Valuing grid-connected rooftop solar: a framework to assess cost and benefits to Discoms

The study, undertaken in collaboration BSES Rajdhani Power Limited (BRPL) and supported by Shakti Sustainable Energy Foundation, presents a framework to assess the costs and benefits to distribution companies (Discoms) from increasing rooftop solar (RTS) installations. The framework - Valuing Grid-connected Rooftop Solar (VGRS) - included factors such as procurement costs for capacities added under new power purchase agreements, variable costs paid to generators, transmission charges, distribution capacity upgradation costs, working capital requirements, renewable energy certificate costs, transmission and distribution losses, and revenue losses.
