Bright Lights for Brighter Future

Eight cities in Indonesia may make substantial savings in electricity bills up to 60% and thus help reducing Greenhouse Gases emissions when replacing conventional street lights with LED

As Indonesia’s economy continued to grow impressively in the past decade, so did the demand for energy and electricity to fuel and maintain such growth. Indonesian energy consumption rate is the highest in South-East Asia and the electricity demand due to rapid urbanization rose by 4.8% annually and is predicted to nearly triple by 2035. Unfortunately, as fossil fuels constitute almost all of Indonesia’s source of energy and electricity, it is inevitable that CO2 emissions, one of major component of greenhouse gases (GHG), will nearly double by 2035.

Clearly, both public and private sectors must implement measures to reduce electricity consumption if Indonesia wants to succeed in achieving its goal of reducing greenhouse gases. This creates an opportunity to substitute outdated technologies with more efficient ones. LEDs (light-emitting diodes) is one such efficient technology that can replace energy-hungry conventional street lights used in all Indonesian cities.  

With support of GIZ PAKLIM project, eight city governments in Java (Semarang, Pekalongan, Surakarta, Yogyakarta, Malang, Probolinggo, Pasuruan, Mojokerto) together with OSRAM, lamps producing company, initiated a program in 2012 that aimed to replace all current street lights with LED lights. “The first thing we did, “ says Mohammad Nurhadi, Component Manager for PAKLIM’s Climate Change in Cities and Urban Area programme, “was trainings for city government staff in charge of street lightings to collect data of electricity use for all types of street lights in their cities. After that we were able to conduct simulation on how much savings can be made by replacing all conventional street lights with LEDs. “ 

These cities are pioneers in introducing climate-friendly city infrastructure. What is more, the use of LED brings many additional benefits. Safety improvements through better lighting, reduced dazzling effect and creation of jobs in the operation of public infrastructure are some. Analysis of energy efficiency in the eight cities has revealed significant potential savings. It was showcased by retrofitting street lighting on a model street in Malang, East Java, with LED lamps that yielded energy savings of about 60 percent and triggered positive effects on citizens’ daily life in the neighborhood.

The success in the energy saving simulation and LED street-lighting retrofitting in Malang has led expansion of the Smart Street Lights program in 2014 to 22 cities, starting with Makassar and Surakarta. The program is led by the Ministry for Energy and Mineral Resources.

This public initiative in cooperation with OSRAM is a vivid example of a Development Partnership between Public and Private Sectors. PAKLIM’s advisory work on financing new technologies that goes along with this partnership assists City Governments in overcoming financial barriers and clears the way for adoption of further climate friendly infrastructure. It also shows that fossil fuel consumption and the resulting GHG emissions can be drastically reduced through energy efficient public infrastructure.
