Partially Liberalized But Still Very Low Competition

3

While Japan’s electricity market has been partially liberalized since 2000, still big 10 EPCOs dominates the market. 10 big EPCOs: 848.5TWh / 209GW = JPY 18.2 trillion ($ 151.7bn, € 134.8bn) (2013)

Share of non- big EPCOs for over 50kW retail market = 4.2%

Only 1.3% is transacted at Japan Electric Power Exchange (JEPX)

Total market volume: 982.4TWh/289GW

Problems Revealed by 3.11

The Great East Japan Earthquake on March 11 2011 revealed negative aspects of regional monopoly system with 10 big and vertically integrated EPCOs. 1. Lack of system which transmits electricity beyond regions

2. Little competition and strong price control

3. Little flexibility in changing the existing energy mix; hard to

increase the ratio of renewable energy

Page 9: Japan's Electricity Market Reform and Beyong · PDF fileJapan’s Electricity Market Reform and Beyond . July 7, 2015 Takuya Yamazaki ... The Japan Atomic Co.-Tokai Daini Tokyo Electric

1st step: Establish the OCCTO Established the Organization for Cross-regional Coordination of Transmission

Operators (OCCTO) in Apr. 2015 OCCTO’s main functions include:

1. Review the EPCOs’ supply-demand and grid plans for changes in the plans (e.g. tie line construction) if needed.

2. Order EPCOs to increase power generation and interchange if supply gets tight.

2nd step: Full Retail Competition • Expand retail competition to the residential sector in 2016 • Maintain regulation on retail tariff for under 50kW users to incumbent 10 big EPCOs at

least until 2020

Will be liberalized

Page 11: Japan's Electricity Market Reform and Beyong · PDF fileJapan’s Electricity Market Reform and Beyond . July 7, 2015 Takuya Yamazaki ... The Japan Atomic Co.-Tokai Daini Tokyo Electric

3rd step: Unbundle Transmission/Distribution Sector

10

• Unbundle the big EPCOs’ transmission/distribution (T/D) sector by “legal unbundling” in 2020 to enhance neutrality and transparency of T/D sector.

• EPCO can choose either a holding company or an affiliated company format

Positive Signs of More Competition

Non-EPCO companies s announce to enter the power retail market after 2016 • Gas company : electricity + gas, • Telecom company : telecom + electricity, etc.

Big EPCOs announce to start preparing for offering power retail business in other

EPCOs’ regions.

Non-EPCO Companies start making new investments in power generation • KOBELCO: 1.4GW (2019-2020), Saibu Gas: 1.6GW (2020), Ohgishima Power:

0.4GW (2016), etc. EPCOs promote partnership

• Tokyo EPCO and Chubu EPCO contracted to form comprehensive partnership to jointly procure fuel, operate related businesses (upstream investment, transportation and trading), construct and replace thermal power plants, etc.

Policy Under Consideration

How can we secure stable supply and achieve desirable low-carbon generation mix while facilitating competition?

Challenges

Maintain nuclear power generation in competitive environments. Promote cross-regional electricity supply. Set up a scheme to recover investments in grid reinforcement for RES integration.

Policy Plan

Strengthen OCCTO’s influence over 9 TSOs to promote risk/cost sharing and coordination for more cross-regional transmission and grid reinforcement.

Prepare the scheme for neutralizing risks of nuclear investments Review FIT system. Introduce “Capacity Mechanism”

History of Electricity Market Reforms in Japan

No. Year enforced Overview

1 1995 • Opened the IPP (Independent Power Producer) market • Allowed specified-scaled and vertically integrated power generators

2 2000 • Introduced partial retail competition (over 2,000kW in 2000 [26%], over 500kW in 2004 [40%]) • Introduced regulation of third party access to grid lines

3 2005 • Expanded retail competition (over 50kW [62%]) • Established the wholesale power exchange (JEPX) and its supporting

body for transmission in wider areas • Improved regulation of third party access to grid lines, and

introduced accounting separation of transmission/distribution sector

4 2008 • Modified the rule of wheeling rates

No competition in the electricity market before 1995: 10 vertically integrated EPCOs dominated and controlled the market.

METI embarked on a series of reforms...

Improve liquidity in the wholesale market • Current rule (from March 2013):

• Self commitment by 10 big EPCOs to provide all capacity except for adequate reserve margin into JEPX

• Market monitoring by the regulator

• Further discussion including introduction of VPP scheme etc. will be needed depending on the result of market monitoring

Cross-regional competition • Avoid market separation and congestion of tie lines through OCCTO’s function for

reinforcing their capacities. Eg. Frequency conversion b/w Tokyo and Chubu : 1.2GW 2.1GW 3.0GW DC tie line b/w Hokkaido and Tohoku: 0.6GW 0.9GW ? ?

• Maintain the “postage stamp” cost allocation scheme for network fee, even after

introducing full retail competition.

Switching support system

• Establish an one-stop system for switching support until 2016. • New retailer X can obtain necessary customers’ information for the switching, which are

standardized, from TDSOs through the system. • New retailer X can complete a switching process including changing a wheeling contract b/w

retailer X and TDSOs through the system. • Time line: “automatically and instantly”

Ensuring electricity security in Japan’s EMR project

1. Regulation for T/D companies to secure frequencies and to maintain

investment on the grid

2. Obligation for all retailers to secure adequate capacity <2016> - Ensure procurement of enough quantity in the electricity market

3. Auction for the long-run generation capacity by OCCTO <2016>

- Prepare for the possible shortage of long-run capacity as a safety net for the electricity market

4. Further discussion on capacity mechanism (capacity market etc.) - Enhance the incentive to establish and maintain generation plant

• All retailers are legally obliged to ensure adequate capacity (incl. reserve margin) to match their demand.

• Government checks all retailers’ plans at both points of registering to enter the market and of submitting 10-year supply and demand plan each year

• TDSO will balance the gap b/w actual supply and actual demand in the imbalance mechanism.

The demand of each “Small and Medium-sized Enterprise” and “Low Voltage Consumer” is small. However, the number is large.

Based on the perspective of efficiency of Smart Meters as a supply and demand measure, a transition to Smart Meters for commercial-scale utility customers will be initiated first.

Smart Meters in high voltage sector (factories, etc.) are planed to complete installing in Japan until FY2016.

Smart Meters in low voltage sector (household, etc.) are planed to complete installing in Tokyo until the end of FY2020 and in Japan until the end of FY2024.

All EPCOs announced to exchange the current meters to smart meters promptly for consumers who want to install according to the introduction of HEMS, etc. or switch their retailers.
