Juniata energy conversion: a sustainable business solution

Norfolk Southern in 2015 launched a two-year energy-conversion project at its Juniata Locomotive Shop that demonstrates the company’s commitment to improved operating efficiencies and stewardship of resources.

The $53 million project replaces the facility’s heating and power systems, installing 21st century energy technologies to extend the life of a locomotive complex that has served America’s freight rail needs since the late 1800s.

During 2015, NS replaced three 1950s coal-fired burners with cleaner, more efficient natural gas heaters. The company began installing a 1.2 megawatt combined heat and power unit that runs on natural gas and generates enough electricity to carry the complex’s base power load – reducing reliance on the regional utility’s power grid.

The project significantly reduces NS’ environmental impacts. In 2015, largely as a result of the Juniata conversion, NS reduced by 39 percent its Scope 1 emissions associated with the company’s use of coal for energy. NS generated 17,464 metric tons of CO₂ equivalent emissions from coal use, down from 28,570 metric tons in 2014. In addition, replacement of leaky pipes that transport steam water for shop operations is expected to save about 49 million gallons of water annually.

An NS investment in Pennsylvania

A complex of 16 shops, with 30 acres under roof, the Juniata Locomotive Shop in Altoona, Pa., is the largest locomotive repair facility in North America, with a Norfolk Southern workforce of about 950 mechanical employees. Juniata is NS’ primary shop for engine overhauls and midlife tune-ups and is headquarters for the company’s locomotive rebuild program – one of the largest railroad recycling programs ever.

Visit NS’ 2015 sustainability report to learn more about how employees refurbish and outfit 1980s and 1990s model locomotives with upgraded engines that are cleaner-burning and more fuel-efficient. The rebuild program and energy-conversion project represent long-term investments to continually improve NS’ sustainability and business performance.

Cutting costs and energy use with lighting, HVAC upgrades

Norfolk Southern’s energy services group in 2015 continued a long-range plan to improve energy efficiency in railroad facilities. The effort aims to cut operating costs, decrease electricity use, and reduce environmental impacts associated with carbon emissions.

Lighting efficiency

In 2015, the group oversaw lighting and HVAC replacements that are expected to generate annual energy and maintenance savings of more than $2.1 million.

The lighting projects equipped 31 facilities across the system with replacement bulbs and fixtures that last longer, use less energy, and emit a spectrum of light that enhances safety and security of night operations. The projects included seven NS intermodal facilities and yards in Chicago; its Harrisburg, Pa., intermodal facility; and its Shelbyville, Ky., auto mixing center.

By reducing the demand for power generation, the lighting projects are generating carbon savings equivalent to the energy needed to provide electricity to 1,409 homes for a year.

HVAC efficiency

The energy group’s systematic approach to its heating, ventilating, and air-conditioning efficiency program looks for total building solutions to replace aging, uneconomical HVAC systems. In 2015, the group completed projects targeting natural gas conversions from fuel oil, reconfiguration of ducting, and the addition of system controls. HVAC replacement systems had an average seasonal energy efficiency rating of 18, better than the industry standard 13.

In addition to operational and environmental savings, the HVAC projects enhance working conditions for yard and shop employees.

Energy upgrades at NS’ Atlanta office earn rebates

As part of energy-efficiency upgrades in 2015 at its operations headquarters in Atlanta, Norfolk Southern earned more than $20,820 in rebates through Georgia Power’s Commercial Energy Efficiency program. Improvements to the Goode Building in Midtown included installing more efficient lighting, lighting occupancy and daylight sensors, and variable frequency drives on heating and air-conditioning equipment.

The upgrades are expected to reduce the high-rise building’s annual energy use by more than 654,000 kilowatt-hours, lowering emissions of carbon dioxide equivalents by 540 metric tons. That’s equivalent to the typical annual energy use of more than 50 residences in the region.
