Boardwalk Pipeline Partners, LP (NYSE: BWP) is a midstream master limited partnership that provides transportation, storage, gathering and processing of natural gas and liquids for our customers. Through our subsidiaries, we own and operate approximately 14,195 miles of interconnected natural gas pipelines, directly serving customers in thirteen states and indirectly serving customers throughout the northeastern and southeastern United States through numerous interconnections with unaffiliated pipelines. We also operate more than 255 miles of natural gas liquids (“NGLs”), olefins and brine pipelines, including one of the most extensive ethylene distribution systems in Louisiana. Our subsidiaries' storage facilities have an aggregate working gas capacity of approximately 207 billion cubic feet (Bcf) and liquids capacity of approximately 18 million barrels.
We serve a broad mix of customers, including producers, local distribution companies (LDCs), marketers, electric power generators, direct industrial users and interstate and intrastate pipelines. We provide a significant portion of our pipeline transportation and storage services through firm contracts under which our customers pay monthly capacity reservation charges (which are charges owed regardless of actual pipeline or storage capacity utilization). Other charges are based on actual utilization of the capacity under firm contracts and contracts for interruptible services. Contracts for our services related to NGLs are generally fee based and are dependent on actual volumes transported or stored, although in some cases minimum volume requirements apply. For the twelve months ended December 31, 2013, approximately 81% of our revenues were derived from capacity reservation charges under firm contracts, approximately 12% of our revenues were derived from charges based on actual utilization under firm contracts and approximately 7% of our revenues were derived from interruptible transportation, interruptible storage, parking and lending (PAL) and other services.
