Yokohama Arena Inc. (Headquarters: Yokohama, Kanagawa, President: Hiromichi Murai, hereinafter 'Yokohama Arena Inc.') announces that starting April 2026, its multi-purpose facility 'Yokohama Arena' (located in Kohoku-ku, Yokohama, hereinafter 'Yokohama Arena') will begin utilizing renewable energy generated from solar power generation equipment installed on the roofs of Yokohama municipal schools by Tokyu Land Corporation (Headquarters: Shibuya-ku, Tokyo, President: Tatsuaki Tanaka, hereinafter 'Tokyu Land'). This power will be supplied via an off-site corporate PPA (hereinafter 'Off-site PPA') *1 scheme through Tokyu Land's wholly-owned subsidiary, Reene Co., Ltd. (Headquarters: Shibuya-ku, Tokyo, Representative Director: Keisuke Nishida, hereinafter 'Reene'), and used as part of the facility's electricity. Through this initiative, we will establish 'local production for local consumption,' effectively utilizing renewable energy born in Yokohama (hereinafter 'renewable power') within Yokohama, contributing to the realization of a decarbonized society in the city. Additionally, Tokyu Community Corp. (Headquarters: Setagaya-ku, Tokyo, President: Tomoyuki Hayakawa, hereinafter 'Tokyu Community'), which contracts the building management of Yokohama Arena, will strive to further improve the building's value by conducting appropriate energy management for the power supplied from Reene, in addition to the off-site PPA introduced this time, in its building maintenance and management.
*1 PPA stands for 'Power Purchase Agreement'. An off-site corporate PPA refers to a mechanism where renewable electricity is transported outside the premises of a renewable energy power plant and used.
Background
In the 'Yokohama City Global Warming Countermeasures Implementation Plan (City Hall Edition)', Yokohama City is promoting the introduction of solar power generation equipment as one of the proactive initiatives of the city hall. By utilizing the PPA business targeting 814 public facilities where installation is possible, it aims to achieve a 100% implementation rate by FY2035.
As part of this, the city has been promoting the introduction of solar power generation equipment via PPA targeting municipal schools since FY2021, and in January 2023, Tokyu Land was selected as the implementing operator for the second phase of the school PPA project.
Tokyu Land will sequentially install solar power generation equipment at a total of 43 municipal elementary, junior high, high, and special needs schools from FY2023 to FY2025, and supply the renewable power generated from the equipment for in-house consumption at the schools.
Details of This Initiative
This initiative supplies and utilizes surplus renewable power from holidays, etc., when schools are closed, targeting multiple schools in Yokohama, to 'Yokohama Arena' via an off-site PPA through the retail electricity provider, Reene.
This enables the realization of 'local production for local consumption,' where renewable power born in Yokohama is effectively utilized within Yokohama, and makes it possible for about 8% of the facility's annual electricity usage to be 'raw green power.'
Furthermore, for the electricity that cannot be covered solely by the off-site PPA, by supplying it with FIT non-fossil certificates *2 attached, we will make 100% of the facility's annual electricity usage renewable, contributing to the realization of a decarbonized society by 2050.
*2 'Substantial Renewable Energy Plan' (electricity menu) of 'Reene Denki' accompanied by FIT non-fossil certificates, which are the environmental value derived from renewable energy power plants developed using the FIT system. By utilizing FIT non-fossil certificates for the electricity sold by retail electricity providers to consumers, the reduction of CO2 emissions is recognized.

FAQ
What is an Offsite PPA?
It is a mechanism for transporting renewable energy electricity from outside the power plant site (offsite) to demand facilities and selling it through a power purchase agreement.
Will Yokohama Arena's power be 100% renewable?
Yes, in addition to the offsite PPA from schools, by supplying FIT non-fossil certificates, 100% of the annual electricity consumption will be from renewable sources.
What happens to the school's electricity?
On weekdays, it is supplied for self-consumption at the school, and during holidays when the school is closed, the surplus power is supplied to Yokohama Arena.
