Hanwha SolarOne Expands Its Presence in China

Hanwha SolarOne Co., Ltd. (the “Company”, or “Hanwha SolarOne”) (Nasdaq: HSOL), a top-10 global photovoltaic manufacturer of high-quality, cost-competitive solar modules is expanding its stance in China, establishing an MOU and supply contracts with 3 acknowledged companies.

On December 4, 2013, Hanwha SolarOne announced that it has signed a memorandum of understanding (“MOU”) with Jiangsu Zhongtian Technology Co., Ltd (“ZTT”) stating their intention to establish a long-term strategic partnership to cooperate in the PV downstream business. The two companies aim to cooperate in the development, construction, financing and grid-connection of PV projects. ZTT intends to use PV modules manufactured by Hanwha SolarOne in its permitted 150 MW distributed energy project in Nantong, Jiangsu Province, China. The two companies intend to enter into a definitive strategic cooperation agreement within 90 days following signing of this MOU.

On December 10, 2013, Hanwha SolarOne announced it has supplied modules for two projects with an aggregate capacity of 50 MW to one of China’s largest state-owned power companies, China Huaneng Group. The modules were delivered to two separate utility-scale installations: (i) an approximately 30 MW in Qingtongxia, a city in the Ningxia Hui Autonomous Region (NHAR) and (ii) a 20 MW project in Wuchuan, Inner Mongolia Autonomous Region.

On December 11, 2013, Hanwha SolarOne signed a contract with Zhejiang Zhentai New Energy Development Co., Ltd. (a member of the “Chint Group”) to supply modules with capacity of 12.96 MW. The modules are scheduled for delivery in December 2013 and will be installed in a utility-scale project in Yongchang, Gansu Province.

Mr. Jay SEO, Chief Financial Officer of Hanwha SolarOne and head of Hanwha SolarOne’s downstream business commented, “We continue to focus on improving our competitive position in the China market and these new MOU and contracts add to our recent success”. Mr. SEO added “We now have a backlog of over 250 MW in China, have begun development of a strategic partnership with Jiangsu Zhongtian Technology, completed several sizeable module supply contracts, are building an EPC competency, and secured a framework credit line with Bank of Beijing for RMB 3.5 billion (approximately US$574 million) over the next three years, providing us the flexibility to fund future downstream projects (IPP) as they develop, without unnecessarily leveraging the balance sheet near-term.”
