Abstract
In order to realize the best practices to allow the individuals participate in renewable energy production, a collection of legislation was ratified, and a set of decisions was introduced to encourage the prosumer concept. This notion, which is called Net Metering (NEM), is a billing mechanism that credits PV solar system owners for the energy injected to the grid. Lebanon adopts the NEM policy to reduce the demand and boost the grid through increasing the generation capacity. The decline of solar equipment cost encourages people to subscribe to the NEM service by utilizing the PV solar systems. The implementation of the NEM service provides the customers with leverage over their electricity bills. However, connecting the home micro grid into the vast grid is not easy. It imposes many technical challenges which are discussed in this article.
Highlights
In order to realize the best practices to allow the individuals participate in renewable energy production, a collection of legislation was ratified, and a set of decisions was introduced to encourage the prosumer concept
All that you need in addition to the PV system installation is to replace the old unidirectional electromechanical meter with a new electronic bi-directional meter, which mounted by Electricite du Liban (EDL) after you have subscribed to this service
In order to ensure the installation’s protection and safety from hazards, in addition to proper performance and efficiency, the PV installations should be in compliance with regulations and comply with different standards according to the country/region in which it is used
Summary
A major support for the expansion of solar energy in Lebanon is the Net Metering NEM policy which has been adopted and approved by the Electricite du Liban (EDL) through Decision No 318-32 / 2011. EDL will reset the counter to zero to start all over In this case, any energy surplus is not financially remunerated, but is considered as a contribution to EDL’s electricity production [1]. Any energy surplus is not financially remunerated, but is considered as a contribution to EDL’s electricity production [1] This implies that oversizing of the solar Photo Voltaic (PV) system to more than the average annual energy consumption will increase its initial cost, while the return will remain constant, subsequently raising the system's payback period. 1.1 Subscription Any electricity subscriber can apply for energy NEM by filling out the net metering interconnection application (at the EDL website), and uploading it with all required documentation. The site drawing, single line diagram, and equipment data sheet are attached
