The 'social alpha energy challenge' aims to discover technology innovations with solutions to India's energy challenges or make existing energy networks cleaner and more affordable, Tata Trusts said in a statement.
The entries are invited from innovators across various stages of the energy lifecycle -- generation, transmission and distribution, storage, and consumption -- in multiple sectors such as households, farm, industry, and utility, among others.
The winners will be assessed on parameters such as innovation, business viability, environmental sustainability, social impact, and scalability potential, the statement said.
