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 depreciation rate stated as a percentage of original cost of depreciable property was as follows:

	2018		2017		2016
	Avg Rate		Avg Rate		Avg Rate
Electric Transmission	2.42	%	2.41	%	2.39	%
Electric Distribution	2.51	%	2.51	%	2.49	%
Gas Distribution	1.61	%	1.63	%	1.63	%

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 67 years

• nuclear generation assets—approximately 60 years

• pumped storage facilities—76 years

• solar assets—25 years
