Roles of retailers in the peer-to-peer electricity market: A single retailer perspective.

Despite extensive research in the past five years and several successfully completed and on-going pilot projects, regulators are still reluctant to implement peer-to-peer trading at a large scale in today's electricity market. The reason could partly be attributed to the perceived disadvantage of current market participants such as retailers due to their exclusion from market participation-a fundamental property of decentralized peer-to-peer trading. As a consequence, recently, there has been growing pressure from energy service providers in favor of retailers' participation in peer-to-peer trading.
