Abstract

This study assesses the economic and technical performance of four energy policy scenarios for Jordan's residential photovoltaic (PV) systems: net metering, net billing, zero-export with battery storage, and sell-all-buy-all. With the recent introduction of time-of-use (TOU) tariffs and policies addressing the “duck curve” effect, the research focuses on optimizing PV system sizing across different regulatory frameworks. A detailed techno-economic analysis evaluates these scenarios based on energy production, cost savings, payback periods, and energy self-sufficiency. The findings indicate that net metering and net billing offer the highest cost savings and the shortest payback periods (∼3 years). While the zero-export strategy with battery storage enhances energy self-sufficiency by up to 70%, it requires a higher upfront investment. The sell-all-buy-all scenario supports larger system sizes, achieving a low levelized cost of electricity (0.0696 USD/kWh) and a net present value of 619 USD. Additionally, the study identifies a critical feed-in tariff threshold of 0.055 USD/kWh, at which net billing becomes as financially attractive as net metering. These insights offer valuable recommendations for policymakers to optimize net billing rates and TOU tariffs, promoting the expansion of Jordan's renewable energy sector.

约旦住宅光伏系统电价政策的技术经济评估

本研究评估了约旦住宅光伏（PV）系统的四种能源政策方案的经济和技术性能：净计量、净计费、电池存储零出口和全买全卖。随着最近引入的分时电价（TOU）和解决“鸭子曲线”效应的政策，研究重点是在不同的监管框架下优化光伏系统规模。详细的技术经济分析基于能源生产、成本节约、投资回收期和能源自给自足来评估这些方案。研究结果表明，净计量和净计费提供了最高的成本节约和最短的投资回收期（~ 3年）。虽然采用电池储能的零出口战略可将能源自给自足率提高70%，但它需要更高的前期投资。“全卖全买”方案支持更大的系统规模，实现低水平电力成本（0.0696美元/千瓦时）和净现值619美元。此外，该研究确定了0.055美元/千瓦时的关键上网电价门槛，在这一门槛下，净计费与净计量在经济上具有同样的吸引力。这些见解为政策制定者提供了有价值的建议，以优化净计费费率和分时电价，促进约旦可再生能源部门的扩张。

期刊介绍： Utilities Policy is deliberately international, interdisciplinary, and intersectoral. Articles address utility trends and issues in both developed and developing economies. Authors and reviewers come from various disciplines, including economics, political science, sociology, law, finance, accounting, management, and engineering. Areas of focus include the utility and network industries providing essential electricity, natural gas, water and wastewater, solid waste, communications, broadband, postal, and public transportation services. Utilities Policy invites submissions that apply various quantitative and qualitative methods. Contributions are welcome from both established and emerging scholars as well as accomplished practitioners. Interdisciplinary, comparative, and applied works are encouraged. Submissions to the journal should have a clear focus on governance, performance, and/or analysis of public utilities with an aim toward informing the policymaking process and providing recommendations as appropriate. Relevant topics and issues include but are not limited to industry structures and ownership, market design and dynamics, economic development, resource planning, system modeling, accounting and finance, infrastructure investment, supply and demand efficiency, strategic management and productivity, network operations and integration, supply chains, adaptation and flexibility, service-quality standards, benchmarking and metrics, benefit-cost analysis, behavior and incentives, pricing and demand response, economic and environmental regulation, regulatory performance and impact, restructuring and deregulation, and policy institutions.
