System Assessment Project Status Update

Phase one: relay setting comparison

• All contract engineer reports have been reviewed and no additional corrective actions have

been required.

• At Newport, additional documentation effort is required before a contract engineer is able to

perform the comparison. Phase two: record drawing review

• Contract engineer reviews have been completed on thirteen stations, with VELCO

acceptance review completed on the same thirteen stations.

• Newport has been added as a station requiring drawing review and will require an additional

effort to prepare the documentation before engaging the contract engineer. Phase three: relay setting basis

• Anticipated completion of contract engineer reviews for the Vernon & VY areas is in

September, and the anticipated completion of the Essex area is in July.

• It was identified the cross tripping of 345kV A & B systems does not meet NPCC
• requirements. VELCO is in the process of making design enhancements and will be

establishing a corrective action plan for systems that are already in service. Phase four: line testing

• Fourteen of thirty-four lines have been tested. Summary reports are still pending from the

contract engineer.
