November 19, 2021. Southwest Gas, the Regional Transportation Commission of Southern Nevada (RTC), and U.S. Gain announced a partnership that will provide RTC’s transit buses with a cleaner, operationally cost-effective fuel source to help reduce greenhouse gas (GHG) emissions and decrease operating costs.

The Public Utilities Commission of Nevada (PUCN)-approved agreement allows Southwest Gas to provide RTC with environmentally friendly renewable natural gas (RNG) to fuel most of the agency’s public transit fleet. U.S. Gain, a sustainable energy solutions provider, was selected to supply the RNG.

RNG can be used in everything that already uses natural gas. Sourced from a variety of organic byproducts, the resulting RNG has a low, neutral, or negative carbon intensity (CI) score depending on its feedstock. The production of RNG itself captures methane that would otherwise be released into the atmosphere while the use of the gas results in carbon dioxide emission reductions when compared to diesel. Southwest Gas has been working with several customers in its service territory who are either RNG developers or organizations seeking renewable natural gas supply.

“Southwest Gas is committed to stewarding a sustainable future through both our operations and the clean and affordable renewable natural gas we deliver to customers. RNG is a powerful solution which will help Southwest Gas customers reduce GHG emissions. At 35 percent, the transportation sector makes up the largest percentage of GHG emissions in Nevada. This important and forward-thinking partnership demonstrates our ability to provide our valued customers and communities with sustainable energy solutions and technologies that are environmentally friendly,” said John Hester, CEO and President of Southwest Gas. “We are committed to providing clean energy for generations to come and are proud to join forces with the RTC and U.S. Gain to help expand sustainable transit options in Southern Nevada.”

“RNG will provide the RTC with the ability to use clean fuel technology that is compatible with existing vehicles and fueling infrastructure,” said M.J. Maynard, RTC CEO. “This is significant as it will help us reduce greenhouse gas emissions throughout Southern Nevada while saving up to $1.2 million in operating costs.”
