Advanced Metering Infrastructure
The “I” in AMI also allows a utility to cost-effectively implement a variety of modern grid applications. EnerNex knows how to help a utility get the most out of the “I” in AMI. Advanced Metering Infrastructure (AMI) consists of everything needed to support advanced metering – from the meter itself to the back-end applications associated with demand response, billing, etc. Effective AMI development, implementation and operation relies on a marriage of electric power engineering with information technology expertise – a key component of EnerNex’s capabilities.
EnerNex provides a wide array of engineering and consulting services geared towards smart implementation of AMI. This covers all phases of AMI project development, including:

For this reason, systematic enterprise architectural (EA) methodologies were developed providing clarity and risk mitigation. EA accomplishes this by focusing upon identifying and translating your organization’s business goals into the requisite business procedures, and underlying automation services.
To minimize risk, EnerNex provides:
IEC 61850 Testing
EnerNex has the largest concentration of IEC 61850 experts in the industry, including four former heads of IEC 61850 software development teams and the original project manager. Our team helped create the standard and continue to participate in its evolution and application.
IEC 61850 presents an attractive standardization scheme for electric power utilities because it defines a single automation technology for the entire substation and has the potential to cut configuration and upgrade costs across the life cycle of the substation by 75% or more. It is an international standard that is accepted and implemented worldwide by all major vendors of control, protection and monitoring equipment. Utilities implementing the IEC 61850 standard are now laying the groundwork for an enterpriselevel common communication infrastructure for electric power utilities. IEC 61850 has the potential to transform the substation like no other communications standard, through “plug and play” automatic configuration, elimination of dedicated protection wiring and the creation of smart instrumentation transformers. It specifies the requirements, engineering processes, supporting tools, system life-cycle, conformance testing and the quality assurance requirements and maintenance for the entire substation automation system.
Services for Utilities
Services for Manufacturers
Our Involvement
Smart Grid Collaborative
Utility investments are usually large. Smart Grid investments are huge and will impact a broad range of stakeholders – and the impact on those stakeholders will be tremendous. The relationship between customers and energy providers will be fundamentally changed. Costs will be certain; however, benefits will be dependent on programs designed for Smart Grid users and customer participation. Customers will have the opportunity to realize significant benefits. Change to the customer-utility relationship brings the potential for confusion, misunderstanding, and risk.
The greatest risk to utilities and consumers is that the investment will not be realized as beneficial to stakeholders to their fullest extent possible. Regulators will also be faced with a bewildering array of smart grid-related policy decisions – on everything from cost recovery, to rate design, to customer data privacy and security. Left to the traditional adversarial process in which stakeholders operate in silos, smart grid benefits can get delayed or never materialize.

Power Systems Projects
Atlanta Hartsfield Airport/Georgia Power Harmonics Analysis
EnerNex worked on a project in collaboration with Georgia Power and the Atlanta Hartsfield Airport to investigate, model and mitigate significant harmonic distortion in the voltage and current cause by the airport’s people mover train system.
These trains have been in service for many years and use an older power electronic technology that causes this problem. Measurements were taken at transformer pads located outside the concourses right at the aircraft gates as well as in the primary substations feeding the airport.
Erich Gunther used the measurements taken to validate the EMTP-RV model of the system. The model was used to design a mechanism for controlling the harmonic distortion.
PacifiCorp
A project led by Erich Gunther, this study of flicker undertaken by PacifiCorp in response to customer complaints about lamp flicker. These complaints are geographically diverse, indicating a transmission-propagated cause. PacifiCorp conducted a series of measurements, which validated the customer complaints. These measurements also indicated that a large steel mill with an arc furnace and a Static VAR Compensator (SVC) in the area could be the primary cause. There was also the possibility of another customer facility contributing to the problem.
PacifiCorp retained Erich to develop an accurate electrical model of the northern Utah area that can predict IEC flicker and harmonic distortion at PacifiCorp’s major load serving substations in the northern Utah area. Once developed the model helped in providing an assessment of the relative contributions of the sources of the flicker. EnerNex staff ran cases with this model to test various solutions to mitigate flicker to acceptable levels.
ISO New England
EnerNex has played a key role in this effort to perform extensive harmonic and transient analysis of the southwest Connecticut power system on behalf of ISO-New England and Northeast Utilities (the operating companies) to evaluate the maximum amount of underground 345-kV cable that could safely be used in a major expansion of that system.
The analysis required running tens of thousands of cases and developing the automation systems to validate and process the results. EnerNex staff also provided expert testimony on the results to the Connecticut Siting Council – the body with the authority to approve the expansion project design. Key elements of the testimony included devising a method to graphically and intuitively describe complex electromagnetic phenomena to an audience of widely varying backgrounds. The Connecticut Siting Council ultimately approved the project as recommended by the operating companies, EnerNex and the other consultants involved in the project (GE Power Systems and PB Power).
Later, EnerNex conducted a feasibility study for ISO-New England on a proposed generator expansion in the area, which would involve additional 345-kV cable. Electromechanical dynamic models of these generators, including the excitation systems, were included in the TOV studies.
Northeast Utilities
Under a blanket order, EnerNex has conducted several transient studies for Northeast Utilities:
- Effect of 345-kV cable installation on distribution feeder arrester applications
- 345-kV cable parameter sensitivity study on temporary overvoltages
- Study of temporary overvoltages on the 115-kV system in southwest Connecticut
- Study of transient recovery voltages associated with 115-kV cable installation
- Temporary overvoltage study of the proposed New England East-West Solutions (NEEWS) project. Model development and benchmarking has been completed, and the study is expected to continue for several more months.
Each study has required the refinement and extension of automated methods to prepare ATP simulation models and to generate reports. These automated methods are essential for quality control and efficiency. The NEEWS project, in particular, has one of the most extensive and detailed models ever used in a study of electromagnetic transients.
Center for Advanced Technology Application (CATA)
EnerNex was one of the original founders, along with the Horizon Energy Group, who founded the Center for Advanced Technology Application (CATA). CATA collaborates with researchers from the Research and Development Consortium of Poland and other worldwide organizations.
The goal of this venture was to develop applications of advanced computation, communications and other technologies to improve the operation of the electric transmission system. CATA focuses on applying the available research in a manner that is actionable and effective.
CATA is a credible source of technical information and services for the ongoing operations and specific transmission system improvement projects.
