An executive with the parent company of Tampa Electric said the utility plans to seek regulatory approval to convert its Big Bend Power Station in Florida, the oldest and last major coal-fired facility in its fleet, to natural gas. Rob Bennett, speaking at a breakfast gathering in Tampa on January 12, said an engineering analysis […]

In a press briefing held with Norwegian Prime Minister Erna Solberg on January 10, President Donald Trump said that U.S. could “conceivably” re-enter into global climate change mitigation efforts under the Paris accord. While he has “no problem” with the accord itself, he felt the agreement negotiated by the Obama administration treated the U.S. unfairly, […]

The U.S. Energy Information Administration (EIA) released its first look at expected power generation in 2019, and its conclusions are much the same as those it expects in 2018—the use of natural gas to produce electricity will continue to rise, and the use of coal will continue to decline. EIA’s Short-Term Energy Outlook, released January […]

Florida Power & Light (FPL) began the new year by opening four new solar power plants, along with officially retiring one of its two remaining coal-fired plants in the state. The utility on January 8 said the four solar plants began operating on January 1, 2018. They are the Horizon Solar Energy Center, in Alachua […]

The Johnsonville Fossil Plant in Humphreys County, Tennessee, came online in 1951, and provided power for generations of Tennesseans as part of the Tennessee Valley Authority’s (TVA’s) vast coal-fired fleet. But the end of 2017 also marked the end of an era for Johnsonville, as the TVA shut down the last operating unit at the […]

The Federal Energy Regulatory Commission (FERC) has rejected the Department of Energy’s (DOE’s) controversial proposed rule on grid reliability and resilience pricing, initiating instead a new proceeding that will examine the resilience of the bulk power system. The DOE’s “Grid Resiliency Pricing Rule” proposed on Sept. 29 directed FERC—an independent regulatory government agency that is […]

All power plant equipment has a limited lifetime, but not all components age at the same rate. Some equipment may outlast the useful life of a plant, while other machinery may be replaced more than once

Merchant markets for independent power producers in the U.S. are unfavorable, and many companies in the sector have slumping profits—even big losses—as they ponder where to go in the months and years

It is estimated that nearly 240 million Indians currently do not have access to electricity. In many cases that also means a lack of access to adequate health care or educational opportunities. It is no

Engineers from several companies have worked on upgrades to the technology, including designs that emphasize faster starts, quicker ramp-ups, increased efficiency, and better performance in a tight global

There are challenges facing the power industry in 2018, but there are also a lot of exciting opportunities. Renewable energy and gas-fired generation are expected to continue growing, but changes in federal

There are many tools available to assist companies as they gain a better grasp on how their energy is being used, and what that means for the goal of efficient energy management. Not all solutions are created

As power plants and substations become more connected, the need for rugged networking equipment built to withstand tough conditions is amplified. The military has already gone through the growing pains, so

The James M. Barry Electric Generating Plant, both a coal-fired and natural gas-fired facility in Bucks, Alabama, sits on the west bank of the Mobile River. The facility’s coal is delivered via the river

The amount of electricity produced by gas-fired power generation has been increasing steadily in the U.S. for more than 25 years. The Energy Information Administration (EIA) reports that in 1990 about 372.8

The European Union (EU) is unequivocally continuing down a path of global climate and energy leadership while bringing online more carbon-neutral fuel systems throughout its 28 member states, closing in on the 2020 goal of a 20% reduction in greenhouse gas emissions (GHG) from 1990 levels. Indeed, the newly released European Environment 
Agency’s (EEA’s) Trends […]

Owners and contractors can run into contractual disputes during combined cycle construction projects. Often, the disagreements snowball into lawsuits, which create a lot of activity in attorney offices, but can actually stop activity at the construction site. Engineers and laborers frequently end up taking off their hard hats and setting down their welding torches to […]

An energy transition is underway across the world. Market upheaval, defining events, and recent policy changes have accelerated a shift away from coal toward renewables. Here is how this transformation played out for some of the world’s major economies over the past decade. Graphs show percent of each fuel source of total generation for that […]

The project to build one of the world’s largest lithium-ion battery storage systems started out as a bet—on Twitter. Last March, Tesla CEO Elon Musk tweeted to Australian billionaire Mike Cannon-Brookes

Construction Underway on New Unit at Serbian Coal Plant. It has been almost 30 years since any new power generation capacity was built in Serbia, but that stretch is coming to an end as China Machinery and

Iberdrola’s global strategy to close its remaining coal-fired power plants has met with government opposition in its home country of Spain. Days after Iberdrola, the country’s largest utility, said it

In the next 25 years, the world will turn increasingly to renewables and natural gas to meet energy demand, turning away from coal, according to the International Energy Agency’s (IEA’s) World Energy

Siemens claims to be paving the way for the next level of efficiency with the development of its HL-class gas turbine. In June 2017, the company announced it will validate the technology at Duke Energy’s Lincoln County site in North Carolina. Siemens is developing this class in an evolutionary development step derived from its proven […]

Earlier this year, GE’s Power Services achieved a significant milestone with its 9EMax gas turbine upgrade solution. The 9EMax completed initial validation testing and was offered commercially to gas turbine customers around the globe. The first 9EMax unit was installed at a customer’s site in Asia. “First fire is a critical test where the gas […]

A Michigan utility will build a $500 million natural gas-fired power plant on the site of an existing coal-fired plant in Lansing, and plans to retire the coal plant and another coal-fired facility in the town in the next few years. Lansing’s Board of Water & Light (BWL) announced the project December 18. The city-owned […]

A utility group on December 18 agreed to keep a coal-fired power plant in Colorado Springs, Colorado, open for at least a few more years, and its members said they are prepared to move forward with distributed generation and could import power to make up for the eventual retirement of the Martin Drake Power Plant. […]

Oman recently began operating a Wärtsilä-built power plant in the northern part of the country, part of more than $1 billion in power and energy projects being developed in the Arab nation. The Musandam Independent Power Project (IPP) is a 120-MW natural gas-fired plant (Figure 1) that can use light fuel oil as a secondary […]

A report released December 14 by the North American Electric Reliability Corp. (NERC) says power generation from natural gas-fired units and renewable sources such as solar and wind will provide enough electricity to offset the closures of U.S. coal-fired and nuclear power plants in the next decade. The agency’s 10-year outlook, part of its 2017 […]

Supercritical carbon dioxide (sCO2) cycles—which are inching closer to commercial applications for waste heat recovery, concentrating solar power, nuclear, and fossil energy—offer higher thermal efficiencies and power density than conventional steam Rankine and Air Brayton cycles in use today for power generation. But to realize these potentially game-changing cycles, common challenges associated with turbomachinery must […]

Energy Secretary Rick Perry has granted a 30-day extension sought by Federal Energy Regulatory Commission (FERC) Chairman Kevin McIntyre last week to give the regulatory agency more time before it acts on the controversial proposed Grid Resiliency Pricing Rule. In a strongly worded letter, however, he told FERC to act expeditiously to allay reliability threats to […]
