1 The principal objective of ACRP Project 02-76 is “to provide guidance in identify- ing and understanding factors that contribute to the use or non-use of gate electrifica- tion systems (electric preconditioned air and electric ground power systems) and ways that airports and airlines can optimize the use of the systems” (ACRP Project 02-76 Request for Proposal). The objective was achieved through engagement with a range of stakeholders, including airport staff from environmental, operational, maintenance, and finance departments; airline staff; airline pilots; and preconditioned air (PCA) and ground power equipment manufacturers and service providers. The airports inter- viewed and surveyed for this project represent a range of sizes, geographic locations, and climate zones. This report is based on information gathered from stakeholders through in-person focus groups, case study interviews, and online survey instruments, supplemented by the literature review. The research considered the impact of weather and climate on utiliza- tion, as well as common utilization tracking practices, airport and airline policies with regard to utilization, best practices for maintaining system availability, and motivating factors affecting the acquisition of systems. This report was developed for all stakeholders involved in the acquisition, installation, operation, maintenance, and utilization of electric PCA and ground power systems. The contents of the report are organized into six chapters: 1. Introduction—This chapter provides background information and establishes the need for the research project, as well as the research approach. 2. Ground Power and Air Conditioning Systems—This chapter provides an overview of commercial aircraft power needs, gate electrification equipment, and systems. 3. Challenges Affecting Gate Electrification System Utilization—The most common chal- lenges to gate electrification system utilization are described in this chapter, which also includes a description of the Self-Assessment Checklist. The checklist is intended to assist stakeholders in identifying challenges to utilization at their specific locations. 4. Solutions to Address Utilization Challenges—Proposed solutions to address common challenges are described in this chapter. 5. Utilization Tracking Methodology—This chapter describes a basic example of utiliza- tion tracking methodology designed for airports to deploy without significant resource investment. 6. Airport Case Studies—Fifteen case studies from airports across the U.S. (and one in Europe) are included to provide readers with an understanding of various types and configurations of gate electrification systems, ownership and maintenance models, and best practices for ensuring system reliability.

As demand for air travel grows, airport-related emissions are increasing and airports are challenged to reduce associated environmental impacts. In response, expanded regulatory programs and global climate protection initiatives are being developed that require the aviation industry—including U.S. airports—to implement new, clean technologies and to modify operational practices to reduce emissions.

One effective option for reducing the emissions associated with aircraft auxiliary power units (APUs) and diesel-powered gate equipment is to convert to electric PCA and electric ground power systems, collectively referred to as “gate electrification systems.”

The TRB Airport Cooperative Research Program's ACRP Research Report 207: Optimizing the Use of Electric Preconditioned Air (PCA) and Ground Power Systems for Airports provides guidance in identifying and understanding factors that contribute to the use or non-use of gate electrification systems (electric preconditioned air or PCA and electric ground power systems) and ways that airports and airlines can optimize the use of the systems.

This research includes case studies at a variety of types and sizes of airports in different climates; an evaluation of how weather and climate impact utilization; the use and impact of other available ground power and PCA units; consideration of aircraft hardstand operations; and airport and airline practices for optimal equipment utilization.

The work includes additional resources: the ACRP 02-76 Ground Power and PCA Example Utilization Tracking Methodology and the Self-Assessment Checklist.
