Substation Construction Services

The Grand River Dam Authority requires a vendor to provide substation construction services in Pryor, Oklahoma. The requested scope includes expanding substations and switching stations, installing terminal additions, completing transmission line cut-ins and terminations, installing transmission structures, and replacing or setting equipment like breakers, switches, and structural steel. The contractor must also execute foundation civil work, grounding system modifications, conduit and cable work, control building modifications, civil site work, and construction support for testing, commissioning, energization, and turnover documentation. Only onshore USA vendors are eligible to bid, and the performance of the work will take place onsite. Interested bidders must attend an in-person pre-bid meeting on October 15, 2026, and submit all questions by October 19, 2026. Vendors may submit their responses digitally via email or online, though the text does not specify the final submission deadline or evaluation criteria. The selected contractor will fulfill a contract term of one year, and the buyer is currently looking for proposal pricing rather than providing a set budget.
