We Are Pilar Energi
We aim to optimize Indonesian energy consumption by improving existing industrial processes, maintaining asset efficiency and supporting efforts for the energy transition.

Who We Are
Pilar Energi offers a comprehensive suite of solutions aimed at optimizing energy consumption across Indonesia. We leverage advanced energy technologies to assist industries in their transition to net-zero emissions. Our offerings also include corrosion and insulation solutions that minimize energy losses, along with industrial technologies designed to recycle heat and energy from industrial processes.
As a wholly owned subsidiary of Wilson Walton Indonesia (WWI), Pilar builds on WWI's 30-year expertise in corrosion control by expanding into energy solutions, supporting sustainability through both asset and energy preservation.
Process & Pipeline Services
Unfettered defects and inefficiencies are the leading cause of energy loss in industry. Leveraging our 30 years of experience in pipeline services, we provide a broad range of solution in insulation and solutions to solve corrosion under insulation from prevention to inspection.
CUI Resistant Insulation
We provide advanced insulations that delivers superior thermal performance while offering excellent protection against corrosion under insulation.
Cold Tape Wrapping
Protect your pipes from corrosion with industry leading polyethylene wrapping.
CUI Detection System
Identify potentially harmful corrosion under insulation without removing the insulation, reducing time and effort, and enabling predictive maintenance prior to turnaround.
Corrosion Control Engineering & Inspection
Since 1994, corrosion control has been a core activity of our group. We provide comprehensive corrosion control design and engineering services, including SACP, ICCP, CIPS, DCVG, MFL, and other advanced inspection techniques.
Energy Transition
How do we meet the world’s growing demand for energy, and the world’s demands from energy – to be cleaner, safer, more efficient? We believe the answer lies in technology.
Our offerings to support energy transition are integrated small-scale solar panel systems, and technology for sustainable aviation fuels.
Sustainable Aviation Fuels
We provide consulting services for development of medium scale SAF plants ~100,000 ton/ year capacity and also securing feedstock and offtakers
Solar Energy Solution
Small to medium scale solar systems that are easily deployed, ideal for individuals or communities.
Industrial Technology
Many industrial plants were constructed 20 to 30 years ago, and it's natural that inefficiencies have emerged. For instance, wasted heat that could be recycled or energy-intensive systems like cooling water networks, when not operating at their design rating, often lose efficiency. This inefficiency results in higher energy consumption and increased operational costs.
We offer solutions to enhance these outdated technologies, which are often overlooked. Our innovative revenue-sharing models allow plants to improve without requiring significant capital investment. This not only boosts efficiency but also reduces emissions.
Water Recycling System Optimisation
Water recycling systems in plants requiring significant cooling energy can be highly energy-intensive. Even a small improvement in efficiency can lead to substantial cost savings for the plant and a significant reduction in emissions.
Waste Heat Recovery
Utilize waste heat from industrial processes to save energy. By harnessing this excess heat, it is possible to significantly reduce the need for additional energy inputs, thereby lowering overall costs.
