SB Energy, the offshoot of telecoms group Softbank, and conglomerate Mitsui are close to flipping the switch on a 111MW PV array in northern Japan.
The companies said in a statement yesterday that the plant on Hokkaido island would be activated next week, on 1 December.
The joint project was first announced in March 2013 and had initially been scheduled for launch earlier this year.
Built on 166ha of land near the town of Abira, the project is expected to provide power to around 30,000 households, according to the two companies.
Mitsui and SB Energy are collaborating on a number of other utility PV projects in Japan.
