Nasirov, S., Gonzalez, P., Opazo, J., & Silva, C. (2023). Development of Rooftop Solar under Netbilling in Chile: Analysis of Main Barriers from Project Developers' Perspectives. Sustainability, 15(3), 2233.
Abstract: The development of rooftop solar PV generation has significant potential to generate enormous benefits to the electricity systems in achieving emission reduction targets and meeting increasing global energy demand, but could also make the power systems more resilient and affordable. In 2012, the Chilean government introduced a net billing law (Law 20.517) to incentivize consumers to sell their excess renewable electricity into the grid, which was expected to lead to a significant growth in rooftop solar. However, to date, the advancement of these technologies in the country has been very limited due to various barriers. For this reason, identifying and mitigating the main barriers that impede the advancement of development of rooftop solar is necessary to allow the successful deployment of these technologies. Based on data collected from a questionnaire survey and interviews conducted among the project developers in rooftop solar, the authors identify and rank the major barriers to the adoption of these technologies in Chile. Our findings show that the most significant barriers include “high investment and recovery period for the customer”, “lack of incentives to develop projects in the sector”, “rigid regulations regarding project size”, and “long administrative process and grid connection costs”. Furthermore, we discuss the most critical barriers in detail together with policy recommendations to overcome them.

Abstract: In the last decade, the importance of exploiting Chile's Renewable Energy Sources (RESs) has increased significantly, as fossil fuel prices have risen and concerns regarding climate change issues grown, posing an important threat to its economy. However, to date, the advancement of Renewable Energy Technologies (RETs) in the country has been very limited due to various barriers. For this reason, identifying and mitigating the main barriers that hamper the advancement of RETs is necessary to allow the successful deployment of these technologies. Based on data collected from a questionnaire survey and interviews conducted among the major renewable project developers, the authors identify and rank the major barriers to the adoption of renewable energy technologies in Chile. Our findings show that the most significant barriers include grid connection constraints and lack of grid capacity, longer processing times for a large number of permits, land and/or water lease securement and limited access to financing. Furthermore, we discuss the most critical barriers in detail together with policy recommendations to overcome them.

Abstract: Chile has become increasingly dependent on energy imports and its energy demand has grown exponentially in the past decade, impacting the environment and the production costs in the economy. In fact, electricity prices have doubled and it is expected that they will soar in the next decade if Chile does not find a solution for its dependence on imported energy resources. Recent developments, particularly improvements in the regulatory framework and incentives for renewables, have accelerated the growth process and investment opportunities of renewable energy technologies (RETs). However, RETs have faced a number of constraints affecting their penetration. In this article, we review the existing opportunities and also identify and rank the major barrier categories for the development of RETs in the Chilean context. For this purpose, the analytical hierarchy process technique has been utilized for ranking the barriers based on experts' opinions (selected from academia and industry).
