May 8, 2024
Mitsui Fudosan Residential Co., Ltd.
TEPCO Energy Partner, Inc.
Tokyo, Japan, May 8, 2024 - Mitsui Fudosan Residential Co., Ltd., a leading global real estate company headquartered in Tokyo, announced today that it has embarked on a new initiative with TEPCO Energy Partner, Inc. that will involve making the Enekari Plus solar power service available to newly built condominiums.
Whereas TEPCO Energy Partner has been introducing the Enekari Plus service to single-family homes, low-rise rental housing and other such dwellings in the Tokyo metropolitan area since February 2022, this initiative marks the first time that it will introduce the Enekari Plus service to newly built condominiums in the Tokyo metropolitan area.
The two companies will introduce the Enekari Plus service to the two properties PARK HOMES Yoyogi Nishihara and PARK HOMES Kami-Itabashi ahead of mandated installation of solar power equipment and other such devices in newly built residences in Tokyo effective from FY2025. Going forward, the two companies will also incrementally extend introduction of the Enekari Plus service to newly built condominiums of Mitsui Fudosan Residential.
Under this initiative, Mitsui Fudosan Residential will act in partnership with TEPCO Energy Partner from the design and construction phases with respect to newly built condominiums developed by Mitsui Fudosan Residential in the Tokyo metropolitan area, thereby enabling service subscribers to have solar power systems installed at zero initial cost while also providing them with access the service at a fixed monthly rate*. Also under this initiative, access to solar-generated renewable energy will be provided in the common area of PARK HOMES Yoyogi Nishihara and in one residential unit of PARK HOMES Kami-Itabashi. The service for enabling access to solar-generated renewable energy in common areas reduces the utility cost burden incurred by resident and also enables residents to gain access to electric power during power outages in order to recharge their smartphones and other devices, for instance, given that the service involves equipping common areas with emergency power outlets. Meanwhile, the solar power generation equipment is to be transferred to service subscribers free of charge upon expiration of the 15-year subscription period.
Mitsui Fudosan Residential and TEPCO Energy Partner will continue to actively engage in efforts that help give rise to a carbon-neutral society by extending renewable energy access to newly built condominiums.

■Sustainability in the Mitsui Fudosan Group
Based on the meaning of its “& mark,” “to generate new value with society through cooperation, coexistence and co-creation, we forge ahead, innovating,” the Mitsui Fudosan Group views the “creation of social value” and the “creation of economic value” as two wheels of a cart. Accordingly, we believe that the creation of social value leads to the creation of economic value, and that this economic value then creates even greater social value.
Moreover, we identified six Group Materiality priority issues when formulating our new management philosophy in April 2024. These Group Materiality priority issues are (1) Contribute to industrial competitiveness, (2) Coexist with the environment, (3) Health and Vitality, (4) Safety and security, (5) Diversity and inclusion, and (6) Compliance and governance. The Mitsui Fudosan Group will work to address each of the materialities through its core business activities and contribute to the promotion of sustainability.
