The Duke Energy eGRID (Electrical Grid Research and Innovation and Development) provides wind turbine generator manufacturers a controlled, calibrated environment to test how their machines perform on both 50 Hz and 60 Hz electrical transmission grids. Because true inductance is almost impossible to simulate, researchers are able to replicate realistic fault events on the e-GRID using real air-core conductors.

The eGRID system allows manufacturers to evaluate mechanical and electrical behavior, measure grid compatibility, and simulate disturbances such as fault ride-through conditions without relying solely on field demonstrations.By expanding multi-megawatt testing beyond the wind industry to the broader power conversion market, the eGRID helps manufacturers validate new technologies against increasingly stringent global electrical standards while improving grid reliability, reducing impacts between turbines and the existing grid, and lowering the cost of delivered energy.
