What is Wattershed?
Wattershed will make high temperature superconducting transmission (HTS-HVDC) seaworthy, by combining this fundamental breakthrough in material science with proven innovations from the offshore oil and gas industry. Wattershed’s patent (U.S. Patent No. 8,655,496) takes advantage of the time-phase shift between demand curves across eight or more time zones. Idle capacity at night or stranded intermittent renewables on one grid (or one continent) will find a demand load on another grid. The company will initially connect regional grids along the coastlines, and ultimately connect continents. In North America and Europe, 60%-75% of generation and transmission assets sit idle during off-peak hours, while India and China suffer brownouts from lack of supply, and post-Fukushima Japanese customers pay peak pricing of $.49/kWh. North America wholesale electricity markets offer idle clean supply and stranded renewable supply for $.02/kWh off-peak and $.04-$.06/kWh almost any time. Wattershed could deliver it across the Pacific at a levelized transmission cost of $.03/kWh. Wattershed cable will enable movement of dynamic energy resources seamlessly and efficiently, increasing the supply of clean energy.
