The collaboration between engineering contractors (e.g., PT. Prima Indojaya Mandiri, PT. Inti Karya Persada Teknik) and national stakeholders like PT. PLN has played a critical role in strengthening power facilities across Berau and Malinau. The scale of these public-private collaborations not only boosts infrastructure but also contributes to job creation, regional upskilling, and more stable electricity for remote regions in East Kalimantan. These projects echo the broader mission of equal energy distribution across the archipelago.
