With support from the World Bank’s Energy Sector Management Assistance Program (ESMAP) as part of the Sustainable Energy and Emissions Planning (SUEEP) Program, IIEC conducted a feasibility study for a pilot demonstration using LED retrofits in Surabaya to demonstrate the energy savings, emissions reduction and financial benefits that could be realized by the City Government of Surabaya (CGS). The study looked at the viability of energy efficiency (EE) lighting technologies, evaluated implementation approaches, and developed an EE implementation plan with proposed financial arrangements for street and outdoor lighting, consistent with Indonesia’s PPP framework.

Surabaya is the second largest city in Indonesia and it has good coverage of street and outdoor lighting services. The City of Surabaya had about 75,000 luminaires in 2014, and the majority of which are high pressure sodium (HPS). The operating costs of street and outdoor lighting including new installation and maintenance in Surabaya nearly doubled over the past five years.

IIEC supported Surabaya to evaluate the pilot tests of LED technologies, seen as short and long term options for energy efficient street lighting in the city. To date, more than 1,500 LED luminaires have been installed along main traffic routes and major parks in the city. The successful implementation of the pilot phase will allow for the CGS to leapfrog to the large-scale implementation phase. The citywide investment to transform all street and outdoor lighting in Surabaya to LEDs will result in annual electricity and maintenance cost savings of about US$5-$7 million after 2020.
