Vattenfall Wärme Berlin, district heating provider and part of the Swedish utility Vattenfall, is utilizing the world’s first MXL2 upgrade for GE’s GT13E2 gas turbines that uses components manufactured through additive technology. The first-stage turbine vanes and heat shields are 3D-printed in GE facilities in Birr, Switzerland, and Greenville, South Carolina.
Cheap gas supply spurs construction of new gas power stations in the United States, with CCGT additions anticipated to reach 9% after topping 8.8% last year. According to EIA figures, over 7.5 GW came of new gas generating capacity went online last year as planned, and 2.6 GW were delayed until 2018.
Flexible gas-fired “peaker” plants, together with energy storage, will bolster the intermittency of solar and wind power for years to come, according to Bloomberg New Energy Finance (BNEF). Battery storage is forecast to see surge in capacity by a factor of more than 160 times by 2050.
Following substantial investment in new capacity, Gazprom’s power generation strategy through to 2027 is focussing on upgrades as well as decommissioning on economically unviable capacity. Construction of the Grozny thermal power plant is slated to be finished before the end of 2019.
Eager to advance energy savings, U.S. electric utilities have spent over $3.6 billion on energy efficiency customer incentives in 2016, or an average of $24 per customer. According to an EIA survey, the top spent on efficiency savings was in Massachusetts, with $128 per customer.
Come June 26, General Electric will lose its listing in the Dow Jones Industrial Average after more than a century, reflecting GE’s difficulties to win new business and a slump in the company’s share price. GE executives said drooping out of the Dow would not change the company’s commitment to create a “stronger, simpler” enterprise.
Only large scale and intelligent energy storage can solve the issue of variable renewable electricity generation. There is little political will for a fresh wave of subsidies for storage – as there was for renewables – hence a carefully crafted market design is needed to incentivises flexibility and storage, says Patrick Clerens, Secretary General at the European Association for Storage of Energy (EASE).
Finland’s technology group Wärtsilä has launched an integrated solar PV and energy storage to deliver a true “renewables as baseload” solution that increases resilience and efficiencies. The adaptable Wärtsilä Hybrid Solar can be supported by a power producer’s existing grid infrastructure.
French utility Engie has sold its shareholding in Thailand’s Glow Energy to the PTT unit Global Power Synergy for net proceeds of €2.6 billion. With the disposal, Engie will no longer operate any coal-fired assets in Asia-Pacific and reduces its installed coal power capacity by 14% globally.
Dismissing news about a possible sale of Siemens Power&Gas (PG) business unit, CEO Joe Kaeser said he wanted to improve the unit’s performance although this doesn’t exclude the possibility of outsourcing, or sale, at a later stage. A Siemens employee familiar with the matter told Gas to Power Journal there are some strategic considerations about how to slowly dismantle the group.
First fire of Toshiba’s 50 MW(th) commercial-scale combustor has been carried out at NET Power’s oxy-combustion CO2 power-cycle demonstration plant in La Porte, Texas. Testing uses CO2 working fluid to produce low-cost electricity while virtually eliminating emissions of nitrogen oxides (NOx) and other pollutants.
RWG (Repair & Overhauls) Ltd, a Siemens and Wood Company, has been appointed for new assembly and testing of Siemens SGT-A05 (KB7 HE) gas turbines. The Houston-based facility of RWE will handle all aspects of the new-build programme including sub-assembly, dynamic balance, engine assembly and factory acceptance testing.
Global gas trade expanded last year by 63 billion cubic metres, or 6.2%, with growth in LNG outpacing growth in pipeline trading, according to the latest BP Statistical Review of World Energy. The apparent absence of a glut shows, according to analysts, that any surplus LNG resulted in bouts of unsustainably low prices rather than a build-up of idle capacity.
Today, Electrify Europe – the world’s first event dedicated to the convergence between power generation and distribution sectors – is getting underway in Vienna, Austria. Digitalization, decarbonization, decentralization and electrification are the megatrends that are critically examined in various conference panels and on the exhibition floor.
Ansaldo Energia and Leonardo – one of the top ten players in aerospace, defence and security – are setting up the "Start 4.0 Competence Centre for the Security and Optimisation of critical Infrastructures" in Liguria, Italy. Their mission is to identify adequate solutions through experiments and validate methodological approaches to map risk and protect infrastructure, notably power plants.
