Sempra U.S. Gas & Power sold one 625-MW block of its 1,250-MW Mesquite gas-fired power plant to Salt River Project (SRP) for $371 million. In addition to 100-percent ownership of the 625-MW power block, SRP gained a 50-percent undivided interest in plant facilities. Sempra retains ownership of the power plant’s remaining 625-MW power block and 50-percent interest in the plant facilities. As part of the transaction, Salt River Project will become the operator of the Mesquite facility.
