Case Study: Union Pacific – Long-term Fueling Options

Union Pacific has always looked for the best approach to long-term fueling options because fuel is a substantial portion of operating expenses. This effort included alternative energy long before it became a mainstream topic. Union Pacific is the only major railroad worldwide with extensive gas turbine experience, kicking off a project for gas turbine-electric locomotives as far back as 1952.  In 2002, Union Pacific tested the world’s first diesel-battery, hybrid-switch locomotive, and in 2005 Union Pacific acquired its first Green Goat. Similar in concept to a hybrid automobile, which relies on both a gasoline engine and a battery-powered electric motor, the Green Goat depended entirely on its small diesel-powered engine to charge onboard storage batteries. Funding purchases on its own and in collaboration with governmental agencies, Union Pacific brought 21 Green Goat locomotives on property in California and Texas. After more than a decade of testing and use, Union Pacific discontinued operation of the Green Goat due to reliability issues. Even so, the company sees Green Goats as another valuable building block to finding the optimal fuel mix for emissions and operational performance. Knowing that each fuel has a different impact on various emissions, Union Pacific anticipates a combination of fuels and technologies will power tomorrow’s railroad.

Procter & Gamble to Make Iconic Brands Including Tide and Dawn with Wind Power 

CINCINNATI, October 20, 2015 /3BL Media/ – Procter & Gamble (P&G) announced today plans to meet its electricity demands by using 100 percent wind power to make iconic Fabric & Home Care brands, such as Tide and Dawn. This is possible thanks to a new partnership with EDF Renewable Energy (EDF RE) which will see a new Texas based wind farm generate 370,000 MWh of electricity each year. The wind farm will be fully operational in December 2016.

The partnership was announced at the White House today, as P&G became a signatory of the ‘American Business Act on Climate Pledge’. As part of the pledge, P&G agreed to achieve 30 percent renewable energy to power its plants globally by 2020, with a long term vision to use 100 percent renewable energy. This comes on the heels of a September announcement where P&G committed to reduce absolute greenhouse gas emissions by 30 percent by 2020.

One of the key actions on the journey to rely more on renewable energy is to partner with EDF RE to build a wind farm in Cooke County, Texas. This will generate 370,000 MWh of electricity per year – enough to meet electricity demands for all of P&G’s North American Fabric & Home Care plants, where iconic brands such as Tide, Gain, Downy, Dawn, Cascade, Febreze, and Mr. Clean are produced.

The amount of power generated from the partnership will be equivalent to avoiding more than 200,000 metric tonnes of CO₂ emissions annually. This equals one percent of the national annual reduction target for electricity emissions called for in the White House Clean Power Plan.

The electricity consumption of the plants makes up about half of their total energy consumption. The electricity will be exclusively generated by wind power. The plants will also continue to use natural gas for process heating and comfort heating during winter.

Speaking about the project Shailesh Jejurikar, North America Fabric Care President, P&G, commented: “I am delighted that our collaboration with EDF RE continues to provide our consumers with their favorite, high performing brands while reducing our environmental footprint.”

He continued: “At P&G, when it comes to sustainability, actions speak louder than words and this move is a significant milestone in delivering that promise. It is incredible that the wind farm will generate enough electricity for all our P&G Fabric and Home Care plants; to put that in context: This is enough electricity to wash a million loads of laundry.”

Tristan Grimbert, CEO and President of EDF RE states:  “The participation of P&G to directly procure wind power is a concrete action that demonstrates their understanding of the benefits of renewable energy.  Wind not only emits zero greenhouse gas emissions, but also delivers long-term energy price stability,” he continues “P&G is leading one of the fastest growing markets in the renewable energy space and we are pleased to be their partner to reach their climate pledge goals.”

To celebrate the scale of the collaboration, P&G Fabric & Home Care and EDF RE have constructed a mini-wind farm in Washington DC. The installation is placed on the lawn in front of the Capitol Building and is made up of thousands of spinning pinwheels.

Case Study: Procter & Gamble – Biomass Burner

Procter & Gamble (P&G) has a successful biomass burner at its Albany plant in Georgia. The plant is located in an excellent region for both woody wastes and agricultural residues. P&G direct fires pecan hulls, peanut shells, pallet scraps, sawdust, and other forestry residues, procured from several local companies, in a stoker-type boiler. The plant uses the steam that is produced from the biomass burner for the manufacturing of paper products. The biomass boiler has been in place since the 1980s and delivers strong cost savings when compared to natural gas combustion.

Case Study: Solar Installation Partnership

Case Study: Perdue Farms, Inc. – Solar Installation Partnership

Perdue Farms, Inc. partnered with a utility and a solar integrator in 2011 to develop two solar projects at its corporate offices in Salisbury, Maryland (1.3 MW) and a feed mill in Bridgeville, Delaware (1.6 MW). Perdue entered into a power purchase agreement (PPA) where it provided land, and third parties financed, installed, and maintained the project. Perdue purchases all power. In addition to being financially beneficial and providing a strong price risk management tool, Perdue views the projects as a key part of their overall renewable portfolio and sustainability initiatives.  The projects also contribute to a compelling and visible corporate message regarding its commitment to renewable fuels.
