About this file
This file consists of electrical design and site plan documents for a solar and energy storage installation project at the Pasadena Public Library Central Library, prepared by Stantec for the City of Pasadena Department of Water and Power. The project involves the design and installation of a 276.66 kW DC solar photovoltaic system comprised of 530W Silfab modules distributed across multiple canopy structures with four inverters ranging from 25 kW to 70 kW capacity. The design includes an energy storage system with a minimum capacity of 250 kW and 4-hour duration, four 50 kW DC fast chargers, and ten 12.5 kW Level 2 EV chargers. The solar canopies must maintain a minimum height of 14 feet 6 inches, include lighting compliant with Illuminating Engineering Society standards for parking lots, and preserve existing parking spaces and ADA-compliant pathways. The contractor is responsible for on-site field surveys, design optimization, equipment procurement, installation, interconnection with the City of Pasadena Water and Power electrical system, and commissioning of all systems capable of automatic microgrid operation and backup power provision during outages.
The electrical infrastructure requires the contractor to procure and install a transformer pad, primary and secondary conduits on private property, a 5000-ampere main switchgear with motorized breaker and microgrid controls, an 800-ampere solar switchboard, an 800-ampere EV switchboard, and an 800-ampere battery energy storage system switchboard, all protected by concrete masonry unit walls where applicable. The City of Pasadena Water and Power will provide transformers within the underground vault, high-voltage cables, and service entrance conductors to the main switchgear. All equipment, iron, steel, and manufactured products must comply with Federal Buy America (BABA) requirements with manufacturers providing compliance certificates. The contractor bears full responsibility for repairing or replacing any existing property or utilities damaged during construction and must ensure all electrical service installations comply with City of Pasadena Water and Power Department Electrical Service Requirements (Regulation 21), with preliminary service equipment information requiring PWP approval prior to final design implementation.
