Findings from the Newton-Evans Research Company study completed in February 2015 indicate that a substantial number of electric utilities are using distribution automation technologies such as FDIR/FLISR and VVC/VVO/CVR, but the number of operating feeders currently configured with these features is still relatively low. These observations are based on a survey of 75 electric T&D utilities in the U.S. and Canada providing electric power service to 32 million customers (approximately 20% of North America’s electricity end users, according to Newton-Evans estimates.)

Percentage of all feeders that have Fault Detection Isolation Restoration (FDIR) or Fault Location Isolation Service Restoration (FLISR) Capabilities
On a summary basis, nearly one-third of the responding utilities (32%) cited their operation of one or more primary distribution feeders configured with FDIR/FLISR capabilities. However, the overall installed base of feeders with FDIR/FLISR capabilities was quite small, standing at about five percent of the total number of feeders operated by these utilities. According to the survey sample, six percent of 13-15kV feeders and seven percent of 22-26kV feeders are configured to provide FDIR/FLISR functionality.

Percentage of feeders that support integrated Volt/VAR control (VVC), Volt Var Optimization (VVO), or Conservation Voltage Reduction (CVR)
Just over half of all respondents reported having at least some feeders supporting Integrated Volt/Var Control, Volt/Var Optimization (VVC/VVO) or Conservation Voltage Reduction (CVR). The 75 respondents indicated an installed base of 34,122 feeders across 4 voltage levels: 4kV (5,094 feeders), 13kV/15kV (22,831 feeders), 22kV/26kV (4,214 feeders), and 33kV/38kV (1,983 feeders). Overall, respondents indicated that 32% of all feeders currently support VVC, VVO or CVR, but out of 4,214 feeders at the 22/24kV level about 59% support these capabilities.

VVOpie1

Percentage of utilities integrating VVC, VVO or CVR by year end 2017
Overall, 68% of the utilities replying to this question indicated that at least some feeders will support integrated IVV control/VVO and/or CVR by year-end 2017.

Decision factors for implementing VVC/VVO
Respondents indicated that “cost savings effected by reducing the need for infrastructure enhancements” was the single most-cited driver for volt-Var optimization (VVO) implementation, as reported by 38% of respondents. Additional cost savings brought about by “reducing the need for additional generation” was second in importance, at 33%. About 1 in 5 respondents also cited “regulatory compliance” as a significant driver for implementing VVO.

Other reasons mentioned for implementing include peak shaving to reduce demand costs, reducing losses, and maintaining power factor. A few utilities mentioned that VVO is either not a requirement for them or that they do not want to implement additional technology simply to raise revenue.

Findings Corroborate Earlier Newton-Evans Studies Regarding “Mixed” Placement of Controls of Field Devices

The Newton-Evans Research Company today released key findings from its newly published study of electric utility plans for distribution automation. Entitled “North American Distribution Automation Market Assessment and Outlook: 2015-2017” the 89-page report includes coverage of more than 35 DA-related issues.

Progress Being Made with Distribution Automation Programs:
North American utilities are making good progress in developing and implementing new DA applications and telecommunications network upgrades. The overall DA market among North American utilities is approaching one billion dollars and will continue to grow each year for the foreseeable future.

DA Controls Placement:
The placement of DA controls for field devices remains mixed. While some see controls being distributed to field locations, others are placing controls on substation automation platforms, while an even larger group is using control center systems-based approaches (centered on SCADA-DMS systems).

The outlook for controls placement in the future shows that utilities are bringing more controls for fault detection, isolation and service restoration (FDIR/FLISR) and for volt/var control (VVC) into the control center as shown in these charts.

FLISRcontrols VVCcontrols

Automatic Fault Sensing:
Devices providing information such as hot line status and fault indications are becoming a mainstay in many utility DA programs. IOUs and Canadian utilities were more likely to be using automatic fault sensing devices than were their counterparts at electric cooperatives or public power utilities. Usage patterns and plans for AFS devices were strongest among the respondent subgroup of very large utilities (those serving more than 500,000 customers). Of the subgroup using AFS devices, about one-third actively utilize the status of such devices in their DA schemes.

Integration of Communications and Controls for Distributed Generation into DA System Architecture:
By year-end 2014, only about 16% of utilities indicated some use of DA-related communications/controls while another 14% plan to integrate these for DG purposes by year-end 2017. In a related question, well over one third of the respondents indicated that they have a trial deployment to manage distributed energy resources within the DA system either underway or planned.

More than 30 additional topics are covered in the 2015-2017 Newton-Evans DA report. Seventy five major and mid-size utilities were surveyed and interviewed to gather the information for the report. This group provides a substantial sample, accounting for 20% of served customers and 19% of primary feeders across North America.

A supplemental North American DA market outlook synopsis for the years 2015 through 2020 will be released in March. The outlook supplement will provide DA market outlook information based on type, size and regional location of utilities.
