Chevron Corporation, a leading integrated energy company, has announced that its Australian subsidiary, Chevron Australia Pty Ltd, has reported a further offshore drilling success in the Greater Gorgon Area, one of the world's largest natural gas projects and the largest single resource natural gas project in Australia.
Centrica Energy's fleet of gas-fired plants has undergone "a massive change in operation" as flexibility is paramount to counterbalance the intermittency of renewable energy supply. The operator now runs the 230 MWe gas-fired Barry Power Station as a peaking plant in an open-cycle mode to boost operational flexibility.
China has to reform and liberalize its tight power tariff regime for gas-fired power generation to gather momentum and to attract investment in new-builds, says Gavin Thompson, principal consultant for Asia Pacific, Gas & Power at Wood Mackenzie.
"The power tariff is very flat, there is no capacity charge in peak generators and very little regional difference in power prices," Thompson told Gas to Power Journal at the sidelines of the Gas Asia Summit, held as part of the Singapore International Energy Week.
Power generation companies and industries in Singapore have committed to purchasing around 2.7 million tons per annum (mtpa) of LNG, S. Iswaran, second minister for home affairs and trade and industry said at the Asia Gas Summit. BG, appointed as the aggregator for importing the first 3 mtpa of LNG, has already achieved 90% of its franchise, he revealed.
Plans for an ASEAN power grid must proceed cautiously with one step at a time, says power analyst Sarah Fairhurst of The Lantau Group. "There are too many players trying to align too many interests," she told delegates at the Electricity Roundtable organised as part of the Singapore International Energy Week, referring to wide disparities among South-East Asian countries.
GE is showcasing its new FlexEfficiency 60 Portfolio at today's opening of GE's Energy Technology Center in Seoul. The US engineering giant said it has configured its gas-fired FlexEfficiency 60 technology to meet efficiency and operating flexibility needs of 60-hertz countries, including South Korea.
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.
The share of gas generation in India, which at present is about 10%, is expected to rise as the government steps up efforts to form a national gas grid. Provisions in the Electricity Act such as open access to transmission and distribution network, recognition of power trading as a distinct activity, flexibility accorded to captive generating plants and provision of supply in rural areas will introduce and encourage competition in the electricity sector, an analyst with India's Central Power Research Institute (CPRI) told Gas to Power Journal.
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.
The market share of natural gas in Germany's power generation mix is estimated to rise to 19%, the regulator BNA's estimated in a mid-range scenario, deemed more likely than a bullish or bearish case. The mid-range scenario anticipates installed capacity from gas-fired plants to surge from 26.5 GW in 2011 to 32.9 GW in 2023.
Unconventional gas, due to its estimated abundance, has improved energy security in the United States and started a process of gas displacing coal as the dominant power generation fuel. Europe needs to adapt regulation to foster shale gas drilling, as it needs unconventional gas to make up for depleting indigenous gas production and supply new-build gas-fired plants, says Morgan Bazilian, deputy director of the Joint Institute for Strategic Energy Analysis in Colorado, USA.
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.
South Korean energy companies, in line with the government's "Green Growth policy", have shifted towards generating more electricity from nuclear and renewable energy sources backed up by gas generation, analysts say. The government has also embarked on the liberalization of its electricity market to improve competition in the industry and encourage investment with the aim of increasing installed capacity.
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.
