PNOC EC is the holder of COC 122 which straddles portions of the city of Cauayan and the municipalities of Naguilian and Benito Soliven in Isabela. The project involves putting up either a 30MW, 50MW or 100MW power plant simultaneous with coal mining operations from where the lignite (low rank) coal will be sourced. Meanwhile, COC 141 is projected to augment the production of COC 122 in the long term.

In 2008, PNOC EC commenced the technical and economic reassessment of the project. The environmental compliance process was also started in the same year with the bidding out of the Environmental Impact Assessment (EIA) consultancy. PNOC EC has also revived its coordination work with the local government units of Isabela through information education communication (IEC) campaigns and social development programs implementation (outreach programs, trainings and seminars).
