India and 73 other countries submitted their carbon emission reduction targets for 2025 and 2030—or Intended Nationally Determined Contributions (INDCs)—ahead of the deadline last week, with just two months remaining until talks to confront climate change are due to begin in Paris.  The United Nations (UN) has so far received 120 separate pledges covering 147 […]

Rooftops with arrays of tiny wind-powered microturbines and hydro microturbines generating power as water flows through municipal drinking water systems or the outflow of municipal sewage treatment systems?  They’re real. For many in the electric power business, the term “microturbine” conjures up images of small, gas-fired machines, a fad a decade ago that never caught […]

Utility-scale energy storage in the form of pumped water storage has a long history. One of the oldest U.S. plants found itself in need of an upgrade after 40 years of service. Having the right equipment for the job is proving to be essential. With the current power market challenges and increasing amounts of variable […]

Hydropower is booming, but unless you live in China, Latin America, or Africa, you may have missed it. Global installed capacity of hydroelectric generation has grown by more than 25% over the past decade

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 […]

For decades, hydropower plants were mainly built and operated as a cost-efficient source of clean electricity. But despite more than a century of development, there is still scope for expanding generation from

The 335-MW Waneta expansion completed this June near Trail, British Columbia, adds a second powerhouse downstream of the Waneta Dam on the Pend-d’Oreille River, near the border between Canada and the U.S. (Figure 5). 5. Second powerhouse. The Waneta Expansion Limited Partnership this June connected the Waneta Expansion Project near Trail, British Columbia, to the […]

Australian firm Carnegie Wave Energy, operator of the Perth Wave Energy Project—the world’s first commercial-scale, grid-connected wave energy array—is on target to take its CETO technology to the next stage with a four-fold improvement on a dollar-per-MW basis, CEO Greg Allen said. The Perth Wave Energy Project employs three 10-meter-diameter buoys that generate about 5% […]

The global hydropower sector has seen an upsurge in development activity lately, with installed capacity growing by 27% since 2004 (Figure 2), a new report from the World Energy Council (WEC) suggests. 2. World hydropower development. Hydropower development around the world stalled from 1999 to 2005, reflecting the impact of the World Commission on Dams, […]

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 […]
