| Abstract | The most cost efective way to develop additional generating capacity is by re-powering of existing geothermal paver plants uiilizing untapped, and othenviie wasted, geothermal energy without any additional drilling or resource development costs, and open with environmental benefits. This presentation deals with the case histories of severai such applications: (a) the 9. IiUW exhaust steam recovery binary power plant at Svartsengi in Iceland; (b) the 6.4 MW brine recovery binary power plant at Kawerau in Nav Zealand; (e) the 17 iUW excess pressure inlet steam topping turbine at Tongonan in the Philippines; (4 the 19 MW excess steam topping turbines at Mahanaghng A&B in the Philippines, and (e) the 13 excess steam condensing steam turbine bottoming unit at Malitbog in the Philippines. These re-power plants have added a total of 64 MW of geothermal power and improved environmental and power plant operating conditions, without q a&tional well field costs. With geothermal paver plant developers and operators vev concerned about competitive costs, increasing plant output by repowering without additional wll fwld development is a highly desirable and cost dective option. |
