3TIERĀ®, a global leader in renewable energy risk analysis, today announced that it was selected through a competitive solicitation process by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) to update the U.S. wind integration dataset. The integration of high penetrations of wind energy on the U.S. electrical grid poses special challenges given the variable nature of wind generation. The updated foundational dataset is a massive undertaking and will be used directly by NREL to explore the potential impacts of integrating large quantities of wind energy onto the U.S. electrical grid.

"The long-awaited update to the original western and eastern datasets will provide a valuable resource to industry stakeholders for evaluating transmission expansion needs and mechanisms to reliably and cost-effectively manage the grid in high penetration wind scenarios," said Dr. Kirsten Orwig, NREL project leader.
