Depreciation Rate Stated Percentage

PSE&G calculates depreciation under the straight-line method based on estimated average remaining lives of the several classes of depreciable property. These estimates are reviewed on a periodic basis and necessary adjustments are made as approved by the BPU or FERC. The average depreciation rate stated as a percentage of original cost of depreciable property was as follows:

	2020		2019		2018
	Avg Rate		Avg Rate		Avg Rate
Electric Transmission	2.41	%	2.41	%	2.42	%
Electric Distribution	2.55	%	2.54	%	2.51	%
Gas Distribution	1.84	%	1.85	%	1.61	%

PSEG Power calculates depreciation on generation-related assets under the straight-line method based on the assets’ estimated useful lives. The estimated useful lives are:

•general plant assets—3 years to 20 years

•fossil production assets—30 years to 56 years

•nuclear generation assets—approximately 60 years to 80 years

•solar assets—25 years to 35 years
