RFP_PR9169__Addendum_No._4.pdf

This Addendum No. 4 document is issued by the Orlando Utilities Commission (OUC) in Orlando, Florida, in response to RFP PR9169 for a Microgrid Energy Storage Solution System. The RFP solicits proposals from qualified suppliers to design and construct an Energy Storage System (ESS) with a capacity of 250 kW capable of generating power for 1 to 2 hours. The system will be co-located with DC Fast Charging (DCFC) infrastructure for electric vehicles and must meet specific operational requirements outlined in Attachment D of the original solicitation. The revised bid submission deadline has been extended to Friday, July 24, 2026, at 2:00 p.m. EST, with proposals to be submitted via Vendorlink to OUC's Strategic Sourcing Department at 100 W. Anderson Street, Orlando, FL 32801. All prospective proposers must acknowledge receipt of Addenda Nos. 1, 2, 3, and 4 in their bid responses, or their proposals may be deemed non-responsive.

The ESS is required to operate in grid-connected mode to provide grid services including peak shaving, solar smoothing, and Volt/VAR regulation, and must be capable of exporting power to the grid in response to utility signals. During outages, the system must function as a grid-forming microgrid to maintain support for DCFC operations. While suppliers are required to clearly indicate compliance or non-compliance with requirements in Attachment D, non-compliance does not automatically disqualify proposals; OUC will evaluate submissions to determine the best solution for its operational needs. Direct communication between suppliers, their employees, or subcontractors with OUC personnel is restricted to the designated buyer of record, Bhumika Nathoo, to ensure procurement integrity.
