Norwegian solar energy company, NorSun, has selected Tulsa, Oklahoma for its first U.S.-based factory, an initial planned investment of $620 million in a new 5 GW silicon ingot and solar wafer manufacturing facility. The expansion, which was facilitated by the Oklahoma Department of Commerce and Tulsa Airports Improvement Trust, will create 320 new direct jobs and provide critically needed domestic production of ingot and wafer capacity to meet the increasing demand from U.S. solar cell and panel manufacturers, supporting the growth of the renewable energy sector.
“Our business plan has an ambitious timeline, so we knew we needed a partner who can work fast and efficiently to meet the critical need for American-made energy,” said NorSun CEO Erik Løkke-Øwre. “Oklahoma impressed us even before our selection journey – its robust clean energy, manufacturing ecosystem and workforce development programs were already on our radar, and its competitive business offerings and site acceleration options solidified our decision.”
NorSun has identified a greenfield shovel-ready site of approximately 60 acres. Construction is expected to begin in late 2024, subject to approvals, necessary permits and final incentive agreements.
“I’m thrilled to welcome a new company bringing high-quality, high-paying jobs to our community. Innovation and excellence thrive in Tulsa, and so will NorSun. Thank you to Governor Stitt for working to make Oklahoma the best place to do business!” – U.S. Congressman Kevin Hern (OK-01)
Production is anticipated to come online in 2026, making the Oklahoma facility among the first in the United States to produce high-performing silicon ingots and wafers, currently the biggest bottleneck in achieving a fully domestic solar supply chain. The Tulsa site offers an opportunity to further expand production up to 10 GW as the U.S. continues to prioritize domestic energy manufacturing.
