According to a recent report, South Carolina-based Alternative Transmission Inc. is preparing to propose an up to $6 billion underwater transmission line between the U.S. east coast and the island state of Puerto Rico, which has suffered major energy issues over the last five years. 

The report says the transmission line could bring more than 2 GW of mainland U.S.-generated electricity to Puerto Rico. This could be a significant step forward for Puerto Rico, whose power grid issues were brought to global headlines in 2017 after Hurricane Maria knocked out power to the island. It was 11 months before power was restored to the entire island. Natural disasters in the years since have also knocked out power for extended periods. 

The company, Alternative Transmission Inc., has allegedly asked the FERC to confirm that the transmission line would not put Puerto Rico's power grid under the federal agency's jurisdiction. The FERC's decision is pending, and it will be interesting to see whether the FERC claims that the power line means Puerto Rico's energy system would be thrust under the purview of the U.S. government. If the FERC says Puerto Rico's grid remains independent, that could mean a lot of Texas's ability to connect transmission lines to out-of-state power generators. Texas's power independence became a major talking point following the winter storm that nearly took out the state's grid.

Being a Researcher for more than 20 years to generate clean energy, I have learned enough and enough.  We have many simple methods to generate Millions of MW of clean energy by using natural resources, but the fact is that scientists and researchers do to reach this level. But they are thinking of solutions with well complicated. I can say this very boldly because my research activities proved to me beyond doubt that many other simple ways for alternative sources of energy generation to make power"available" abundant always.  Therefore, I express, underway transmission may be costlier and a tough task. I am writing this based on my better experiments and research activities, and am now in the process of making a machine to prove it is better.

My slogan is to stop lengthy cable power transmissions. As per my inventions of new methods of clean energy, each house can have its own power generating units. For information, as per my inventions, future energy scope is that, in the existing Hydro Power Plant,10 times more additional power can be generated using the same reservoir and water without disturbing the normal function.  For that, Using sea  water, in a single spot, a minimum of 10,000 MWs can be arranged at the seashore or using surrounding wasteland.

$6 billion would build how much distributed solar and storage? Transmission is inherently inefficient, and presents security problem, susceptible to domestic terrorism and outages. Generation needs to be near load, and distributed location for reliability.

Totally agree Carol - while I appreciate the attempt of creative solutions, a long-range line that also goes through international waters is too risky and inefficient for such an investment.
