In the remote and isolated island Manpura in southern Bangladesh, located within the Bhola district and surrounded by the Meghna River, most communities rely on farming and fishing for their livelihoods. Due to its isolation, the island is not connected to the mainland's electrical grid. In this study, a freestanding green hybrid energy system was proposed for the Manpura island using HOMER software to meet the electricity needs of its 17,016 households. The average load for the system is 9,149.87 kWh per day, with an annual peak load of 2,112.6 kW. The system would utilize PV panels, hydrokinetic energy, biogas, wind turbines, storage, and a converter, with a total Net Present Cost (NPC) of 23,796,260.00 and a Cost of Energy (COE) of $0.5515. This hybrid energy systems would provide a sustainable and cost-effective long-term power solution for the island while preserving its natural beauty.

“…"Replanting" (discussed in [8]) and "end-of-life extensions" (Table 3) did not find resonance in the offshore wind literature. There were 280 publications on wind and repowering on Scopus with the potential to transfer expertise from onshore to offshore wind, as the repowering of onshore wind farms is already more widespread (see, e.g., [207][208][209][210][211][212][213][214][215][216]).…”

Circular economy and renewable energy infrastructure such as offshore wind farms are often assumed to be developed in synergy as part of sustainable transitions. Offshore wind is among the preferred technologies for low-carbon energy. Deployment is forecast to accelerate over ten times faster than onshore wind between 2021 and 2025, while the first generation of offshore wind turbines is about to be decommissioned. However, the growing scale of offshore wind brings new sustainability challenges. Many of the challenges are circular economy-related, such as increasing resource exploitation and competition and underdeveloped end-of-use solutions for decommissioned components and materials. However, circular economy is not yet commonly and systematically applied to offshore wind. Circular economy is a whole system approach aiming to make better use of products, components and materials throughout their consecutive lifecycles. The purpose of this study is to enable the integration of a sustainable circular economy into the design, development, operation and end-of-use management of offshore wind infrastructure. This will require a holistic overview of potential circular economy strategies that apply to offshore wind, because focus on no, or a subset of, circular solutions would open the sector to the risk of unintended consequences, such as replacing carbon impacts with water pollution, and short-term private cost savings with long-term bills for taxpayers. This study starts with a systematic review of circular economy and wind literature as a basis for the coproduction of a framework to embed a sustainable circular economy throughout the lifecycle of offshore wind energy infrastructure, resulting in eighteen strategies: design for circular economy, data and information, recertification, dematerialisation, waste prevention, modularisation, maintenance and repair, reuse and repurpose, refurbish and remanufacturing, lifetime extension, repowering, decommissioning, site recovery, disassembly, recycling, energy recovery, landfill and re-mining. An initial baseline review for each strategy is included. The application and transferability of the framework to other energy sectors, such as oil and gas and onshore wind, are discussed. This article concludes with an agenda for research and innovation and actions to take by industry and government.

“…Previous analyses of wind repowering potential in India rely on simplified methods of capacity summation by vintage year and lack an assessment of resulting changes in energy yield [15,21]. Detailed analyses of changes in energy yield are limited to case studies of individual wind farms [22][23][24][25]. Other studies have used detailed energy system model representations of the Indian electricity network to assess operational reliability consistent with the expanded use of wind technology [26][27][28], while others have focussed on quantifying technically achievable wind resource potential [29][30][31] and spatio-temporal generation patterns thereof [32][33][34].…”

India’s ambitious net-zero climate goals include plans for a four-fold increase in current levels of wind energy generation by 2030. Many existing wind farms in India occupy sites with the best wind resources nationally but use older, smaller turbines that achieve lower capacity factors compared to modern turbine designs. A strategy of replacing existing wind turbines with state-of-the-art models (termed repowering) could boost capacity factors and ensure maximal use of available wind resources. However, a nationwide assessment of the potential wind generation increases resulting from repowering is currently lacking for India. Here, we present the first validated synthetic wind generation dataset for India based on reanalysis data and show that full repowering of the existing fleet of wind turbines could boost capacity factors by 82% nationwide (from 0.19 to 0.35). Our assessment of attainable capacity factors under full repowering exceeds equivalent estimates within the National Electricity Plan of India and national decarbonisation pathways compiled by the Intergovernmental Panel on Climate Change, suggesting less total installed capacity is required to achieve specific generation outcomes than previously estimated. Ongoing technological progress, leading to increased turbine dimensions, will drive capacity factors beyond the levels estimated here, which could further add to the generation benefits of repowering. Yet, despite the higher average output from a repowered fleet of wind generators, substantial variability in generation across timescales persists, highlighting the increasing need for power system flexibility within a decarbonised energy system.
