## Abstract

The Commission is revising its regulation to eliminate the requirement to submit FERC-566 (Annual Report of a Utility's 20 Largest Customers) for regional transmission organizations, independent system operators, and exempt wholesale generators. The Commission is also revising its regulations to eliminate the requirement to submit FERC- 566 for public utilities that have not made any reportable sales under FERC-566 in any of the three preceding years. Further, the Commission is eliminating the requirement for public utilities submitting FERC-566 to identify individual residential customers by name and address.
