Where is EMSA’s work focus over the next few years?
A new Policy Brief gives an overview of EMSA’s work focus until 2029 and highlights relevant work outcomes to date.
What have we learned about motor systems’ efficiency in the past 15 years and how has EMSA contributed to that?
Looking back over the past 15 years, experience shows that collaboration across governments, industry and experts — supported by sound analysis, aligned standards and practical tools — can help improve the efficiency of electric motor systems. EMSA has contributed to this shared learning by providing evidence, guidance and platforms for exchange, supporting ongoing efforts to improve policies, standards and real-world outcomes worldwide.
Electric motor systems efficiency standards, digitalisation & demand flexibility
An EMSA workshop will be held on 23 February 2026 in Vienna. The workshop language is German.
How to compare air compressor energy efficiency—globally and consistently?
EMSA conducted an international round robin testing programme and developed a guide to the measurement of packaged air compressor specific energy and isentropic efficiency based on ISO 1217:2009. An Excel calculation tool has been developed to perform the stepwise calculation of the isentropic efficiency based on test results as specified in ISO1217.
Electric motor systems – a key element on the way to global net zero
EMSA released a Policy Brief, assessing the importance of electric motor systems in the global energy system. In 2023, electric motor systems were responsible for 53% of global electricity consumption. Their share in electricity consumption varies widely across sectors: 72% in industry, 36% in buildings, 87% in agriculture and 86% in the transportation sector.
Next international conference on Energy Efficiency in Motor Driven Systems (EEMODS)
The next EEMODS takes place on 19 – 21 May 2026 in Berlin. Abstracts can be submitted until 31 January 2026.
Australia no longer member of EMSA
The Government of Australia withdraws from EMSA, following which EMSA has 9 members.
New report evaluates the flexibility potential of heat pumps and electric vehicles
In a new report, commissioned by the 4E TCP EDNA Platform and the Users TCP, the Austrian Institute of Technology conclude that policy and behavioural measures are as important as technical ones.
New insights on industrial Silicon Carbide Variable Speed Drives
EMSA just released a new report with the results of a test series of industrial Silicon Carbide Variable Speed Drives, revealing clear efficiency advantages, but also the need for further research on challenges.
Canada joins EMSA
EMSA is happy to welcome its new member country Canada, represented by Natural Resources Canada.
IC 2023 Nucleus Lab Comparison Report – Part 2 Published
Today, the SSL Annex has published the Nucleus Laboratory Comparison report – Part 2 of the 2023 Interlaboratory Comparison (IC 2023). IC 2023 is investigating the degree of agreement in the measurements of temporal light modulation
Comparing standard IGBT and silicon carbide (SiC) Variable Speed Drives in pump systems
As part of a Swiss research project, a motor system using silicon carbide (SiC) MOSFET-based Variable Speed Drive was evaluated against a conventional system with insulated-gate bipolar transistor (IGBT) technology. Energy loss measurements from both systems were used to estimate the potential savings if all speed-controlled pump drive systems worldwide were converted to SiC technology. The results point to a global annual savings potential of 17 – 25 TWh.
New PECTA Policy Brief published: Circular Economy – Compatible Power Electronics and New Application Areas
The latest policy brief from PECTA, ‘Circular Economy – Compatible Power Electronics and New Application Areas’ has been published and is available for download here.
System-level Energy Efficiency Policy Modelling and Monitoring
A new report, commissioned by the 4E TCP, explores opportunities to improve the energy efficiency of systems using modelling and monitoring in regulations. The learnings found in the report were applied to an electric motor related case study system: compressed air systems.
Webinar 27 June: Understanding data centre electricity use in the AI era
The IEA’s Digital Demand-Driven Electricity Networks (3DEN) Initiative, the IEA 4E TCP Efficient, Demand Flexible Networked Appliances (EDNA) and the Super-Efficient Equipment and Appliance deployment (SEAD) initiative are co-organising a webinar focused on the electricity use of
How to set Minimum Energy Performance Standards for electric motors, Variable Speed Drives, pumps, fans and air compressors?
U4E released its updated Motor Policy Guide and Model Regulations to support policy makers in developing countries and emerging economies in transitioning to energy-efficient motor systems.
How to overcome the barriers to the adoption of Wide Bandgap Industrial Variable Speed Drives?
The adoption of Wide Bandgap (WBG) semiconductors in industrial Variable Speed Drives (VSDs) presents multiple advantages, including improved efficiency, reduced cooling requirements and smaller form factors. Despite their numerous advantages, the adoption of WBG industrial VSDs faces several challenges.
New report: Overview of Flexibility Platforms
New EDNA report examines the ability of ‘flexibility platforms’ to unlock demand flexibility from appliances in the household and commercial sectors. Download here.
New report released: AC/HP Test Methods 2.0 – Phase 4 findings
4E TCP has developed a new test procedure to better reflect the benefits of dynamic load control, beyond a test which locks the fans and compressors at a fixed speed. This report provides the results of a round-robin testing across multiple international laboratories to evaluate the reproducibility and representativeness of this new Test Method for AC/HP products.
