Proposed Station Would Connect Separate Grids, Enabling Electricity Generated in Remote Sites to Reach a Wider Market
Rebecca Smith Wall Street Journal October 13, 2009
A new proposal to build a transmission link to connect the nation's three major electricity grids -- Eastern, Western and Texas -- is generating interest among energy policy makers because of its potential to accelerate development of renewable energy.
The project, called the Tres Amigas "superstation," to be built at Clovis, N.M., would bring a major change to the U.S. electricity infrastructure by improving connectivity. For example, power produced in Phoenix at this point can't be shipped to Dallas.
The lack of interconnectivity is becoming a larger problem as the nation adds more solar and wind energy to its supply. Much of that power is produced in remote areas and needs to travel to distant population centers, which is problematic under the current setup. Greater connectivity among the grids could open up the market for some renewable-energy developments because the electricity could be sold across a wider region or moved to where it is most needed.
