Wisconsin-based Dairyland Power Cooperative on Jan. 23 said it would close its 345-MW coal-fired Genoa Station No. 3 by year-end 2021. The move comes as the La Crosse-based utility continues to phase out coal-fired power generation while it develops a new, $700-million natural gas-fired plant, and ramps up its use of renewable power sources. The […]

The power sector has increasingly turned to various forms of distributed generation to meet growing power demands over the past several decades. Although solar PV and other renewable technologies receive most of the coverage, they represent only a fraction of the distributed market. Diesel generator sets (gensets) have long been the face of distributed generation. […]

Deal-making in the North American power and utilities sector fell for the third year in a row in 2019, and total deal value shrank by 41% compared to 2018, indicating a sustained sluggish financial interest in the sector, according to PricewaterhouseCoopers (PwC). The international accounting firm’s newly released “North American Power & Utilities deals insights […]

Arizona Public Service (APS) announced Jan. 22 that it plans for all its power generation to be carbon-free by 2050, and also said it plans to produce nearly half its power from renewable sources by 2030. APS joins other U.S. utilities who have put forth similar goals in recent years. APS, which has been criticized […]

Construction of a $700 million natural gas-fired power plant near the Wisconsin-Minnesota border was authorized by Wisconsin regulators on Jan. 16, over the objections of environmental groups who have said the plant is not needed. Dairyland Power Cooperative and Minnesota Power would jointly own the 625-MW Nemadji Trail Energy Center, which on its current timeline […]

The U.S. Energy Information Administration (EIA) in its first forecast for 2021 suggests the share of renewables in the utility-scale U.S. power generation mix will surge to 22%, up from 17% last year, while coal and nuclear’s shares will be further diminished. According to the agency’s latest Short-Term Energy Outlook (STEO), released Jan. 14, coal’s […]

PJM Interconnection will not run a base residual auction (BRA) until the Federal Energy Regulatory Commission (FERC) approves recalculated Minimum Offer Price Rule (MOPR) floor prices for new and existing resources as directed by the federal entity’s ground-shaking Dec. 19 capacity market order. But when that will occur is still highly uncertain. In a presentation […]

The Arkansas Public Service Commission has approved a plan to retire the Dolet Hills power plant, a coal-fired unit in Mansfield, Louisiana that serves part of the state. The decision, reached in December and announced Jan. 8 by the Sierra Club,  came as part of a settlement agreement in a recently concluded Arkansas rate review, […]

In this webinar we will cover the typical limiting factors of gas turbine components and how they can be repaired. We will cover the steps used in implementing a life time extension and will show some case studies. Some examples of how new parts are redesigned with features that make them more robust will also be covered.

This webinar will be beneficial to the engineers and power plant personnel involved with the refurbishment and replacement of the gas turbine hot gas path components.

Welcome to the next level of performance and efficiency: The Siemens combined cycle solution merges best-in-class gas turbine technology with industry leading steam turbines. With the development of the HL-class, Siemens continues its leadership in large air-cooled gas turbines by pushing plant efficiencies beyond 63%, with a clear roadmap to even higher values. The focus of the webinar will be the SCC-9000HL power plant for the 60Hz markets, which provide a 1×1 combined cycle power output of ~577 MW. The HL-class is designed for highest operational reliability and flexibility to fulfill the requirements of base load units while also being a perfect fit for flexible applications. This makes the HL-class turbines a versatile solution for operators who anticipate energy systems with a rapidly increasing share of fluctuating production by renewables.
