The three components detailed below will be added together to develop the new Schedule 42 rate. Step 1 — The capital component will be determined by multiplying an engineering estimate of the installed cost of the new light component, or fixture, by the Capital Recovery Factor of 10.952%. Step 2 —The maintenance component will either be the embedded maintenance cost of a similar existing fixture or an engineering estimate of the maintenance cost of a new fixture. The maintenance component for an existing light can be derived by subtracting the Schedule 46 (energy) light code monthly charge from the same Schedule 44 light code monthly charge (maintenance and energy) Step 3—The energy component will be the energy cost of the same wattage light under Schedule 46.

The three components detailed below will be added together to develop the new Schedule 42 rate. Step 1 -The capital component will be determined by multiplying an engineering estimate of the installed cost of the new light component, or fixture, by the Capital Recovery Factor of 10.952%. Step 2 -The maintenance component will either be the embedded maintenance cost of a similar existing fixture or an engineering estimate of the maintenance cost of a new fixture. The maintenance component for an existing light can be derived by subtracting the Schedule 46 (energy) light code monthly charge from the same Schedule 44 light code monthly charge (maintenance and energy). Step 3-The energy component will be the energy cost of the same wattage light under Schedule 46.
