Düsseldorf’s new “Block Fortuna” at the Lausward Power Plant, owned by municipal utility Stadtwerke Düsseldorf, is setting records and giving Germany’s coal-fired power plants some much-needed competition for backing up the nation’s large percentage of variable renewable power. Germany’s Energiewende (literally, “energy turn”) functions as something of a living laboratory, where innovation equals survival, because […]

We’ve all probably purchased a “lemon”—an item that didn’t work as advertised—but when that lemon is a $2.1 billion power plant, you can’t just return it. For Longview Power’s management team, taking a “belts-and-suspenders” approach to problem-solving allowed them to identify root causes, make changes, and convert their lemon into “lemonade.” Most people expect a […]

The governments of Ireland and Northern Ireland have big ambitions for their unified electricity market, including a wind-heavy 40% renewable generation target by 2020. Making that happen while delivering safe, reliable electricity to customers across the island means a sea change in how the grid is operated. One of the first big steps is installation […]

Lake Kivu, the 1,040-square-mile “killer lake” that stretches over the border between Rwanda and the Democratic Republic of Congo (DRC), has long been a source of trepidation. Because it sits between two

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

With its vast resources of oil, gas, coal, and tar sands—some of the largest in the world—the province of Alberta has long been known as Canada’s fuel tank. Coal- and gas-fired power has supplied the

Just how fast are things moving in solar? When we received the nomination for the massive Desert Sunlight Solar Farm in late April, the 550-MW facility was the largest solar power plant in the world, sharing

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

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

You can’t spell C-S-P without S-P-A-I-N. Though there are now many nations with concentrating solar power (CSP) plants in operation, and nations with larger ones than Spain possesses, it’s difficult to

Begun with grand ambitions in the early 1980s, the second unit at Argentina’s Atucha site ran smack into the country’s economic crises in the following decade. But a determined crew brought the project to completion after a 13-year hiatus through a focus on rebuilding the nation’s nuclear labor force. As with many other nations in […]

The nearly 4-GW, three-unit Palo Verde Nuclear Generating Station remains the largest generator of electricity in the U.S. for the 23rd consecutive year, producing more than 30 million MWh in 2014, for the 10th time (the only plant in the U.S. to do so), all while using only treated wastewater for cooling. Palo Verde Nuclear […]

Owner/operator: Great River Energy Recent news has focused on the decline of the coal-fired power industry, but this highly efficient combined heat and power plant offers one template for keeping coal generation viable. Although electricity markets remain challenging, partnering with steam customers can help stabilize revenue. Combined heat and power (CHP), also known as cogeneration, […]

Alliant Energy and its co-owners are investing $900 million to modernize the Columbia Energy Center with a new suite of air quality control equipment and plant improvements that will increase its output and efficiency while reducing emissions. The plant makeover ensures its continued operation for decades to come. In 2009, Wisconsin Power and Light Co., […]

Owner/operator: TNB Janamanjung Sdn. Bhd. Ultrasupercritical technology is the current gold standard for coal-fired plants, but Malaysian national utility Tenaga Nasional Berhad had some unique requirements for its newest, most efficient plant. With a client lacking an indigenous source of coal and needing wide fuel flexibility, Alstom delivered a state-of-the-art plant that can handle an […]

Owner/operator: Interstate Power & Light Co. (a subsidiary of Alliant Energy) and MidAmerican Energy Co. (a subsidiary of Berkshire Hathaway Energy) / Alliant Energy Alliant Energy recently completed a major renovation of the Ottumwa Generating Station to improve air quality, plant reliability, and efficiency. By doing so it also reduced its carbon footprint by ~5.6%.  […]

Owner/operator: NTPC Ltd. One of NTPC’s first coal-fired facilities, the 2.6-GW Ramagundam plant, is aging well, delivering noteworthy performance metrics that distinguish it from other plants in the state-owned generator’s big coal fleet. For nearly four decades, the 2.6-GW Ramagundam Super Thermal Power Station’s vermillion-banded stacks have towered over the green teak forests of what […]

Owner/operator: Shenergy Company Ltd. In a nation seeing breakneck growth in its power sector and a drive toward cleaner, more efficient generation, coal remains the backbone. That means hard work is ahead for China in power sector innovation, and a plant in Shanghai is leading the way. There is no country on earth that has […]
