Natural gas has become the preferred fuel for electricity generation worldwide because of its environmental appeal, lower capital cost, shorter gestation period, higher efficiency and the modular technology (International Energy Agency (IEA), 1995) that challenges ‘the bigger the beautiful’ notion of the past. This trend has started with the ‘dash for gas’ in the English and Wales system after liberalization of the electricity market and has been followed in many other jurisdictions. Yet, a high share of natural gas in power generation could raise issues of security of supply and as natural gas and electricity converge (International Energy Agency (IEA), 2004), a country could become economically vulnerable.
