What are the challenges to revenue metering for utilities?
Challenge 1:
I need a meter to send real time data to my existing SCADA and other software systems.
Solution:
EIG’s revenue meters support multiple communication modes designed specifically to bring data back to SCADA and other real time telemetry. The meters offer RS485, RS232, ANSI Type 2 Optical port, and Ethernet. Protocols include customizable Modbus, DNP3, and IEC 61850.
Additionally, the Shark® 270 meter offers under-glass 4G wireless cellular communication.
The meter can also be read using EIG’s software or other third party systems, such as Itron’s MV90, and they are compatible with the EnergyPQA.com® AI driven cloud-based energy management system.
Challenge 2:
To improve response time, I need to provide analysis of my utility customer’s power problems, quickly.
Solution:
Replace older revenue meters with power quality recording meters to get immediate information concerning the customer’s circuit issues. Both the Shark® 270 meter and the Nexus® 1272 meter have multiple power quality monitoring features, including waveform recording of 512 samples/cycle to monitor meter customer’s power quality or substation fault on the line.
The meters provide COMTRADE and PQDIF support. They offer harmonics recording, power factor analysis, and alarm emails on power quality events.
Challenge 3:
I need my meter to be cyber secure to protect critical metering data from hacking and tampering and to meet NERC CIP compliance.
Solution:
The Shark® 270 Cyber secure revenue meter offers encrypted usernames and passwords to protect against unauthorized access, an anti-tampering system events log that records all transactions in the meter, and role-based security configurable to the specific application. Digital firmware signature ensures firmware integrity when updating the meter’s firmware, and IP allow lists ensure access only by known users.
Both the Nexus® 1272 meter and the Shark® 270 meter have hardware locks and sealing switches to render remote changes to programmable settings virtually impossible.
Challenge 4:
My critical metering of large loads and tie points requires high accuracy.
Solution:
The Nexus® 1272 meter achieves a 0.06% energy accuracy using a unique and patented auto-calibration metrology. This ensures highest accuracy over temperature and time.
The Shark® 270 meter is ANSI C12.20 0.1% Accuracy Class certified to meet the highest ANSI standard for accuracy.
Both meter models meet or exceed IEC 62053-22 0.2S Class accuracy.
Challenge 5:
I need to standardize on a versatile meter, so that my limited resources are not stretched any thinner.
Solution:
EIG’s MeterManagerPQA® software provides automated maintenance, troubleshooting, and easy access to the entire fleet of meters. It lets you minimize staff resources by using preloaded profiles to configure large groups of meters.
Since EIG’s Shark® 270 meter is field-upgradable to more advanced features, it eliminates the need to stock multiple types of meters. Just upgrade to the features you need when you need them.
Challenge 6:
I need to provide access to metering data without letting my customer into our network or giving my customer access to the meter.
Solution:
With EnergyPQA.com®, a utility customer and a utility account manager have access to a cloud software instead of the meter itself. Eliminate security issues while providing comprehensive data access through the cloud.
Provide customers with energy usage analysis and comparisons enterprise wide.
Predictive analytics AI pinpoints demand reduction opportunities by informing customers of new predicted peak demand, days in advance.
Use C-Suite reporting to identify corrective action to increase energy efficiency and reduce power quality risk in the worst enterprise circuits with C-Suite Reporting.
Provide deep insights into power quality to prevent downtime and improve efficiency.
Send alarm emails on fault conditions, limits, and new peak and predicted peak demand to respond before problems escalate and cause power outages or damage to equipment.
Additional Benefits of EIG’s Revenue Meters
Unique Screen Designer enables you to create custom screens to display any needed data.
The Nexus® 1272 meter supports multiple I/O modules. The Shark® 270 meter has built-in I/O as opposed to expansion modules and superior keystone connectors for I/O.
The Shark® 270 and Nexus® 1272 meters come in socket and switchboard forms.
The switchboard form has a draw out case that allows for easy testing and retrofit.
Shark® 270 vs. Nexus® 1272 – Which Revenue Meter Fits Your Application?
Selecting a revenue meter starts with the application and its measurement requirements. The Shark® 270 combines revenue grade accuracy with flexible communications, I/O, and cybersecurity capabilities. For applications requiring more extensive power quality analysis, the Nexus® 1272 adds auto calibrating metrology and advanced monitoring capabilities.

Frequently Asked Questions
What is a revenue meter used for in electric utilities?
Electric utilities use revenue meters wherever energy measurement has a financial impact. They record electricity delivered or received for billing and settlement, including at customer service entrances, generation facilities, substations, and utility interconnections where a high level of measurement accuracy is required.
What is the difference between a revenue meter and a standard power meter?
The primary difference is the application and required accuracy. Revenue meters are designed for billing and settlement and typically meet specified accuracy standards. Standard power meters are commonly used to monitor electrical conditions, equipment performance, energy consumption, and other operational parameters within a facility.
What is the difference between revenue metering and submetering?
Revenue metering provides the measurements used for utility billing or financial settlement between parties. Submetering tracks energy use beyond the main utility meter, often by tenant, department, building, or load. That information can support cost allocation, energy management, and usage analysis.
How do I choose the right revenue meter for my application?
Start with the application. Accuracy class, electrical system configuration, communications protocol, I/O, and data logging requirements can narrow the choices. Utility tie points and critical billing applications may also call for advanced power quality analysis, cybersecurity features, or bidirectional energy measurement capabilities.
How often should a revenue meter be tested or calibrated?
There is no single testing interval that applies to every revenue meter. Requirements vary according to the meter, application, utility procedures, operating environment, and applicable standards. Testing schedules should follow regulatory requirements, established maintenance practices, and the meter manufacturer’s recommendations for the application.
Can revenue meters be used at utility tie points and substations?
Yes. Revenue meters are commonly applied at substations, utility tie points, generation facilities, and other locations where energy exchanged between systems must be measured accurately. Depending on the installation, requirements may include bidirectional measurement, interval data, communications, and advanced power quality monitoring.
