STUDY ON BUSINESS SCHEME OF A COMMUNITY-LEVEL DECENTRALIZED AND SELF-RELIANT ENERGY NETWORK

Allocation of co-benefits among stakeholders and feasibility evaluation by use of social-economic internal rate of return

Abstract

Community-level decentralized and self-reliant energy network is expected to contribute to create a sustainable community as well as its self-vitalization and energy resiliency. But implementation of this system requires consensus among variety of stakeholders and long payback period, which are major hurdles. This study proposes the following concept and methods; (1) PPP business scheme consisting of two types of actors; "community-level energy network infrastructure operating company" and "on-site energy production and service providers" (2) Proper re-allocation of cost and co-benefits among stakeholders by taking advantage of opportunities of adjusting tariffs, taxes, subsidies for the purpose of equalizing each stakeholder's B/C.
