The ACQ-PRO is an EMPIR Project, jointly founded by the European Union and the participating countries. The overall objective of the project is to provide trans-European access to AC quantum voltage standards, to increase research capacity and to establish the basis for future collaboration between metrological institutes working on AC quantum voltage standards. With this in mind, project tasks were designed. This paper describes the objectives and the first outcomes of the project. The most remarkable achievement are the results of experimental research visits working on ACQ voltage standards. The design of a new AC quantum voltage standards easier to integrate and operate that with the BIPM participation will be validated by a pioneering intercomparison. Besides a Good Practice Guide on the use of AC quantum voltage standards is under preparation. Two working groups on ACQ voltage standards and on cryogenics applications will be created within the activities of the project. Finally, the participant Institutes are establishing the strategic plans to ensure the coordinated developing of future AC Quantum Standards.
