Exhibit A - Generator Maintenance Scope.xlsx

This is a generator maintenance scope of work document for multiple City of Madison agencies and departments. The document outlines comprehensive preventive maintenance requirements for 22 generators across various city facilities including sewer utility lift stations, parking garages, police and fire stations, engineering operations, streets department, and fleet services. The generators range from 20 kW to 650 kW in capacity, with fuel types including natural gas and diesel. Maintenance is organized into three service categories: Basic PM (preventive maintenance) performed twice yearly, Oil Analysis performed once yearly, and Load Testing/Major PM performed once yearly, with the Major PM service replacing one scheduled Basic PM in those years. The anticipated service schedule spans from 2026 through 2031, with generators stratified into three groups (A, B, C) based on major PM timing. Note that Bartillon and Truax generators are excluded from 2026 service and will receive only basic PM once that year.

The maintenance scope includes detailed inspection, lubrication, fuel system checks, cooling system maintenance, battery and electrical testing, exhaust system inspection, mechanical checks, and automatic transfer switch (ATS) testing. Major PM services include oil and filter changes, fuel filter replacement, coolant system flushing, load transfer testing with utility power failure simulation, and two-hour load bank testing at 25% increments up to 100% nameplate capacity. Four capacity tiers are identified: Tier 1 (Small, 0-100 kW) with 16 total generators, Tier 2 (Mid, 101-250 kW) with 3 generators, Tier 3 (Large, 251-500 kW) with 2 generators, and Tier 4 (Heavy, 501+ kW) with 1 generator. The scope specifies that load transfer testing requires coordination and advance scheduling with City Engineering, and all maintenance activities must be documented with recorded data including engine hours, pressures, temperatures, voltages, and frequencies.
