SCOPE OF WORK

This Statement of Work describes the specifications for the procurement and installation of 3 phase 480V, 800A double throw disconnect switch and switchgear trip elements for the J Strom Thurmond Lake Office station service feed and installation of a government furnished 3 phase 480V, 500KVA Emergency Diesel Generator.

1.0 GENERAL

J Strom Thurmond with the Us Army Corps of Engineers is a hydroelectric power plant that operates with seven (7) 54 MW generators on the Savannah River in Clarks Hill, SC. The project has recently undergone a 480 V Motor Control Center and Station Service Switchgear upgrade to Eaton branded equipment. The project provides the station service feed to the Project Manager’s Office. There is one feed from the Station Service Switchgear Bus 2 to provide power to the Project Manager’s Office and it is necessary to install another feed from Station Service Switchgear Bus 1. The project has a 480 V Emergency Diesel Generator on site that has never been operated, installed, or commissioned. It is necessary to install the Diesel Generator and terminate to the pre-designated breaker in Station Service Switchgear 2.

2.0 SCOPE

2.1 480 V PMO Feeder Installation

The station service setup at J Strom Thurmond is an Eaton Magnum DS three phase 480V double bus setup. The two busses are tied together via a tie breaker. The existing setup for the

Project Manager’s Office (PMO) station feed is a single feed from Bus 2. See drawings in Appendix A of current switchgear setup. This request for proposal is for the installation of a new feeder from Station Service bus 1 to feed the PMO office transformer. The 65 FT of 750 KCMIL necessary to complete this task will be provided by the government. The contractor will be responsible for providing the grounding conductor for the feeder. A separate grounding conductor is required. A three phase, three position disconnect switch will need to be purchased and installed by the contractor. The new three position disconnect and enclosure must meet the specifications of section 3.0 Materials. The disconnect switch will have a Bus 1 Feed, Bus 2 Feed, and an off position. A new 400 A digitrip element will need to be purchased for the switchgear 2. The trip element will need to meet the specifications listed under section 3.0 Materials. A spare 400 A breaker in the switchgear will be used to terminate the new PMO feeder. The three position disconnect switch will be installed in the switchgear gallery as shown in the drawings in Appendix A. The existing feed to the PMO will be removed from Station Service bus 2 and relocated to the new disconnect switch. The contractor will install new Government furnished feeder cables from Station Service Switchgear 1 and 2 to the new disconnect switch.

The contractor is required to comply with EM385-1-1 and the onsite Hazard Energy Control Program (HECP) to include a 90 minute onsite training session with quiz. All HECP requirements will be followed when working with electrical clearances. USACE personnel will be responsible for de-energizing the equipment, and the contractor will observe a zero voltage state when working on the equipment. The contractor is required to give at least a week notice for when the equipment will need to be de-energized and work will begin. The contractor will be responsible for installing the new 400 A digitrip in place of the existing 200 A trip in breaker 2b of Bus 1 in the Eaton Magnum DS station service switchgear. The contractor will terminate the new cable in the breaker 2b of Switchgear 1. The contractor will be responsible for running new cable in new RMC conduit that will feed into the existing cable tray. The contractor will pull the cable through the existing conduit and new conduit the contractor sets up to the new disconnect switch on the upstream wall in the switchgear gallery. The contractor will be responsible for installing the new disconnect and terminating the new feeder cable.

2.2 480 V Diesel Generator Installation

The Cummins DFEH-8578821 diesel generator is furnished by the government. The Diesel Generator will be moved by the contractor to its location on the transformer deck. See moving plans submittal in the submittal section. The dimensions of the deck are listed in the drawings of appendix A. The generator is 16,040 lbs dry and will be located on the unloading deck. The power plant staff can assist in lifting the generator on a loading platform on the unloading deck with the power house crane. The project does not have a means to lift or move the generator to the transformer deck location and it will be the contractor’s responsibility to move it to the new location. The required 350 Kcmil cable will be furnished by the government.

The 350 Kcmil cable will be run by the contractor in parallel to achieve the required 600 A rating. The approximate 80 FT of 350 Kcmil needed for this will be supplied by the government.

The contractor will provide the grounding conductor for the parallel feed. A separate grounding conductor per parallel feed is required. It will be necessary to make vertical core drills through 18-24 inches of concrete from the Transformer deck directly below to the Station Service Switchgear. Ground Penetrating Radar (GPR) results must be done on both sides of the surface and be approved by USACE before penetrations begin. The contractor must provide weather sealing on the penetrations on the transformer deck to prevent leakage. Plant raw water and conduit as-built drawings must be reviewed before final drills begin. The contractor will provide the necessary diesel fuel for commissioning and leave a full tank before when the contract is completed. The contractor must commission the generator and have a certified Cummins diesel technician on site during commissioning. The guidelines listed in the diesel generator installation guide must be followed. The contractor will be responsible for mounting the diesel to the deck and placing vibration isolators per the manual. The contractor will make a penetration large enough for two 3 inch 4 inch conduit and two ¾ inch conduit through the deck. The contractor will run the parallel 350 Kcmil conductors from the output of the diesel generator to the switchgear bellow. The conductors will be run in parallel conduits from the switchgear to the diesel generator. The contractor will be responsible for running conduit and terminating on the predesignated 600 A breaker in the switchgear bus 2 position 5C. The contractor will run the remote start for the diesel generator to the remote start output of the station service switchgear.

The remote start control wiring will be run in its own ¾” conduit. The contractor will also run the power for the heaters and battery charger through a ¾” conduit. Power for these terminations can be run from the lighting panel in the switchgear gallery and run through the cable tunnel to the switchgear’s cable tray. Panel PLP2 is a 120/208V panel near the switchgear that will be used to provide power to the Diesel Generator heaters (240V) and battery charger (120V). The battery charger will require a 10A 1pole/single throw breaker and the heaters will require a 30A double pole/double throw breaker installed in panel PLP2. The breakers will be provided by the contractor. The battery charger will also require the installation of a 120V outlet to be installed inside the DG close to the Battery Charger plug for connection. There is a remote annunciation panel included with the diesel generator that will need to be mounted by the contractor bellow the existing power control annunciation panel. Power for remote annunciator will be run from same source as the internal annunciator panel. A battery for the diesel generator will need to be provided by the contractor per the manual.

2.3 Option 1: Program Eaton Switchgear PLC

This option lays out the plans for the contractor to design a program for the existing Eaton PLC in the 480V Station Service Switchgear. The program will be designed by the contractor to act like a transfer switch. When 480 V station feed goes down for more than 10 seconds, the program will shed all loads and start the diesel generator. Critical loads that will be brought in will be MCC U16, Main Unit MCCs (7 MCCs for 7 Units), MCC U12, MCC U10.

These loads will be brought in on bus 2 with the tie breaker open. Permissive will need to be in place to ensure that the main feeder breaker cannot be closed while the diesel generator breaker is closed. There will need logic of the program that will start the generator once a month for 15 minutes to insure the diesel has its prime. When the diesel generator is up to rated voltage the program will sequentially close in essential loads. After power is restored the program will shut off the diesel generator and close back in the plant loads.
