California’s grid gurus say they can make it through this summer, but the future may pose real problems for a hydro-heavy regional system. As the grip of California’s four-year drought tightens, will the long-running event crimp electricity generation in the state? So far, according to the California Independent System Operator (CAISO), which dispatches much of […]

At Tennessee Valley Authority (TVA), repeated generation transitions have marked the giant public power utility’s long history, from hydro, to coal, to nuclear. The latest resource plan points to natural gas, along with renewables and energy efficiency, as the basis for the agency’s generating future. At the Tennessee Valley Authority (TVA), generation transitions are nothing […]

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 […]

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 […]

The U.S. Department of Energy, U.S. Department of the Interior, and the U.S. Department of the Army for Civil Works announced on March 24 that the three agencies would continue to collaborate on hydropower development for at least another five years. The agreement extends a memorandum of understanding (MOU) the three agencies originally signed in […]

The ongoing record drought in California has caused significant changes in the state’s power mix as water available for hydroelectric generation becomes increasingly scarce, according to a recent report from Oakland-based nonprofit the Pacific Institute. The California Independent System Operator warned last year that water shortages were likely to substantially impact the state’s generation, with […]

The 338-MW Russey Chrum Krom hydropower plant in southwestern Koh Kong province, Cambodia, was inaugurated on Jan. 12. The Chinese-built project is the largest hydropower station located in the Southeast Asian

The world’s ocean energy sector, which has over the past few years seen its share of developmental ebbs and flows, suffered a major storm this November after Siemens Energy said it would sell its tidal power arm and Pelamis Wave Power separately failed to raise needed funds to continue development. Siemens in February 2012, with […]

As the global electric power industry continues to develop clean, high-quality energy capacity for sustainable development, the position of small hydropower has changed. In the past few decades, small hydropower development in China has experienced positive momentum, but there are still problems to be solved. To solve these problems, various relationships within the small hydropower […]

In China, small hydropower (SHP) development not only provides power, especially to rural areas, but it also plays an important role in developing local economies and human capacity building. Regions, rather

Water and energy are intimately linked. Water is necessary for the production, distribution, and use of energy. Energy is needed for the withdrawal and delivery of water. The two are inseparable. Several

Renewables’ share of the global power mix is slated to overtake coal to become the largest source of electricity by 2040, the International Energy Agency (IEA) projects in its 2014 edition of the World

Like many small countries, Albania is dependent on a specific generation type for the majority of its electricity. In the case of this mountainous nation of 3 million people, it’s hydropower. Roughly 98% of

The U.S. Census Bureau released data on Nov. 18 showing that revenues for electric power generation industries that use renewable energy resources grew 49% from 2007 to 2012, while fossil fuel electric power generation industry revenues decreased 6.7% during the same time period. Fossil fuel revenues continued to dwarf renewable totals, bringing in $79.7 billion […]

The decision to eliminate coal-fired power plants and the implementation of an aggressive feed-in tariff program puts Ontario’s electricity system in the spotlight. Download a pdf of this sponsored report, written by Global Business Reports: GBR_ONTARIO_PWR_1114_sm

A lack of rainfall is hitting the power industry especially hard in parts of Brazil. According to the U.S. Energy Information Administration (EIA), the country depends on hydroelectricity for more than 75% of its electric power supply (Figure 2). But with reservoir levels at historic lows in some places, more electricity has been required from […]

Last winter’s polar vortex was a reminder that, despite several years of mild winters, colder months can still pack a wallop. Decades of coal, gas, and nuclear plant operations have taught plant operators

Can hydropower get some love? Even fans of renewable energy can be forgiven for having forgotten about a resource that—up to now—has produced more electricity than wind, solar, biomass, and all other

The Montana Public Service Commission (MPSC) on Sept. 4 approved Northwestern Energy Corp.’s request to purchase 11 hydroelectric power plants in the state from PPL Montana for $880 million. The plants, which comprise PPL Montana’s entire hydroelectric profile, total 630 MW of generation. Nine are run-of-river plants; the other two, the Mystic Lake Dam in […]

Commissioning of all 18 generating units at China’s 13.9-GW Xiluodu Hydropower Station has been completed, making it the world’s third-largest hydroelectric project (Figure 5), China Three Gorges Corp. announced in early July. 5. Hydropower giant. Commissioning of all 18 generating units at China’s 13.9-GW Xiluodu Hydropower Station has been completed, making it the world’s third-largest […]

Consensus is that the locus of world energy demand has shifted away from the U.S. and Europe to Asia, driven by the soaring economies of the 10 countries that make up the Association of Southeast Asian Nations

As the latest development in a contentious eight-year-long legal battle, Chile’s highest administrative authority in early June revoked environmental permits for five massive dams proposed in the country’s

British Columbia (BC) has long enjoyed some of the lowest electricity costs in North America, but when in August 2013, a draft of the BC Rates Plan which proposed a 26% rate increase by 2016, was leaked, this was met with such a backlash of protest that the government was forced to reconsider the proposal. […]

At the Edison Electric Institute (EEI) annual meeting this week in Las Vegas, the tone was one of collaboration with partners from Washington to distributed generation companies. Those partnerships will be needed as the investor-owned utility (IOU) industry fights not so much a war on coal as a war for mindshare and wallet share in […]

Brazil’s Belo Monte hydropower project includes a complex of dams, numerous dikes, and a series of canals supplying two different power stations with water. With a rated capacity of 11,233 MW, it will be the

The Himalayan Mountains tower over some of the most rugged terrain and harshest climate conditions on the planet. Melting snows from Mount Everest, K2, and hundreds of other snow-capped peaks carve out more

After a lull that spanned nearly two decades, a hoard of new massive hydropower projects are being developed around the world. Some, like the 11.2-GW Belo Monte dam in Brazil, the 4.5-GW Diamer-Bhasha project
