在本文中，使用公开的成本数据来计算英国发电的两种海洋能源技术的私人平准化成本：波浪发电和潮汐流发电。这些估算与英国政府确定的其他十种发电技术的成本进行了比较（DTI，2006）。在成本和性能的合理假设下，波浪和潮汐流发电的平准化成本的点估计分别为 90 磅和 81 磅/兆瓦时。敏感性分析显示了这些相对私人平准化成本计算如何受到关键参数变化的影响，特别是假设的资本成本、燃料成本和贴现率。我们还考虑了对可再生能源引入技术差异化金融支持对波浪能和潮汐流发电成本竞争力的影响。此外，我们将当前英国政府支持水平的影响与苏格兰政府提议的更慷慨的海洋技术援助程度进行了比较。 (C) 2010 Elsevier Ltd. 保留所有权利。
In this paper, publicly available cost data are used to calculate the private levelised costs of two marine energy technologies for UK electricity generation: Wave and Tidal Stream power. These estimates are compared to those for ten other electricity generation technologies whose costs were identified by the UK Government (DTI, 2006). Under plausible assumptions for costs and performance, point estimates of the levelised costs of Wave and Tidal Stream generation are 90 pound and 81 pound/MWh, respectively. Sensitivity analysis shows how these relative private levelised costs calculations are affected by variation in key parameters, specifically the assumed capital costs, fuel costs and the discount rate. We also consider the impact of the introduction of technology-differentiated financial support for renewable energy on the cost competitiveness of Wave and Tidal Stream power. Further, we compare the impact of the current UK government support level to the more generous degree of assistance for marine technologies that is proposed by the Scottish government.
