The entire state of South Australia suffered a blackout on the afternoon of September 28. The cause of the event has been disputed, but it has left Australians in a raging debate about the state of the country’s electricity system and policies that will shape its future power mix. The so-called “Black System” event that […]

As energy storage becomes more ubiquitous and projects grow in size and capacity, utilities of all types are exploring the best ways of putting it to use across the grid. The opportunities are large, but so are the challenges, according to a panel of executives who spoke at Energy Storage North America in October. New […]

Refurbishment of OPG’s Darlington Units Begins. Work to refurbish Ontario Power Generation’s (OPG’s) 3.5-GW Darlington Nuclear Generating Station kicked off on October 15. The refurbishment of the four Darlington reactors, which have provided about 20% of Ontario’s power since they went into service in the early 1990s, will span 10 years. The project is estimated […]

French multinational power company ENGIE on October 20 inaugurated a mini-network comprising 16 kW of solar photovoltaic panels, a 45-kWh lithium-ion battery bank, and a back-up genset to supply power to Ketumbeine, a village in northern Tanzania with about 800 residents. The PowerCorner project (Figure 6) was launched in early 2015. ENGIE said the project […]

China’s third nuclear reactor built for the export market, Chashma Nuclear Power Plant Unit 3, was connected to Pakistan’s grid in mid-October. Chashma 3 is one of two Chinese-designed CNP-300 pressurized-water reactors being built on the site in Punjab Province. Unit 3 is expected to enter commercial operation at the end of 2016 and Unit […]

Increasing plant efficiency and reducing maintenance costs is important for economic power plant operation. One part of the task involves keeping the boiler heating surfaces as clean as possible, which increases heat transfer, reduces maintenance, and avoids unplanned standstills of the plant. Shock pulse generators (SPGs) are an innovative and efficient way to manage boiler […]

It’s often said that technology runs well ahead of the law. Not so long ago, the process of setting electric utility rates was only slightly more dramatic than watching paint dry. This was by design. There was generally only one goal—keeping the lights on—and everything else was structured to support it. The utility generated the […]

Owner/operator: SolarReserve Three-and-a-half hours north of Las Vegas, in a rocky, desolate stretch of Nevada desert, an innovative solar-storage plant has nearly completed a year of commercial operations. It also may have delivered proof of round-the-clock dispatchable solar energy. The Crescent Dunes Solar Energy Project, a concentrating solar power (CSP) plant built by Santa Monica, […]

Donald Trump’s stunning victory in the U.S. presidential election portends enormous changes in U.S. energy and environmental policy, and a nearly complete turnover of the men and women who will administer that policy for the next four years.

As installed capacity in the U.S. continues its breakneck growth, the solar photovoltaic sector is poised for another leap forward with a variety of new technologies—if increasingly ill-suited regulations and rate designs can be updated to keep pace. The global solar market has moved beyond its early, uncertain days. The luxury of behaving like start-ups […]
