This study focuses on assessing the offshore wind energy potential along the Indian Coast over a 10-year period (2005–2014) using high-resolution data from the simulation of the Weather Research and Forecasting (WRF) model. The predicted wind fields are utilized to identify potential sites, estimate offshore wind technical potential at different depths (ranging from 30 to 200 meters), and develop wind energy blocks within the Indian Exclusive Economic Zone. To ensure environmental protection, environmentally sensitive areas have been excluded from the offshore wind potential sites. The gross technical offshore wind potential was estimated to be 3941 GW within depths of 30–200 meters, excluding environmentally sensitive areas within the 0 to 30-m depth range. High-potential sites have been identified in the coastal states of Gujarat, Maharashtra, Kerala, and Tamil Nadu. The environmental offshore wind potential across these identified sites (feasible OWE sites) along the Indian coast is estimated at 432.34 GW within the 30 to 200-m depth range (at 140 m AGL).

According to the report by the Central Electricity Authority (CEA), the predicted offshore wind power has the potential to significantly contribute to the country's total electrical power requirement for 2020–21. This study encourages exploration of offshore wind energy possibilities along the Indian coast and highlights the management challenges at suitable sites, including addressing potential conflicts between offshore wind energy development and other marine uses. The findings of this study can assist in the assessment of offshore wind resources and provide decision-makers with scientific evidence for the development of offshore wind energy in India, while also considering the management and conservation of marine ecosystems.

考虑到生态保护,印度海岸的海上风能潜力

本研究的重点是利用天气研究和预报 (WRF) 模型模拟的高分辨率数据来评估印度海岸 10 年期间(2005 年至 2014 年)的海上风能潜力。预测的风场用于识别潜在地点,估计不同深度(30至200米)的海上风电技术潜力,并在印度专属经济区内开发风能区块。为了确保环境保护,环境敏感地区已被排除在海上风电潜力地点之外。30-200米深度内的海上风电总技术潜力估计为3941吉瓦,不包括0-30米深度范围内的环境敏感区域。古吉拉特邦、马哈拉施特拉邦、喀拉拉邦和泰米尔纳德邦等沿海邦已确定了高潜力地点。印度海岸沿线这些已确定地点(可行的 OWE 地点)的环境海上风电潜力在 30 至 200 米深度范围内(AGL 140 m)估计为 432.34 GW。

根据中央电力局 (CEA) 的报告,预计海上风电有可能为该国 2020-21 年的总电力需求做出重大贡献。这项研究鼓励探索印度海岸海上风能的可能性,并强调适当地点的管理挑战,包括解决海上风能开发与其他海洋利用之间的潜在冲突。这项研究的结果可以协助评估海上风资源,为决策者提供印度海上风能发展的科学依据,同时也考虑到海洋生态系统的管理和保护。
