New Haven's Role in Regional Energy Supply
New Haven Harbor is one of the busiest ports in New England and a critical hub for petroleum products. Fuel terminals along the harbor receive gasoline, diesel, heating oil, and other products by ship and distribute them by truck and pipeline throughout Connecticut and beyond. Natural gas, delivered through interstate pipelines, heats many homes and businesses in the city. Together, these systems keep the region running, especially during cold New England winters.
The companies below were selected for their role in the local energy supply chain, reliability, customer service, and their importance to New Haven's economy.

The oil and gas supply chain includes terminal operators that store and distribute fuel, pipeline companies that move natural gas and petroleum products, local distribution utilities that deliver gas to homes, and retail providers that sell heating oil, propane, and transportation fuels. Each link plays a role in ensuring reliable, affordable energy.
