Celanese Corporation announced a 15-year contract extension with Calpine Energy Solutions, LLC to incorporate a solar power component into the electricity supply mix for the company’s world-class acetyl intermediates chemical manufacturing facility located in Clear Lake, Texas. Calpine Energy Solutions is expected to supply the Celanese Clear Lake facility with 45 megawatts of peak solar contracted capacity. On an annualized basis, this represents approximately 142,000 megawatt hours of renewable energy and will equate to taking approximately 14,500 cars off the road. This contract equates to about 33 percent of Celanese’s annual electricity consumption at the site and approximately 65% of the site’s daytime electricity usage during the summer months. As the site owner, Celanese will extend this solar power supply to other site partners at the Clear Lake facility. Site partner Arkema, which owns and operates the acrylic acid and acrylic esters units at the Clear Lake site, has expressed a strong interest in solar power supply.
