GreenRock Energy Leads Taiwan's First Agri-PV Grid Connection in Japan
GreenRock Energy's agricultural photovoltaic project in Japan has successfully connected to the grid and secured backing from Japanese banks.
Taiwan's renewable energy industry has reached a new milestone as GreenRock Energy successfully expands into Japan’s agrivoltaics market. The company’s Kurihara Plateau Power Plant in Miyagi Prefecture was recently successfully connected to the grid, with an installed capacity of 2MW. The project benefits from a highly competitive feed-in tariff of up to JPY 36 per kWh, ensuring long-term and stable revenue. With this achievement, GreenRock Energy has become the first Taiwanese company to enter Japan’s agrivoltaics renewable energy sector and achieve successful grid connection.
Agrivoltaic projects require a careful balance between agricultural productivity and power generation to achieve mutual benefits. In this project, GreenRock Energy partnered with local farmers in Miyagi Prefecture who operate a self-produced, self-sold forage cultivation model. This approach maintains over 80% of agricultural output, in compliance with Japan’s Agricultural Land Act. The project received certification from Japan’s Ministry of Economy, Trade and Industry (METI) and the Miyagi Prefectural Government, along with strong financial backing from Japanese banks—demonstrating a high level of trust from both government authorities and financial institutions in GreenRock Energy.
Founded in 2019, GreenRock Energy has a paid-in capital of NTD 410 million and plans to apply for listing on Taiwan’s Emerging Stock Market (TPEx) next year. Chairman Meng-Heng Yeh, who holds a Ph.D. in Materials Science and Engineering from National Cheng Kung University, brings extensive experience in renewable energy development and has led the team in actively expanding into overseas markets.
GreenRock Energy continues to report positive progress. In addition to its success in Japan’s agrivoltaics sector, becoming Taiwan’s first company to achieve grid connection in this field, the Group’s ground-mounted solar project in Fukushima, Japan, is scheduled to complete grid connection and commence commercial operation on November 30. With an installed capacity of 1.44MW, the project is expected to generate approximately 1.51 million kWh of electricity annually, supplying power to around 378 Japanese households and reducing approximately 756 metric tons of CO₂ emissions each year.
In recent years, GreenRock Energy has actively expanded its global footprint and strengthened its international energy portfolio. The company has established a Japanese subsidiary, GreenRock Japan, to deepen its presence in the local market. Vice President Yi-Da Tsai expressed strong confidence in Japan’s energy market and plans to position Japan as 30%–40% of GreenRock Energy’s global portfolio. Currently, GreenRock has 50MW of solar projects under development in Japan, along with 100MW of energy storage system capacity.
Regarding its strategic roadmap in Japan, Tsai emphasized that GreenRock Energy will focus primarily on Japan’s capacity market, complemented by participation in the Japan Electric Power Exchange (JEPX). Through localized operations and innovative energy solutions, GreenRock aims to play a meaningful role in Japan’s decarbonization efforts and energy transition, while strengthening confidence among its global customers and partners.
Japan's “decarbonization” policy—commonly referred to in Chinese as “carbon reduction”—places renewable energy at the core of achieving low-carbon electricity. To meet its goal of a carbon-neutral society by 2050, with an interim target for 2030, the Japanese government has identified power sector decarbonization as a critical priority. In 2023, Japan launched the Decarbonized Power Source Development Action Plan, which includes capacity market tenders for power generation units and energy storage systems. This initiative has attracted strong interest and participation from Taiwanese energy companies.
