Dear Ms. Encarnacion:

This is to inform the Exchange that the 20MW Unit 3 of the Bac-Man Geothermal Power Plant Complex of Bac-Man Geothermal, Inc. (BGI), a wholly-owned subsidiary of the Energy Development Corporation (EDC), auto-tripped on Thursday, March 5,
2015 at 0737H, which by initial indication was due to a minor lube oil leak.
The inspection is now focused on possible effects to turbine and generator bearings and other components and on the repairs as may be necessary, preparatory to the restarting of the unit. Spare parts are available on site and the partner-contractors have been mobilized.
The unit is expected to be back in service in time for the peak energy demand in the summer months.
During the shutdown, BGI will take the opportunity to initiate planned facility upgrades. We shall apprise the Exchange of further developments.
