Peer-to-Peer Energy Resource Sharing in Rural Communities: Enabling Technologies, Applications, and Challenges

Standalone energy supply system has been in the limelight, especially in rural areas since it can provide cheap electrical supply to the local communities. Energy supply is always a problematic condition in many developing countries that significantly affects progress and inclusive economic development. Furthermore, excess energy generated is wasted due to insufficient battery storage. To confront these recurring problems, peer-to-peer energy resource sharing has emerged as a promising solution, offering a decentralized system and approach to reduce reliance on the grid energy resource. The system enables prosumers to share excess energy with consumers, reducing dependence on grid and lowering the cost of electricity. However, peer-to-peer energy resource sharing is still a relatively new technology in developing countries, especially in rural communities, needing enabling technologies, support, and sustainable policies and financing models. To this end, this study aims to provide comprehensive understanding of the state of the art of peer-to-peer energy resource sharing in rural communities.
