Qatar plans to invest over $5 billion by the end of next year to boost its power and potable water production capacity, the head of the country\'s state utility said on Tuesday. The gas-exporting country already has 30 percent more power generation capacity than it needs, allowing it to sell some to neighbours like Kuwait and Bahrain, with new projects offering the potential for more exports in a few years. \"Qatar will spend $2.4 billion this year and $2.8 billion in 2013 to increase power and water capacity,\" Abdulsattar al-Rasheed, chief executive of Qatar Electricity & Water Company told a conference. New projects include a 2,250 megawatt (MW) power plant, two desalination plants with a total capacity of 194 million gallons per day, and large water reservoirs. Qatari electricity demand growth averaged 11.4 percent in the five years to 2011, but fell to 8.8 percent last year as the number of large new power consuming project starts slowed. Qatar spent $2.2 billion in 2010 and $1.7 billion in 2011 in the power and water sector, he said. Qatar is investing billions of dollars in new infrastructure as it prepares to host the 2022 World Cup soccer tournament.
