J-POWER Group Environmental Vision

J-POWER Group and the Environment

To carry out environmental conservation activities across the Group as a whole, we have set forth the J-POWER Group Environmental Vision. We will contribute to the sustainable development of Japan and the world as a company involved in the supply of energy, while seeking harmony with the environment.

J-POWER Group Environmental Vision

The J-POWER Group Environmental Vision is based on the J-POWER Group Environmental Basic Policy and the Action Programs, and the Action Programs are composed of the J-POWER Group Environmental Action Guidelines, which are formulated every year, and the corporate targets and segment targets.

J-POWER Group Environmental Vision: Corporate Targets and 2020 Achievements

In fiscal 2020, we achieved all of the items covered by our Corporate Targets.

Addressing Global Environment Issues

Steadily implement the following measures aimed at realizing a low-carbon society as well as contribute to the stable supply of energy and reduction of CO2 emissions in Japan and around the world by achieving the targets of the Electric Power Council for a Low Carbon Society’s Action Plan for Achieving a Low-Carbon Society.

Item Target Main Fiscal 2020 Initiatives Status of
Target
Achievement
Promotion of
carbon reduction
and technological
development in
power generation		 1. Expansion of renewable energy
• Advance the new installation,
upgrading, and equipment
replacement of hydroelectric
power plants in order
to expand the use of
hydroelectric power.		 In our expansion of hydroelectric power utilization,
in February 2021 we increased the output of
Ashoro Hydroelectric Power Station Unit No. 2
through comprehensive renewal of its primary
facilities, and began operations at the station.
However, we plan to transmit the increased output
at a time when the available capacity of the grid
can be used in the future.
We also moved forward with construction on the
Shinkatsurazawa Hydroelectric Power Plant
Project.		 〇
• Work to significantly expand
wind power facilities, including
offshore wind power
generation.		 In onshore wind power, in December 2020 we
started operations at the Kuzumaki No. 2 Wind
Farm. We also moved forward with construction of
Kaminokuni No. 2 Wind Farm, with the Tomamae
and Shimamaki replacement projects, and with
preparations for construction of the Minami Ehime
No. 2 project.
In offshore wind power, we are advancing business
feasibility studies related to the Hibikinada. We
also proceeded with development surveys for the
Hiyama, Awara, and Saikai projects, and formed a
consortium for the Akita Prefecture offshore area.
In the overseas wind power business, in August
2018 we acquired a stake in the Triton Knoll
Offshore Wind Power Project in the U.K. We moved
for- ward with construction of this project,
aiming to begin operations during fiscal 2021.		 〇
• Work to develop new
geothermal power projects in
Japan.		 Looking at the development of new geothermal
power projects in Japan, we started operations of
the Wasabizawa Geothermal Power Plant in May
2019 and continued stable operation. We also
started construction of the Appi Geothermal Power
Plant in August 2019 and proceeded
the construction. In addition, at the Takahinatayama
site in Osaki City, Miyagi Prefecture, in July 2019
we began small caliber well drilling surveys aimed
at future geothermal power plant development.
Furthermore, having shut down the Onikobe
Geothermal Power Plant’s existing facilities in April
2017, we began the construction of facility
replacement in April 2019.		 〇
2. Strive toward carbon reduction and zero emissions in coal use
• Advance the development of
high-efficiency integrated coal
gasification combined
cycle (IGCC) technology with the aim
of bringing it to practical use.
Advance research and devel-
opment of CO2 capture,
utilization and storage (CCUS)
technology.		 At the Osaki CoolGen Project, we undertook
demonstration tests of oxygen-blown IGCC with
CO2 separation and capture (Phase 2) from
December 2019. We also started construction
preparations for demonstration tests of oxygen-
blown IGFC with CO2 separation and capture
(Phase 3) and for CO2 liquefaction process
demonstration.		 〇
• Work to replace aging coal-
fired thermal power plants
with the world’s leading high-
efficiency coal-fired thermal
power plants.		 In the Takehara Thermal Power Plant Replacement
Project, we began commercial operation of
Takehara Thermal Power Plant New Unit No. 1 in
June 2020.		 〇
• Promote the mixed
combustion of biomass fuels
in coal-fired thermal power
plants (effec- tive exploitation
of untapped resources).		 At the Matsuura Thermal Power Plant, Takehara
Thermal Power Plant, and Takasago Thermal
Power Plant, we implemented mixed combustion
using domestically-sourced biomass fuels (such
as wood pellets and dried sewage sludge).
Also, as preparation for large-scale mixed
combustion of wood pellets at the Takehara
Thermal Power Plant, we promoted initiatives to
secure fuel such as unused offcuts from forested
areas in Japan.		 〇
• Contribute to the reduction of
global CO2 emissions and the
adoption of advanced technol-
ogies by expanding the coal-
fired thermal power generation
business using J-POWER’s
advanced, high-efficiency
power generation
technologies, especially in
Asia.		 In Indonesia, we started trial operation of the
Central Java Project in preparation for starting
operations.		 〇
3. Promotion of the Ohma Nuclear Power Plant Project, with safety as a major prerequisite
• Advance construction of the
Ohma Nuclear Power Plant,
giving highest priority to safety
and working to ensure the
trust of the local community.		 For the Ohma Nuclear Power Plant Project, we
carried out studies for safety enhancement
measures and responded to the review of
compliance with the new safety standards. We
also implemented initiatives to gain the
understanding and trust of local residents.		 〇
Item Target Fiscal 2020 Performance & Evaluation Status of
Target
Achievement
Total thermal
efficiency for
thermal power
generation
(HHV, gross
efficiency)		 Maintain current level
[about 40%]		 40.9%(Reference: LHV = 41.9%)
[Fiscal 2019 Performance]
40.8%(Reference: LHV = 41.9%)

