Vinson & Elkins represents Wayzata Investment Partners LLC in MinnTex Power Holdings LLC’s pending sale of a power plant in Guadalupe County to Calpine Corp. for about $625 million.

Houston-based Calpine turned to White & Case.

On Dec. 2, Calpine announced it had agreed to buy the 1,050 megawatt, combined-cycle power plant from MinnTexPower Holdings, a portfolio company owned by a private investment fund managed by the Minnesota-based Wayzata Investment Partners.

The transaction is expected to close during the first quarter of 2014, subject to customary closing conditions, antitrust review under the Hart-Scott-Rodino Act and approval from the Public Utility Commission of Texas.

V&E mergers-and-acquisitions partners Trina Chandler of Houston and Caroline Blitzer Phillips of New York City represent Wayzata, with assistance from finance/M&A associate Ashley Tufts and capital markets/M&A associate Matthew Greenberg, both of Houston.

New York partner Michael Shenberg led White & Case’s team for Calpine.
