Natural Gas Investments

​Reliability Projects

Delmarva Power manages more than 3,460 miles of natural gas lines to deliver safe and reliable service for 132,000 customers in New Castle County, Delaware. Over the last five years, we have invested hundreds of millions of dollars in our system to maintain safe and reliable service and continue to meet growing demand for natural gas. These investments include conducting regular inspections, performing preventive maintenance, modernizing existing natural gas lines as needed and installing new natural gas lines across our service area. We are making excellent progress in the modernization of our system. Each year, we replace more than five miles of natural gas main to enhance safety, durability, and reliability and we have already replaced more than two-thirds of the cast-iron and bare-steel natural gas main on our system.

For larger projects, we work to minimize impacts to the local area and provide advance notice to customers about upcoming work. We also coordinate closely with state and local officials, including water and sewer replacement programs and street rehabilitation and paving programs in the City of Wilmington and other local municipalities. If you have questions about a project in your area, please contact Customer Care at 1-800-375-7117 or e-mail​

New Castle Area Natural Gas Reliability Project

To enhance and further modernize our natural gas system, we are installing a new natural gas main in New Castle, Delaware. The project will connect two existing underground natural gas lines and is needed to transport natural gas across our system so it can be delivered to customers' homes and businesses. The project will provide much needed additional capacity in our natural gas delivery system, helping meet the energy needs of our customers and growing demand for natural gas in northern Delaware. Construction will begin December 2018 and the project is expected to be in-service by the end of the winter.
