Singapore closes 200-year gap between electricity and telecoms with innovation

In Singapore on April 29, 2025, the innovative Signal Embedded Power Line (SEPL) technology was presented to the Energy Market Authority and national leaders, marking a significant breakthrough in the intersection of energy and telecommunications. This revolutionary system allows for the simultaneous transmission of power and communication signals through the same infrastructure, effectively addressing issues that have historically segregated these two sectors since the 19th century. The development of SEPL was spearheaded by inventor Kannappan Chettiar, who designed this patented technology using Para-Series Field Embedding techniques. This system enables the delivery of power and real-time data to coexist without the need for modern digital infrastructure including software, cloud systems, or IoT devices. One of the vital features of SEPL is its ability to embed control signals deep within power lines, allowing for seamless communication while curbing electrical noise interference that plagued earlier technologies. The advantages of this technology extend beyond mere integration of services. With SEPL, cities can implement energy-efficient systems such as smart streetlights that respond to ambient conditions and dynamically adjust based on specific needs—providing warnings during emergencies or enhancing pedestrian guidance without necessitating extensive infrastructure changes. The estimated deployment cost for SEPL is S$84 million, advantageous considering the payback period of just three months. This shift away from complex internet-based systems promises a more efficient and reliable way for energy management in urban environments. Given the backdrop of rapid technological advancement, Chettiar's innovative work is a testament to Singapore's dedication to exploring new ideas that can significantly impact the future. The reaction from the People's Action Party (PAP) leadership underscores a willingness to adopt novel concepts that enhance energy efficiency and communication, paving the way for a smarter, more integrated city. This announcement represents hope for an era of advanced infrastructure with the potential for widespread applications across various sectors, positioning Singapore as a leader in energy technology for the 21st century.
