■地盤調査・地質調査の例太陽光発電設備を設置するための地盤調査は、アレイ架台の自重が、一般住宅等（※１）にくらべはるかに軽いことや、一般建築や一般住宅等でみられる水準の地盤調査は大掛かりになることや費用面での負担が大きいことから、なるべく簡易的に地盤調査をおこない、基礎設計の資料とすることが好ましい。

The Japanese FIT law for promotion of RE has been revised in June 2016, and its relatedregulations have been also being amended. The objectives and points are as follows.
The objectives :1. Promotion of the well balanced variety of RE.2. Relief of the burden of the FIT cost over the people3. Using the renovation of the electric power system
to advantage in order to utilize the RE power.
The points :1. Rearrangement of not yet operated PV systems and renewal of approval systems2. Introduction of some check systems and mandatory requirements to promote
the long life operation of the RE system3. Cost effective introduction of RE by setting the cost targets and introducing the
bidding system for PV systems4. Setting FIT rates for coming years to promote some REs which take long time for
preparation5. The transmission operators take over the obligation to purchase the FIT power,
so that the RE power can circulate nationwide better than before
3.1 Renovation of the Japanese FIT system
22
Reference: METI WEB
Maintenance and inspection are important key roles for long life operation Good maintenance and proper inspections are obliged to the PV system owners according to
the revised FIT law and regulations including the guidelines for the planning the RE powergeneration.
【Guidelines for the planning for the RE power generations 】
The guidelines for the planning of the RE power generations are to be published for the all applicants of the RE power generations applied for the FIT system. The all applicants who are willing to apply the FIT to their own RE power generation projects shall plan their projects according to the said guidelines including a plan for the good maintenance and properly periodic inspections.
【Guidelines of the maintenance and inspections for PV systems 】
Maintenance and inspections are one of the key items to disseminate the long life PV systems.JPEA and JEMA worked on the project and have successfully published “The Guidelines of the maintenance and inspections for the PV system” since last Dec. 2016.
Important items in the amended regulations of the FIT

In Japan, the reform of the electric power system is proceeding toward the final stage of the unbundling the power companies in 2020.
The first stage （Apr. 2015）： Established OCCTOThe second stage （Apr. 2016）： liberalized the retail marketThe final stage （Apr. 2020）： Unbundling the power system
Japanese government consulting committee’s report has been issued Dec. 2016
Key points・Competitive new business・RE power promotion・Financial support for the decommission of the nuclear power plants
3.2 Reform of the electric power system
24“Electricity Market Reform KANTETSU Committee” Summary
Scheme Issue Plan
Creation of the Baseload Market
Occupied by the Major Electricity Companies
Open the market and welcome to new comers to use the Baseload generation
New Transmission Interconnection Rules including implicit auction
Occupied by the Major Electricity Companies (until 10 years later)
Electricity of lower cost is to be used through the new rules including implicit auction
Introduction of the Capacity Mechanism
Electricity of high cost is difficult to exist
Create the Capacity Market for retailers to buy KW
Creation of the Non-Fossil Credits Market
Non-fossil value of electricity is not recognized
Create the Non-Fossil Credits Market for retailers
Accounting measures to abolish nuclear powers
Not considered in the past Collet money through the new transportation service fare scheme
25Electricity Market Reform “KANTETSU” Committee
Planned Schedule
26Reform of the power system for PV
Critical points for the PV systems
I. Increase the interconnections
Flexibility of the power network is crucial point
II. Vitalizing the electricity wholesale market and circulating
the RE power in it
Utilizing the benefits from the wholesale markets, which can
provide the adjustment of imbalance and others.
III. Reform of the transportation service rules
Promoting the utilization of the local PV systems including
systems with the FIT term expired.
27I．Increase the interconnections and the flexibility
1. OCCTO revised rules applicable to use of the interconnections for more effective use by auction.
2. Effective use of the interconnections will result in lower curtailment of renewable energy.
3. “Connect & Manage” style should be adopted so as to reduce curtailment as little as possible.

系統利用の在り方：日本版”Connect and manage”？
第８回 系統WG資料より
In discussion of a METI Working Group, a Japanese style “Connect and Manage” case is introduced by an Electric Company, which is very practical in this country’s current circumstances.
29II． Vitalizing the electricity wholesale market
1. Vitalizing the electricity wholesale market is necessary. Only a few percent of total electricity consumption is under dealing in this country.
2. Establishing new demand and supply control system, including Nega-watt trade, DR (Demand Response), VPP(Virtual Power Plant) etc. as well as EV and Heat-pump system is essential.
3. Starting the Real-time Market for imbalance adjustment by market mechanism is desired.
・Trade of ＦＩＴ electricity in the Wholesale Market・Use of generation after ＦＩＴ duration（new scheme）・Better forecast and VRE trade in the Market
30III．Maintenance of Grid and Reform of the Transportation Service Rules
1. Effective use of existing grid should be realized on the “Connect & Manage” basis.
2. Grid Maintenance should be carried out in accordance with a well-designed, long-term plan and proper transportation service fee scheme.
3. Self and local consumption of RE generated electricity should be promoted to avoid congestion in the grid. Proper transportation service fee for this purpose is essential.

Explanation of main points of the Paris Agreement of COP21
CO₂ emission
Target
33A doubling of the renewable energy share in the global energy mix by 2030 would set the world on a path that could limit global warming well below 2 °C above pre-industrial levels by the end of this century, in line with what the countries have agreed in Paris at the COP21.（IRENA：Road map for renewable energy future 2016)
34MOE Long-term Low-carbon Vision
35Necessity of RE use
RE generation
CO2 free energy
Industrial use of energy makes production.
Home use of energy leads us to happy life.
Competency of effective use of energy is crucial.
No use of energy is non-sense.
We should use sustainable energies
Purpose of decarbonizing ・Ultra-high efficiency and saving energy・Promotion of electrification
society of use of electricity in every aspect
electrified transportation and heating system
・DE-carbonization of generationnon-fossil or CCS
New needs are foreseeable to promote DE-carbonization in various industries.
PV industries’ successive contribution
36For more use of solar generation
What is necessary to advance use of VRE including solar ?
Proposal to the scheme
・Use of the interconnections
・Strengthen the interconnections
・Vitalizing of electricity market
Electricity Reform
・Re-considering priority in case of curtailment
・New scheme to make use of RE generation after the FIT duration
Smart operation
・Forecasting technology
・Fair access to the grid
・stable operation of the FIT scheme
Solar Generation goes to new step
・Self consumption and local consumption
・Maintenance scheme for long term operation
