, I have two kinds of spring fever: excitement about warming temperatures that bring spring flowers and the “hay fever” caused by tree pollens. I have mixed feelings about spring. I mention this only because the power industry is experiencing a spring fever of its own. […]

The digital economy has changed the way we shop for clothing, travel, communicate with friends and family, consume news, and watch television—among so many other things. But the innovative potential of the digital economy has not yet found a place within the electric system. With that important goal in mind, New York has embarked on […]

The wireless transmission of power by microwave over long distances is viable, Japanese technology firm Mitsubishi Heavy Industries (MHI) has proved in a recent ground demonstration test. The company has been developing the new technology for use in space solar power systems (SSPS)—which it says will be “the power generation systems of the future.” As […]

When many older plants were built, steel and cast iron piping were common materials used underground. Although these materials have proven to have long, useful lives, improvements in plastics offer additional alternatives today. An understanding of best practices for inspecting and servicing buried piping will help you keep systems operating as designed.  Most, if not […]

After adding a 280-MW geothermal power complex to its grid last year, Kenya is producing most of its power from geothermal sources, says the state-owned Kenya Electricity Generating Co. (KenGen). This February, the East African country formally inaugurated the last phase of the Olkaria geothermal power complex, which comprised the 140-MW Olkaria IV plant and […]

ALLETE Inc., a Minnesota holding company known mostly for its Minnesota Power subsidiary, is making a major strategic transition into the broader world of energy services, exemplified by its recent purchase of U.S. Water Services. At the same time, Minnesota Power, which previously transitioned from hydro to coal, now is shifting to a portfolio of […]

Europe—and especially Germany—has been struggling with how best to integrate large amounts of renewable generation while maintaining grid stability. While considerable attention has been devoted to expanding national transmission systems, new links between those national grids are growing in importance. The biggest project so far took a step forward when, on March 19, the consortium […]

Given the costs and other concerns about currently available technologies for capturing and storing carbon dioxide from fossil-fueled power plants, interest in new technologies remains high. Here’s a look at some potentially promising approaches that are advancing the technology frontier.  Frontiers represent the boundary between the known and the unknown. As researchers attempt to push […]

When it was erected in 1889 (seven years after POWER magazine was founded), the iconic iron-lattice Eiffel Tower was meant to serve as the entrance arch of the World’s Fair—and designed to stand only 20 years, about the lifetime of a wind tower. Some 126 years and several renovations later, the Paris landmark has evolved […]

Advocates for the continued reliance on coal for baseload electricity cheered late last year when North America’s largest power-related carbon capture and sequestration (CCS) facility was commissioned. Since then, that pool of advocates is evaporating as prominent electricity industry decision-makers publicly distance themselves from coal and champion alternatives for a low- or no-carbon future. If […]

NRC Advances Design Certification of Westinghouse SMR, South Korea’s APR1400. The Nuclear Regulatory Commission (NRC) on Feb. 27 approved Westinghouse Electric Co.’s testing approach for its small modular reactor (SMR) design—a “significant” step that the Toshiba Corp. company said will reduce the time ultimately needed to obtain design certification. By granting a safety evaluation report […]

How to give electricity customers who can’t take advantage of rooftop solar access to the sun? Community solar—a shared resource—is a fast-growing segment of the renewable energy market, making solar photovoltaic power more accessible while offering another approach to distributed generation. Mention “solar energy” and the image that probably comes to mind is an array […]

The Egypt Economic Development Conference (EEDC) in Sharm El-Sheikh resulted in some big agreements for the Egyptian government, including a reported $10.5 billion deal with Siemens and a $1.7 billion order with GE. The conference was held March 13–15, 2015, and was touted as a key milestone of the government’s medium-term economic development plan, which […]

In the UK, which has the world’s largest offshore wind capacity, in large part due to government backing, formal negotiations have begun on public funding of a £1 billion ($1.48 billion) tidal lagoon project to produce electricity from turbines in Swansea Bay, South Wales. The 320-MW project (Figure 3)—which could be the first of its […]

General Electric’s (GE’s) new flagship HA turbines, which will be the largest and most efficient in their class when deployed, will see their first delivery at EDF’s Bouchain combined cycle plant in France this summer. The first U.S. order is from Exelon for four 7HA turbines intended for expansions at the Wolf Hollow and Colorado […]

Coal has dominated fuel choices in Asia since 2010, even in gas-centric Southeast Asian countries, and many forecasts assume that coal will remain the region’s most economical option. But lower natural gas prices and individual market conditions are putting a dent in coal’s future in the region, some experts note. According to Graham Tyler, Wood […]

The life of a wind turbine can be pretty precarious. The blades—made of laminated materials, such as composites, balsa wood, carbon fiber, and fiberglass—can reach speeds up to 180 miles per hour at the tip, which means even small particles in the air can cause damage to the surfaces. It’s probably no surprise that lightning […]

With plans for a “permanent” solution for storing waste from nuclear power generating plants permanently stalled, some are hoping that an “interim” site can be developed that would enable the removal of spent nuclear fuel from plant sites. Today, Holtec International and two New Mexico counties announced a memorandum of agreement to build such a […]

Estimates vary widely, but even the Environmental Protection Agency acknowledges that lowering the ozone standard will cost billions. How will it affect power companies? It could make approval of new projects much more difficult. Even in the annals of expensive environmental regulations and the hyperbole that often accompanies them, the numbers are eye-popping: $140 billion […]

Minimizing the impact of electrical fires in power plants requires a combination of prevention, compartmentalization, detection, and suppression strategies. But first, everyone in a plant needs to understand the hazard. Fires at electric generating stations are rare—but not as rare as one might think. Loss history at hydroelectric facilities, for example, shows that fires involving […]

Everyone loves efficiencies. Combining generation technologies can create a plant that’s more than the sum of its parts, but engineering challenges mean these projects are not for the faint of heart. When you think of “hybrids” these days, your first thought is probably of automobiles. But hybrids—hybrid power plants, that is—are starting to emerge in […]
