Stonepeak Infrastructure Partners, a New York-based private equity firm, has reportedly appointed Australia’s Macquarie Capital as financial advisor for a possible sales process of its stake in the 50 MGD (189,250 m3/d) Carlsbad Seawater Desalination Plant. Poseidon Resources partnered with Stonepeak to form Orion Water Partners, the joint venture that built, owns and operates the Carlsbad plant. The project required $922 million in financing, $734 million of which was arranged through the sale of tax exempt bonds issued by the California Pollution Control Financing Authority on behalf of Poseidon and the San Diego County Water Authority.
