Project Overview

GNPower Dinginin (GNPD) is a 1,450 MW supercritical coal-fired plant in Mariveles, Bataan, Philippines, comprising two 725 MW units commissioned in 2022. As the largest coal-fired plant in the country, GNPD supplies approximately 7% of the combined Luzon and Visayas grid energy demand. Both units are equipped with flue-gas desulfurization (FGD), enabling fuel flexibility across coal grades while meeting emissions requirements.

Why This Project Matters For Procurement Diligence

On GNPD, Smartland's senior advisor was embedded directly within the project site team overseeing the EPC contractor - tasked with monitoring site-team performance, ensuring accurate reporting of site activities, supporting problem troubleshooting, and verifying that contract requirements were met. The off-taker (the Philippine grid) maintained no site presence, and the project's partial owner held no role in day-to-day site management, so disciplined, on-the-ground oversight of execution and reporting was essential. The plant was constructed and commissioned during the height of the COVID-19 pandemic, which compounded the logistical and scheduling challenges of a build at this scale.

Specific responsibilities executed on this engagement included:

  1. Construction monitoring - on-site evaluations against Prudent Utility Practices, with particular attention given the contractor profile (Chinese contractor team)
  2. Project approvals - review and comment on engineering, vendor, and design submittals
  3. Change-order evaluations - common-sense review of contractor change-order requests, with informed escalation to ownership
  4. Payment-request review - verification against direct site observation before owner approval
  5. Vendor-payment support - including modified payment plans where necessary to preserve vendor relationships and community relations
  6. Site monitoring with commercial impact tracking - financial, legal, and procurement support coordinated with the Coal BU
  7. Legal-claim handling - including notices of lien, with escalation paths for major claims requiring board approval
  8. Document and correspondence management - including document control system (Syncplicity) administration
  9. O&M manual review as required
  10. Onshore construction management assistance during commissioning phases
  11. Owner's Representative nomination and confirmation for ongoing roles
  12. Construction reporting - review and comment on monthly construction reports
  13. Document-control system access management
  14. Site-access and documentation coordination with GNPD ownership

The procurement-relevant signal: this is the same kind of independent oversight discipline a sophisticated off-taker today wants their development partner to have lived through. When Smartland delivers a BTM project under an offtake, we have the muscle memory of having sat on the other side of the table on a 1,450 MW asset.
