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 […]

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

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
