  • Partnered on five renewable natural gas projects to help connect sources of RNG with end-users via the Company's natural gas distribution systems. These five projects are estimated to produce over 17.6 million therms of RNG per year – enough to fulfill the energy requirements of nearly 10,900 homes for one year.
  • Helped fleet customers reduce nearly 59,000 metric tons of greenhouse gas (GHG) emissions by providing over 27 million therms of natural gas to be used as compressed natural gas (CNG) in place of diesel fuel. This is equivalent to removing 12,635 gasoline-powered passenger vehicles from the road for a year. The deployment of renewable natural gas (RNG) to fuel fleets will further drive down emissions and benefit customers and the communities we serve.
