Enel has taken action to increase the competitiveness of its fleet of combined cycle gas turbine (CCGT) power plants, as the operator needs to come to terms with reduced operating hours and increases number of plant start-ups and shut-downs to balance renewable energy supply.

Future gas turbine research and development (R&D) needs to focus on a 'big is beautiful' approach to developing smaller, flexible units that can run efficiently at part-load, OEM representatives from Alstom, GE, Mitsubishi HI, Siemens and Pratt & Whitney Power Systems agreed at a conference in Brussels today.

Singapore is building three new large combined cycle plants to cater for the city state's growing electricity demand.

"The selection of combined cycle plants based on GT26 advanced gas turbines for all three of these projects indicates the importance of high plant flexibility while maintaining high efficiency and low emissions in many of today's electricity markets," says Pascal Radue, regional vice president, Alstom Gas Business, Asia.

GE will supply eight gas turbine-generators for the expansion of Saudi Electricity Company's (SEC) Riyadh Power Plant 12 (PP12). Once operational in 2015, the combined-cycle plant will be the first application of GE's 7F-5 series gas turbine technology in Saudi Arabia, adding  nearly 2,000 megawatts of electricity to help  meet the Kingdom's future energy demand.

RWE's decision as to which gas turbine vendor to use for its newly opened Pembroke Power Station has been largely driven by Alstom's service agreement, according to Andy Smith, project development manager at RWE.
"In the UK, the market for building new combined-cycle plants is EPC-based and we were therefore exposed to the equipment choices that the different turbine manufacturers have on offer," he told Gas to Power Journal at a conference organised by the publication in London.

Rolls-Royce has launched the retrofit upgrade RB211-Gzero that can provide existing users of industrial RB211 aeroderivative gas turbine engines with a nominal power increase of 10 percent, depending on ambient temperature and engine type.

Toshiba Corp and GE have joined forces to sell a combined cycle power generation system that integrates GE's advanced 7F 7-series gas turbine and GE's 60Hz gas turbine with Toshiba's high efficiency steam turbines and generators.

GE has launched its new FlexEfficiency 60 power generation portfolio, saying the solution was "engineered to harness natural gas" while taking into account the rising market share of renewable energy.

ExxonMobil is adding a new cogeneration plant in Singapore as part of the expansion of its petrochemical complex in Jurong. Located on a man-made island in the south-west of Singapore, the new facility is part of an industrial and power generation hub.

Kawasaki Heavy Industries (KHI) has completed of the development of a new 30 MW gas turbine – the Kawasaki L30A. Start-up of the first L30A package, installed at a plant in Japan, is due this October.

Aggreko, a leading provider of temporary power generation services, has opened its first service centre in Walvis Bay, Namibia, to meet to power demand of the country's rapidly growing mining industry. Located next to the Port of Walvis Bay, the facility is also well positioned to supply backup power generation to Namibia's shipping and fishing industries.

Alstom has developed a MXL2 upgrade for GT26 gas turbines, offering power plant operators to adapt production hours of their plants to fluctuating demand and to significantly extend inspection intervals and increase availability – key features in markets with a large share of intermittent wind generation such as Spain, says Leone Tessarini, product manager at Alstom's gas turbine services.

News in Brief

Growth in turbine air filtration tops 3%

July 22 – The turbine air filtration market is expected to grow 3.27% annually from $1.92 billion in 2020 to reach $2.29 billion in 2026. Demand from the oil & gas industry and electric utilities had plunged during the corona crisis and subsequent economic downturn, but the latest trend towards clean energy is driving robust growth for turbine air filtration which can be widely and easily applied in the power sector.

US oil exports stay high

July 21 – Despite volatile prices, U.S. crude oil exports reached a record high in 2020 and remained strong this year, averaging 3.51 million barrels per day (b/d). Expanded ports at Houston and Corpus Christi allow for oil to be exported from the Permian Basin and Eagle Ford Basin.

CVEC to be converted to hydrogen

July 20 – Cricket Valley Energy Center (CVEC) is taking steps to run the  combined-cycle plants on hydrogen. Works to convert the plant will be carried out by GE and are scheduled to start in late 2022. One of three GE 7F.05 gas turbines at CVEC will be introduced to a 5% hydrogen blend with natural gas.

MAN ETES labelled solar impulse efficient

July 16 – MAN Electro-Thermal Energy Storage (ETES) was attributed the “Solar Impulse Efficient Solution” label by independent auditors. In January, the German manufacturer supplied to ETES heat pumps to DIN Forsyning for a heat and power plant in the Danish port city Esbjerg.

Electricity sales to US industry rebounds

July 14 – Economic recovery has caused a 5.1% rise electricity sales to US industry this year, dwarfing 2.8% more retail sales and a 2.1% rise in the commercial sector as many office workers continue working from home. The US Energy Information Administration’s (EIA) acting administrator, Steve Nalley, called the rebound in electricity sales to industry a “strong sign of rising levels of economic output as the Covid-19 pandemic recedes.”

Solar PV to triple in Asia by 2030

July 13 – Asia Pacific solar photovoltaic capacity could triple to 1,500 gigawatts (GW) by 2030. According to Wood Mackenzie estimates, China will add 619 GW of mainly utility-scale capacity while most other nations in Asia prefers distributed solar due to land constraints. Solar PV tends to be backed up by flexible gas gensets and energy storage, forming hybrid power units.

Kinder Morgan closes on Stagecoach assets

July 12 – US energy infrastructure major Kinder Morgan has closed its acquisition of Stagecoach Gas Services. The deal include 4 gas storage facilities with a 41 bcf working gas capacity and a transmission network with multiple interconnects to major interstate pipelines, including Tennessee Gas Pipeline. The Stagecoach assets add to Kinder Morgan’s approximately 83,000 miles of pipelines and 144 terminals.

Dortmund cancels electrotechnik fair

July 9 – The elektrotechnik fair, planned for 29 September to 1 October 2021, will now not be taking place in Dortmund due to requests from the industry. The next trade fair for building, industrial, energy and lighting technology will now open its doors again in spring 2023.
