While interconnection rules are designed to ensure the technical integrity and financial sustainability of power systems, stringent policies and punitive pricing signals have inadvertently led to the proliferation of unauthorised DERs in many parts of the world. Unauthorised DERs pose a range of technical, financial and safety risks to the power system, yet the drivers of non-compliance remains undocumented in the literature. This paper explores the drivers of non-compliance in South Africa, where by 2024 >50 % of behind-the-meter solar capacity is illegally connected to the grid. By quantifying the misalignment of private and public DER value streams, this study identifies key barriers to compliance, including high interconnection costs, lengthy approval processes, and misaligned pricing signals. A comparative case study between three South African municipalities illustrates how different utility governance approaches impact the business case for DER investment. A simple but important finding is that utility approaches can significantly impact a customer's decision to follow the formal interconnection process. A revenue impact modelling exercise revealed the detrimental impacts of unauthorised DERs on utility revenue. These results suggest that, in jurisdictions facing unauthorised DERs, early financial incentives are essential to minimise non-compliant installations and the associated utility revenue erosion. As DER penetration expands into new global regions, these findings are expected to assist utilities and regulators in developing appropriate regulatory frameworks that facilitate the sustainable integration of DERs.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"85 ","pages":"Article 101661"},"PeriodicalIF":4.4,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143237090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using data collected from on-site surveys, this study aims to estimate electricity consumption in rural Mozambique at the edge of the electricity grid and examine the factors that influence it. The consumption is estimated for households, community institutions, and productive users in four different localities. Three of the localities are off-grid and rely largely on Solar Home Systems, while one is a small town and has access to grid electricity. To analyze the determinants of electricity consumption, multiple linear regression models are used. The results show that households account for >62 % of the total electricity consumption. The average household consumption in the grid-electrified town (2.54 kWh/day) is significantly higher than in the off-grid localities (0.04 to 0.24 kWh/day). Furthermore, the load profiles of households in the grid-electrified town and off-grid localities differ significantly. However, productive users consume the most electricity per user in all localities. The regression analysis shows a positive and strong relationship between consumption and appliance ownership, with refrigerators and televisions having the most significant influence in the grid-powered locality, and cellphones and LED lamps having the biggest effect in the off-grid areas. The study demonstrates the substantial spatial and sectoral differences in electricity consumption in rural Mozambique. It also reveals how access to grid electricity, productive use, and appliance ownership shape electricity consumption in rural Mozambique. Understanding these dynamics is thus crucial for accurate demand forecasting and optimal rural electrification planning.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"85 ","pages":"Article 101662"},"PeriodicalIF":4.4,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143237089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Second, the most impactful pathways through which regulatory regimes affect solar power deployment include governance, competition among differently-sized developers, procurement, labor, and evenness within the same national jurisdiction.

The installation of SWHs is also positively correlated with the households' main income and their heads' educational attainment and age. We also control for dwelling characteristics and find that households in urban areas and those living in a house, owning the dwelling, and having a bathroom are more likely to adopt SWHs.

Applying this method, we evaluate China's ICPs of renewable policies from 2009 to 2021.

This price level is on par with explicit carbon price in the early stage of China's national emissions trading system, highlighting the country's substantial efforts to address climate change by deploying renewables. Scrutiny of different provinces and renewable generation technologies uncovers great variations in ICPs, which implies significant heterogeneity in abatement costs and policy efficiency within the renewable energy sector.
