Tokyo Metro, J-POWER to Promote Decarbonization in Railway Operations

Tokyo Metro Co., Ltd., and J-Solar Co., Ltd., have concluded a virtual PPA (non-fossil certificate transfer agreement for renewable energy). A Power Purchase Agreement (PPA) is a contract in which power consumers directly purchase renewable energy from power generators. A virtual PPA is a means for consumers to procure only the environmental value of renewable energy generated at a dedicated power plant constructed offsite.

Through this contract, Tokyo Metro will receive environmental value with additionality equivalent to about 3.9 million kWh of energy generated annually as non-fossil certificates for 20 years from the Himeji Oshio Solar Power Station (maximum capacity: 1,999 kW). The power station is being developed by J-Solar Co., Ltd., a wholly owned subsidiary of J-POWER. This agreement is expected to reduce Tokyo Metro’s CO2 emissions by about 1,521 t-CO2 annually.

Tokyo Metro has set a long-term environmental goal, Metro CO2 Zero Challenge 2050 (Japanese only), and aims to reduce CO2 emissions from all Tokyo Metro Group operations by 50% by FY2030 (compared with FY2013) and achieve effectively zero emissions by FY2050. It has been introducing energy-efficient vehicles and environmentally friendly equipment. Tokyo Metro will continue to promote the use of renewable energy through various means including virtual PPAs to achieve its goals and contribute to the realization of a safe and sustainable society.
