The $134.7 billion Washington State Investment Board has approved an investment of up to $200 million to Prostar Energy Infrastructure Fund II, managed by Prostar Capital.
The closed-end fund invests in assets located in major trading and logistic hubs including the United States, Europe, the Middle East, and Asia.
Its parent firm invests in global midstream energy infrastructure assets that it believes are strategically positioned to serve growing global energy demand.
The WSIB has made three prior commitments to Prostar funds beginning in 2014, spokeswoman Tish Day confirmed in an email.
