Why You Should Choose a Meter Manufacturer with MID Module B + D Certification for Your AMI Project

If you’re planning an AMI (Advanced Metering Infrastructure) project for a utility, industrial facility, or renewable energy application, choosing the right energy meter manufacturer is one of the most important decisions you’ll make. Energy meters provide the measurement data that supports billing, energy management, and regulatory compliance. Therefore, selecting a manufacturer with proven metrological competence and a robust quality management system helps reduce project risks and improves long-term reliability.

For EPC contractors integrating metering into substations, switchgear, or distributed energy projects, working with a manufacturer that has completed the MID Module B + Module D conformity assessment provides additional confidence in both product design and manufacturing consistency.

What MID Module B + D Means

The Measuring Instruments Directive (MID) is the European legal metrology framework for measuring instruments, including electricity meters.

For electricity meters, MID conformity assessment consists of different modules. Module B is the EU Type Examination, where a Notified Body assesses and approves the meter design against the applicable MID requirements. Module D covers production quality assurance, requiring the manufacturer’s quality management system and manufacturing process to be assessed and periodically supervised by the Notified Body to ensure that production meters remain consistent with the approved type.

Together, Module B and Module D demonstrate not only that the meter design complies with the applicable requirements, but also that the manufacturer’s production process is capable of consistently producing compliant products.

Why This Matters for AMI Projects

AMI projects require more than accurate measurement. Utilities and EPC contractors also expect consistent product quality, complete technical documentation, reliable production capability, and long-term supply stability.

A manufacturer that has completed the MID conformity assessment process is generally better prepared to provide:

• Consistent production quality
• Complete technical documentation
• Traceable manufacturing processes
• Support for project compliance requirements

These factors help reduce risks during procurement, installation and project acceptance.

Why the Manufacturer Matters

Successfully completing MID Module B + D requires significant investment in product development, testing, quality management, and manufacturing control.

Manufacturers with this capability typically have established design verification procedures, production quality systems, and experience working with notified bodies and international certification requirements. This can simplify documentation review and technical communication during international utility projects.

What to Look for in a Meter Manufacturer

When selecting a meter manufacturer for an AMI project, consider whether the company:

• Has completed MID Module B + D conformity assessment
• Maintains an audited production quality system
• Can provide complete technical and certification documentation
• Has experience supplying utility-scale AMI projects
• Provides technical support throughout the project lifecycle
