Japanese Renewable Energy Industry’s First*¹ Solar-Powered Green
Data Center for GPU Cloud Services Achieves Stable Operations

Japan Renewable Energy Corporation (“JRE”; headquartered in Minato-ku, Tokyo; CEO:
Kazuhiro Takeuchi) is pleased to announce that stable operation has been achieved at
the data center constructed on the grounds of its solar power plant in Nagano prefecture,
thereby supplying computing power through 100% renewable energy. The data center
will be used by distributed cloud computing solutions provider Morgenrot Inc.
(“Morgenrot”; headquartered in Minato-ku, Tokyo; CEO: Hirotaka Inoue) to provide its
M:CPP (Morgenrot Computing Power Pool) GPU cloud service.
This project is based on the partnership between JRE and Morgenrot announced in thepress release dated June 27, 2022 (release), and is the first example of a renewableenergy provider in Japan launching a computing business located outside Japan’s large
metropolitan areas that is attached to a solar power plant. In December 2022, the data
center commenced commercial operation, primarily for CG rendering, and once stable
operation was verified, in April 2023 it was adopted for the M:CPP service, which
supports additional applications such as AI and simulation. This containerized datacenter accommodating 40 AMD and NVIDIA GPU servers installed within the JRE Nagano
Omachi Solar Power Plant in Omachi, Nagano prefecture, has to date achieved a highrate of capacity utilization and stable operations for a green data center with zero CO2emissions. The data center employs a “chiller-less” cooling system that uses water
drawn from a well for the server cooling equipment, with no need for the type of CFCs
that emit greenhouse gases. Thus, it operates as an environmentally-friendly andexceptionally energy-efficient installation (designed to deliver PUE [power usageeffectiveness] of 1.1*²).
Both JRE and Morgenrot will continue to work across industrial boundaries to construct
new business models that will lead to decarbonization of critical social infrastructure,
thereby using renewable energy for transitioning existing businesses to carbon-neutrality.

JRE will further promote renewable energy and related businesses with a mission to go
beyond kilowatt-hour-based value to create new service-based value by using renewableenergy not only for providing value in terms of power generated, but also for deliveringvalue-added services.
*1： The Japanese renewable energy industry’s first data center for GPU cloud services
constructed on the grounds of a solar power plant that emits zero CO2 (according toresearch by JRE)
*2：GPU servers generate a large amount of heat; however, efforts were made to curb
electric power consumption and conserve energy used for cooling and other purposesby designing the data center with a target PUE of 1.1. Measurements taken during theperiod when the entire site was comprehensively tested prior to the start of service,confirmed that pPUE (partial PUE, or PUE for the data center specifically) was at thetarget level.
PUE is annual energy consumption of the whole data center facility divided by annual
energy consumption of the data center’s ICT equipment
Annual energy consumption of the whole data center facility: The combined annual
energy consumption of the power inputs to the containers and the power input to thepump room
Annual energy consumption of the data center’s ICT equipment: The combined annual
energy consumption of the output PDUs (power distribution units) mounted on eachserver rack

About JRE
Founded in 2012 with a mission “Changing the world with renewable energy.” With theunderstanding of the local community, JRE currently has 95 renewable power
plants (including solar, wind and biomass) either in operation or under construction, plus
a number of large-scale offshore wind farms and other projects at the planning stage.
JRE is committed to addressing environmental and social challenges through renewableenergy and working towards a decarbonized and fully sustainable society.
