Are there similar existing projects anywhere that Hawaii can learn from?
Yes. There are more than 20 undersea transmission cables in operation around the world. There are several similar systems in Europe, the Philippines, Japan, and the mainland U.S. Many are longer and deeper than will be necessary in Hawaii. The technology is well established and there are a number of international companies able to do the work. The National Renewable Energy Laboratory (NREL) has been leading a Technical Review Committee with some of the best expertise across the globe in this area, and they are continuing to give us extremely valuable technical advice. In addition, there are at least nine undersea communications cables connecting the Hawaiian Islands.
