01. OBJECTIVES AND DESCRIPTION OF PROJECT

JEA is seeking an experienced and qualified design and construction team to perform all engineering, permitting, design, structure/material procurement, and construction services required to build a new 230/26kV substation at the southwest corner of the intersection of Normandy Blvd and New World Rd, in Jacksonville FL, 32221. See Figure 1.

Figure 1: Substation Site

01.01 Background

JEA has secured a transmission corridor to extend an existing 230kV transmission circuit to serve existing and new customers in the area. A distribution substation, to be named New World Substation, will be built on the south side of Normandy Blvd to serve the needs in the area. The substation has a proposed in-service date of

November, 2028.

01.02 Project Description

This substation will be provisioned for three (3) power transformers, nine (9) distribution feeders, and three (3) cap banks. There is an additional provision within the substation for either one (1) additional power transformer, or a transmission line. Initially, two (2) power transformers, six (6) distribution feeders, one (1) CapSwitcher, and one (1) cap bank will be installed, while the remaining 3rd power transformer will be installed at a future, undetermined date.

The high-side of the substation will be of a breaker-and-a-half scheme, with a voltage of 230kV, as shown in

Figure 2.

Figure 2: 230kV Portion of Substation

The low-side of the substation will consist of a 26kV bus system to accommodate three (3) power transformers, with nine (4) 1200 amp feeder breakers, and one (1) 5.4MVAR capacitor bank associated to each transformer, as shown in Figure 3. The three (3) transformer will be interconnected with the use of two (2) main bus tie breakers. This project will install (9) 1200 amp feeder breakers, and one (1) 5.4MVAR capacitor bank, with provisions made for a T2 capacitor bank, to be installed at a future undetermined date.

Figure 3: 26kV Portion of Substation

Figure 4 is a depiction of the initial, geographically referenced, breaker-and-a-half scheme substation layout.

The layout establishes a transmission corridor, fence, roadway, and areas for retention pond(s).

Figure 4: Initial Substation Layout

At the commencement of construction, the Proposer shall clear the substation parcel, except for the first 135’ on the north side of the substation parcel, which will be cleared by the supporting scope coordinated by JEA

Transmission Projects group. See Figure 5. This transmission project will clear their portion of the parcel in advance of this project to establish a transmission corridor.

Figure 5: Boundary for site Clearing. Area is green to be cleared by another

The JEA Transmission Projects group will install two (2) poles directly north of the two eastmost 230kV substation bays. During construction, the Proposer shall coordinate with the JEA transmission group, and inform the transmission group on when the substation project is ready to attach the transmission conductors and shield wire from the #1 and #2 transmission poles to the two (2) substation A-frames. See figure 6.

Figure 6: Transmission Coordination

Prior to the commencement of site clearing and construction of the substation, the JEA Distribution Projects group will remove the existing distribution line, located in the center of the substation parcel. See figure 7.

Figure 7: Existing Distribution OH Line

02. SCOPE OF SERVICES

JEA intends to award one (1) contract to the most highly qualified team that meets the minimum qualifications to submit a proposal and with which JEA can successfully negotiate a contract. The project delivery method will be a progressive design build (PDB), with the goal of substantially completing (energizing substation) the project in its entirety by November 22nd, 2028. During design and construction, JEA intends to hold weekly, Bi-weekly, and/or monthly meetings, as required, with the winning Proposer maintaining the project schedule throughout. The Proposer shall initially correspond with a single JEA point of contact (POC). Additional JEA

POC may be identified as the project progresses.

The Proposer shall provide the guaranteed maximum price (GMP) no later than the 60 % design checkpoint.

The GMP will include procurement and construction.

Major items that shall be procured by JEA, include the two (2) T1 and T2 power transformers, one (1)

CapSwitcher, eight (8) 230kV SF-6 breakers, and nine (9) 26kV vacuum breakers. The Proposer is responsible for the transportation of all eight (8) 230kV SF-6 breakers (JEA Maintenance shall be responsible for verifying correct level of SF-6 gas in each breaker), and all nine (9) 26kV vacuum breakers to site from JEA’s

Commonwealth Service Center. JEA shall be responsible for transportation of the T1 and T2 power transformers to site, performing all lifts, including onto the concrete pad, assembly, and testing of the power transformers. At the commencement of construction, the T1 and T2 power transformers, along with the 230kV and 26kV breakers shall be stored at an existing substation nearby TBD.

A list of materials to be furnished by JEA through their storeroom shall be provided in Appendix A of the bid documents. Early in the project, the Proposer shall be responsible for identifying storeroom supplied material not provided by the Proposer, and inform the JEA POC of the need to order the pertinent material through the storeroom within enough time to meet the project schedule. The Proposer shall transport all storeroom supplied material to site.

All other materials required to construct the substation shall be procured by the Proposer. All labor, construction materials, and equipment needed to complete construction shall be supplied by the Proposer.

JEA shall perform all services required for testing and commissioning of the substation. JEA shall also perform all engineering related to protection and control, along with procurement of the relay panels.

During all phases of construction and inspection, work hours on site shall be as directed by any permits and the

JEA project representative. Typical workdays shall be from Monday to Friday 7:00 am to 5:00 pm.
