Japanese Electricity
Market
M. Hossein Javidi
Iran Electricity Market Regulatory Organization &
Administrative Department for Electricity Market
Regulatory Board
http://www.iesrd.org
در كشور ژاپن در سال 1925و قبل از جنگ جهاني دوم تعداد 738
شركت برق وجود داشت .در سال 1939تجهيزات توليد و انتقال با
ظرفيتهاي بيشتر از حد مشخصي در شركت دولتي توليد و انتقال
برق ژاپن
( ).Japan Electrical Generation and Transmission Co
ملحق شدند و درطول دوران جنگ بقيه شركتهاي باقيمانده بداخل
اين شركت و نه ( )9شركت توزيع برق ملحق گرديدند.
بعد از پايان جنگ جهاني دوم و در سال ،1951ژاپن به 9ايالت (بعدا"
به 10ايالت افزايش يافت) تقسيم شد و يك سيستم ادغام شده شامل
توليد ،انتقال و توزيع در هر ناحيه تأسيس گرديد كه توسط
شركتهاي خصوصي مورد بهره برداري قرار گرفت .در بازار
امروز اين 10شركت بهمراه عمده فروشان برق و اعضاء جديد بدنه
اصلي بازار برق ژاپن را تشكيل مي دهند.
In Japan there are 10 private electric utilities, all vertically-integrated
(from generation to retail supply). They are all regional monopolies,
with their own franchise areas. Between generators, inter utility trade
is carried out to ensure security of supply.
There are three wholesale
suppliers of power
•The Electric Power Development
Co Ltd(EPDC)
• The Japan Atomic Power
Company (JAPC)
•The Joint-Venture Power Utilities.
DEMAND
Japanese electricity demand has shown a steady
increase from 1965 to 1998, with a 5.3
percent average annual growth (EDMC/IEEJ
2000).
ELECTRICITY SECTOR
RESTRUCTURING
Deregulation of the electricity sector began in 1995. The
Electricity Utilities Industry Law, the main legislation covering the
electricity industry, was amended as a result of a number of
pressures, including:
1)The global energy sector reform trend
2)The comparatively high electricity tariffs in Japan
3) The deteriorating load factor (due to a sharp increase in
demand in the summer).
1995 Amendment to the Electric Utility
Industry Law (EUIL), April 21, 1995
در بخش توليد برق ،به منظور داخل نمودن توليد كنندگان
جديد ،پيش نياز صدور مجوز براي توليد كننده هاي مستقل
( )IPPکه براي مصارف خودشان برق توليد مي نمايند ،حذف
گرديد.
مشتركيني كه برق مورد نياز خود را توليد مي كنند،
درحال حاضر اجازه دارند كه برق توليدي خود را از طريق
خطوط انتقال شركتها به محل ديگري منتقل نمايند.
سيستم جديدي در بخش خرده فروشي برق تشكيل گرديد
كه توليد بوسيله Co-generationونيز خرده فروشي برق
راممكن ساخت.
Outline of Regulatory
Reform in Japan
Outline of Regulatory Reform in
Japan
Japanese Electric Utilities have been generation
private companies for more than 50 years;
no generation privatization except for EPDC
deregulation-utilities favor
liberalization - new entrants favor
market restructuring - more neutrally
Electricity
1995 Amendment to the Electric
Utility Industry Law (EUIL), April
21, 1995.
1999 Amendment to the EUIL,
became effective on March 21,
2000.
Gas and Oil
1999 Amendment to the Gas Utility Industry
Law (GUIL), Nov 1999, increase
competition between gas and electric utilities
2001 Abolishment of the Special Law for
Supply Security of Oil, April, 2001, would
brought complete free competition of oil market
1999 Amendment to the EUIL, lunched
on March 21, 2000
Partially liberalized the retail supply
segment, permitting large-scale consumers
to choose their own electricity supplier for:
Those with demand of more than 2
megawatts and at the level of 20 kilovolts
or higher.
1999 Amendment to the EUIL, became
effective on March 21, 2000
Made the vertically integrated power
companies to establish separate accounting
systems for their generation and transmission
operations
promotes competition by permitting supplying
other region
1995 Amendment
Accelerated the competition among
IPPs
Electricity rates in 1996 were nearly 6.3
percent lower than the 1989 base rate.
In 1998, the average rate paid by residential
customers decreased by 4.5 percent over
the previous year, while that paid by
commercial and industrial customers declined
by 5.1 percent
Existing electric industries accelerate to
reduce their investment and debt assets
Feb 2001 :
TEPCO announce to halt their investment
on new plants for 3 to 5 years, and with cut
their annual investment as below 1000 billion
yen in 2001, first time since 1979
Series of halt of new power plants and
reduced annual investment
Mar 2001 : Kansai Power Co. reduced annual
investment by 10%, and delayed 3 new plants, stop
10 plants, and close 3 plants
Mar 2001 : Chubu Power Co. reduced annual
investment by 13%, and delayed and halt 5 plants
Mar 2001 : Tohoku Power Co. reduced annual
investment by 15%
Mar 2001 : Hokuriku Power Co. reduced annual
investment by 24%, and halt Takakura pumping dam
(Hokuriku Power)
Series of halt of new power plants and
reduced annual investment
Mar 2001 : Shikoku Power Co. reduced annual
investment by 20%,
Mar 2001 : Kyushu Power Co. reduced annual
investment by 8.4%, and halt 2 coal coal power
plants
Aug 2001 : Niigata pumping dam (EPDC)
However, only nuclear exempted from generation
suspending
Rapid increase of distributed generation
power supply companies in the field of
regulated market:
16 companies set up, consisting:
1. Independent : 7
2. Oil company : 1
3. Gas company : 1
4. Electric utilities : 7
Anyway, electricity market is starting to
change
A view from:
Competitive Industry
A View from Competitive
Industry
limited availability of and access to inputs for power
generation, including fuel, land, and generating assets;
lack of access to excess generation capacity;
transmission access issues, including pricing for
transmission service that may render retail supply by
new market entrants uncompetitive;
limited potential access to the power pool operated by the
vertically integrated electric utilities in Japan;
A View from Competitive
Industry
lack of unbundling of the vertically integrated electric
utilities;
lack of an independent regulator;
lack of an independent system operator; environmental
requirements (especially at the prefecture and municipal
levels) that delay power plant development and result in
high construction costs; and
local certification requirements for power generating
equipment that are based on safety rather than on
performance standards, and that differ from
international norms.
Remaining Issues toward
Sustainable Energy System
Tax reform both reviewing existing tax and introducing
environmental tax;
stranded cost, which might largely come from nuclear assets;
introducing promotion mechanism for renewable and
distributed energy system, which would compatible with new
electricity market;
introducing promotion mechanism for energy efficiency,
which would compatible with new electricity market
Lack of open and democratic policy process, which has long
been dominated by the bureaucracy (METI);
