PROJECTpipes


PROJECTpipes is a 40-year accelerated pipeline replacement program from Washington Gas to modernize the 1,200-mile natural gas distribution system in the District and enhance overall system resiliency, reliability, and safety for nearly 165,000 gas customers. This accelerated replacement program also helps the District meet its climate goals by reducing potential leaks and methane gas emissions on the distribution system.

In August 2014, the DCPSC
approved the first phase of the PROJECTpipes initiative (PP1) from June 1, 2014, to September 30, 2019, for a total amount of $110 million, along with a substantial package of annual compliance reporting requirements. PP1 was extended for 15 months (through December 2020) while the next five years of the initiative (PP2) underwent rigorous review and consideration. During this intensive review period, the Commission approved an updated total spend for PP1, including the 15-month extension, not to exceed $141.25 million.

As of October 30, 2020, WGL has spent $139.4 million under PP1 and replaced or remediated 20.9 miles of gas main and 4,157 service lines.

In December 2018, WGL filed a
plan with the Commission to implement the next five-year phase of the PROJECTpipes initiative (PP2) to continue its accelerated pipe replacement. The Commission approved a modified PROJECTpipes 2 plan on December 9, 2020, with a surcharge eligible target spend of $150 million for the three-year period from January 1, 2021 to December 31, 2023 and included significant compliance reporting requirements.

To facilitate this substantial investment, the Commission continues to allow WGL to initially recover associated costs through a Commission-approved billing surcharge that appears as a line item on customer bills. During subsequent base rate cases, these surcharges are transferred into regular distribution rates, provided such investments have been undertaken in a prudent manner and are used and useful.
