With COVID-19 filling the news throughout 2020, it’s very likely you missed some of the most important developments that occurred in the power sector this year. Here’s a look at some of the highlights and big stories covered by the POWER staff this year. MOX Nuclear Fuel Loaded In January, Russian engineers announced the loading […]

Italy’s Enel is decommissioning one of its coal-fired power plants in Chile two years sooner than originally planned, with the unit’s closure coming two days after the Chile-based unit of a U.S. utility announced it would accelerate the closure of a pair of coal-fired power plants in the country. Enel on Dec. 31 is closing […]

Provinces across China are reportedly grappling with crippling power shortages prompted by a surge in power demand from a stunning ramp up in industrial activity, an especially harsh winter, and tight coal supplies, which may be exacerbated by a ban on Australian coal.  Power shortages have been reported in Zhejiang province, an economic powerhouse in […]

Demolition of the Navajo Generating Station, a 2,400-MW coal-fired power plant that generated electricity for several cities in the U.S. Southwest, continued Dec. 18 as explosions brought down the facility’s three large smokestacks. The plant was closed in November 2019. The NGS, located near Page, Arizona, is being demolished by Salt River Project (SRP). The […]

By 2025, the economics of low-carbon generation technologies are poised to disrupt conventional fossil fuel generation so dramatically, onshore wind could have the lowest levelized costs of electricity (LCOE) on average, and nuclear power could emerge as the dispatchable low-carbon technology with the lowest expected costs.  Those are key findings in the Dec. 9-issued 2020 […]

In a significant but controversial final action, the Environmental Protection Agency (EPA) on Dec. 7 retained its existing National Ambient Air Quality Standards (NAAQS) for both fine and coarse particulate matter (PM2.5 and PM10). While the EPA said the decision came “after careful review and consideration of the most recent available scientific evidence and technical […]

Gelsenkirchen / Germany, December 2020 By 2024, POSCO Energy of South Korea will have constructed a new coal-fired power station with two 1,050 MW generating units, in Samcheok in the north-east of the country.

The struggling U.S. coal industry, decimated by falling demand for the fuel from the power generation sector, and hit hard by low prices during the coronavirus pandemic, saw two more mining companies declare bankruptcy this week. White Stallion Energy, which operates in Indiana and Illinois, and Lighthouse Resources, a coal company with mines in Wyoming […]

Conveyors are among the most dynamic and potentially dangerous areas of equipment at a coal power plant. Even though their safety and performance are critical to the operation’s success, the impact of their contribution to overall efficiency is often unrecognized by management and workers alike. Operational basics of belt conveyor systems are too often a […]

Westminster, CO (Dec. 1, 2020) — Tri-State Generation and Transmission Association would more than double its currently contracted solar and wind resources by 2030, add energy storage, and reduce emissions to help meet the needs of its member electric cooperatives and public power districts, in the “preferred scenario” of its Electric Resource Plan (ERP) filed […]

Over its 50-year history, several rules issued by the U.S. Environmental Protection Agency (EPA) have reshaped the power sector. But for at least a few modern rules, the road has been full of turns. Notes: CAA = Clean Air Act; BSER = best system of emission reduction; CO2 = carbon dioxide; GHG = greenhouse gases; […]
