UPDATER Launches Cloud-Based Power Generation Service “Peepa” Using the Nature-Coexistence “HagaHaga Nature Power Plant”

UPDATER, Inc. (Head office: Setagaya-ku, Tokyo; Representative Director: Eiji Oishi), which aims to update society through lifestyle choices, will begin offering the cloud-based power generation service “Peepa” through its 100% renewable energy electricity service “Minna Denryoku.” The service uses the “HagaHaga Nature Power Plant” in Haga Town, Tochigi Prefecture, a nature-coexistence power plant designed to balance biodiversity conservation and climate action, in partnership with the Nature Conservation Society of Japan (NACS-J). This initiative is the fifth installment of the “Peepa” series and one of the “Coexisting Renewable Energy Project 10” initiatives, which aims to create 10 nature- and community-coexistence power plants across Japan by fiscal 2028. It is also the first concrete measure※2 based on the agreement signed with NACS-J in February 2026. “Peepa” is a subscription service that lets customers contract monthly for sections of solar panels in remote locations and use the generated electricity at home. It provides a new electricity option for people who cannot install solar panels, such as apartment residents, enabling them to choose renewable energy that coexists with nature and local communities. Background: While the adoption of renewable energy is rapidly advancing as a climate change measure, the impact of such development on local natural environments, ecosystems, and cultural landscapes has become an increasingly visible issue. Against this backdrop, UPDATER launched the “Coexisting Renewable Energy Project 10” in September 2025, following the certification of an area including agrivoltaic solar power in Toyooka City, Hyogo Prefecture, as Japan’s first “Nature Coexistence Site.” The project aims to create 10 nature- and community-coexistence power plants nationwide by fiscal 2028.※3 As part of this initiative, UPDATER signed a partnership agreement with NACS-J in February 2026 and is jointly studying what “nature-positive renewable energy” should look like, balancing the expansion of renewable energy with biodiversity conservation.※2 The HagaHaga Nature Power Plant is the third case under the project and the first attempt to examine the future form of renewable energy together with NACS-J. Using farmland in Haga Town, Tochigi Prefecture, the project implements agrivoltaic solar power, or solar sharing, to balance agriculture and power generation while aiming to coexist with the natural environment. It simultaneously produces crops and renewable electricity while conducting regular surveys and verification to maintain habitats for diverse species such as insects and birds around the power plant. UPDATER believes that the perspective of “how renewable energy is produced” will become increasingly important. As environmentally destructive forms of renewable energy have drawn attention in recent years, demand is growing among companies and consumers for power source choices that emphasize quality and the right approach. ※1 By combining electricity derived from renewable energy with the environmental value of non-fossil certificates designated as renewable energy, UPDATER supplies electricity that is 100% renewable, with zero CO2 emissions. ※2 Minna Denryoku｜UPDATER and the Nature Conservation Society of Japan Sign Partnership Agreement to Pursue Both Nature Positive and Carbon Neutral Goals｜February 2026｜https://minden.co.jp/news/2026/02/19/10321 ※3 Minna Denryoku｜UPDATER Launches New Project to Create 10 Nature- and Community-Coexistence Power Plants by Fiscal 2028｜September 2025｜https://minden.co.jp/news/2025/09/30/10092 About the HagaHaga Nature Power Plant: The HagaHaga Nature Power Plant is an agrivoltaic solar power plant located in Haga Town, Tochigi Prefecture.

Registration URL: https://forms.gle/zQNF9sLRbknJJThq9 About Peepa cloud-based solar power generation: Peepa is a service for individuals that lets customers contract for sections of remote solar panels for a monthly fee and use the generated electricity as their home electricity. It allows people such as apartment residents who cannot install solar panels at home to easily use electricity they effectively generate themselves. Features: No initial cost or construction required; applications can be completed online in a few minutes; matched electricity can be used almost free of charge※4; surplus electricity is purchased at market-linked prices※5; the fixed monthly subscription, or PPA, model helps stabilize household energy costs by reducing exposure to market price fluctuations. With Peepa, electricity usage and generation are matched every 30 minutes, and the matched portion can be used almost free of charge※4. Any generated electricity that is not matched and becomes surplus is purchased by Minna Denryoku at market prices※5 and deducted from the monthly electricity bill※6. ※4 Wheeling volumetric charges and renewable energy surcharges apply. ※5 The 30-minute price for the relevant area in the spot market operated and published by the Japan Electric Power Exchange (JEPX). ※6 A purchase handling fee of JPY 1/kWh applies. “My own power generation” for everyone: Peepa does not require contracting an entire power plant. Instead, customers contract only the sections they need. Like choosing seats in a movie theater online, users can select only the required sections. Because Peepa is a monthly subscription service with no initial fee, anyone can use it easily wherever they live. Applications can be completed from the Minna Denryoku member page in as little as two minutes. About Minna Denryoku: Minna Denryoku provides 100% renewable electricity※1 procured from renewable energy power plants across Japan as “electricity with a visible face.” Individual household users can allocate part of their electricity bill, JPY 100, to support power plants or projects. This support cost is covered by Minna Denryoku and does not create any additional burden for users.
