Prisma Energy International, based in Houston, Texas, was formed in 2003 as a former subsidiary of Enron Corporation. Its core mission is to manage and operate major overseas assets, previously under Enron International. The company focuses on the mining sector and employs over 6,600 people globally. Prisma Energy was initially conceived during Enron's bankruptcy reorganization plan and was referred to internally as "InternationalCo" before its official establishment.

Prisma Energy International has made significant strides in managing and optimizing Enron's former international assets. The company's global workforce and strategic management have enabled it to maintain a strong presence in the mining industry. Its formation marked a pivotal step in the reorganization of Enron's extensive overseas operations, ensuring continuity and stability in the management of these critical assets.
