RPS RPS ((RenewablesRenewables Portfolio Portfolio Standard)Standard) in Japanin Japan

What is RPS system ?

Issued in June 2002Put into force in April 2003

The system to introduce new energy certainly and cost-effectively

Eligible energy sources of RPSof RPS・Wind-power generation・Solar energy generation・Geo-thermal generation・hydraulic power generation (small and medium )

(×hydroelectric dam) (○hydraulic turbine )

・Biomass・waste combustion energy generation

(only the biomass incineration)

Page 25: Considering the New Energy introduction targetweb.econ.keio.ac.jp/staff/myamagu/seminar_www/2003...Waste combustion utilizationWaste combustion utilization No particular policy !!

Set the obligation to

the energy supplier

Must attain this obligation

To attain their obligation…

1. Generate new energy by themselves

2. Buy new energy that the other energy supplier generated

RPS systemRPS system

RPS is a way to attain the obligation cost-effectively

new energy ≠ renewable energy

• hydraulic power generation• geo-thermal generation

are renewable energy, but are not new energy.because they are not economically inefficient.

renewable energy= natural energy + recycled energynew energy= renewable energy - hydraulic power generation ーgeo-

thermal generation

No!

“The target should include the maximum amount of new energy available.”
