Abstract
Conventional fossil-fuel energy resources are being drastically depleted; thus, the current shift towards renewable energy (RE) resources has become imperative. However, there are many impediments to the adoption of renewable power generation. These impediments can be overcome by enacting policies to encourage the acceptance of sustainable energy resources. For instance, the net-metering policy can provide the necessary incentives to promote the development of local distributed energy sources, primarily solar photovoltaic and wind generators. While there has been significant advancement and development in net-metering in Asia with the increased penetration of RE, at present there is a lack of systematic review in this area. This paper aims to present an in-depth review on net-metering advances and challenges, current RE shares, and future RE targets in the Asian region. Additionally, a case study is performed and an economic analysis of net-metering regulations in an Asian country is carried out. In this study, the monetary benefits of net-metering policies for residential consumers are proved. It is envisaged that the information gathered in this paper will be a valuable one-stop source of information for Asian researchers working on this topic.
Highlights
Energy production and consumption play a vital role in the development of nations
The obtained results conclude that the economic benefits of the net-metering scheme are beyond any doubt; the results indicate that the payback period decreases initially with the maximum generating capacity of solar panels up to 4 kW and increases after that
This study reveals that majority of the residential and commercial consumers of ‘‘Agusan del Norte Electric Cooperative, Inc. (ANECO)’’ are well-aware of the benefits of the solar PV systems, but a vast majority of consumers are unaware of the net-metering incentives
Summary
Energy production and consumption play a vital role in the development of nations. The amount of consumed energy per capita is one of the indicators of the developmental pace of a nation. Consumers can meet their energy demands by taking energy from the grid, and at the same time they can be energy producers by injecting excessive energy into the grid and receiving economic benefits in return This mechanism requires net-metering as part of the supporting infrastructure [24]. A detailed review of the advancements in net-metering mechanism and the research work available on the net-metering policy frameworks for Asian countries is presented in Section IV; the current RE penetrations and future targets are given in detail . NET-METERING – INTERNATIONAL EXPERIENCE The net-metering concept is being used widely in various countries to exploit green energy resources with the view of overcoming global warming challenges and ensuring a sustainable and clean energy provision to consumers.
