JAPEX Started On-site PPA Supply of Renewable Electricity to a Group Company- To Supply Renewable Electricity from PV Power Plant on our Idle Property to a Group Company’s Site Japan Petroleum Exploration Co., Ltd. (JAPEX) has installed a photovoltaic (PV) power generation power
plant named “Mitsuke PV Power Plant” (hereinafter the “PV Plant”) in the site of our Mitsuke Production
Facility at Mitsuke City, Niigata, with the generation capacity of 250kW and started its operation today.
Electricity generated by the PV Plant is supplied to the Mitsuke Gas and Chemical Plant of JAPEX SKS
Corporation (hereinafter the “SKS Plant”), which is a wholly-owned subsidiary, in our Mitsuke Production
Facility site, using the on-site PPA(*1) scheme. Through this renewable electricity supply, SKS Plant will beexpected to reduce CO2 emissions by 176 tons per year.
JAPEX has formulated our group’s direction for carbon neutrality “JAPEX2050: Toward a Carbon-NeutralSociety” in May 2021. This direction sets our targets to achieve net zero of our own operations in 2050 and, forthe achievement in 2050, to reduce 40% of Scope1+2 GHG emission intensity by 2030, compared to fiscal 2019.
In this direction, we also commit to creating and expanding our businesses in the fields that contribute to net
zero society, such as renewable energy and CCS/CCUS(*2).
Particularly in the renewable energy field, the supply of electricity from non-FIT(*3) PV power plants isgaining momentum in the market, and there is an urgent need to strengthen ability to respond to new
schemes and systems. This PV electricity supply from the PV Plant to the SKS Plant is our first PPA projectbased on those backgrounds. Please refer to the appendix for the outline of the PV Plant.
Based on the viewpoints of the utilization of our group’s idle lands and the response to GHG emissions
reduction, we will proceed to implement more PV power generation plants for the JAPEX group and to expand
the electricity supply from renewable energy sources to our group’s operation site, including by off-site selfdelivery. Furthermore, we will consider utilizing accumulated expertise through these efforts for horizontal
expansion to the external off-site corporate PPA businesses.
JAPEX, cooperating with each group company, will aim to contribute towards carbon neutrality in 2050
through supply and its expansion of low-carbon electricity from renewable energy sources.
