Battery Monitoring System for NERC PRC-005-6 Compliance
Model # EE-NERC-BMS
The EE-NERC-BMS is an all-in-one battery monitoring solution designed to meet NERC Standard PRC-005-6 Table 1-4(f) “Exclusions for Protection System Station DC Supply Monitoring Devices and Systems” with no maximum maintenance interval. This table outlines that “no periodic maintenance” is required if monitoring and alarming occures for the following battery parameters: string voltage & current, cell/unit voltage, cell/connection resistance, cell & ambient temperature, electrolyte level, and ground fault status.
Implementing 24/7/365 battery monitoring alleviates the need for regularly scheduled, on-site visits to meet NERC compliance. A complete picture of battery health is available remotely for each system outfitted with monitoring; this includes alarming, reporting, and trending. The EE-NERC-BMS will ensure battery reliability while lowering the maintenance costs of critical backup battery systems.

What is NERC?
NERC (North American Electric Reliability Corporation) is a not-for-profit regulatory authority that ensures the reliability of the Bulk Power System in North America by enforcing Reliability Standards.
What is NERC Standard PRC-005?
PRC-005 is the standard for Protection Systems Maintenance and Testing. PRC-005 continues to be the most commonly violated reliability standard in North America.
What is NERC Standard PRC-005-06?
NERC Standard PRC-005-6 requires utilities to document and implement programs for the maintenance of all protection systems affecting the reliability of the Bulk Electric System (BES). All VLA, VRLA and NiCad Batteries are required to be verified, inspected, monitored & calibrated to meet PRC-005-6 Compliance.
Does Eagle Eye offer monitoring and testing solutions for IEEE requirements?
Yes, visit our IEEE Solutions page to view our solutions.
What parameters does the EE-NERC-BMS measure?
Collectively the BQMS, ELM-Series, and GFM-100 measure the following parameters: string voltage, string current, cell/unit voltage, cell/unit resistance, cell/unit temperature, positive & negative ground fault, electrolyte level, and ambient temperature.
What components are included with the complete EE-NERC-BMS kit?
The complete kit includes all of the required installation materials for the BQMS, ELM-Series, and GFM-100. This includes all cabling between the monitors and the battery system. Installation materials are custom prepared per order based on a site survey.
How are the components of the EE-NERC-BMS mounted?
The full kit includes (3) separate monitors for each component which can be wall mounted independently. Alternatively, the monitors can be shipped pre-installed in an enclosure which can then be mounted as desired by the end user.
How do the components connect to each other for communications?
Both the ELM-Series Electrolyte Level Monitor and the GFM Ground Fault Monitor include (4) Form C contacts. These contacts are wired through the BQMS Battery Monitoring System. From there, the following Form C output contacts will be available: string voltage, string current, cell/unit voltage, cell/unit resistance, cell/unit temperature, 1-3+ low electrolyte level, 4+ electrolyte level, 1-3+ electrolyte temp., 4+ electrolyte temp., positive ground fault, negative ground fault.
- Real-time monitoring eliminates required on-site maintenance activities such as routine manual battery testing
- Included battery management software allows remote monitoring and alarming of all battery systems
- Generate reports and view historical measurement data at any time, such as during a NERC audit
- Designed for use in utility environments, the EE-NERC-BMS is available in an industrial enclosure
- Installation can be performed while the system is online, eliminating the need to de-energize the system and bring in a backup
- Ripple removing algorithm to filter out noise and produce accurate results
Eagle Eye's Battery Monitoring System eliminates required maintenance activities - ultimately saving time, money & other resources. Batteries are monitored in real-time eliminating costly consequences. Batteries are the weakest link in the power plant, and are critical to the reliability of the Bulk Electric System (BES). Proper maintenance will prolong the life of the battery system and ensure that the battery will meet expectations.
NERC PRC-005 is the standard for Protection Systems Maintenance and Testing. PRC-005 continues to be the most commonly violated NERC reliability standard in North America. PRC-005-6 requires utilities to document and implement programs for the maintenance of all protection systems affecting the reliability of the Bulk Electric System (BES). All VLA, VRLA and NiCad Batteries are required to be verified, inspected, monitored & calibrated to meet PRC-005-6 Compliance.
In December 2013, a FERC order approved PRC-005, defining minimum maintenance activities and maximum maintenance intervals for stationary batteries that went into effect February 24, 2014. PRC-005 also outlined exclusions to maintenance intervals for sites using real-time battery monitoring systems. By using real-time battery management solutions, utilities in compliance with NERC can decrease the cost of compliance by automating many of the required tasks. The enforcement date was on April 1, 2015 - which is the the first date entities must be compliant with part of the standard. The implementation plan for PRC-005-6 includes specific compliance dates and time frames for each of the requirements.
