Academics at the University of Sheffield—a public research university in the UK—have begun two new carbon capture and storage (CCS) projects, searching for cheaper methods of capturing carbon dioxide (CO2) from fossil-fueled power plants. The work is being funded by the European Commission’s (EC’s) Horizon 2020 Low Carbon Energy program. Solvents Could Be Game-Changing The […]

Mississippi Power’s integrated gasification combined cycle (IGCC) power plant under construction in Kemper County, Miss., will likely be placed in service by November 30, a month later than anticipated. The delay will be costly. Mississippi Power reached a new milestone on September 16, announcing that it had started producing syngas using the second gasifier—gasifier “A”—at […]

Public Service Enterprise Group (PSEG) will close the 620-MW Hudson Generation Station in Jersey City, N.J., and the 632-MW Mercer Generation Station in Hamilton Township, N.J., on June 1, 2017. “The sustained low prices of natural gas have put economic pressure on these plants for some time. In that context, we could not justify the […]

When a gas turbine goes down, recovery can be an expensive, time-consuming process. Knowing what can go wrong and how to anticipate turbine failures can help you avoid a difficult unplanned outage. Gas-fired power is hot and getting hotter. The Energy Information Administration estimates that 2016 will be the first year ever that the U.S. […]

Oral arguments on the merits of the Environmental Protection Agency’s (EPA’s) Clean Power Plan were concluded before an en banc panel (10 judges, rather than the anticipated three) at the D.C. Circuit Court of Appeals on September 27. West Virginia v. Environmental Protection Agency (No. 15-1363) is arguably the most important environmental case in nearly […]

States, regulators, and market participants have in recent years called attention to a trend concerning uneconomic baseload generation in organized wholesale markets, specifically in ISO New England, New York Independent System Operator (NYISO), MISO, PJM, the Electric Reliability Council of Texas (ERCOT), and the California Independent System Operator (CAISO). Cheap natural gas, low power demand […]

In an effort to become a fully regulated power company, American Electric Power (AEP) has agreed to sell four Midwestern power plants—representing a total of 5.2 GW—to a newly formed joint venture of Blackstone and ArcLight Capital Partners for about $2.17 billion.  AEP will sell: the 1,186-MW natural gas–fired Lawrenceburg Generating Station in Lawrenceburg, Ind. […]

In response to what was a record earthquake for the country, four of South Korea’s 25 nuclear power plants have been shut down as a precautionary measure.

Talen Energy’s two-unit Martin’s Creek Power Plant in Mount Bethel Township, Penn., was forced offline as a result of a transformer fire Sept. 11, the company said. The incident occurred Sunday evening at a transformer yard adjacent to the plant. The fire was extinguished by local firefighters after about three hours. The plant was not […]

A merger proposed between Canadian firm Enbridge and Houston-based Spectra Energy Corp. could create the largest energy infrastructure company in North America. The companies announced on September 6 that they have entered into a definitive agreement to combine in a stock-for-stock merger transaction that has an enterprise value of $127 billion. The transaction was reportedly […]

Updates finalized by the Environmental Protection Agency (EPA) to its Cross-State Air Pollution Rule (CSAPR) identify nitrogen oxide emission (NOx) reductions from power plants in 22 states to help states address transported pollution under the agency’s more stringent 2008 ozone air quality standards. It marks the first time the EPA has updated an existing program […]

If wind and solar photovoltaic (PV) penetrations in the Eastern Interconnection were amped up to 30%, they would decrease coal, combined cycle, and combustion turbine capacity factors by 30% to 50%, a new study from the National Renewable Energy Laboratory (NREL) suggests. The study, NREL’s Eastern Renewable Generation Integration Study (ERGIS), was released on August […]

Owner/operator: Louisville Gas and Electric Co. and Kentucky Utilities Kentucky has always been coal country, but times are changing, and its generation fleet is changing with them. Facing the prospect of costly emissions control upgrades at the 60-year-old Cane Run Generating Station, Louisville Gas and Electric and Kentucky Utilities opted to retire the aging facility […]

Owner/operator: A2A When a plant goes into mothballs—especially because of poor economics—it’s often a harbinger of impending retirement. Upgrades to improve performance may help, but in changing markets, returns can be highly uncertain. Italian energy firm A2A partnered with GE to return one plant to profitability with a combination of hardware improvements and cloud-based analytics. […]

To alleviate chronic power shortages, the first gas turbine unit at this fast-tracked 640-MW plant was synchronized to the grid within a record-breaking 159 days—two days ahead of schedule. The revolution in

Owner/operator: APR Energy Within roughly 90 days, APR Energy set up a 60-MW turnkey power plant—complete with novel natural gas filtration and compression solutions—to support the operations of a massive Egyptian polyethylene plant until a bigger, permanent power plant can be built. It all began in April 2013, when Egyptian Ethylene and Derivatives Co. (ETHYDCO) […]

Owner/operator: PSEG New Jersey’s second-largest power plant has been a leader since it opened in 2006, when it was named a POWER Top Plant for its use of reclaimed water for cooling and for fitting an advanced four-unit facility into a constrained brownfield site. Now PSEG’s Linden Generating Station becomes a two-time Top Plant winner […]

Owner/operator: We Energies Converting a boiler’s fuel source from coal to natural gas involves a lot of planning and reengineering. When the plant is the sole steam service supplier to a downtown metropolitan area, it also involves a rigid schedule. The Valley Power Plant overcame several challenges to successfully complete one such conversion. The Valley […]

As combined cycle gas turbine plants are called upon to play a larger and more flexible role in the generation mix, it’s important to schedule a comprehensive assessment of major components at key intervals to ensure reliable operation. Just like humans, power plants can benefit from regularly scheduled condition assessments, which are sometimes called “health […]

Fourteen research and development projects to scale up coal-based advanced combustion power systems and gasification processes and improve costs and endurance of solid oxide fuel cells (SOFCs) have won investments of more than $28 million from the Department of Energy (DOE).
