National Grid continues construction work on the Queens Gas Reliability Project, a multi-million dollar undertaking to modernize the gas system in Queens, improving safety, reliability and supporting the energy needs of the local community. “The Queens Gas Reliability Project is an example of our Connect 21 vision to modernize our energy delivery system and to help customers take control of their energy use,” said Mike Ruiz, director, Community and Customer Management, National Grid. “This project is important to strengthening the network for our Queens customers and it’s a good example of how the company works closely with local communities and City agencies on complex construction projects.” National Grid is investing more than $100 million in the Queens Gas Reliability Project to install more than six miles of new gas mains through Central Queens from Rockaway Boulevard in Southern Queens to just north of the Long Island Expressway to meet the growing energy needs of customers.
