Required Sections of Annual Reliability Metric Report Filed Pursuant to Sections 8 and 9 of 17.9.589 NMAC

1. Executive Summary:

Please provide a narrative to illustrate the current state of distribution reliability and major trends.

2. How the Utility Measures Reliability:

Please provide a narrative that describes, in general terms, how the utility's measures and documents reliability matters, including examples of metrics that are most useful.

3. The Utility's Service Territory Map with Districts:

Maps should show how the utility operations are divided into geographic regional/divisions. Color coding may be useful to identify districts with above or below average reliability outcomes.

4. Reliability Indices IEEE 1366 for the Last 10 years (Excluding Planned Interruptions):

Tables are required. Charts to illustrate the data would be helpful. Distribution includes distribution lines; substation includes distribution substations; and transmission includes transmission substations and lines.

9. Narrative on Customer Complaints to the Utility About Interruptions:

The narrative shall provide the total number of customer complaints received by the utility about interruptions, as well as an overview of the types of those complaints. Reporting regarding the complaints shall be disaggregated by customer class or voltage level (large customers, residential, etc.) to the extent possible while not identifying individual customer data or disclosing confidential customer information. The narrative is not required to discuss individual customer complaints and what was done to resolve them; however, the utility may choose to include this information for illustrative purposes.

10. Trends of Investment in Transmission and Distribution System (CapEx and O&M) Over 10 Years of Spending on Reliability Improvements:

Please clarify whether all of your transmission is considered part of the bulk electric system as defined by the Federal Energy Regulatory Commission. If a portion of your transmission system is not considered a part of the bulk electric system, expenditures for each portion of the transmission system should be reported separately.

Table 10.1: Total Transmission O&M and Capital Expenditures

Transmission Expenditures	YR-9	YR-8	YR-7	YR-6	YR-5	YR-4	YR-3	YR-2	YR-1	YEAR
