Maintenance Man-Hour Ratio

Data for the Test Year (October 1, 2019 through September 30, 2020) came from the SAP work management database implemented in February 2017 requiring this Business Objects Report.

The man-hours were provided for the following work order types:

Breakdown Maintenance (BD): Maintenance that is performed when the equipment has

failed and no longer performs the function that is was designed for.

Corrective Maintenance (CM): Maintenance that is performed when the equipment is

functional but has observed signs of improper operations. Equipment has something wrong,

but is still operating.

Preventive (Periodic) Maintenance (PM): Maintenance that is scheduled and performed on a

regular basis, and is either time or condition directed.

1. Run the Business Objects Report

a. Public Folders

b. SAP BW

c. SAP WAM

d. Corp

e. WAM Secured Reports

i. Maintenance Man‐Hour Ratio (Secured Report)


2. Run the report with the following parameters (this example captures the test year)

3. Copy the report to Excel Spreadsheet

a. Run a pivot table on the data


We need to filter WBS Hier. Lvl 2 to remove the hours from overhauls. Uncheck those events

that have an OM in the title (ex. CHC 2 OM: Cunningham 2)

Please validate this with the financial analyst in making sure this is true with overhauls.

4. Total the hours for the Plant as per the type of generation (coal, gas, CT) for breakdown,

corrective and preventive maintenance.

Schedule H-11.3 O&M Cost per MWh

The source for generation values in Schedule H-11.3 is the Southwestern Public Service Company

(“SPS”) NERC GADS database (Meridium). The source for cost values is from spreadsheets

prepared by Corporate Finance using Xcel Energy corporate databases.

Steam Power Generation (FERC Accounts)

Coal Units: Harrington & Tolk.

Gas Units: Cunningham 1&2, Jones 1&2, Maddox 1, Moore Co, Nichols, Plant X.

Operations costs included FERC Accounts 500, 502, 503, 504, 505, 506, 507, 508, and

509. Maintenance costs included FERC Accounts 510, 511, 512, 513, 514, and 515.

Other Power Generation (FERC Accounts)

Combustion Turbines (CT): Carlsbad, Cunningham 3&4, Jones 3&4, Maddox 2&3, Quay,

Riverview.

Other: Hale Wind, Celanese, Tucumcari

Operations costs included FERC Accounts 546, 548, 549, 550 and 550.1.

Maintenance costs included FERC Accounts 551, 552, 553, 554 and 554.1.

The general ledger data was used to sort expenses by plants and service organizations. An

allocation process was used to allocate service organization expenses to each plant. The data

was then summarized for each plant and the data was entered into the Schedule spreadsheet.

Generation data for the past five years and the Test Year (12 months ended September 2020) were

entered into Schedule H-11.3.

Using the generation and cost data in Schedule H-11.3, “Cost per MWh” was calculated for

Operations, Maintenance, and Total O&M. The information is sorted by Plant and grouped by

fuel type (coal, gas, CT, and other).
