Resumen
New requirements for a better sustainable energy policy around the world is easy to observe, many projects in
sustainable energy are developed wherein the academia works together the authorities and commercial firms such as
electrical grid utilities. In distribution transformers one of the suggested solutions is to replace mineral oils used as
dielectric and coolant for natural ester fluids, they provide improved technical properties making them a safe substitute of
mineral oil. Natural esters are based on clean technology in order to guarantee requirements from utilities. The main goal
of the present paper is to present a technical-economic analysis obtained from five years of applications of oil-immersed
transformers using natural ester fluids in Colombia. The methodology considers forty-four oil-immersed distribution
Transformers, a half use mineral oil and the other side use natural ester, operating under the same load regime. Results
evidenced the feasibility of implementing this technology because the costs are very similar and the reduction of risks
and environmental impact is considerable.
