Utilities across the country are gearing up for an attack on the power grid November 15 and 16. Thankfully, it’s only a drill. But in the event of an actual emergency, a real physical and cyberattack on the U.S. electricity infrastructure, GridEx IV—a biennial exercise conducted by the North American Electric Reliability Corp. (NERC)—will help […]

The U.S. House of Representatives on November 2 proposed a tax bill that would phase out the wind energy production tax credit (PTC), extend a tax credit for the nuclear power industry, add credits for geothermal and fuel cell programs, and end a tax credit for the purchase of electric vehicles. Wind energy proponents decried […]

The first of three 110-MW units at the $1 billion Sarulla geothermal power plant in Indonesia’s North Sumatra province commenced commercial operation this March. When the next two units come online as

Technology advancements and new regulatory requirements could reshape how power plant owners operate and maintain large power transformers. Experts outline emerging strategies and call attention to overlooked

China rolled out its latest five-year energy development plan, detailing the country’s aim of investing about 2.5 trillion yuan (more than $363 billion) through 2020 in the development of renewable energy resources. Yang Li Zhe, deputy director of China’s National Energy Board, explained the country’s vision during a press conference held in Beijing on January […]

Owner/operator: Akca Enerji Geothermal energy has long been handicapped by its need for high-temperature resources to generate economic power, but innovations in binary Organic Rankine Cycle systems are making it possible to exploit low-temperature sites. An innovative plant in Turkey using Italian technology has taken things a step further with a unique two-pressure, multistage, single-disk […]

Panelists debating the pros and cons of a regionalized western power grid seemed to agree that the development of such a system is inevitable, but they disagreed on how fast the evolution should occur. The panel discussion took place during the California Independent System Operator (ISO) Stakeholder Symposium held on September 7 in Sacramento. At […]

  The Environmental Protection Agency (EPA) has unveiled details of the Clean Energy Incentive Program (CEIP), a voluntary measure central to the judicially stalled Clean Power Plan that seeks to provide guidance to states and tribes that want to meet goals under the plan when it becomes effective. The final Clean Power Plan, finalized in […]

The world’s frenzied economic growth through 2040 won’t be matched by electricity demand growth, the Energy Information Administration (EIA) says in the International Energy Outlook 2016 (IEO2016 ) released on May 11. World net electricity generation will jump 69% by 2040, the IEO2016 reference case projects, but that is still well below “what it would […]

Hands down, 2015 was a record year for global investment in renewable energy. Excluding large hydroelectric projects, the amount of money committed to renewables rose 5%, to $285.9 billion, exceeding the previous record of $278.5 billion reached in 2011.

By an 85-12 vote, the U.S. Senate passed the first comprehensive energy bill in nearly a decade, bringing a successful conclusion to months of legislative effort and overcoming a series of roadblocks in the full Senate related to the water quality crisis in Flint, Mich. The product of more than a year of bipartisan work […]

The Great Rift Valley is a massive continental fault system that runs 6,000 kilometers (km) from Mozambique to Jordan. In Kenya, the East African nation that is neatly halved by the equator, the Rift Valley is

After years of stressing the conventional virtues of geothermal power production—reliable, baseload renewable energy from geological sources—the geothermal industry and the U.S. government are looking at ways technology can change the hot rocks game and give a boost to an often-overlooked resource. Legendary venture capitalist Vinod Khosla, who made a pile of money in information […]

Parts of Calpine Corp.’s The Geysers geothermal power complex have been severely damaged by a wildfire that has incinerated swathes of California.  One of the world’s largest geothermal facilities, the 725-MW Geysers complex sits on 45 square miles of land along the border of Sonoma and Lake Counties in Northern California. Calpine said at least […]

Nuclear costs aren’t on the rise globally as has been widely thought, says a new report from the International Energy Agency (IEA) and Nuclear Energy Agency (NEA) surveying the levelized cost of generating electricity (LCOE).  The eighth edition of the report, “Projected Costs of Generating Electricity” compiles data for 181 plants in 19 OECD and […]
