Energy Metering and Demand Management

SEL Engineering Services creates energy consumption reports, demand management systems, and power control solutions that help decrease operating costs while increasing efficiency and uptime.

We provide these solutions to both producers and consumers of energy. We can apply them as complete systems or integrate them with existing infrastructure, processes, devices, and software.


Whether for new or existing facilities, we can design a system that fits your needs. SEL solutions include the following:

  • Energy invoicing and reporting
  • Revenue and check metering
  • Power quality compliance reporting, including IEEE 519 and EN 50160
  • Peak demand reduction and peak shaving
  • Time-of-use-based energy optimization
  • Multisource control systems that maximize uptime
  • Database and reporting integration with SEL and third-party meters

We can apply these solutions for you in a wide range of settings, including the following:

  • Multibuilding campuses—industrial, manufacturing, college/university, etc.
  • 480 V commercial buildings
  • Transportation hubs
  • Facilities with onsite power generation
  • Utility interconnections
  • DER integration with distribution and transmission grids
  • Grid-level power quality metering and control

A System Ownership Approach

SEL solutions give you the ability to build a complete meter reporting and demand management system on equipment that you own.

You pay a one-time purchase price for highly reliable, substation-grade SEL equipment with a service life measured in decades—an investment that places the system’s return on investment and operational cost savings fully under your control.

The SEL-735 Power Quality and Revenue Meter is the keystone of the system. It exceeds industry standards for accuracy over a wide measurement range and is suitable for revenue metering, power quality monitoring, and a wide array of additional metering applications.

Communications and data concentration are provided by powerful SEL Real-Time Automation Controllers (RTACs) with secure networking. Data is stored on a hardened server-class SEL computing platform, and web access allows viewing from virtually anywhere. And for peace of mind, all SEL equipment comes standard with our industry-leading, no-hassle 10-year warranty and free technical support.

Scalable Solutions

We offer metering asset integration services in three tiers. With SEL devices as a foundation, you can scale up system capabilities as needs dictate and budgets allow.

SEL Engineering Services will consult with you at every stage of the project, from planning and design through commissioning of the system. We’ll install and configure all the necessary equipment, integrate it with your existing infrastructure and processes, and ensure that the whole system meets your economic and operational objectives.

Powerful Data Analysis

SEL meter reporting solutions offer data visualization and analysis capabilities that you can use to drive planning, operations, and billing decisions. We can also help analyze your metering data to better understand your power system assets and processes.


Invoicing image

Monitor, report, and invoice through SEL Meter Reports or perform sophisticated analysis by integrating with other software like Microsoft Power BI.

Power Quality Compliance

Power Quality Compliance

Identify, visualize, and analyze power quality events using the data already available in SEL metering devices.

ITI (CBEMA) curves and detailed voltage event graphs can help plant operators and power producers detect and resolve issues before they affect other systems. The ITI curve classifies voltage events to indicate disturbance severities that cause malfunctions, such as insulation failure, overvoltage trips, or load dropout.

Data Aggregation

Data Aggregation

Manage your entire campus by bringing real-time and historical data together in one place. SEL Real-Time Automation Controllers (RTACs) with our acSELerator Team Software enable automated data collection from field devices and make it available for easy display and analysis.

Energy and Demand Management

SEL solutions can bring meter, weather, and other data together to help you make well-informed energy and demand management decisions.

Optimize plant processes and schedule electric usage to avoid peak demand charges. Use WAGES (water, air, gas, electricity, and steam) system metering to reduce waste and optimize usage of all your energy resources.

Renewable Resource Integration

SEL metering solutions improve reliability and enhance the integration of distributed and variable resources into the bulk power system.

Each SEL-735 meter can handle up to ten simultaneous communication sessions, giving SCADA system operators the real-time data needed to respond quickly to disturbances, reclosing events, alarms, and device failures.

SEL solutions can share intertie data securely with varied privileges, allowing utilities and independent system operators (ISOs) to adjust access as needed.
