2014 Strategic Energy Plan The Government of Japan formulates the Strategic Energy Plan in order to show to the public the basic direction of Japan s energy policy under the Basic Act on Energy Policy. On April 11, 2014, the Cabinet decided to approve the new Strategic Energy Plan as the basis for the orientation of Japan s new energy policy, considering the dramatic changes in energy environments inside and outside Japan, including those caused by the Great East Japan Earthquake and the subsequent accidents at TEPCO s Fukushima Daiichi Nuclear Power Station. Strategic Energy Plan http://www.enecho.meti.go.jp/en/category/others/basic_plan/pdf/4th_strategic_energy_plan. pdf

2014 Strategic Energy Plan Section 3: Accelerating the introduction of renewable energy: Toward achieving grid parity over the mid-to long-term 1. Strengthening measures to accelerate the introduction of wind and geothermal power Regarding wind and geothermal power, which may be economically feasible depending on the scale of development, efforts will be made to resolve the many challenges involved in their introduction. Therefore, in order to smoothly and quickly introduce wind power generation facilities, efforts will be continued to accelerate environmental assessment and rationalize safety regulations under the Electricity Business Act.

Permits and Approvals for Wind Turbine In order to construct a wind farm, various permits and approvals are required from individual local authorities. The permits and approvals can be classified in the following 3 phases; 1.Locational survey phase (e.g. wind condition survey) 2.Execution design phase (applications related mainly to electricity) 3.Construction phase (e.g. Electricity Business Act, Industrial Safety and Health Law) Depending on the location of the site, additional permits and approvals may be requested by the local authorities.

Permits and Approvals for Wind Turbine 1. Permits and approvals in relation to the location a. Conversion of agricultural land permit 農 地 転 用 許 可 Applicable in case of using a farm land for constructing a wind farm b. Forest law 森 林 法 Require permit from the prefectural governor. As a general rule, for areas that are specified as Protection Forest, it is not possible to obtain the permit. c. Natural park law 自 然 公 園 法 In case of constructing a wind farm inside the national park, licensing system is applied in certain areas. In some area, it is not possible to obtain the permit.

Permits and Approvals for Wind Turbine 2. Permits and approvals in relation to design and construction a. Power connection contract 電 力 受 給 契 約 Require consultation with the electricity company regarding the gridinterconnection prior to the contract (not a requirement under the regulations) b. Certification of power generation using renewable energy power generation equipment 再 生 可 能 エネルギー 発 電 設 備 を 用 いた 発 電 の 認 定 To be applied prior to the power connecting contract. This can be obtained also before the start of construction. c.

Support structure of Wind Turbine according to Design Guideline for WTG in Japan Support structure of Wind Turbine shall satisfy the requirement of Ministerial Ordinance regarding Technical Standards on Wind Turbines (article 7) and its interpretation (article 7 to 15 and appended tables). Technical standard is based on the requirements of Building Standard Law. However additional environmental conditions of Japan, such as lightning and typhoon/turbulence need to be considered. NEDO (New Energy and Industrial Technology Development Organization) have been publishing Guideline for WTG, for Lightning and for typhoon / turbulence.

Support structure of Wind Turbine according to Design Guideline for WTG in Japan Lightning Altitude of thundercloud Flash Summer (Apr.- Oct.) High Negative Downward Winter (Nov. Mar.) Low Positive Upward Flash charge Low High >300C Derived from NEDO Guideline

Wind Turbine Support Structure Design according to Design Guideline for WTG in Japan Guideline proposes; When designing the Support Structure for a wind turbine, fatigue load which are caused by strong wind such as typhoon and rainstorm to be considered. In addition, abnormal loads and specific loading conditions based on IEC standards to be considered as well. Besides the wind related loads, specific environmental conditions in Japan such as the earthquake needs to be fulfilled. On the Building Standard Law, there is no clear statement mentioned regarding the fatigue strength. However it is necessary to secure the strength since the fatigue load due to external force will repeatedly affect the Support Structure. Dynamic Analysis and Structural Design of Wind Turbine Committee of Structural Engineering issued by the Japan Society of Civil Engineers 風 力 発 電 設 備 支 持 物 構 造 設 計 指 針 同 解 説 土 木 学 会 is used as a reference to design the Support Structure. This also covers the design of the foundation of the wind turbine.

Grid Inter-connection for Wind Farms Connection Obligations Priority / Congestion Control Wide Area Operation / Use of Interconnection Public Information Germany - As a general rule, connect all. Cost for expanding the interconnection is covered by the provider. However, if the extension is unreasonable economically, the provider has the right to refuse. - Output suppression for renewable energy is the lowest priority (comes even after nuclear energy). - Taking full advantage of renewable energy by communication line with the other districts through the market. - Interconnection internationally - Power transmission congestion status is available on Web. - If requested by the power producers, the power company is obliged to disclose the evidence in case of rejecting the interconnection. Japan - As a general rule, connection is obligation. However, it is accepted to reject the connection in case the amount of electricity is expected to exceed the limit. Cost for expanding the interconnection must be covered by the wind farm owners. - Renewable energy has priority over thermal energy but is suppressed before the long-term fixed power supply such as nuclear and hydro energy. - Controlled by the power company on a district base. - No communication line in between the districts. - No interconnections internationally. - The Power company has the obligation to disclose the evidence in case of rejecting the interconnection.

Grid Inter-connection for Wind Farms Procedures and discussion with the Electric Power Company Regulations regarding the grid-interconnection is not prescribed in the Electricity Business Act. It is only subjected to the discussion between the Electric Power Company and the wind farm installer. In the discussion, Guideline for Grid-interconnection Technical Requirements Concerning Electricity Quality 電 力 品 質 確 保 に 関 する 系 統 連 係 技 術 要 件 ガイドライン is used as the basis for the decision. Time required for the discussion is normally 1-2 months. It is recommended to go into this discussion at the early stage of planning the wind farm. Item Prior discussion Grid-interconnection application Contract Handover inspection Description Technical and commercial discussions to be held with the Electric Power Company on how to interconnect to the grid. After obtaining the provisional agreement, application form to be submitted to the Electric Power Company. Once an agreement is obtained from the discussion, contract to be signed. The Electric Power Company to perform the construction works in relation to the gridinterconnection. During the self-inspection at the completion of construction, Electric Power Company will inspect on site the points discussed at the prior discussion.

Grid Inter-connection for Wind Farms Points to be confirmed during the prior discussion (example) Wind condition data of the site for at least 1 year must be available. Research on environmental impact must be done and the solutions to the issues must be available. Permits and approvals required for the development to be well researched and there must be a high prospect in obtaining the permit. Negotiation with the land owner of the site must be under progress. Briefing concerning the project to be held for the neighborhood resident. Financing plan of the project must be available. Project schedule including the procurement of the wind turbine must be available.
