Westlake Chemical Partners LP is a limited partnership that owns and operates ethylene production facilities and related infrastructure through its controlling interest in Westlake Chemical OpCo LP. The partnership operates three ethylene production facilities in Louisiana and Kentucky and a 200-mile ethylene pipeline, generating revenue primarily through sales of ethylene and co-products under long-term agreements with its parent company Westlake. The business model is structured to provide stable, predictable cash flows through fixed-margin pricing on ethylene sales that covers feedstock costs, natural gas, operating expenses, maintenance capital, and a guaranteed per-pound margin, with minimal commodity price exposure and minimal third-party customer concentration.
