India’s first-ever Rural LED Street Lighting Project will be implemented by the Government of India (GoI) in Andhra Pradesh (AP). The Energy Efficiency Services Limited (EESL) under the Ministry of Power will retrofit10 lakh conventional street lights with LED lights in Gram Panchayats of 7 districts in AP. This is the first project for rural LED street lighting in the country under the GoI’s Street Lighting National Project (SLNP). In the first phase, the replacement will be undertaken in gram panchayats of the districts of Guntur, Prakasham, Nellore, Kurnool, Kadapa, Ananthapur and Chittoor. This replacement drive in rural areas will help the gram panchayats to cumulatively save approximately 147 million units of electricity annually and lead to reduction of 12 crore tonnes of CO2. The entire upfront capital cost of this project is being funded by French Development Agency Agence Française de Développement (AFD).
