埃斯塔卡德巴雷斯角（伊比利亚的最北端）附近地区由于其突出的位置，具有巨大的波浪能开发潜力，平均深水波功率值超过40 kW/m。最新的SIMAR-44数据集由44年（1958-2001年）的后报数据组成，与波浪浮标数据和数值模拟一起使用，以详细评估这一巨大的能源资源。大部分的能量来自IV象限的波浪，由盛行的西风带吹过大西洋的长水道产生。结合散射图和能量图，用于计算平均年中所涉及的海况的波浪能。狮子的份额被示出对应于2和5米之间的显着波高和11和14秒之间的能量周期。近岸能量模式，然后检查使用沿海波浪模型（SWAN）参考四种情况：平均波能量，增长波能量（在风暴的方法），极端波能量（在风暴的高峰期）和衰减波能量（风暴消退）。不规则的测深发现产生本地集中的波能在近岸前角和奥尔特加尔角之间，并在前面的埃斯塔卡德巴雷斯角，具有类似的模式（但不同的波功率）在四种情况下。这些增强的波浪能的近岸区域作为波浪能操作的预期地点是最感兴趣的。其中最大的一个直接位于奥尔特加角以西的一个大型水下山脉的背风处。总之，Estaca de Bares地区是欧洲最有希望开发波浪能的地区之一。
The area around Cape Estaca de Bares (the northernmost point of Iberia) presents a great potential for wave energy exploitation owing to its prominent position, with average deepwater wave power values exceeding 40kW/m. The newly available SIMAR-44 dataset, composed of hindcast data spanning 44 years (1958–2001), is used alongside wave buoy data and numerical modelling to assess this substantial energy resource in detail. Most of the energy is provided by waves from the IV quadrant, generated by the prevailing westerlies blowing over the long Atlantic fetch. Combined scatter and energy diagrams are used to characterise the wave energy available in an average year in terms of the sea states involved. The lion's share is shown to correspond to significant wave heights between 2 and 5m and energy periods between 11 and 14s. The nearshore energy patterns are then examined using a coastal wave model (SWAN) with reference to four situations: average wave energy, growing wave energy (at the approach of a storm), extreme wave energy (at the peak of the storm) and decaying wave energy (as the storm recedes). The irregular bathymetry is found to produce local concentrations of wave energy in the nearshore between Cape Prior and Cape Ortegal and in front of Cape Estaca de Bares, with similar patterns (but varying wave power) in the four cases. These nearshore areas of enhanced wave energy are of the highest interest as prospective sites for a wave energy operation. The largest of them is directly in the lee of a large underwater mount west of Cape Ortegal. In sum, the Estaca de Bares area emerges as one of the most promising for wave energy exploitation in Europe.
