Indonesia's 2 Green Energy Priorities: Biodiesel & 100 GW Solar

JAKARTA — Indonesia is betting on two big moves to accelerate its shift away from fossil fuels: a more aggressive mandatory biodiesel program and a 100-gigawatt solar power buildout. Together, these programs form the backbone of the government’s green energy push — and they signal just how seriously officials are taking the country’s long-term energy security.

The Ministry of Energy and Mineral Resources (ESDM) has already pushed the national new and renewable energy (NRE) mix to 18.3%, clearing the 17–21% target set in its current Strategic Plan. That’s a meaningful milestone. But officials are quick to point out that beating a near-term benchmark is very different from completing an energy transition.

Biodiesel: The Quiet Giant of Indonesia’s Energy Mix

Ask most people what’s driving Indonesia’s renewable energy figures, and they’ll probably say solar or hydropower. The real answer, for now, is biodiesel. Specifically, Fatty Acid Methyl Ester — FAME — which alone contributes 5.38 percentage points to the national energy mix.

“Biodiesel contributes 5.38% to the national energy mix,” said Eniya Listiani Dewi, Director General of New, Renewable Energy and Energy Conservation at the Ministry of ESDM, speaking at the Energy Forum hosted by CNBC Indonesia in Jakarta on Tuesday, June 30, 2026.

That number didn’t happen by accident. The government’s mandatory biodiesel policy — formalized under Ministry of Energy Regulation No. 4 of 2025 — has been systematically ramping up the share of palm-oil-derived biodiesel blended into diesel fuel. The program works precisely because it’s compulsory: fuel distributors must meet blend targets, which creates steady, predictable demand for domestic biodiesel producers.

The next phase will push those targets further. How far and how fast is still being finalized, but the direction is clear: more biodiesel, not less.

On the electricity side, hydropower remains the biggest contributor among power-generating sources, followed by biomass. But neither of those sectors holds the same explosive growth potential as solar — which brings us to the government’s second major bet.

100 Gigawatts of Solar: Ambitious, Necessary, and Complicated

One hundred gigawatts. That figure — the government’s solar power target — sounds almost abstract until you put it in context. Indonesia’s total installed power generation capacity today sits at roughly 90 GW across all sources. The government wants to add 100 GW of solar alone.

“Our current strategy focuses on two big issues: biodiesel and 100 gigawatts of solar power. We want to push both to increase the energy mix,” Eniya said.

The rationale is hard to argue with. Indonesia straddles the equator, receiving some of the most consistent solar irradiation on the planet. Rooftops, reservoirs, degraded land — there’s no shortage of potential installation sites. And as global solar panel prices continue to fall, the economics are improving every year.

Reaching 100 GW, though, won’t be straightforward. It requires massive capital investment, grid infrastructure that can absorb intermittent generation, and land — lots of it. Transmission lines need to connect remote solar farms to population centers. Battery storage or other balancing solutions are needed for when the sun isn’t shining. These are solvable problems, but they take time, coordination, and sustained political will.

Electrification: Rounding Out the Strategy

Beyond biodiesel and solar, the government is simultaneously pushing electrification across multiple sectors. That means promoting electric cooking stoves as an alternative to the subsidized LPG that currently dominates Indonesian households — and accelerating the conversion of gasoline and diesel vehicles to electric ones.

The logic is straightforward. Even if Indonesia generates more power from clean sources, that benefit is diluted if households and vehicles keep burning fossil fuels directly. Electrification shifts final energy consumption onto the grid, where decarbonization can happen at scale through cleaner generation.

It’s a systems-level approach: clean generation on one end, clean consumption on the other, with better infrastructure connecting the two.

Why This Matters Beyond the Energy Sector

Indonesia is home to more than 270 million people. Keeping the lights on — affordably and reliably — is a prerequisite for economic development. But the current energy model carries real risks. Heavy reliance on imported fossil fuels exposes the economy to global price swings. Coal and oil revenues, while significant today, face long-term demand uncertainty as major trading partners accelerate their own energy transitions.

A stronger renewable energy base changes that calculus. Domestically produced biodiesel reduces the fuel import bill. Solar power, once installed, has near-zero fuel cost. Both improve energy security in ways that imported fossil fuels cannot.

Indonesia is also under growing international pressure to demonstrate credible climate action. The country has committed to reaching net-zero emissions — and its credibility on that commitment will partly be judged by whether programs like these actually deliver. Renewable energy investment also creates domestic jobs in manufacturing, installation, and maintenance, sectors that could absorb a significant portion of the workforce in the coming decade.

The Hard Part Still Lies Ahead

Hitting 18.3% in the energy mix is worth acknowledging. But the targets ahead are steeper, and the easy gains have largely been taken. Scaling biodiesel further requires careful management: palm oil is also a food commodity, and unchecked expansion of plantations raises deforestation and food-security concerns that the government cannot ignore.

The 100 GW solar target will demand unprecedented inter-agency coordination, private sector participation at scale, and financing mechanisms that work for both large utility projects and smaller distributed installations. Neither challenge is insurmountable — but neither will resolve itself.

What happens over the next three to five years will largely determine whether Indonesia’s energy transition is real or merely aspirational. The strategy is on the table. Execution is everything.

3 Key Takeaways

• Indonesia’s renewable energy mix has reached 18.3%, with biodiesel (FAME) alone accounting for 5.38 percentage points — the single largest contributor.
• The government’s two main acceleration levers are expanding mandatory biodiesel blending and fast-tracking 100 GW of new solar power capacity.
• Electrification of cooking and transport complements the generation-side strategy, aiming to shift end-use consumption away from fossil fuels at the household and vehicle level.

FAQ

What is Indonesia’s current renewable energy mix?
As of mid-2026, Indonesia’s new and renewable energy mix stands at 18.3% of total national energy consumption, above the 17–21% target in the current Strategic Plan.

Why is biodiesel such a big part of the mix?
Indonesia has a large domestic palm oil industry and a well-established mandatory blending policy. This makes biodiesel relatively easy to scale compared to building new power plants.

Is 100 GW of solar realistic?
Indonesia has the geographic and climatic conditions for it, but reaching that scale requires major grid investment, land allocation, and private financing — none of which are guaranteed without sustained policy support.