The J-POWER Group met its target for total
thermal efficiency for thermal power thanks to
efforts at existing thermal power plants to
maintain high-efficiency operations and to adopt
high-efficiency technologies when renovating
facilities.		 〇
Reduction of
sulfur hexafluoride
(SF6) emissions 
(Improvement of
recovery rate
during inspection
and retirement of
equipment)		 Inspection: at least 97% 
Retirement: at least 99%		 Inspection:99.7% Retirement: 99.2%
[Fiscal 2019 Performance]
Inspection: 99.9% Retirement: 99.3%

The target was met, with a recovery rate of 99.7%
during inspections and 99.2% at retirement, thanks
to efforts to curb emissions during equipment
inspection through sound recovery and reuse.		 〇

As a result of efforts including fuel management,
combustion management and the appropriate operation
of flue gas denitrification systems, we curbed our NOx
emissions and achieved our target for emissions per unit
of electric power generated.		 〇
Increasing the
recycling rate for
industrial waste		 Maintain current level
[about 97%]		 99.2%
[Fiscal 2019 Performance]

We achieved our targets through efforts to promote the
recycling of coal ash and to reduce industrial waste
generated by the maintenance and operation of power
plants.		 〇
Preservation of
aquatic
environments		 Consider the
protection of river and
ocean environments
in business activities		 Practiced consideration for the protection of river and
ocean environments

• At operating power generation facilities that are
involved with rivers, we implemented measures for the
protection of the river environment appropriate to the
conditions at each location. These included the
implementation of sedimentation disposal measures and
measures to mitigate the long-term persistence of
turbidity.
• At operating power generation facilities that adjoin the
ocean, we implemented precise control over effluent in
compliance with environmental protection agreements
and other such arrangements.		 〇
Preservation of
biodiversity		 Consider the
protection of biodiversity in
business activities		 Practiced consideration for biodiversity

We showed consideration for
the protection of ecosystems and the diversity of species in conducting
our business activities and worked to protect rare animal
and plant species and their habitats.		 〇
