Indonesia Plans Grid Reform to Boost Clean Energy Future

Indonesia has figured out a smarter way to pay for the power grid that will carry its clean energy future.

A new report from the Institute for Energy Economics and Financial Analysis shows the country needs $2.4 billion each year to expand its transmission network. Right now, it's only investing $1.4 billion annually. The gap isn't about lacking money or ambition. It's about how the system is structured.

Indonesia's national utility, PLN, currently finances everything from power plants to fuel purchases to transmission lines through one giant balance sheet. That means low-risk grid infrastructure gets funded the same way as volatile fuel contracts and risky generation projects.

"Despite being one of the lowest-risk segments of the power system, transmission is financed through the same corporate balance sheet that absorbs fuel price volatility and foreign exchange exposure," says Randi Bachtiar, IEEFA's Energy Finance Specialist for Indonesia. It's like paying credit card rates for a mortgage.

The solution is surprisingly straightforward. PLN would create a separate transmission company within its existing structure, keeping everything publicly owned while making the grid financially transparent to investors.

Power grids are natural monopolies with predictable, regulated income streams. When separated properly, they can borrow money at rates barely higher than government bonds. Indonesia would pay less interest and attract more capital for the massive grid expansion needed to connect solar farms and other renewable projects.

The Ripple Effect

The timing matters because Indonesia just created Danantara, a sovereign investment company that now oversees PLN. A ring-fenced transmission business would give Danantara and other institutional investors a clear, lower-risk way to fund grid expansion at the scale the country needs.

PLN has already done the hard operational work. It runs the grid through dedicated regional units with clear reliability standards. The utility also already operates through four separate subsidiaries for generation, fuel, and services, each with their own balance sheets and audited statements.

India offers a powerful example of what's possible. Power Grid Corporation of India raises about $800 million yearly with an average loan term of nearly 11 years, funding expansion that keeps pace with national plans. Vietnam's separated transmission company invested a record $660 million in 2023, even while its parent utility suffered billion-dollar losses.

The reform would also unlock new revenue streams. A transparent transmission business could support shared network use for renewable developers, corporate clean energy buyers, and cross-border projects like the proposed $30 billion renewable electricity export to Singapore.

Indonesia doesn't need to break up its utility or privatize anything to make this work—it just needs to finish a transformation that's already underway.
