Electric Utility Rate Demonstration Project: North Carolina, 1977-1978 (ICPSR 7885)

Principal Investigator(s): United States Department of Energy


One in a series of studies on customer response to utility regulatory pricing in early 1975, the North Carolina demonstration project was carried out by the North Carolina Utilities Commission (NCUC) under a cooperative agreement with the Department of Energy. The participating utilities were Blue Ridge Electric Membership Corporation (BREM or BR) and Carolina Power and Light Company (CP&L). Research Triangle Institute (RTI) provided the research and analysis support to the project, and ICF, Inc. consulted on the time-of-use rate design. The experiment lasted from 1977 to 1979 and involved residential customers of the two participating utilities. Four sets of data resulted from the demonstration: questionnaire survey data from the customers, summary demographic information, utility load reports, and customer usage records. (No weather data were collected.) Three of the sets are available in this data collection. Parts 2 and 3 contain 28 days of data, including hourly data. They also contain identifying information that links their data to the pertinent customer/participant's demographic data in Part 1.

Scope of Study

Subject Terms:    consumer attitudes, consumer behavior, demographic characteristics, econometrics, economic behavior, electric power, electric utilities, energy conservation, energy consumption, public utilities, regulation, utility rates

Geographic Coverage:    North Carolina, United States

Time Period:   

  • 1977--1979

Date of Collection:   

  • 1977-12--1979-05

Universe:    Active Blue Ridge Electric Membership Corporation and Carolina Power and Light Company residential utility customers.

Data Type(s):    administrative records data, event/transaction data, experimental data, survey data

Data Collection Notes:

In Parts 1 and 3, data for the two utilities are contained in the same file and are distinguished by the alpha codes BREM or CP&L in variable 1. CP&L customers also have a "1" in the units position of the customer ID number (variable 2). BREM customers have a "2" in this position.

Two of the five segments of the demonstration project series are not represented in this data collection. Customer survey response data were gathered for the North Carolina project but were not made available in this release because of difficulties with the record layout of the data. Weather data were not collected for this project.


Sample:    Stratified random probability sampling.

Data Source:

(1) personal interviews, (2) telephone interviews, and (3) utility usage and load records

Extent of Processing:   ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Standardized missing values.
  • Checked for undocumented or out-of-range codes.
