The sale of TransCo's subtransmission assets involves some 131 sale packages covering 107 interested DUs, mostly electric cooperatives. In cases where more than one DU is connected to a transmission line, the connected and qualified DUs must form a consortium to buy and thereafter operate the asset. These subtransmission assets include about 6,200 circuit kilometers (ckt) comprising mostly 69kV transmission lines and 1,600 MVA of substation capacity. The cost of these assets is placed at about PhP7.6 billion (based on December 31, 2007 net book values).
As of October 31, 2010, TransCo had divested itself of PhP3.55 billion (69 sale packages) worth of subtransmission assets including 325 MVA transformers in favor of 57 DUs. Included in the sale packages are 40 Lease Purchase Agreements with 32 cooperatives under concessional terms amounting to about PhP2.4 billion. The balance of over PhP1.150 billion represents sales to private distribution utilities. Thirty-three sale contracts have been approved by the ERC amounting to PhP1.75 billion as of October 31, 2010.
