JERA Cross Launches Virtual PPA Aggregation Service for Sony Semiconductor Manufacturing 

— Aggregating Surplus Electricity from Rooftop Solar PV to Provide Long-term Environmental Value —

TOKYO — JERA Cross Co., Inc. (“JERA Cross”) today announced that on April 1, 2026, it began providing an aggregation service to Sony Semiconductor Manufacturing Corporation1 (“SSMC”) that bundles surplus electricity generated by rooftop solar PV systems installed across customer facilities and sites, and supplies long-term environmental value to SSMC through a Virtual PPA2 (“V-PPA”) (the “Agreement”).

Against the backdrop of initiatives such as RE1003 and SBTi4, demand for long-term renewable energy procurement is rising, particularly among large enterprises. However, the development of large-scale renewable power sources faces constraints including land availability and grid connection, and supply has not necessarily expanded sufficiently. At the same time, while urban rooftop solar PV represents a promising renewable energy resource, the small scale of individual installations has made it difficult to connect them to long-term contracts with major demand-side customers.

Under the Agreement, JERA Cross will aggregate surplus electricity and environmental value from rooftop solar PV systems located across Japan (excluding the Okinawa area). The surplus electricity will be supplied to the wholesale electricity market, while the environmental value will be provided to SSMC, contributing to SSMC’s long-term and stable procurement of environmental value.

Leveraging the characteristics of V-PPA, JERA Cross will be responsible for contract design, condition coordination, and performance management. Through this approach, environmental value generated by distributed rooftop solar PV systems — which have been difficult to utilize individually — is aggregated, enabling SSMC to secure it on a long-term basis.

Through the provision of environmental value under this Agreement, JERA Cross will support SSMC’s decarbonization, and contribute to the achievement of the Sony Group’s medium-term target of sourcing 100% of the electricity used at its own business sites from renewable energy by 2030.

Notes

*1   A company within the Sony Semiconductor Solutions Group responsible for the mass-production development and manufacturing of semiconductors.

*2   A contractual arrangement in which a corporate off-taker and a power generator trade environmental value derived from renewable energy on a long-term, fixed-price basis. No physical delivery of electricity takes place; environmental value is procured primarily through the settlement of price differences.

*3   RE100 is an international corporate initiative under which member companies commit to sourcing 100% of the electricity used in their business activities from renewable energy. Companies from around the world participate, setting and executing renewable energy procurement targets.

*4   SBTi (Science Based Targets initiative) is an international initiative that certifies whether companies’ greenhouse gas emission reduction targets are consistent with the level required by the Paris Agreement. It is operated by CDP, the United Nations Global Compact, WRI, and WWF.

*5   “24/7 (twenty-four seven) carbon-free electricity” refers to electricity that emits no CO₂ across all hours of the day, every day of the week — i.e., 365 days a year. In accordance with Japan’s Ministry of Economy, Trade and Industry “Guidelines for the Retail Electricity Sales Business,” the term denotes a supply scheme in which 100% of demand electricity is sourced from CO₂ zero-emission power sources (renewable energy generation facilities, hydrogen generation facilities, etc.) and supplied together with environmental value through the use of non-fossil certificates. It does not signify that no CO₂ is emitted across the full lifecycle, including fuel production and transportation.
