PacificSun Renewables Corp., an affiliate of Sta. Clara Power and Sta. Clara International, has proposed a PHP 4.9 billion (≈ $83 million) solar power project in Paoay, Ilocos Norte. The 120.96 MW facility will occupy about 81.81 hectares across Barangays Mumulaan, Suba, and Nagbacalan, within a timberland area under Proclamation No. 150 co-managed by the Department of Environment and Natural Resources (DENR) and the provincial government. The construction phase, expected to last 12 to 18 months, includes testing and commissioning upon approval of necessary permits. DENR’s Environmental Management Bureau Region 1 has scheduled a public scoping session for October 23, 2025 to collect community feedback and assess environmental considerations for the proposed solar development.
