Demand for Sibelco HPQ – sold under the brand name IOTA®
– continues to increase and is confirmed under long-term sales agreements that include prepayments with customers in the global solar photovoltaic market. Consistent with this market growth, Sibelco has already increased production of HPQ by over 70% from 2019 to 2023 (forecast) through process efficiencies and the initial benefits of the $200 million Expansion 1. In addition, Sibelco has commenced planning towards Expansion 2, a further investment of the order of $500 million to be executed between 2024 and 2027. Expansion 2 is expected to be larger than Expansion 1. These expansions are underpinned by a mine life potential of more than 100 years.
Expansion of installed capacity at Spruce Pine will lead to the creation of valuable new jobs in North Carolina where Sibelco has been operating since the 1970s.
Our investments will ensure that Spruce Pine remains the world’s leading source of HPQ. We are in an excellent position to respond to market demand and ramp up production sustainably thanks to our customers’ appreciation of our high-quality products. We clearly understand that our IOTA® HPQ products play a critical role in the global semi-conductor and solar photovoltaic industries and with Expansion 1 and Expansion 2 we intend to invest an estimated $700 million to provide an unrivalled value proposition to our customers in terms of product quality and availability as well as long-term security of supply.
