Gas storage facilities play a vital role in ensuring a reliable supply. With proximity to both interstate and intrastate pipelines, natural gas storage facilities provide an efficient and dependable supply of natural gas to consumers, businesses and utilities. Stored gas is particularly valuable when production or delivery is compromised, such as in the aftermath of a hurricane. Additionally, building storage inventory levels in the low demand summer months ensures that sufficient supplies are available for the winter heating season.
