The National Transmission Corporation (TransCo) is a government agency spun-off from the National Power Corporation as provided by the Electric Power Industry Reform Act (EPIRA) of 2001. Since its independent operation in March, TransCo operated and managed the country’s power transmission system linking the power plants to the electric distribution utilities nationwide. The same law mandated the privatization of TransCo through an outright sale or management concession contract.

Following the competitive public bidding in December 2007, the TransCo concession was awarded to the National Grid Corporation of the Philippines (NGCP), which eventually secured a congressional franchise to operate the transmission network. Ownership of all transmission assets however, remains with TransCo. On January 15, 2009, TransCo turned over the management and operation of its power transmission system to NGCP.

As owner of the transmission assets, TransCo’s monitors NGCP’s compliance with the terms and conditions of the Concession Agreement, divest remaining sub-transmission assets to qualified distribution utilities, and undertake contractual consultancy and other technical services for the Philippine Economic Zone Authority.
