Cubic Corporation Saves Estimated $3 Million Lifetime With Integrated Cleantech System

Cubic Corporation, a technology-driven leader in transportation and defense solutions, has taken a major step toward sustainability at its Kearny Mesa headquarters in San Diego. Guided by a strong commitment to corporate social responsibility, Cubic continually seeks new ways to integrate sustainability into its business practices. Through forward-thinking initiatives and environmentally responsible development, the corporation aims to reduce greenhouse gas emissions and set a standard for sustainable operations across its industry.

The Challenge

Implementing Clean Energy Without Upfront Capital

As Cubic Corporation prepared to redevelop its Kearny Mesa headquarters and consolidate more than 1,000 employees onto a single campus, the company sought to significantly reduce its environmental impact and operating costs. However, implementing a comprehensive clean energy solution — combining solar, battery storage, and electric vehicle charging — posed financial and logistical challenges. Cubic needed a way to integrate these advanced technologies to support its sustainability mission and LEED building goals, all without committing upfront capital or taking on performance risk.

INCENTIVES

Self-Generation Incentive Program (SGIP)

To help Cubic Corporation achieve its sustainability and operational goals, PowerFlex designed, built, owns, and operates an integrated energy system at the Kearny Mesa campus with zero upfront costs to Cubic. The system features a 962-kilowatt (kW) carport solar array, 280-kW / 540 kilowatt-hour (kWh) battery energy storage, and 121 smart EV charging stations, all tailored to the facility’s unique energy needs. PowerFlex’s Adaptive Load Management® technology optimizes EV charging to align with solar production and building load, eliminating the need for costly utility upgrades. By leveraging a power purchase agreement and lease business model, Cubic benefits from immediate energy savings, reduced demand charges, and a significant reduction in greenhouse gas emissions — all while supporting the company’s LEED building initiatives and sustainability mission.

Maximizing Financial and Environmental Benefits

By generating and storing solar energy on site, Cubic Corporation is able to lower overall utility consumption and shift energy usage to avoid costly demand charges. The integrated system is projected to save Cubic $93,000 annually and $3 million over its lifetime, all without any upfront capital investment or performance risk. In addition to financial savings, the project supports Cubic’s broader sustainability mission by providing employees with access to clean energy through EV charging and complementing other energy efficiency measures, such as high-efficiency lighting and advanced building systems, incorporated into the new LEED Silver-certified campus.
