1/ Where no depreciation rate is listed for a transmission or general plant account for a particular project,

NYPA lacks depreciable plant as of 12/31/2019 or 2020 (or all plant has been fully depreciated). If new plant corresponding to these

accounts is subsequently added for the relevant projects, the "New Project" depreciation rate for the relevant account will apply.

2/ New Project transmission and general depreciation rates are equal to the life of the asset adjusted for salvage.

3/ In the event a Contribution in Aid of Construction (CIAC) is made for a transmission facility, the transmission

depreciation rates above will be weighted based on the relative amount of underlying plant booked to the accounts

shown in lines 1-9 above and the weighted average depreciation rate will be used to amortize the CIAC. The life of a

facility subject to a CIAC will be equivalent to the depreciation rate calculated above, i.e., 100% deprecation rate = life

in years. The estimated life of the facility or rights associated with the facility will not change over the life of a CIAC

without prior FERC approval.

4/ NYPA has replaced the anomalous rates for these assets with New Project rates.

These depreciation rates will not change absent the appropriate filing at FERC.
