In 2015 the Government of India launched the Street Lighting National Program (SLNP) to reduce energy consumption and GHG emissions from the street lighting sector as part of its National Mission for Enhanced Energy Efficiency (NMEEE). NMEEE is one of the eight national missions under the National Action Plan on Climate Change (NAPCC) which aims to mitigate climate change through energy efficiency measures. Energy Efficiency Services Limited (EESL), a public sector energy service company (ESCO), is the lead agency working in coordination with the Bureau of Energy Efficiency (BEE) for SLNP implementation in India. As of end-January 2019, the states of Andhra Pradesh and Gujarat are leading in SLNP implementation; Rajkot is the first city in Gujarat to carry out street lighting retrofits through SLNP. This case study discusses how Rajkot overcame initial implementation challenges through a pilot project which retrofitted LED street lighting. This was later scaled-up to a city-wide program utilizing ESCO based financial and implementation models. The case study also highlights the co-benefits that the city continues to enjoy through this large scale intervention while leading the path of low emission, green-growth development.
