Japanese operator At Tokyo Corporation (aka @ Tokyo) has signed a Power Purchase Agreement (PPA) to offtake from a solar farm in Japan.

The company this week announced a “basic agreement on a virtual PPA” with Mizuho Leasing and its subsidiary ML Power.

This initiative involves converting a 28MW solar power plant, invested in by a consolidated subsidiary of Mizuho Leasing and operated under the Feed-In Tariff (FIT) system, to the Feed-In Premium (FIP) system and then supplying At Tokyo with non-FIT non-fossil fuel certificates.

The FIT system sees power companies purchase electricity generated from renewable energy sources at a fixed price set by the government for a certain period. The FIP system sees a premium added to the price, based on the difference between a predetermined standard price and the market price.

Founded in 2000, At Tokyo offers services from 13 data centers across Japan; five in Tokyo and three in Osaka, and each in Hokkaido, Kagawa, Okinawa, Hiroshima, and Fukuoka.

One of the largest in the world, the Chuo Center (CC1) facility in Tokyo spans more than 140,000 sqm and offers 70MW of capacity, while the Tokyo Data Center #2 (DC2) is an underground facility.

At Tokyo’s investors include Tokyo Electric Power (Tepco), Japanese security company Secom, and IT consultancy Intec.
