A draft copy of a document outlining India’s latest National Electricity Policy (NEP) reportedly shows the country is considering building new coal-fired generation capacity, even as it sets new carbon reduction targets. The document also said government officials would push for better technology to help reduce emissions from those plants. Reuters on April 19 reported […]

Flexible plant operations are highly desirable in today’s power generation industry. Every plant owner desires increased ramp rates and the ability to operate at lower loads so their plants will remain “in the money” longer in today’s competitive power markets. This goal, while laudable, remains elusive. The ADEX self-tuning artificial intelligence (AI) system allows plants […]

Bleeding financially from underperforming and legally burdened coal generation in downstate Illinois and elsewhere, Vistra, the nation’s largest competitive generator, has renewed its call for passage of the Illinois Coal to Solar and Energy Storage Act, a bill that could help keep 2.2 GW of existing at-risk capacity online through 2025 while the state expands […]

A major chunk of President Joe Biden’s $2.25 trillion transformational plan to overhaul the nation’s infrastructure is dedicated to re-energizing America’s power infrastructure. The initiatives garnered the industry’s approval—with notable exceptions. The “American Jobs Plan,” released on March 31, strives to jumpstart the U.S. economy, which drooped under burdens posed by the COVID-19 pandemic. But […]

As the existing electric generation infrastructure matures, electric generation system owners are looking to the future for newer and greener technologies to meet the demands of electric consumption. An important part of this future perspective may include the demolition and removal of older generation plants and facilities to free up land resources for new development.  Prior […]

COMMENTARY Throughout my career—and also POWER magazine’s long history—thermal power generation has been the greatest source of dispatchable electricity generation. In my view, policymakers have run a very good and smooth evolution of power generation diversity off the rails. The Biden Administration and Democrat Congress policies constitute an anti-American war on carbon. These policies, if […]

The U.S. Environmental Protection Agency (EPA) has issued an update and finalized a pollution rule that will require reductions in ozone emissions from power plants in 12 states this year. The update to the Cross-State Air Pollution Rule (CSAPR), issued March 15, is designed to curb emissions of nitrogen oxide (NOx)—primarily from coal-fired power plants—ahead […]

When evaluating resource adequacy requirements, many power companies and grid operators have used a methodology that originated more than 70 years ago. This probabilistic reliability approach has generally performed adequately through the years. It has generally evaluated loss-of-load events occurring at frequencies of one-day-in-10-years (1-in-10) to be acceptable in terms of system reliability. However, it’s […]

The Electric Reliability Council of Texas (ERCOT) in freshly revealed data on March 4 reported that the Texas grid suffered 1,796 generating or energy storage outages or derates as winter storm Uri bore down on the state in mid-February.  The grid operator made the list public in a letter it sent to lawmakers in the […]

Global technology heavyweights Shell and Mitsubishi Heavy Industries, Swedish state-owned energy firm Vattenfall, and German municipal heat generator Wärme Hamburg are teaming on a massive project to repurpose a 2015-commissioned 1.6-GW coal plant in northern Germany as a massive green hydrogen hub.  The four companies in January said they signed a letter of intent to […]

The plan to retire the last coal-fired units at a power plant in Colorado has moved a step closer to completion, with the announcement that Colorado Springs Utilities (CSU) has chosen General Electric (GE) technology to keep the plant operating at least temporarily as a gas-fired facility. GE on Feb. 10 announced that six of […]

NIPSCO uses a large reservoir for settling out suspended solids prior to discharging the water back to the Kankakee River. This water is rich in nutrients, causing algae to grow at an undesired rate. Algae has a direct effect on pH and TSS levels in water. By using LG Sonic MPC-Buoy systems, NIPSCO has improved […]

The Columbia Energy Center, a two-unit 1,100-MW coal-fired station located in Columbia County, Wisconsin, south of Portage, will be permanently retired by the end of 2024.    Alliant Energy, which co-owns the facility with Wisconsin Public Service Corp. (a subsidiary of WEC Energy Group) and Madison Gas and Electric Co., made the announcement on Feb. […]
