The GT26 and GT24 gas turbines offer greater flexibility to suit today's dynamic power markets like the UK. Improved fuel flexibility, flexible operation modes, and unique low load operation capability are achieved through sequential combustion, says Alexander Bill, service manager at Alstom's Power Division.

Deployment of carbon capture storage (CCS) technology will allow for more coal and gas to be used than without CCS, Sean McCoy, analyst at the International Energy Agency (IEA) told Gas to Power Journal.

"More than two thirds of today's fossil fuel reserves would have to remain un-burnt and in the ground in the absence of CCS," he said referring to the IEA's World Energy Outlook 2012.

Norwegian oil and gas major Statoil has selected Siemens' PostCap process for phase-3 in the technology qualification program for the carbon capture and storage (CCS) plant at the combined-heat and power plant at the refinery in Mongstad. The final phase of the qualification process will come to an end in April 2013.

With abundant availability of natural gas from conventional and shale resources in the US, there is no economic incentive to develop gas hydrate resources, as a further source of gas supply for power plants and industrial use, says the US Department of Energy (EIA).

The F-class turbine fleet is now mature and of the right size to interest third party part and service providers, says Intergen manager for project development engineering, Kevin Baker. Intergen has terminated a maintenance support contract with an original equipment manufacturer (OEM) and tendered for a third party provider to service one of its power plants.

Carbon capture reduces the efficiency of the combined-cycle gas turbine power plant (CCGT) by 11%-point, a study by Sari Siitonen, Gasum Oy and Leena Pirhonen ÅF-Consult shows. The study analyses how the integration of pre-combustion carbon capture technology in the gas-fired combined heat and power (CHP) plant affects the efficiency, power-to-heat ratio, CO2 emissions and costs of the power plant.

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.

News in Brief

OGUK responds to Labour Party Manifesto

Nov 21 – The UK North Sea industry association Oil & Gas UK (OGUK) has warned of an investment hiatus in reaction to Labour’s pledge to introduce a windfall tax on oil and gas companies, if it wins the General Election on December 12. Responding to this, OGUK said any increase in tax rates would drive investors away, damage the competitiveness of the UK’s offshore oil and gas industry, and could potentially increase the country’s reliance on imports. OGUK underlined it has put in place a ‘Roadmap 2035 a blueprint for net zero emission’ and is investing in technology to achieve this goal.

France, Germany and UK led on demand-side flexibility

Nov 21 – France, Germany and the UK are leading on demand-side flexibility (DSF) and grid-integration of decentralized energy sources while Sweden, Spain and Portugal are lagging behind the rest of Europe, the consultancy Delta-EE and SmartEN finds. Areas covered by their new DSF monitoring tool include availability and accessibility of demand-side response, and its monetization across the gas value chain.

AI predicts peak in power use

Nov 20 – ABB and Verdigris Technologies have developed machine-learning algorithms to predict unplanned peaks in electricity consumption and help avoid them. The Energy Forecasting app will enable users to reduce their electricity bills by reducing peak demand charges.

India’s first UHVDC link commissioned

Nov 19 – GE Grid Solutions has commissioned Pole-3 - the ultra high-voltage direct current (UHVDC) transmission line in India, capable to transmit 4,500 MW of electricity. Once completed the Champa-Kurukshetra UHVDC project will be expanded to transmit 6,000 MW of electricity at 800 kV, serving customers in the areas of Punjab, Haryana, Delhi, Uttar Pradesh.

COP25 urged to step up climate efforts

Nov 18 – The COP25 UN climate conference in Madrid is urged to enshrine greater commitments from the world's industrialised nations to curb their greenhouse gas emissions. “Europe will have to play a key role in this regard,“ environment minister Svenja Schulze said, adding Germany's recently announced climate package marks a "restart" in the country's climate policy.

U.S. storage injection hits record high

Nov 14 – Near-record volumes of natural gas have been placed into storage in the United States in the current injection season. According to the U.S. Energy Information Administration (EIA), the amount of gas held in storage in 2019 surged from a relatively low value of 1,155 billion cubic feet (Bcf) at the beginning of April to 3,724 Bcf at the end of October.

SaskPower proceeds with Moose Jaw project

Nov 13 – Canadian utility SaskPower has taken a significant step towards realizing a 350 MW gas power plant at Moose Jaw. The project was first proposed in 2017, but in the Canadian federal government June last year introduced new regulations for gas generation coming online after January 1, 2021, which stalled the plans. Having completed its regulatory review, Sask Power was now granted permission to proceed from the municipality of Moose Jaw. Major Fraser Tolmie said “this $700-million investment into the city of Moose Jaw, will ensure we have base-load power in the province of Saskatchewan and to maintain our power independence.”
