| Summary/Abstract |
India has set 2070 as the target year to achieve carbon neutrality, while carbon-intensive fossil fuels are still dominating its energy system. In the next five decades, economically optimized energy transition towards renewables is crucial for India to reduce CO2 emissions in an affordable manner. India has installed a large fleet of solar PV, and thus, maximizing their capacity factors plays an influential role in energy transition. This study examines how the state of Karnataka managed to enhance solar PV capacity factor by two-thirds with substantially reduced curtailment from 2017 to 2019. We built, calibrated, and validated a Mixed-Integer Linear Programming (MILP) model with detailed hourly data to quantify the impacts of two major policy changes, being shifting electricity consumption of irrigation from night-time to daytime (load shift) and dispatching electricity generation units by their merit order (economic dispatch). Our results indicate that these two measures could explain about 20% and 70% of the capacity factor increase, respectively, which is equivalent to reducing the cost of solar electricity by about 40%. India and other countries may further expand these policies for accelerating and optimizing energy transition.

| Summary/Abstract |
In the last decade, the EU has driven forward the development and connection of renewable power sources across Europe. This has changed the way in which distribution networks operate, moving from a passive system, to a more active system where generation and demand are located closer together with system states being more complex and variable. Increased penetration of renewable generation into distribution networks is presenting a number of challenges to Distribution Network Operators (DNOs) including the provision of network access in capacity constrained networks. The introduction of Active Network Management (ANM) is enabling an increase in renewable generation connections through enhanced network access in otherwise 'full' networks.
This paper presents a way in which DNOs might move towards Business as Usual (BAU) arrangements for ANM schemes. It is necessary to determine the curtailment arrangements, or Principles of Access (PoA), and from this estimate generation access under ANM and the flow of services and money for different scenarios. In this paper, a comprehensive literature review, detailed case study evaluation on early ANM schemes, quantitative curtailment assessment for different PoA and a qualitative analysis of business models for different ANM PoA is presented in turn with conclusions drawn from these three approaches.

| Summary/Abstract |
Leading the world in manufacturing and installations, China's solar PV sector has attracted the attention of academia, government, and business. However, inadequate attention has been paid to the role of local governments in the development of China's domestic solar industry. This paper describes the omnipresent role of local governments in each stage of solar market development, examines the political motivations for this outsized presence, identifies the consequences of excessive local government involvement, and provides policy recommendations to compliment changes being made at the national and local levels. The paper finds that while local government support has enabled China to become the global leader in solar development, it has also led to overproduction and overcapacity. These outcomes are oftentimes the direct result of local governments acting in accordance with their incentive structures. The findings indicate that the future healthy development of China's solar PV market will be dependent upon enforcement of central policy and aligning the policy objectives and incentives between the central and local levels.
