CMS Enterprises and Tondu Energy Services
The CMS Enterprises and Tondu Energy Services partnership selected Commonwealth to repower the existing steam turbine and fulfill the process steam needs with the use of combustion turbines and heat recovery boilers at the TES Filer City station. The station has two 300 kpph boilers to generate steam that is conveyed to the steam turbine, where the majority is used to generate power. From the turbine, 50 to 100 kpph is extracted and used by a thermal host for process heating.
Commonwealth assisted the Owner with evaluating the performance of the proposed new plant configuration, development of technical information required for an interconnection application to Midcontinent Independent System Operator, Inc. (MISO), and aiding the Owner in submission of an air permit application. An RFP was prepared to obtain indicative pricing from EPC contractors for complete project installation with performance guarantees. Commonwealth helped the partnership in evaluating the bids and developing terms of the final contract.
Throughout the course of development, Commonwealth also assisted the Owner in developing electrical one-line diagrams, site arrangements, grid interconnection impact studies, and capital cost estimates. Commonwealth is reviewing contract documents including specifications and drawings provided by GE for the combustion turbine and the EPC contractor. Going forward, Commonwealth is poised to offer engineering field assistance during construction as well as technical support in an Owner’s Engineer role.
The Owner is currently pursuing potential contracts for additional power purchase agreements, steam purchase agreements, and long-term service agreements. These contracts will ultimately shape the project goals for the life of the plant.
