The world added 33 GW of new hydropower capacity in 2015, including 2.5 GW of pumped storage, the International Hydropower Association (IHA) said in a recent brief. The new capacity made up only 3% of the

Upgrading automation systems can often extend the life of power generation facilities by decades while reducing downtime, improving operations, and reducing required maintenance. The Maggotty plant in Jamaica offers one such example. Many power generation facilities have equipment in good running order with many years or even decades of potential service life remaining, but operation […]

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 New York State Public Service Commission on January 21 approved a 10-year, $5 billion Clean Energy Fund that is expected to address climate change and strengthen resiliency in the face of extreme weather. It will also bolster Gov. Andrew Cuomo’s aggressive Clean Energy Standard, which calls for the state to meet 50% of its […]

The autonomous region of Xinjiang has an important strategic position in China’s economy—which consumes more energy than any other nation—yet several conditions limit the most effective use of its fuels. This article provides an overview of the situation. Since ancient times, the Xinjiang Uygur Autonomous Region (Xinjiang) has been in a particularly important position in […]

A significant transformation of the global power mix is under way, noted the International Energy Agency (IEA) in its newly released World Energy Outlook (WEO-2015). Renewables are getting subsidized boosts

China Makes Nuclear Export Gains in Argentina, Romania. As it boosts its domestic nuclear power capacity, China is also snapping up lucrative contracts to build new reactors abroad. This November, China

The autonomous region of Xinjiang has a strategic position in China’s economy, yet several conditions limit the most effective use of its fuels. This article provides an overview of the situation. A more detailed version, with maps and tables, appears here under the same title. Since ancient times, the Xinjiang Uygur Autonomous Region (Xinjiang) has held […]

Baranof Island is home to Sitka, Alaska. Located on the outer coast of Alaska’s Inside Passage, it is accessible only by air and sea (although once on the island, standard forms of transportation are

From space, the 12.7-kilometer (km) Sihwa Lake tidal barrage that houses a 400-meter (m)-long tidal power plant looks like a delicate strand stretched across one of many bays and inlets characterizing the

Ethiopia’s generation capacity got an immense boost as operations began at the 1.87-GW Gibe III hydroelectric power plant in the middle reach of the Omo River basin this October. The plant—Ethiopia’s

Seven power producers have joined 74 other companies in signing on to the Obama administration’s American Business Act on Climate initiative, which is aimed at rallying U.S. companies behind the need for action on climate change ahead of international climate talks in Paris next month. The seven are Berkshire Hathaway Energy (BHE)—parent company of PacifiCorp, […]

Within the space of less than a week, four deals have been announced that will result in ownership changes at five power plants in the U.S. Northeast. Calpine Buys Another Gas Plant Calpine Corp. announced on Oct. 13 that it has agreed to acquire the Granite Ridge Energy Center, a 745-MW combined cycle gas-fired power […]

A federal court last week granted a motion barring the U.S. Army Corps of Engineers and Environmental Protection Agency (EPA) from enforcing the Clean Water Rule, which critics say is “exceptionally expansive.” A three-judge panel at the U.S. Court of Appeals for the Sixth Circuit on Oct. 9 granted the stay sought by 31 states […]

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 […]
