Renewable energy developer Sun Energy is strengthening its role in Indonesia’s industrial decarbonization push by rolling out a suite of green mining solutions aimed at reducing emissions, improving energy efficiency and advancing sustainable practices in the extractive sector.

The company said its strategy is grounded in the expansion of solar power systems tailored for mining operations, many of which operate in remote, off-grid regions and supported by an ecosystem of technologies across the Sun Group.

Sun Energy CEO E. Jefferson Kuesar said the company is deploying an integrated approach combining solar photovoltaic (PV) plants with Battery Energy Storage Systems (BESS) to ensure reliable, round-the-clock power for mining sites.

“Our strategy is carried out through the integration of solar power with energy storage and collaboration across Sun Group business units,” Jefferson said as quoted in a statement on Wednesday, November 19, 2025.

Within this ecosystem, Sun Terra strengthens energy storage capabilities, Sun Mobility accelerates mine fleet electrification with electric vehicles (EVs), while NIRA provides sustainable water management solutions. To date, Sun Energy has implemented clean-energy technologies at more than 15 mining locations across Indonesia.

The Solar Power Plant (PLTS)-BESS system is designed to stabilize power supply in areas without grid access, reduce fuel consumption, and lower logistical energy costs one of the biggest operational burdens for remote mines. Excess solar energy captured during the day can be stored and used at night, enabling more efficient and cost-effective mining operations.

The company has also introduced Solar PV Roll Up, a mobile solar technology that can be quickly installed, dismantled, and transported between sites. The innovation is well-suited for exploration stages or mines with shifting operational zones.

The system is expected to help mining firms cut emissions, lower fuel dependency, and maintain continuous operations in remote areas.

Beyond energy systems, Sun Energy is expanding decarbonization efforts through Sun Mobility, which provides Fleet-as-a-Service (FaaS) that integrates electric vehicles with charging infrastructure. EV-based fleets have been shown to reduce exhaust emissions while cutting maintenance and fuel costs.

“By the end of 2025, Sun Mobility will begin operating dozens of electric vehicles for a major mining company in Indonesia as part of our green-mining initiative,” Jefferson said.

Meanwhile, Sun Group unit NIRA is supporting water-related sustainability through ultrafiltration and reverse-osmosis technologies aimed at treating and recycling process water. One of its deployments at PT Berau Coal has helped reduce freshwater intake while maintaining environmental performance in mining areas.

With these integrated technologies, Sun Energy aims to accelerate Indonesia’s transition toward greener, more efficient and sustainable mining operations a sector that remains central to the country’s industrial development but also a major contributor to emissions.

The company says its green mining platform is intended to help the industry reduce environmental impacts while improving operational resilience amid tightening global sustainability standards.
