A system for providing hydrogen enriched fuel includes first and second gas turbines. The second gas turbine receives a fuel from a fuel supply and portion of compressed working fluid from the first gas turbine and produces a reformed fuel, and a fuel skid provides fluid communication between a turbine in the second gas turbine and a combustor in the first gas turbine. A method for providing hydrogen enriched fuel includes diverting a portion of a first compressed working fluid from a first compressor to a second compressor and providing a second compressed working fluid from the second compressor. Mixing a first portion of a compressed fuel with the second compressed working fluid in a reformer to produce a reformed fuel, flowing a second portion of the compressed fuel to a second turbine for cooling, and flowing the reformed fuel through the second turbine to cool the reformed fuel.
