At NREL’s Flatirons Campus substation is part of the Power Generation Upgrade Project changing the source of utility power at the Flatirons Campus from the distribution network that feeds businesses and houses to the transmission network that ties all the power plants and substations together.
In that process, the campus’ transmission limitation increased from 10 megawatts (MW) to 19.9 MW, enabling twice as much power transmission as before, allowing researchers to test multiple types of technologies on the same electrical grid with enough power to run them effectively and add more testing scenarios with greater electrical stability.
