Electricity market reform

2015 2016 2017 ・・・ 2020

Enabling cross-regional coordination of transmission

Enhancing market competition under the surveillance

Full liberalization of retail market

Legal unbundling

Creating “Base-load market” Merit-order on cross-regional transmission

Challenges

More competition

… and social responsibility

“Capacity mechanism” & “Non-fossil credit market” Environment and renewables

Accounting rule retrofit & a new fund for 1F decom. Decommissioning

Steps of FR Development

Main points of the Decision - Japan will firmly maintain its nuclear fuel cycle policy and R&D of fast

reactor (FR)

- The Council on Fast Reactor Development will be established

- New strategy for FR development will be finalized by the end of 2016.

- Reviewing the role of FBR Monju that may lead to possible decommissioning will be finalized by the end of 2016.

Latest event March 30th 1st meeting to determine members &

topics for review

U.S. – Japan Cooperation

(Industrial Cooperation) Manufacturing Cooperation in the third country projects Bechtel’s participation to Horizon project in UK Exelon – JAPC cooperation on plant operation

(Decommissioning) Fukushima-Daiichi Other NPPs (eg. Energy Solution – JAPC cooperation) Forums for further cooperation (G to G Cooperation) US-JP Bilateral Commission on Civil Nuclear Cooperation R&D cooperation under the Bilateral Committee (eg. accident tolerant fuel, seismic analysis, test data exchange…)
