Provider List

Iowa Code Section 476.87 requires the Iowa Utilities Board (Board) to certify all competitive natural gas providers and aggregators (CNGPs) (as defined in Iowa Code Section 476.86) providing natural gas services to customers in Iowa.  The complete rules concerning certification can be found at 199 IAC 19.14.

Application Forms

There are three different application forms available—one for each of the services an applicant is seeking to provide as described below. All forms are provided in MS Word format.: 

Form for Small Volume Users
Usage does not exceed 25,000 therms in any month and does not exceed 100,000 therms in any consecutive 12-month period.

Form for Large Volume Users
Usage exceeds 25,000 therms in any month or 100,000 therms in any consecutive 12-month period.

Form for Vehicle Fuel Providers
A CNGP under Iowa Code section 476.86 that owns or operates facilities to sell natural gas as vehicle fuel to a retail end user.

CNGPs must receive a certificate from the Board in order to provide competitive natural gas services to Iowa retail end users.  A list of currently certified providers, previously certified providers, providers with cancelled certificates and pending applications is available for viewing or download.  The list also includes the rate-regulated natural gas utilities that provide unregulated competitive natural gas services.  Pursuant to Iowa Code §476.86(2)(a), a certificate is not required when competitive natural gas services are provided by a rate regulated natural gas utility.

Applications for certification must include an application fee of $125, made payable to the Iowa Utilities Board, to cover administrative costs.  During the certification proceeding and after certification, applicants and CNGPs are required to notify the Board of any material change in the representations and commitments required for certification within 14 days of the change.  Material changes requiring notification include, but are not limited to; CNGP name changes, changes in CNGP business structure, changes in CNGP ownership, and for Vehicle Fuel Providers, the opening of additional fueling stations or the closing of fueling stations.  Once a CNGP has been granted a certificate to provide natural gas services in Iowa, the CNGP is required to file an annual report by April 1st each year detailing monthly sales volumes and revenues. 

The Board will act on applications within 90 days unless the Board determines that an additional 60 days is necessary.  Applications will be considered complete and the 90-day period will commence when all required materials have been submitted.  If the filing is deficient, applicants will be notified and given 30 days to remedy deficiencies.
