SEPTA Completes Sustainability Overhaul in South Philadelphia

Projects Transform Southern Bus Depot into Signature Sustainability Site

July 10, 2019

SEPTA's Sustainability Program achieved a new milestone with the completion of a series of innovative projects at the Southern Bus Depot that have transformed the more than 100-year-old facility into one of the most sustainable in the entire transit industry. The transformation was comprised of three distinct projects representing the breadth of environmental focus that SEPTA has undertaken in its now award-winning Sustainability Program, SEP-TAINABLE.

"SEPTA's approach to sustainability is that what's good for the environment can also be good for the bottom line,” said SEPTA Board Chairman Pasquale T. Deon Sr. "These sustainability projects at the Southern Depot exemplify this approach. They demonstrate that significant progress can be made towards our shared environmental goals in ways that are financially responsible. This is why SEPTA's Sustainability Program is so well regarded, and why it has staying power."

First, a comprehensive energy retrofit of the facility itself has achieved substantial cost savings. High-efficiency LED lighting, advanced controls, HVAC upgrades, and building envelope improvements have reduced utility costs by more than $200,000 per year. The project was implemented by Constellation, a leading energy retailer, under the Pennsylvania Guaranteed Energy Savings Act (GESA), which allows public agencies to partner with private Energy Service Companies (ESCOs) to finance energy-saving capital upgrades at no upfront cost to the agency. The project was also supported with rebates for energy efficiency upgrades by PECO's program funded by Pennsylvania Act 129.

Second, a stormwater retrofit, integrated with the repaving project, will capture and manage more than seven acres of water on-site in a surface-level bioretention basin and two large underground retention basins. The stormwater management system is designed to slowly release water into the sewer system, helping to achieve the City of Philadelphia's objectives to reduce the incidence of "combined sewer overflow" events. The project was undertaken with the financial support of the Philadelphia Water Department, which manages the city's innovative "Green Cities, Clean Waters" stormwater management plan.

Third, SEPTA has begun operating 25 battery-electric buses out of Southern District. The buses will serve Routes 29 and 79, which previously were operated with trackless trolleys and will now return to zero-emission technology with SEPTA's first foray into battery-electric technology. The purchase of the 25 battery-electric buses, manufactured by Proterra, Inc., was funded in part by a $2.6 million Federal Transit Administration (FTA) grant under the "Low or No-Emission Program." Combined with 38 trackless trolleys in North and Northeast Philadelphia, SEPTA now has the largest zero-emission bus fleet on the U.S. East Coast. In addition, this project bolsters SEPTA's efforts to generate non-fare box revenues, as a multi-year advertising agreement was reached with PECO to sponsor the new battery-electric bus fleet.

Combined, these projects represent a continued commitment to an industry-leading Sustainability Program. "During my tenure, I have watched SEPTA grow in its approach to sustainability, from one-off projects to comprehensive, collaborative solutions," said SEPTA General Manager Jeffrey D. Knueppel. "Southern District represents the best of these efforts all in the same location. For this reason, Southern District is now among the most sustainable facilities in the entire transit industry."

Each of the sustainability projects at Southern were undertaken with an eye towards financial responsibility. Funding from the Philadelphia Water Department for stormwater management, from PECO for energy efficiency, and from the FTA for the battery-electric buses helped to ensure that the overall program adhered to SEPTA's "budget-neutral" approach to sustainability."

"PECO is very proud of the commitment that SEPTA has made to pioneering environmental efforts with these projects, and we're proud to partner with them to help them achieve their sustainability goals," said Mike Innocenzo, PECO president and CEO. "Electrification, energy efficiency and access to renewable energy is helping our residential and commercial customers save energy and money, and helping PECO contribute to a more sustainable future."

"SEPTA continues to be a leader in sustainability and we are proud to partner with them to deploy 25 zero-emission electric buses, made right here in the U.S.," said Proterra CEO Ryan Popple. "With zero tailpipe emissions, electric buses help cut transit pollution and improve local air quality for the community." SEPTA's Southern District is located at 20th and Johnston Streets in South Philadelphia.
