Data at the Energy and Mineral Resources Ministry showed that in the past eight years, ratio electrification has risen from 67.2 percent to 98.05 percent with electricity still generated mainly with fossil energy.
The energy mix is till dominated by fossil energy with coal accounting for 58.64 percent, gas for 22.48 percent, oil 6.18 percent, and renewable energy for around 12.71 percent.
In order to increase the electrification ratio with renewable energy to make up 23 percent of the energy mix in 2025, the government would need support and cooperation from advanced nations, Director General of New and Renewable Energy Rida Mulyana said.
"We are aware that in order to achieve the target, support and cooperation from nations already advanced in the utilization of renewable energy are needed," Rida said.
The support could be in the form of fund, technology, expansion of capacity and inputs to develop renewable energy in Indonesia, he said.
He said Germany is one of important partners of the Indonesia government in development of renewable energy, adding Indonesia and Germany have cooperated for 25 years in the development of renewable energy.
He said he hoped the cooperation program with Germany would help Indonesia sort out any problem in the development of renewable energy.
"I hope the cooperation program between Indonesia and Germany could help us overcome the challenges in the process of development to achieve the energy mix target in 2025 with renewable energy contributing 23 percent to the country`s energy consumption," he said.
Meanwhile, the Energy and Mineral Resources Ministry said electrification ratio in the country`s most backward region of Papua has reached 72.04 percent.
