Tapping into the nation’s solar potential can overcome past challenges in solar development using site surveys, energy storage, and grid planning.

In Indonesia, South Sulawesi’s regional government has sought to accelerate sustainable development by expanding its renewable energy capacity, focusing on solar power — a resource-rich but underutilized sector in the province.

Previously limited by fragmented efforts, and a lack of comprehensive planning for large-scale renewable projects, their local authorities has leveraged external expertise and partnerships to overcome regulatory and infrastructure challenges.

On 19 September 2025, the region’s Regional-Owned Enterprise, PT. Sulsel Andalan Energi, announced the signing of a Memorandum of Understanding (MoU) with a Vietnam-based conglomerate with established green energy and electric vehicle operations in Southeast Asia. Together, the two entities will develop large-scale solar farms, ranging from 1 megawatt to 1 gigawatt capacities, including ground-mounted and floating solar systems. The collaboration will cover energy storage integration and grid connection planning, ensuring that projects align with both technical and regulatory requirements.

Key technical approaches include:

  • Comprehensive site surveys and feasibility studies for solar installations on land and water
  • Integration of energy storage technologies to balance supply and demand
  • Planning grid connections compatible with varying project scales
  • Leveraging insights into emerging green technology trends
  • Coordinating with local authorities on compliance and infrastructure needs

Governor Andi Sudirman Sulaiman expressed optimism about the collaboration’s potential to align with Indonesia’s national sustainability vision and catalyze regional economic growth: “This cooperation aligns with our national vision of ensuring harmony between people and the environment. Today’s MoU is just the beginning of something big,” he said.

Indonesia is considered one of the most promising renewable energy markets in South-east Asia. Given its high solar radiation, South Sulawesi is considered an ideal location for developing large-scale solar projects.
