MANILA, Philippines -  Energy Development Corp. on Friday said one of its Bacon-Manito (BacMan) geothermal plants was shut down due to "vibration issues." 

In a disclosure, EDC said its operations at its Bacman unit 2, which has been operating since February 5, have been halted due to vibration issues.

The company said initial inspection conducted on February 28 showed a turbine blade was sheared off causing damage to the unit. 

"We recognize the serious nature of this new setback to Bacman Unit 2. We will do everything to determine the cause of this problem, and to ensure that this is completely resolved at the soonest time possible,” EDC President Richard Tantoco said in a statemnt. 

While Bacman unit 1 did not experience similar problems, EDC has also temporarily suspended its operations for inspection. EDC did not provide other details. 

EDC, the country's leading producer of geothermal energy and an affiliate of First Gen Corp., had recently resumed operations of the BacMan plants in Bicol. BacMan has two 55-MW turbines, while BacMan 2 has two 20MW geothermal units. EDC acquired the plants from the government in 2010.

EDC reported its consolidated recurring net income surged 89% to P9.89 billion in 2012 from P5.24 billion in 2011.
