It is estimated that the monthly addition for a standard household will range between ¥30 and ¥100.

The result of estimation for an addition per kWh shows that an initial addition will be ¥0.1/kWh and a monthly addition for a standard household will be ¥30 - 100.

* The estimates below indicate the amount of the entire purchasing cost, and thus, avoidable cost and the amount equivalent to the cost incurred before the fare revision have not been deducted. Therefore, the amount of PV surcharge will actually be lower than the figures listed below.

		Initial Period	In 5-10 years
Total Purchase		Approx. ¥80-90 billion/year	Approx. ¥180-300 billion/year
Monthly addition per kWh		Approx. ¥0.10/kWh	Approx. ¥0.15-0.30/kWh
Monthly addition for a standard household * Electricity consumption: Approx. 3,600 (kWh/year)		Approx. ¥360/year	Approx. ¥540-1,080/year
Monthly addition for industry as a whole * Electricity consumption: Approx. 360 billion (kWh/year)		Approx. ¥36 billion/year	Approx. ¥54-108 billion/year
Of which, the amount borne by industries with a large demand	* Electricity consumption: Approx. 282 billion (kWh/year)	Approx. ¥28.2billion/year	Approx. ¥42.3-84.6 billion/year
	(e.g.) Machinery * Electricity consumption: Approx. 72 billion (kWh/year)	Approx. ¥7.2 billion/year	Approx. ¥10.8-21.6 billion/year
	(e.g.) Steel * Electricity consumption: Approx. 36 billion (kWh/year)	Approx. Approx. ¥3.6 billion/year	Approx. ¥5.4-10.8 billion/year
	(e.g.) Chemicals * Electricity consumption: Approx. 30 billion (kWh/year)	Approx. Approx. ¥3 billion/year	Approx. ¥4.5-9.0 billion/year
Of which amount borne by small- and medium-sized enterprises	(e.g.) Small restaurants * Electricity consumption: Approx. 8,400 (kWh/year)	Approx. ¥840/year	Approx. ¥1,260-2,520/year
	(e.g.) Small- and medium-sized factories * Electricity consumption: Approx. 0.3 million (kWh/year)	Approx. ¥30,000/year	Approx. ¥45,000-90,000/year

* The estimation for both standard households and industries with large demand is performed on the basis of the current consumption
* Compiled on the basis of Electricity Demand in FY 2008 (Confirmed Report) by the Federation of Electric Power Companies of Japan (April 30, 2009)
