Develop a comprehensive profile of rural electrification in India, mapping growth over the past decade and capturing inter-state variations. Trace the history of and critically examine key policies and legislative reforms focused on electrification. Specifically highlight challenges associated with creating new infrastructure and maintaining reliable supply of electricity, including issues related to pricing, fuel supply etc.  Using secondary evidence and through stakeholder consultations, examine what challenges Uttar Pradesh has faced in implementation of 100% electrification. Undertake a comparative analysis of domestic and/or global best practices from regions with similar socio-economic contexts that have achieved full electrification and managed to provide reliable electricity. Based on your analysis, suggest policy recommendations for improving the quality and reliability of power supply in rural India, more specifically UP.
