Solution
Under the multiyear contract, our team executed an extensive array of studies, assessments, concepts and projects throughout the port to advance the District’s mission. As each study request arose or grew into executable projects, our team provided holistic services to assist at every stage. A selection of the most prominent requests included:
Tenth Avenue Marine Terminal Microgrid
Our team was tasked with the preparation and evaluation of a detailed feasibility study for an on-site solar and battery storage microgrid. We conducted solar assessments, electrical load analysis, electrical interconnection evaluation, battery energy storage modeling, economic modeling and more to provide viable plan recommendations.
Based on our evaluation, we recommended a permanent, renewable microgrid at the Tenth Avenue Marine Terminal, incorporating solar photovoltaic generation, battery energy storage, energy efficiency improvements and a centralized microgrid controller to sustain operations when islanded from the electrical grid. Collaborating with the District, we prepared a winning grant application for $5M grant awarded to help fund microgrid. We are now providing engineering design, procurement, construction support and owner’s representative project management services for the project.
B Street Pier Mobility Hub Feasibility Assessment
Looking to expand its existing 20-megawatt (MW) Cochran Marine Shore Power system capacity at the B Street Pier, the Port requested a technical and financial feasibility analysis. This analysis determined the viability of providing shore power to two cruise ships simultaneously while also developing a power distribution system for electric vehicle (EV) charging stations for public passenger vehicles and charter bus companies. We identified ideal locations for new EV charging stations and electrical infrastructure, while also helping the District evaluate engineering and construction scope and costs required to implement the upgrades.
National Distribution Center Fleet Electrification Study
To support heavy-duty and passenger vehicle electrification at the National Distribution Center, we conducted a thorough evaluation of electric load growth, distributed generation and infrastructure upgrades. The study looked at the potential for deploying charging infrastructure, refrigerated container outlets, rooftop solar and battery storage to develop a model for zero-emission goods movement. We also developed site layout diagrams, electrical single-line diagrams and preliminary construction cost estimates in support of the District’s due diligence analysis and pursuit of project funding.
Building Energy Management
We conducted an evaluation and recommended an approach to upgrade the District’s Building Automation Systems (BAS) that manage and control the building systems of multiple facilities. The study involved inspecting existing equipment to be controlled and monitored by a new BAS and evaluation of the equipment relative to typical useful life expectancies; reviewing five of the top available BAS products in the market from operational and cybersecurity perspectives; and developing a phased approach for implementing the BAS upgrades. Key considerations included capital costs of system and equipment upgrades, potential for leveraging existing systems and equipment, and cost savings opportunities from long-term energy management and increased staff resource efficiency.
