  • A Midwestern Power Company employed the services of Valdes Engineering Company to enhance its start-up feed water pumping system. Their existing arrangement did not provide a back-up should the existing equipment fail, and presented operators from starting or filling more than one boiler simultaneously.

  • A Midwestern utility selected Valdes Engineering Company to prepare an engineering study to evaluate the proposed relocation of the electrical output from eight turbine-generators. Valdes developed applicable alternatives and their associated budget cost estimates, which would allow the utility to assess the technical, operational, logistical and financial implications of the project.
