The deal, which effective from January 2016, is a part of Apple’s effort use 100% renewable energy to power its facilities located across the globe.

Under the terms of the agreement, Sunseap will supply 40 gigawatt-hours (GWh) of power generated from its rooftop solar energy systems which are installed across more than 800 buildings in Singapore, to Apple.

Sunseap Group director Lawrence Wu said: "Sunseap’s blended offer of solar leasing and clean energy retail addresses the issue of limited roof space."

In particular, the power purchase agreement allows Apple to meet its electricity needs in the country, including 2,500-person corporate campus and new retail store in the region.

Apple environment, policy and social initiatives vice-president Lisa Jackson said: "Climate change is one of the great challenges of our time, and it’s going to take determination and innovation to make the much needed transition to a green economy."

Sunseap said that Apple is the firm to be 100% powered by renewable energy in Singapore.

Singapore Economic Development Board (EDB) Cleantech executive director Goh Chee Kiong said: "Sunseap’s strategic partnership with Apple represents a new frontier in Singapore’s drive to utilize more cost-competitive renewable energy, and at the same time, achieve environmental sustainability and energy security."

"We are confident that this pioneering business model of offsite power-purchase agreements will help Singapore address our space scarcity challenge and spur even more companies in Singapore to scale their renewable energy usage."

Additionally, Sunseap is working with various government agencies and energy service companies in order to provide new clean energy product offerings, thus allowing clients to achieve sustainability goals.

In October, Apple proposed its plan to build 2GW of clean energy projects in China.
