Back in the early 2000s, some controversy emerged about the practice of spraying large amounts of fog directly into the compressor. Some claimed that this led to blade erosion, pitting, and scaling. So, is it safe to use wet compression on gas turbines by pumping water droplets into the compressor inlet? The answer is yes—provided […]

The Texas Energy Fund (TEF), a flagship loan program designed to boost the state’s dispatchable generation, faced its first setback on Sept. 4 when the Public Utility Commission of Texas (PUCT) denied Aegle Power’s loan application for a 1,292-MW combined cycle generating facility in Harlingen—its second-largest shortlisted facility. The PUCT said Aegle Power’s application, filed […]

The Environmental Protection Agency (EPA) has doubled down on its stance that carbon capture is “adequately demonstrated” in a brief filed with the U.S. Supreme Court as part of a bid to urge the high court to allow the agency’s contentious Carbon Pollution Standards to remain in effect while legal challenges continue. The Supreme Court […]

Every year, I look forward to attending several power industry events. Among my favorites is the big event POWER hosts, known as Experience POWER Week. The conference will be held this year at the Renaissance

As the urgency to combat climate change intensifies, the energy sector faces unprecedented financial risks. One of the most pressing issues is the risk of stranded assets. This challenge was first brought to widespread attention by the Carbon Tracker Initiative’s 2011 report, which highlighted the financial risks associated with unburnable carbon. Now, the risk of […]

There is plenty of enthusiasm around hydrogen as a possible alternative fuel to natural gas in combustion processes. Some hope it can eventually replace natural gas in applications such as utility boilers. However, any transition to 100% hydrogen has plenty of challenges to overcome due to it having such fundamentally different combustion characteristics. This gives […]

MeeFog’s very first installation of inlet air fogging was done at Harbor Cogen in Southern California in 1991 on a GE 7EA turbine where it continues to be used for power augmentation to this day (Figure 1). When it was installed, the fogging arrays were placed upstream of the air filters. Since that time, more […]

The Public Utility Commission of Texas (PUCT) has shortlisted 17 gas-fired “dispatchable” generation projects—a combined 9,781 MW—that will advance to receive $5.38 billion in loaned funds under the Texas Energy Fund (TEF) In-ERCOT Loan Program. The 17 proposed new projects in the PUCT’s loan portfolio, chosen from 72 applications, now proceed to a “due diligence” […]

This week marks the second anniversary of the Inflation Reduction Act (IRA), a critical milestone for the section 45Q tax credit, the foundational policy for the deployment of carbon management technologies, which was further enhanced in the IRA. The 45Q tax credit provides a credit on a per-ton basis for carbon that is captured from […]

Civil unrest in Myanmar has led Singapore-based Sembcorp Industries to at least temporarily shut down operation of the 225-MW Sembcorp Myingyan natural gas-fired power plant in Mandalay. Sembcorp, part of Singapore-based and government-owned Temasek, a global investment company, on August 12 said operations at the Sembcorp Myingyan Independent Power Plant would be suspended until further […]

A New York-based power and energy infrastructure group will acquire more than 3 GW of operating renewable energy assets, along with another 8 GW of projects under development, from a Canadian company in a deal valued at up to $2.5 billion. LS Power, headquartered in New York City with offices in New Jersey, Missouri, Texas, […]

An Indiana electric utility has announced a $1.1 billion investment in that state that includes switching coal-fired units to run on natural gas, along with new solar power and battery energy storage projects. AES Indiana, a subsidiary of AES Corp., and formerly known as Indianapolis Power & Light, on August 8 said it will convert […]

Combined cycle gas turbine (CCGT) power plants started appearing on a larger scale in the late 1990s and have since then been a very efficient supplier of baseload and lately peaking capacity to the power grids. The U.S. Energy Information Administration (EIA) recently reported that natural gas–fired capacity additions are increasing in the U.S. again […]

Malaysia Slightly Moves Up Timeframe for Coal Phaseout. Malaysia will halve its coal use by 2035 and phase out coal generation by 2044, slightly earlier than previously anticipated by the country’s National

There is an urgent need for accurate and efficient emissions monitoring technologies to ensure air pollution is adequately controlled. Infrared spectroscopy and precision infrared filters play a critical role

The U.S. Supreme Court recently overturned the longstanding Chevron doctrine, a foundation of administrative law for 40 years, when it ruled on Loper Bright Enterprises v. Raimondo . The impacts on a wide

Prices at PJM Interconnection’s 2025/2026 base residual auction (BRA) spiked to $269.92/MW-day for most resources in the wholesale power market, pointing to a tightening supply-demand balance that could have significant implications for the regional transmission organization (RTO). The 2025/2026 BRA—a competitive capacity auction that procures power supply resources in advance of the delivery year to […]

Japan’s largest utility said it will start the first of three units at a new natural gas-fired power plant near Tokyo in an effort to provide more electricity during the peak summer demand season. JERA on July 26 said the 780-MW Unit 1 at the Goi site in Chiba will enter service August 1. The […]

The California Hydrogen Hub and the Pacific Northwest Hydrogen Hub have garnered a combined $57.5 million in the first tranche of funding under the Department of Energy’s (DOE’s) $7 billion Regional Clean Hydrogen Hubs (H2Hubs) program. H2Hubs, managed by DOE’s Office of Clean Energy Demonstrations (OCED), is backed by funding from the Infrastructure Investment and […]

Former U.S. Sen. Mary Landrieu (D-La.), who is now a senior policy advisor for the law firm Van Ness Feldman and co-chair of the Natural Allies Leadership Council, is keen on natural gas and believes it is part of the solution to reaching both domestic and global climate goals. “Natural gas in America is not […]

Platte River Power Authority’s board of directors approved the utility’s 2024 Integrated Resource Plan (IRP) on July 25, including the recommended “optimal new carbon” portfolio that adds 760 MW of new renewable energy projects between now and 2030. “We’ve heard from numerous community members throughout this process and I appreciate how transparent Platte River continues […]

The U.S. Court of Appeals for the District of Columbia has denied motions to stay a suite of Environmental Protection Agency (EPA) regulations that champion carbon capture and storage (CCS) technology as a key pathway for reducing greenhouse gas emissions (GHGs) from fossil fuel-fired power plants. The rules face legal challenges from 24 states, eight […]

In 2018, Cooperative Energy, a generation and transmission co-op headquartered in Hattiesburg, Mississippi, had an issue to deal with. Several years earlier, it had joined the Midcontinent Independent System Operator (MISO), giving the power provider access to a competitive market. However, Cooperative Energy’s R.D. Morrow Sr. Generating Station, a 400-MW two-unit coal-fired facility that had […]

Higher prices for natural gas across Europe mean some countries, particularly in Eastern Europe, likely will burn more coal for power generation during the upcoming winter season. Coal remains a large part of the energy mix in Germany—the largest energy consumer in Europe—as well as other countries such as Poland, Bulgaria, the Czech Republic, Romania, […]

Unitil Corp., the largest provider of natural gas in Maine, on July 9 said it has a deal to purchase Bangor Natural Gas Co., which has been the state’s No. 2 provider of the fuel.
