Battery Replacement Work Statement Golden Gate National Recreational Area NPS

REQUEST FOR QUOTATION (RFQ): 140P8624Q0008

REMOVE, REPLACE, TEST BATTERIES

QUATERMASTER WAREHOUSE OF ALCATRAZ ISLAND, SAN FRANCISCO, CALIFORNIA

SCOPE OF WORK (SOW)

1. Background

Alcatraz Island is primarily powered by a photovoltaic system comprised of 959 318W Sun Power modules, 480 Deka Unigy II Gel Batteries (the batteries are arranged in two UPS strings of 240 batteries each, UPS-A and UPS-B), and 8 Princeton Power 100KW inverters. In addition to the specifically listed equipment, the electrical system also consists of electrical switching and distribution equipment, meters, control panels, transmission lines, transformers, PV module arrays, main service panels to and including the main breakers, electrical safety signage, inverters, electrical fixtures, and control modules.

In 2018, the entire battery count was replaced including 24 spares; a remote monitoring system was also installed under that same contract.

NPS had noticed that while the solar system is floating the batteries (charge applied to the battery to maintain the battery capacity at or near the full charge), the batteries are noticeably out of range from one another. The battery monitoring system, before both strings went down, showed 36 batteries that were showing lower resistance than what the specs state. Without intervention the system has deteriorated to the point it is not functioning.

2. Scope of Task

The battery room is located at the ground floor of the Quartermaster Warehouse.

See Exhibit A – Alcatraz Map.
