6 Efforts of utilities on PV: current status Regulatory Framework FiT for surplus PV Power Compliance of RPS Introduction of PV power plant Promotion of customer-side PV Installation of PV system in their own facilities Green-Power Fund, subsidy for non-residential PV Large- scale PV projects 30 sites, 140 MW in total Promotion of all-electrified houses with PV system Demonstrative research International cooperation Grid stabilization International demonstration projects by NEDO (TEPCO, Shikoku, Kansai, Okinawa) Smart Grid Other projects

7 Feed-in Tariff for surplus PV power - Obligation to purchase surplus PV power by utilities since Nov Until the end of Oct 2009, utilities voluntary purchased surplus PV energy at the same price of retail electricity (Net Billing) - The enlargement of this scheme is under discussion in the diet (Gross FIT for non- residential application and other renewables) Source: METI FIT as of FY 2011 < 10kW PV: 42 yen/kwh < 10 kw - <500kW PV: 40 Yen/kWh Period: 10years

8 Regulatory Framework: Renewables Portfolio Standards (since 2003) Obligation on electricity retailors to use certain amount of electricity from renewables Achievement: In 2009, RE electricity supply doubled from 2003 METI decided to terminate RPS after implementing new FIT starts Renewables Portfolio Standards Act Goal & Target of Renewable Electricity ( 100GWh/year ) Goal Target (fiscal year) Source: METI

24 Issue 3: Energy Matster Plan to be revised Current Energy Master Plan: New construction of 14 nuclear plants by Meeting global challenges and securing energy futures- (Revised in June 2010)

25 New FIT program Passed the diet on Aug 26th The Cabinet approved the draft law on March 11th The draft law will be submitted to the Diet The bill passed the House of Representatives on Aug 23th The bill passed the House of Senetors on Aug 26th The comittee for seting FiT and purchase term will be established in this autumn New FIT program will start from July 2012 ( originally planned to start April 2012) Collection of surcharge will be postpond for 9 months in the earthquake & Tsunami damaged area

26 Current program (Net-export FiT) and new program Current program Eligible technology: PV only New program Eligible technology: all RE

27 Summary Utilities efforts on PV in Japan - Support PV under regulatory framework - Plans to install total 140 MW of PV power plants - Promote customer side PV system - Conducts demonstration projects Utilities facing power shortage issues after March 11 th New Energy Master Plan is under review New FiT will be start in July 2012 Hope PV will be the solution for the Future!
