Electric utilities around the world are deploying a wide range of technologies for distribution, transmission and advanced metering systems. These new devices, applications, sensors and monitoring capabilities are geared toward making the grid "smarter" and to support operations, planning and asset management. The ever-increasing amount of data resulting from these new technologies and need for more sophisticated analytics capabilities is presenting new opportunities as well as some challenges for the utility industry. This report analyzes a survey deployed to utility companies to evaluate the past, present and future outlook on "big data" for the industry.


The survey was established to collect information about existing transmission and distribution related systems, applications, architectures, and data sources that are either presently installed or planned for installation in the next five years. The objectives of the survey were to identify (T&D as well as AMI) applications and their uses for modernizing the grid, and opportunities, benefits and challenges associated with new technologies and data sources.


Survey responses were collected in March 2013 via an online surveying tool from utility industry personnel around the world. The survey was divided into four sections as follows: general "big data" analytics readiness level, understanding existing and future applications and data sources, "big data" benefits and opportunities, and "big data" challenges.


The survey respondents spanned 8 countries with the majority of respondents representing the distribution side of the grid. The survey results provide a snapshot into the utility industry's past, present, and future data readiness and data applications as well as opportunities and challenges facing the industry.

Applications, Value, and Use

The results of the survey were used to help inform part of the overarching project plan for EPRI's Distribution and Transmission Modernization Demonstration projects. The report provides a snapshot of the benefits, opportunities and challenges related to the data increase as summarized from the survey results.
