EDC says Tongonan fully restored by Q1

Energy Development Corp. said Thursday it expects to bring the 112.5-megawatt Tongonan geothermal power plant in Tongonan, Leyte to full running capacity by the first quarter of next year after suffering damage from super typhoon Yolanda.

The Tongonan geothermal plant, owned by EDC, forms part of the 650-MW Leyte power stations that were severely damaged by Yolanda.

EDC acquired the operations of the Tongonan station, along with the 192.5-MW Palinpinon geothermal power plants, in a government auction in 2009.

“EDC is able to accelerate the start of reliability runs and return to service of the three generating units of the 112.5-MW Tongonan Power Plant in coordination with National Grid Corporation of the Philippines,” the company said in a disclosure to the Philippine Stock Exchange.

“It is foreseen that this will happen on a successive basis, beginning with the first unit today, followed by the last two units up to the first quarter of 2014,” it added.

EDC said its technical team identified the cooling tower restoration as a critical activity, requiring replacement of fan blade assemblies, shrouds, fills and the main structures of the cooling towers themselves.

“Given the  existing spares available from all of EDC’s warehouse facilities and the available stocks and earliest deliveries from established supply chain partners, the less extensive requirements of the Tongonan plant’s cooling tower restoration was met ahead,” EDC said.

EDC earlier reported that the cooling towers of the Malitbog (232 MW), Tongonan (112.5  MW) and Mahanagdong (180 MW) power plants became “inoperable” due to significant damage sustained from typhoon Yolanda.

The company said in addition, part of the cooling system of the Upper Mahiao (130 MW) was also damaged. Cooling towers prevent turbines from overheating. The control systems of Tongonan, Mahanagdong and Upper Mahiao also sustained water damage.
