  • Understanding Electrical Fire Hazards at Electric Generating Stations

    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 […]

  • Leveraging Generation Synergies with Hybrid Plants

    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 […]

  • Two Years Later, S. Korea Finally Puts Shin-Wolsong 2 Online

    In South Korea, the second unit at Korea Hydro and Nuclear Power’s (KHNP’s) Shin-Wolsong reactor (Figure 3) was finally connected to the grid in late February. 3. Finally connected. Korea Hydro and Nuclear Power’s Shin-Wolsong 2 was grid-connected in late February, nearly two years after it was completed. Courtesy: KHNP Though the reactor was completed […]

  • Study: Perovskite-Silicon Tandems Provide Big Boost to Solar Efficiency

    Stacking perovskites, a crystalline material, onto a conventional silicon solar cell may dramatically improve the overall efficiency of the cell, scientists from Stanford University concluded in a new study. “Right now, silicon solar cells dominate the world market, but the power conversion efficiency of silicon photovoltaics has been stuck at 25% for 15 years,” explained […]

  • Seismic Hazard Resiliency at U.S. Nuclear Power Plants

    Since the beginning of the U.S. commercial reactor industry, regulatory agencies have required that nuclear power plant designs take into account the potential threats posed by natural hazards such as earthquakes and floods. The tsunami-caused disaster in Japan in 2011 prompted renewed attention worldwide on these hazards. Given the devastation caused at Japan’s Fukushima Daiichi […]

  • One Step Back, One Step Forward for U.S. Offshore Wind

    Though offshore wind is becoming increasingly important in Europe, with many hundreds-of-megawatts projects in service, the sector has stagnated in the U.S., with no operational facilities—and some

  • China’s Hualong One Reactor Design Gets Argentine Boost

    Argentina’s Ministry of Federal Planning in early February signed an agreement with the National Energy Administration of China and China National Nuclear Co. (CNNC) to build Argentina’s fourth nuclear reactor, an 800-MW CANDU design, on the site of the existing Atucha nuclear power plant. Under the agreement, Nucleoeléctrica Argentina—holder of the rights to Canadian CANDU […]

    $1.9B Pan-African Renewable Energy Platform Launched. Renewables company Mainstream Renewable Power and private equity firm Actis on Feb. 17 launched a pan-African renewable energy platform dubbed Lekela Power, with ambitions to provide between 700 MW and 900 MW of wind and solar power across Africa by 2018. Mainstream will take responsibility for the full end-to-end […]

  • Palo Verde Nuclear Station Sets U.S. Production Record

    The Palo Verde Nuclear Generating Station led the U.S. in electrical generation in 2014, as it has done for 23 consecutive years, with a total output of 32.3 million MWh. That bested its previous record set in 2012. The Palo Verde plant is located about 45 miles west of Phoenix, Ariz. (Figure 5). It has […]

  • The State of U.S. Mercury Control in Response to MATS

    As this month marks the compliance date for the Mercury and Air Toxics Standards (MATS), it’s a good time to take a step back from the many months of concern and consideration of options to see how coal-fired power plants are actually responding to the new rule. It’s also a good time to acknowledge that […]
