60MW Generation Facility RFP_doc.pdf

60MW R.I.C.E. Generation Facility

October 28th, 2025

Request for Proposal:

Dalton Utilities is seeking engineering and architectural services to design a new power generation facility. The new facility will be designed and constructed to support full generation capacity of 6x20MW generators, whereas the initial capacity will be 3x20MW generators. The generators will be paralleled within an arc-resistant metal-clad switchgear lineup which will interconnect with a new substation for exporting. The new substation for export will be designed and constructed by Dalton Utilities, the prime engineer will coordinate the substation grading and drainage within the site development plans.

General Scope of Work:

The successful prime engineer will be required to:

1. Provide a Building Information Model (BIM) in industry standard format, for all systems being installed within the facility. This should include all electrical systems (to include conduits 0.75” and larger), piping, ductwork, and other systems required to be installed within the new building. The Model should be configured in a secure Autodesk Construction Cloud format for review during the design process by the Owner and/or Owner’s Representatives.

2. The project team should anticipate both remote and onsite team meetings for coordination purposes with Dalton Utilities.

3. Provide drawing packages, 30%, 60%, 90%, along with Technical Specifications.

Provide industry standard models, and files at each deliverable for Owner and/or

Owners Representatives review. In addition, providing Rough Orders of

Magnitude (ROM) cost breakdowns at all milestones as indicated.

4. Conduct all coordination with equipment manufacturer(s) for the specification of materials procured by the installing contractor, the Owner, or Others. Provide a matrix of equipment procurement and installation responsibilities during the design process for construction bidders.

5. Conduct all coordination for utility interconnections such as substation, ancillary power, sanitary sewer, water, natural gas, and pipeline requirements.

6. Design storage tanks for diesel fuel backup and assist with all required permitting for associated fuel supply.

7. Ensure the design meets all Local, State, and Federal regulatory and environmental requirements.

8. Provide all permitting assistance.

9. Conduct all Factory Acceptance Testing (FAT) for paralleling switchgear, PLC, Generators, and Ancillary Systems required by the Owner.

10. Provide all testing and commissioning services during construction.

11. Provide project engineering construction support services.

Site Selection and Location:

Looper Bridge Road

Land Lot 14, 13th District, 3rd Section

Whitfield County, Georgia

Plant Configuration

The design team will be required to coordinate all infrastructure requirements for an initial (3) 20MW units with (3) 20MW future units within the facility. This should include building sizing, along with the infrastructure to support the future mechanical systems, electrical systems, controls, SCADA, fire protection, HVAC, and pipeline interconnections.

The site will be developed to accommodate a substation for transmission interconnect and building with parking sized for full capacity of the generation plant. This would include survey, coordination of all grading, storm drainage, sanitary, water, backup diesel storage, ancillary electrical, and ancillary natural gas. In addition, this would include coordination of all underground duct banks for full capacity of the generation plant to a substation located onsite, and pipeline interconnection.

Conduct all Geotechnical Engineering studies for structural designs.
