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.
Singapore has ruled out nuclear energy as an alternative for the near future despite concerns over energy security. The city-state is heavily reliant on imported natural gas for power generation and policy makers had mulled the nuclear option to complement its energy mix.
Turkey keeps getting the attention of players from every corner of the natural gas-based power generation industry, even though the government complains about the country's dependency on natural gas and pledges to bring it down from today's 70% market share.
Louisville Gas & Electric (LG&E) has accelerated works to commission a replacement 640-MW gas-fired plant and the utility said it will consequentially retire three units at the 536 MW Cane Run coal plant in Kentucky eight months earlier than initially planned.
Britain is preparing to make a 'dash for gas generation' which may pove to be the more affordable option than renewables.
"Following the government's change in policy direction, it is now time and money that will determine whether a power plant, equipped with viable Carbon Capture and Storage (CCS) technology, will be in operation by 2020," says Howard Rogers, Director, Gas Programme, Oxford Institute for Energy Studies (OIES).
To break the vicious cycle of high gas prices leading to demand destruction, no downstream investment and gas generation being displaced coal, analysts at the French investment bank Société Générale recommend to adapt pricing to the source of demand.
