Grossmont Union High School District and ENGIE Impact Complete Fleet Electrification Project

School district creates strategic roadmap to transition towards a zero emissions bus fleet and secures corresponding funding

NEW YORK–(BUSINESS WIRE)–#EVENGIE Impact, an ENGIE entity that delivers sustainability solutions and services to corporations, cities and governments across the globe, today announced the completion of a major milestone in its work with Grossmont Union High School District (GUHSD) in El Cajon, CA. GUHSD selected ENGIE Impact to perform two essential tasks, the first being to develop a detailed roadmap for the electrification of the GUHSD bus fleet and the second being to identify and support the school district with the application for grants that would help the school district cover the cost of fleet electrification.

GUHSD’s fleet electrification roadmap supported the development of a plan to fully transition the district’s 67 diesel-fueled school buses to a clean, affordable, and resilient electric fleet over the next 20 years. This shift to zero emission vehicles will reduce greenhouse gas emissions in the communities GUHSD serves, improving overall air quality and eliminating students’ exposure to harmful pollutants. The study determined the ideal charging behavior and the optimal mix of energy supply from the grid and onsite distributed generation to minimize total cost of ownership and maximize GHG emissions reduction.

Electrifying school buses is a key step for the transition to zero-emission transportation,” said Diego Ibarra, the Managing Director, Sustainable Solutions – Americas at ENGIE Impact. “Accelerating fleet decarbonization across our client portfolio is a core offering within ENGIE Impact’s mission. GUHSD is a great example of how fleets – public and private – can develop actionable strategies and detailed plans that ensure a smooth and reliable transition to electric vehicles.”

In addition to fleet electrification, ENGIE Impact helped GUHSD secure funding by identifying and developing responses to federal and state grant solicitations that support fleet electrification efforts. Among those is a grant from the California Energy Commission to support the development of the fleet electrification roadmap.

As a public school district with multiple competing priorities, GUHSD has limited resources to devote to fleet electrification,” said Lindsey Danner, Energy Manager at GUHSD. “ENGIE assisted GUHSD in securing 8 of our 17 new electric buses through a grant from the San Diego County Air Pollution Control District and additional funding to develop our comprehensive plan for fleet electrification. These accomplishments work toward our overall goal to support our community’s educational and environmental needs.”

Based on an initial ENGIE Impact analysis, the electrification of GUHSD’s school bus fleet will reduce total greenhouse gas emissions by an estimated 86%. Looking ahead, ENGIE Impact and GUHSD will explore the expansion of school bus routes especially within disadvantaged communities, the integration of vehicle-to-grid (V2G) capabilities, as well as some workforce development opportunities and challenges for the district’s fleet.
