Case 09-E-____; Case 09-G-____ (NYSEG)DIRECT TESTIMONY OF THE CAPITAL EXPENDITURES,RELIABILITY, AND OPERATIONS PANEL12345678910111213141516171819202122Q. Are the estimated capital and O&M costs related to redefinition of bulktransmission included in the five year capital plan summarized in Exhibit __(NYSEGCRO-2), or in the Company's proposed revenue requirements?A. No. The cost estimates have been updated and presented to the Commission forits information.Q. In the event that the definition of bulk transmission is modified, will the Companyhave to recover the related costs?A. Yes. As the information presented to the Commission demonstrates, the costsassociated with such a redefinition will be significant and the Company will needtimely recovery of those costs once the standards and a timeline for compliancehave been approved.NYSEG O&M to Maintain Reliable ServiceQ. Can you briefly summarize the areas of increased O&M investments necessaryfor NYSEG to maintain safe and reliable service?A. Increased investment in distribution vegetation management, transmission rightof-waymaintenance, electric system maintenance, and human resources arenecessary to maintain safe and reliable service.Distribution Vegetation ManagementQ. Can you explain the Company's current distribution vegetation program?A. The Company has vegetation management programs to provide safe and reliableelectric service to its customers.

Case 09-E-____; Case 09-G-____ (NYSEG)DIRECT TESTIMONY OF THE CAPITAL EXPENDITURES,RELIABILITY, AND OPERATIONS PANEL12345678910111213141516171819202122system in accordance with established levels of service reliability. The Companyrecently filed a full description of its line clearing program in its ReportRegarding Line Clearance filed on August 24, 2009 in Case 09-E-0472.Q. Can the Panel please elaborate on the need for additional distribution vegetationmanagement?A. The Company currently performs scheduled cycle line clearance on three phaseportions of its distribution system. The balance of distribution circuit lineclearance is prioritized to maximize reliability impact. This approach has allowedNYSEG to achieve its established service quality levels (as measured by theCAIDI and SAIFI targets). However, establishing a full cycle line clearanceprogram for all distribution circuits would support continued reliabilityperformance and in the long run be most cost-effective. Lines on cleared ROWare less likely to sustain interruptions due to tree contact, and it follows thatclearing more ROW on a periodic basis will maintain or improve reliability.Cycle clearing ensures that ROW boundaries are well-established and maintainedon a regular schedule, providing consistent visibility and accessibility toinspection and repair crews. This allows for quicker identification and correctionof problems and facilitates preventive line maintenance. Cycle clearing alsoensures periodic identification and removal of danger trees along the ROW edge.Furthermore, cycle clearing enhances public safety by minimizing the risk thatvegetation will become energized, and lessens the system-wide potential forhuman contact with energized conductors. The reduction in vegetation size,54
