The Federal Energy Regulatory Commission on Oct. 17 authorized National Grid LNG LLC to add natural gas liquefaction facilities at the company’s existing Fields Point facility in Providence, Rhode Island. National Grid proposed the project, which seeks to add a 20 million standard cubic feet per day capacity, at the request of its customers Narragansett Electric Company LLC and Boston Gas Company to enable them to deliver gas to the facility by pipeline in a bid to diversify their supply sources. National Grid owns a 600,000-barrel storage facility and provides LNG storage, vaporization, and redelivery services. Currently, customers truck LNG to the facility for storage, and National Grid redelivers gas via truck or Narragansett Electric’s distribution pipelines and Algonquin Gas Transmission’s interstate pipeline. With the new project, this flow would be reversed, enabling Algonquin to transport gas that Narragansett Electric would deliver to Fields Point for liquefaction and storage. Commissioners Cheryl LaFleur and Richard Glick reiterated their concerns that the environmental review of such projects should include greenhouse gas emissions. The companies are subsidiaries of National Grid plc.
