Start of Operations at the "Nasu Campus Solar Power Plants"

Update:July 14, 2015

With the completion of the construction of the Nasu Campus solar power plants on a portion of our university's Nasu Campus (Nasu-machi, Nasu-gun, Tochigi Prefecture), the facility began supplying electricity to Tokyo Electric Power Company on Tuesday, June 30 and a commemorative ceremony was held on Friday, July 10 to mark the start of operations.

As a liberal arts university based on Christian principles, ICU established the "ICU Environmental Mission Statement" and has worked to take proper care of and adequately manage the environment on campus throughout all of its activities. Given this and the increasing demand in Japan to use renewable energy proactively after the Great East Japan Earthquake, the Nasu Campus solar power plants were constructed using 36,400 m2, or 4%, of the university's Nasu Campus grounds (approx. 970,000 m2).

The solar power plants are comprised of Power Plant 1 (Area: 28,100 m2, Generating capacity: approx. 1.84 MW) and Power Plant 2 (Area: 8,300 m2, Generating capacity: approx. 0.52 MW). About 10,000 solar panels in total are expected to generate approximately 2.4 million kWh of electric energy annually, equivalent to the energy used by approximately 700 ordinary households per year. The electric energy that is generated will be supplied to Tokyo Electric Power Company and profits from the project will be used for the purpose of supporting students, such as for scholarships.

The university considers the start of the Solar Power Generation Project as an opportunity to inform ICU students and many others of the current state and future possibilities of renewable energies. Going forward, the faculty and staff, along with students, will study the role of universities in society and better uses of energy in the university's facilities.


The commemorative ceremony was held in fine weather, with approximately 30 people related to the university and institutions/groups involved with the plants' construction in attendance. Kakutaro Kitashiro, Chair of the Board of Trustees, stated in his address: "With the start of the solar power plants' operations expected to reduce CO2 by approximately 190 times more than an abandoned mixed forest, we will be able to contribute to protecting the earth through the environment. Furthermore, the profits from supplying the generated power to Tokyo Electric Power Company will be used for the purpose of supporting our university's students, such as enhancing scholarships. We will operate the power plants for the next 20 years, which is a long period of time. We are grateful for the cooperation extended to us by the local residents, the people who will manage and operate the facility and those who financed the project. We kindly ask for your continued support."
