If electricity from the power generation farm of 750m×1500m with 1.5m wave height that
is an ordinary environmental condition is sold for 27 \/kWh, the sales becomes about
13,000,000,000 yen a year. Then, when 10,000,000,000 yen is saved from sales of
13,000,000,000 yen a year for 15 years, it becomes 150,000,000,000 yen.
The power generation farm is composed of 12 power generation barges. Therefore, one power
generation barge becomes 12,500,000,000 yen. The power generation barge is composed of 20
power generation modules. Therefore, one power generation module is 625,000,000 yen.
One power generation module is made from 20 power generation units and the connecting
parts of the power generation unit. The connecting parts are two tension buoys and two
solid body bars. When it is assumed that the part cost of the connection is 100,000,000
yen, the budget of 20 power generation units becomes 525,000,000 yen. The budget of one
power generation unit becomes 26,250,000 yen. The power generation unit is composed of one
power generation buoy, the unit shroud assembly, the two gear-change assembly, and two
dynamos.
Actually, it costs the interest rate to the business fund. When the amount of the
refinements of 15 years is assumed to be 10,000,000,000 yen by the interest rate of 4% a
year, the capital of 111,110,000,000 yen is borrowed. Therefore, the power generation barge
is 9,250,000,000 yen. And the power generation module is 463,000,000 yen. The budget of one
power generation unit becomes 18,000,000 yen. This budget is very advantageous for the wave
activated power generation business.

要約すると・・・。
１．波高１．５ｍの海域でも、電気料金を２７円／ｋＷｈとすると、７５０ｍ×１５００ｍの面積
で約１３０億円の売り上げになりますね。
２．１３０億円の中から、１００億円を１５年貯金すると、１５００億円です。これを全額投資す
れば１５００億円ですが、世の中そんなに甘くなくて・・・。
３．年間返済額を１００億円として（ちょっと高めですが）金利４％で銀行に設備資金を申し込む
と、約１１１０億円の資金が借りられます。
４．これで計算すると・・・。
（１）発電ファームは１２艘の発電はしけで構成されます。発電はしけ１艘は、９２億５千万円で
製造することになります。
（２）発電はしけは発電モジュールが２０個ですから、発電モジュールの予算は４億６３００万円
になります。
（３）発電ユニットは剛体接続バーの費用を１億円として、発電ユニット１個が１８００万円と計
算されます。
５．波力発電の設備費用は企業秘密ですので、はっきりしたことはいえませんが、波高１．５ｍの
平凡な海域で使用するなら・・・。発電ユニットの予算が１８００万円は「余裕あり」でしょう
ね。この余裕十分な計画でも、年間３０億円以上の利益が確保されています。
