Executive Summary
The 2010 – 2019 Distribution Development Plan (DDP) update is the 7th publication since the passage of the Electric Power Industry Reform Act of 2001 (EPIRA). In the planning period 2010-2019, the Distribution Utilities (DUs) expect an increase in peak demand of 4,258 MW from 8,856 MW in 2009 to 13,113 MW in 2019, representing an average growth of 4.0% annually. Luzon is projected to have a 3.9% annual average growth rate in peak demand, from 7,057 MW in 2010 to 9,553 MW in 2019. Visayas and Mindanao will have a higher growth rate at 4.5% and 4.4% respectively from 1,204 MW in 2010 to 1,737 MW in 2019 for Visayas, and from 1,250 MW in 2010 to 1,823 MW in 2019 for Mindanao.
In terms of aggregated energy requirements of DUs in Luzon, it is projected to grow at an annual average growth rate of 4.0%, equivalent to 16,023 GWh, over the ten-year planning period, from 40,504 GWh in 2010 to 56,527 GWh in 2019. Visayas DUs is seen to register an annual average growth rate of 4.7% or 3,132 GWh, from 6,354 GWh in 2010 to 9,486 GWh in 2019, Mindanao DUs will register a 4.4% annual average growth rate or 3,114 GWh, from 7,019 GWh in 2010 to 10,133 GWh in 2019.
Likewise, the DUs are projecting a substantial increase in the number of customers by 2019:Luzon at 12.122 million; Visayas at 3.593 million; and Mindanao at 3.267 million. These translate to an annual average growth rate of 3.01% in Luzon, 4.09% in Visayas, and 4.02% in Mindanao energy sales, respectively. Increase of number of DU’s customer is particular to the increase by 5,001,088 residential customers of the expected 5,362,752 DU customers over the planning period. Overall, from total of 13,619,247 customers in 2009, DUs are projecting a total of 18,979,999 customers by 2019.
To meet the projected increase in energy requirements over the planning horizon, an estimated 26,565 ckt-km of lines are programmed for rehabilitation and/or upgrading, 17,630 ckt-km of lines are for construction, and an additional 5,232 MVA substation capacity will be constructed. These will have corresponding investment requirements amounting to PhP 68.1 billion, broken down into: PhP 18.4 billion for electrification projects, PhP 17.2 billion for construction new lines, PhP 11.1 billion for additional substation capacity, and PhP 21.3 billion for rehabilitation of distribution lines.
