Targeting the decentralized power market, Siemens is launching a 57 MW upgrade of its SGT-800 gas turbine at the Power-Gen Asia trade show, which, opened its doors in Bangkok today. In combined-cycle configuration, Siemens SGT-800 now achieves 163MW power output at a net efficiency of more than 58.5%.

The US Department of Energy (DoE) has announced to grant $50 million in funding for projects aimed at strengthening grid resiliency in the face of storms and cyberattacks. The lion’s share of the funds, or $33 million, is reserved for seven projects from the Modernization Laboratory Consortium (GMLC).

Pushing the limits, the new MAN 20V45/60 engine achieves a power output of 26MW at a considerably lower fuel consumption than its predecessor, the MAN 48/60. At the launch event in Augsburg on September 11, the new flagship genset was presented as “the most powerful four-stroke engine in the market.”

Silver Spring Networks and Genus Power Infrastructures, a smart meter provider in India and Southeast Asia, have agreed that the latter will integrate Silver Springs IPv6 network interface cards (NICs) into its single-phase and three-phase smart electric meters.

The energy services division of Australia’s Energy Queensland has joined forces with the energy tech firm GreenSync to create a cloud-based, load control system designed to manage extreme electricity demand during severe temperature events. Queensland treasurer Curtis Pitt called it “Australia’s biggest virtual power plant (VPP).”

Decoupling a portion of the low-voltage grid in the Allgäu region of Germany, Siemens and its partners have implemented a self-contained microgrid using only renewable power supply. Insights from this “islanded grid” in Wildpoldsried serve as a model for the “transformation to power supply supported by prosumers.”

2G Energy, manufacturer of combined heat and power (CHP) plants, has introduced a new range of low-emission systems. Ranging from 20kWe to 240kWe, the systems emit 90% nitrogen oxide (NOx) compared with standard (500mg) units.

Threats to automation equipment keep changing, so protection concepts for industrial power plants need to evolve. To address this challenge, Siemens and the International Society of Automation (ISA) have entered a global partnership to share expertise in protecting the automation environment based on the IEC 62443 standard.

Rolling blackouts are commonplace in war-torn Libya, which is why General Electric Company of Libya (GECOL) has been rebuilding the electrical infrastructure and contracted with APR Energy to bring in temporary generators to provide a rapid 450 MW boost. Some of these units are equipped with inlet fogging systems, attaining a 15% increase in output in the hot Sahara operating conditions.

Integrally geared technology provides the most efficient, space-saving and reliable solution possible. “More compact and efficient than comparable single-shaft designs, these solutions allow for a level of process control that other technologies can’t match,” Michael Andrews, Vice President of Research and Development at Atlas Copco Gas and Process told Gas to Power Journal.

Expanding their cooperation in ‘lifecycle service offerings’, ABB has granted Wärtsilä the Authorized Service Provider status for standard maintenance of ABB turbochargers installed with Wärtsilä 4-stroke engines. The new accord builds on their cooperation dating back to 2005, and will result in 25 new authorised Wärtsilä turbocharger workshops.

DILO, a German manufacturer of sulfur hexafluoride (SF6) gas handling equipment, has launched a SF6 multi-analyser that allows users to simultaneously check three key gas quality parameters- SF6 concentration, humidity and quantity of decomposition products. SF6 quality of gas insulated equipment needs be checked to determine if the gas still complies with the IEC Standard 60480 (SF6 reuse) or whether it needs purification.

To restore deteriorating output, La Paloma Generating Company (LPGC) considered an upgrade of turbine components, but found a cheaper way: "After doing a net present value analysis of the money we would have to invest and how much power we would recover, fogging turned to be really, really good in terms of dollars per kW," said Pablo Cortes Oseguera, LPGC engineering and maintenance manager. "It made a lot of sense to our owners."

Tested and validated at customer site, Siemens has reached the next level of efficiency with its HL-class – an evolution of its proven SGT-8000H technology. At Duke Energy's Lincoln County site in North Carolina, the new engine reached 63% combined cycle efficiency during testing in June 2017. Siemens’ mid-term goal is to reach 65%.

Turkey’s incumbent oil and gas pipeline operator BOTAS has awarded a contract to RWE to overhaul of three Siemens Industrial Avon aero-derivative gas generators (SGT-A20 AV). The gensets, operating at the Kirklareli compressor station, help maintain the reliability of the Turkish gas transmission network.
