The global smart meter market exceeded $22 billion in 2025 and is growing at 8.4% CAGR. A handful of companies dominate — but the competitive landscape is shifting fast with Chinese manufacturers gaining ground in emerging markets.
1. Landis+Gyr (Switzerland)
The world’s largest pure-play smart metering company by revenue. Landis+Gyr dominates European electricity metering with the E450/E550 series and has a strong North American presence via its Gridstream RF platform. Key strength: deep DLMS/COSEM compliance and long-standing relationships with tier-1 utilities.
2. Itron (USA)
Itron is the market leader in North America across electricity, gas, and water. The OpenWay Riva platform introduced cellular-native AMI (no gateway required per meter) and has driven significant market share gains. Strong MDM software integration via Itron Enterprise Edition.
3. Kamstrup (Denmark)
The Scandinavian champion with unmatched depth in heat and water metering. The OMNIA platform covers electricity, water, and heat in a single ecosystem — a compelling offer for multi-utility environments. Kamstrup’s ULTRAFLOW water meters are a reference standard in the industry.
4. Honeywell (USA) — Elster Division
Following the acquisition of Elster in 2015, Honeywell has a comprehensive portfolio spanning gas, electricity, and water. The Elster brand remains prominent in European gas metering. Honeywell’s Temetra platform is a leading multi-utility HES/MDM.
5. Siemens (Germany)
Siemens re-entered the meter market aggressively with its eMeter acquisition (now Siemens Energy). Strong in grid-edge intelligence and integration with grid automation systems. Competitive in Southern Europe and Asia.
6. Sagemcom (France)
Dominant in France (Linky meter deployment — 35 million units) and expanding across Southern Europe. The Linky programme validated PRIME PLC at national scale. Sagemcom is a key supplier for utilities that standardise on PRIME.
7. Iskraemeco (Slovenia)
A major European manufacturer with strong presence in Eastern Europe and South-East Asia. Known for competitive pricing and solid DLMS compliance. Growing market share in Middle East and Africa.
8. Hexing Electrical (China)
The largest Chinese smart meter exporter by volume. Hexing has won significant tenders in Africa, South Asia, and Latin America through aggressive pricing and good-enough DLMS compliance. Quality perception has improved significantly since 2020.
9. Holley Technology (China)
One of the biggest domestic Chinese meter manufacturers, expanding internationally. Holds DLMS certification and has been winning tenders in emerging markets where TCO is the primary criterion.
10. Networked Energy Services / NES (USA)
A specialist in utility-grade PLC-over-powerline metering with a strong cybersecurity focus. NES meters are used in critical infrastructure deployments where the utility demands application-layer security by default.
The Emerging Challengers
Watch also: ADD Group (China, aggressive European expansion), Enermet (now Sanxing), and a wave of Indian manufacturers (Genus, HPL, Secure) that are qualifying for large domestic rollouts under India’s RDSS programme (250 million smart meters by 2025–26).
What to Look For When Selecting a Manufacturer
- DLMS CTT (Conformance Test Tool) certificate — not just ‘DLMS compliant’
- MID certificate from an accredited Notified Body (for EU markets)
- Track record with your specific communication technology (PLC/RF/NB-IoT)
- Local support and spare parts availability
- Cybersecurity disclosure — do they publish a SBOM (Software Bill of Materials)?
Frequently Asked Questions
What is the key technical difference between Itron’s OpenWay Riva platform and traditional AMI architectures?
OpenWay Riva is cellular-native and eliminates the need for a concentrator/gateway per meter, whereas traditional AMI requires centralized collection points. This reduces deployment complexity and associated infrastructure costs while improving data latency.
How does Kamstrup’s OMNIA platform provide competitive advantage in multi-utility deployments?
OMNIA integrates electricity, water, and heat metering in a single ecosystem, allowing utilities to standardize on one platform rather than managing separate vendor solutions. This simplifies data integration, reduces MDM complexity, and lowers overall maintenance overhead.
What DLMS compliance certifications should utilities verify before selecting a smart meter manufacturer?
Utilities should specifically request DLMS CTT (Conformance Test Tool) certificates rather than accepting generic “DLMS compliant” claims, as this validates conformance through accredited testing. Additionally, EU markets require MID certification from an accredited Notified Body to ensure metrological accuracy.
Why is Landis+Gyr’s Gridstream RF platform considered a strong choice for North American deployments?
Gridstream RF provides robust RF-based communication with proven long-term stability across North American utility networks, backed by deep DLMS/COSEM compliance and established relationships with major tier-1 utilities requiring enterprise-grade reliability.
What cybersecurity capability distinguishes NES meters in critical infrastructure applications?
NES specializes in utility-grade PLC-over-powerline metering with application-layer security by default and publishes Software Bill of Materials (SBOM) documentation, addressing critical infrastructure requirements where supply chain transparency and default-secure architecture are mandatory.
