1 PV in Japan and Utility s activities PV &Utility Workshop, ASEAN POWER WEEK 2015 IEA PVPS Expert, Japan RTS Corporation, Tokyo kaizuka@rts-pv.com

2 Contents Energy and PV status in Japan Utility companies activities on PV Challenges: grid connection Outlook Based on National Survey Report Japan 2014 (published in July 2015)

3 Electricity mix in Japan Hydro Coal Nuclear Gasoline, LNG Renewable Energy Electricity charge Share of base load Source: ANRE, METI First nuclear power reactor in Sendai Nuclear Power Plant started operation on August 11th First case in 2 years.

4 Trends of PV installed capacity in Japan (DC-based) 2015 market : similar level of 2014 Installed capacity in 1Q2015: ~2.7 GW (AC) Source: : IEA PVPS, : RTS 4

5 Companies in Thailand invest PV business in Japan Plans 3 projects (25 MW) with Japanese companies Develops large scale PV projects Jointly invest in solar farms in Japan Plans to develop 300 MW with Japanese company

6 IEA INTERNATIONAL ENERGY AGENCY PHOTOVOLTAIC POWER SYSTEMS PROGRAMME PV contributes >2% in 2014 Source: IEA-PVPS 出典 :IEA PVPS, A Snapshot of Global PV:Trends in Photovoltaic Applications

7 Overview of Utility Companies - 10 electric utility companies - Each company has its own service area - Investor owned - Conducting vertically integrated business (Generation, transmission and distribution)

8 Utilities activities for PV Started to show PV contribution for their supply and demand outlook in demand and supply outlook for the government Started to disclose grid connection status due to grid constriction issues Installing total 140 MW of PV systems in 30 sites Some companies promotes customer side PV to promote 100% electrification houses R, D&D for grid stabilization with storage, forecasting, etc. Subsidiaries are active in EPC or IPP business Solar IPP:Kanden Energy solutions,kyuden Mirai Energy, etc. EPC: Kandenko, Kyudenko, etc.

9 PV contribution analyzed by companies Power supply capabilities of PV systems in the summer by electric company (MW) Electric company Purchase of surplus PV power Hokkaido Tohoku Tokyo Chubu Kansai Hokuriku Chugoku Shikoku Kyushu Total Purchase of PV power (100 % from facility) Utility s own PV facilities Total estimated installed capacity Estimated supply capability Source: Electricity Supply-Demand Verification Subcommittee under METI (April 2015)

10 PV contribute more than 6.5% in this summer PV power generation capacity contributed more than >6.5% in this summer (total of 8 electric companies) Nuclear : 0% Thermal: 75.4% Hydro: 6.9% Pumped hydro: 10.9% PV 6.5% Other R Tokyo Shinbun, August 29 th 2015

11 Challenges Approved capacity for the FIT program reached > 80 GW RTS Corporation FIT < 10kW 42 Yen/kWh 38 Yen/kWh 37 Yen/kWh 10kW or more 40 Yen/kWh 36 Yen/kWh 32 Yen/kWh Source: RTS Corporation, PV Activities in Japan and Global PV Highlights 11

12 Grid connection issues raised - Kyusyu Power announced suspension of new grid connection contract in September Other company followed - METI studied maximum grid connection capacity for 7 companies (Prof. Kazuhiko Ogimoto lead the committee) - METI implemented new curtailment rules from January Utilities started disclose status of grid connection

13 Hosting Capacity by utility as of Nov utility companies implement extensive curtailment

14 Some changes on curtailment under the FIT program Item Former rules Output curtailment (From Jan 26, 2015) Period of output curtailment without compensation (From Jan. 26, 2015) Obligation to install remote controlling function for inverters (From Jan. 26, 2015) kw and more - Up to 30 days]/year - No - 7 utility companies can implement curtailment for <50 kw systems in service - (Output curtailment is applied to <10 kw systems only when curtailment by 10 kw systems is not enough, only for surplus electricity.) - Up to 360 hours/year (shifting from daily basis to hourly basis) - Yes - 2 levels of FIT in different electricity companies Source: RTS Corporation, PV Activities in Japan and Global PV Highlights 14

15 Outlook: Electricity market reform by 2020 Phase Year Summary Plan - Development of nation-wide plan of demand/ supply and grid First phase 2015 Establishment of widearea coordinating body - Wide-area operation across the service areas of ordinary times - Instructions to supply electricity regardless of the demand control and service areas at the time of disaster - Acceptance of interconnection of new power sources and disclosure of grid information Second phase 2016 Deregulation for retail market, residential sector - Consumers have the freedom to choose electric companies and prices - Institutional revision of regional monopoly by major electric companies Third phase Separation of electrical power production from power distribution and transmission, removal of price regulation - Separation of power distribution and transmission from electric companies - Remove retail price regulation in order to decrease the electricity price based on competition principle

16 METI released Long-term energy supply-demand outlook toward FY 2030 Renewables > nuclear power

17 PV in FY 2030 under the long-term energy supply-demand outlook Segment Power generation volume (TWh) Power generation capacity FY 2030 Ratio FY 2030 Share FY 2013 FY 2030 Residential % 7.6GW 9GW Non-residential % 13.4GW 55GW Subtotal % % 21GW 64GW - METI s outlook (not target) for see 64 GW in FY Outlook will be revised every 3 years:pv ratio has chance to be raised more due to tighter safety codes for restarting nuclear power plants Utilities need to prepare the market reform and accepting more renewables Shift to rooftop market (commercial & residential) needs to further dissemination of PV
