May 10 (Reuters) - Grid operator PJM issued a warning on Friday to its generation and transmission companies that a possible geomagnetic disturbance could impact the PJM system.

Although the National Oceanic and Atmospheric Administration classifies level K-8 as "severe," PJM does not anticipate any significant impacts or emergency conditions at this time, the company said.
