A report from a Colorado-based group that provides analysis and market reports to the energy industry says an Alabama power plant has the highest emissions of carbon dioxide (CO2) of any coal-fired facility in the Lower 48 states.

BTU Analytics in a report released April 29 ranked the James H. Miller plant in West Jefferson, Alabama, about 20 miles northwest of Birmingham, as the largest CO2 emitter. The plant has four coal-fired units, the first of which came online in 1978, with Unit 4 entering operation in 1991.

The report, which lists the 10 U.S. plants (Figure 1) with the highest level of CO2 emissions, comes as many groups, including the U.S. Dept. of Energy (DOE), look at ways to support technologies designed to make coal plants more efficient and to reduce their emissions of pollutants. The DOE on April 23 announced $ 75 million in funding to engineer carbon capture projects; the DOE’s Loan Programs Office (LPO) also said it has $ 8.5 billion in funding for carbon capture projects through LPO’s Title 17 Innovative Energy Loan Guarantee Program.…

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 to continuously optimize plant performance at any operating point rather than being constrained to a static “design point” commonly found in gas- and coal-fired plants. Better yet, no changes to the plant distributed control system (DCS) are required.

Renewable energy resources, coupled with internet technologies and emerging large-scale energy storage, fundamentally change the modern electricity markets. Wind and photovoltaic electricity resources have proved to be the most disruptive renewable energy technologies over the past few years and will continue to do so. The challenge for grid operators is managing these disparate electricity providers to match weather-dependent supply with consumers demanding more independence and flexibility to manage personal demand patterns.…

GE CC plant in Malaysia

General Electric (GE) will provide two of the company’s 9HA.01 gas turbines along with other equipment and services to a new power plant in Malaysia. The company on March 24 announced it secured an order from a consortium of three groups, including Mitsubishi Corp., that is serving as the engineering, procurement, and construction (EPC) lead for the project.

The 1.2-GW Pulau Indah Power Plant is sited in Selangor, Malaysia. The two-block combined cycle plant will feature a modular configuration, according to GE. It also will include an STF-D650 steam turbine, a W88 generator, and a once-through heat recovery steam generator (HRSG). GE said the “HRSG technology is a key enabler in advanced water-steam cycles delivering higher combined cycle efficiency, while GE’s 9HA is the company’s flagship and most efficient 50 Hz gas turbine.”

Modern HRSG Designs Maximize Combined Cycle Plant Efficiency

The post Modern HRSG Designs Maximize Combined Cycle Plant Efficiency appeared first on POWER Magazine.

Iberdrola SA and Mitsubishi Hitachi Power Systems (MHPS) recently commissioned the El Carmen combined cycle plant, located in Nuevo León, northeast Mexico. Wood supplied the two horizontal heat recovery steam generators (HRSGs) for the plant. The 875-MW combined cycle plant is based on two 300-MW MHPS M501J combustion turbines and is the first plant built in Mexico to sell power directly to industrial customers through its wholesale power market in over 70 years. CFEnergia, a subsidiary of CFER, delivers natural gas to the plant.

Mexico began deregulating its electricity market in 2013 with wholesale trading commencing in 2016. The reforms opened the electricity market to private investors to increase market competition, and to accelerate the expansion and modernization of Mexico’s power generation infrastructure. Until 2013, all facets of the electricity market, from generation to distribution, were the exclusive domain of the state-owned Comisión Federal de Electricidad (CFE), an integrated monopoly, and private participation was limited to the generation of power not intended for public consumption.…

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. 2. It said Unit 1 would be shuttered by the end of 2023, with Unit 2 closed the following year.

“The closure of Columbia is truly a historic moment as we stop burning coal in our Wisconsin Operations and fully turn our attention to generating cleaner energy using renewable resources, such as solar, battery storage and high efficiency gas,” David de Leon, president of Alliant Energy’s Wisconsin energy company, said in a statement.

Alliant Energy has set goals of cutting CO2 emissions in half by 2030, and eliminating all coal from its generation fleet by 2040.…

Five Reasons Remote Technology Makes Sense Even If You Never Plan to Operate Your Power Plant Remotely

The post Five Reasons Remote Technology Makes Sense Even If You Never Plan to Operate Your Power Plant Remotely appeared first on POWER Magazine.

The case for advanced analytics and remote diagnostics

During the last 25 years significant advancements have been made in remote monitoring capabilities for power plants. A number of operations and maintenance (O&M) functions can routinely be managed remotely, and it is also becoming more common for peaking and renewable energy plants to be remotely operated reliably and safely.

Operating and maintaining a full-scale power plant remotely presents challenges that require sophisticated systems, reliable sensor and diagnostic equipment, stable high-bandwidth communication, and advanced security protocols. Even with progress made in each of these areas, some plant managers don’t foresee a scenario where remote operations will become the norm. But even in cases where there are no plans to run a generating station from a remote location, there is still a solid case for adopting remote technology.

Here are five reasons why the case for remote technology is stronger today than ever before.…
