About The Project

The EPRI SUNBURST Project is a collaborative project for monitoring of geomagnetically-induced currents (GIC's) and their impact on the power grid.

Utility membership funds the operation of the network of monitors, currently consisting of about 50 monitors on transformer neutrals at utility substations throughout North America.

The monitoring network collects GIC data during geomagnetic disturbances, providing a global and local view of the GIC in near real-time.

The collected GIC data helps electric utilities to better understand GIC flows on their transmission system, validate GIC models used to simulate extreme GMD events, and assess vulnerability.

The EPRI Sunburst Project has moved to a new domain: sunburstproject.net

For most users, passwords from the old system will no longer work. Everyone who had a userid on the old system will receive an email with login credentials for the new system. These emails will be sent by February 9, 2018.
