Role of the Commission

The Delaware Public Service Commission regulates only the distribution of natural gas to Delaware consumers. The delivery and administrative costs associated with natural gas distribution are determined in base rate proceedings before the Commission. The recovery of costs associated with the natural gas used by customers is determined annually as part of fuel adjustment proceedings. As a result of this process, rates for natural gas will typically change at least once a year. Fuel adjustment rates for natural gas may also change during the annual recovery period when the projected recovery of gas costs exceeds limits set for the over or under-collection of gas costs. Occasionally, natural gas distribution companies are permitted by their tariff to collect additional fees, often called 'riders', to recover unanticipated or extraordinary expenses. For instance, both regulated natural gas distribution companies have an 'environmental rate rider' to recover costs associated with the clean up of pollution from old manufactured gas sites. These rider rates are determined in separate proceedings before the Commission.

The Commission does not regulate the costs charged by propane gas providers: questions related to propane costs should be directed to the specific provider. The Commission does administer the Natural Gas Pipeline Safety Program for the U.S. Department of Transportation's Office of Pipeline Safety which relates to the operation of both propane and natural gas distribution systems.
