Background
• The rate of self‐sufficient of energy in the Philippines is low compared with other Asian countries. Energy policies state the enhancement of energy efficiency in the Philippines.
• For years both NEA and ECs have come up with strategic initiatives that will reduce power distribution loss levels.
• NEA sought the assistance of JICA which sent the Technical Assistance Team to provide necessary support to develop technical capacity and planning abilities of ECs to reduce distribution system losses.

ECs’ Distribution Loss Ratios
Some ECs could achieve single digit loss ratio. But more could be reduced.
Counterpart Training in JapanMar.2012 & Sep.‐Dec.2012
• Participants visited the Japanese Major Manufacturers.
• Various distribution facilities in Tokyo and Shikoku were good reference to understand urban distribution system of Japan.
12
Technical Situations of Some ECs‐ From the Results of Site Surveys in 2011
• There are some;
– substations with its heavy load• CASURECOII, ISELCOI, FLECO, etc.
– large length medium voltage lines and their single phase lines
• CASURECOII, CASURECOIV, etc.
– pole transformers with too much capacities or insufficient capacities
• most Ecs
– too much technical loss
• SORECOI, etc.
JICA provided Clamp‐on Meters targeted ECs and NEA.
13
AMDT Project
• On mid of Nov. 2012 JICA and three ECs (FLECO, ISELCO1 and PELCO2) conducted Factory Test of Amorphous Distribution Transformers at Philec factory and they received 9 AMDTseach from JICA.
• EC staff could measure the effects of amorphous with their own measurement equipments and confirm the superiority of the amorphous transformers.
14
Distribution Analysis Software
• PowerSolve
• Suitable for Segregation of Distribution System Losses
• SynerGEE
• Mapping image, detailed results of loss causing locations and easy to find out loss reduction options
JICA provided targeted ECsand NEA with SynerGEE and its training course.

Summary and Recommendation
•Utilization of Manual and Distribution Analysis Software
•Upgrading Medium Voltage to 23kV
•Application of Amorphous Transformers
20
Utilization of Manual and Distribution Analysis Software
• The System Loss Reduction Manual has been prepared and quantitative evaluation of system loss using the distribution analysis software would be supported.
• The institutional promotion system of Manual should be established by NEA and ECs to become able to implement its recommendation and revise them in case of change in the situations.
• Database should be maintained to promote to making system models on the distribution analysis software.
• We recommend that many loss reduction plans should be looked into that are able to yield benefits far exceeding costs for its measures by utilization of this Manual.
21
Upgrading Medium Voltage to 23kV
• The voltage upgrading of medium voltage systems was preliminary studied and its technical guideline was recommended in the Manual.
• It can be found out that in some cases the application of 23 kV may be superior to 13.2 kV from the economic point of view.
• We recommend that the detailed studies should be implemented for the evaluation of the candidate sites of 23 kV upgrading regarding their feasibility, costs and benefits brought by loss reduction.

• The amorphous transformer pilot project has been executed. Its effects on loss reduction could be confirmed.
• We recommend that the installation of amorphous transformers should be promoted in all the ECs with their adequate economic evaluation.
