Upgrade U.S. Coast Guard Crossing Signs - San Diego International Airport Lindbergh Field San Diego, California

Contracted by the San Diego County Regional Airport Authority to design the electrical portion of the Upgrade U.S. Coast Guard Crossing Signs Harbor Drive Project. The project was comprised of upgrading existing message board signs and supports located on N. Harbor Drive. The existing power to the signs was disconnected and a new point of connection (POC) established. Design of the new signs required approval and coordination with the San Diego Regional Airport Authority. Obtaining of permits and plan check approval by the City was also overseen by LEI.

Houweling Nurseries Camarillo, California

LEI was retained by ViaSol to design a Single-Axis Tracking Photovoltaic system for Howeling Nurseries in Camarillo, California. This “1MW PV Solar Array – Howeling Nurseries” project provides renewable power generation at the facility. It reduces current energy usage primarily during daily peak periods, which is the most expensive energy to generate. A steel structure was erected above an irrigation pond to provide the module mounting area. The combiner boxes and pumps were also mounted on the raised structure. The inverters, transformer and electrical panel boards were mounted on a raised concrete structure near the south end of the pond. System design utilizes five thousand four hundred and eighteen (5418) photovoltaic modules, each rated for 210 watts at full power. To combine and convert the power from the photovoltaic modules, thirty three (33) combiner boxes and four (4) 250kW inverters were designed. Each inverter feeds an electrical switchboard’s fused disconnect. This, in turn, feeds back to the main switchgear via a metered utility visible disconnect with disconnects on both sides of the meter. The single-axis tracking system is fed by the photovoltaic array through an uninterruptible power supply.
