Alstom is a French multinational company which holds interests in the electricity generation and rail transport markets. According to the company website, in 2012–2013 Alstom had annual sales of €20.3 billion, and employed approximately 96,000 people in around 100 countries. Alstom's headquarters are located in Levallois-Perret, west of Paris. Its CEO is Patrick Kron.Alstom is active in the fields of electrical generation and transmission, with products including turbines for hydroelectric, gas, coal and nuclear-powered plants, as well as large-scale electrical grid infrastructure, solar-thermal, and geothermal systems. It is also a major rail vehicle manufacturer, active in the fields of passenger transportation, signalling and locomotives, with products including the AGV, TGV, Eurostar, and Pendolino high-speed trains, in addition to suburban, regional and metro trains, and Citadis trams.Alstom was formed from a merger between Compagnie Française Thomson Houston and the Société Alsacienne de Constructions Mécaniques in 1928; significant acquisitions included the Constructions Electriques de France , shipbuilder Chantiers de l'Atlantique , and parts of ACEC SA . A merger with parts of the General Electric Company plc formed GEC-Alstom in 1989; the company became Alstom in 1998.In 2004, Alstom was in financial crisis due to massive inherited unexpected costs arising from a design flaw inherited from the acquisition of ABB Group's turbine business, in addition to losses in other areas of the business. The company required a €3.2 billion state-backed bailout in 2003 – and as a result was required to sell several divisions including shipbuilding and electrical transmission to comply with EU rules on state aid.In 2014, Alstom and General Electric announced that a US$17 billion bid for the company's power and grid divisions had been made and provisionally accepted. The proposed takeover became a political issue, with the French state intervening, enacting a decree, nicknamed décret Alstom, giving the French state additional powers to veto foreign takeovers. GE's bid was later modified, matching elements of a rival offer from Siemens and Mitsubishi Heavy Industries – with proposals to form 50:50 joint ventures in several divisions; the modified bid was also accepted by Alstom's board – at the same time the French state took a 20% stake in the company from Bouygues in order to protect its position. The GE acquisition deal for the power and grid division is expected to be finalized by early 2015. Wikipedia.

In order to unlock the full potential of Europes offshore resources, network infrastructure is urgently required, linking off-shore wind parks and on-shore grids in different countries. HVDC technology is envisaged but the deployment of meshed HVDC offshore grids is currently hindered by the high cost of converter technology, lack of experience with protection systems and fault clearance components and immature international regulations and financial instruments. PROMOTioN will overcome these barriers by development and demonstration of three key technologies, a regulatory and financial framework and an offshore grid deployment plan for 2020 and beyond. A first key technology is presented by Diode Rectifier offshore converter. This concept is ground breaking as it challenges the need for complex, bulky and expensive converters, reducing significantly investment and maintenance cost and increasing availability. A fully rated compact diode rectifier converter will be connected to an existing wind farm. The second key technology is an HVDC grid protection system which will be developed and demonstrated utilising multi-vendor methods within the full scale Multi-Terminal Test Environment. The multi-vendor approach will allow DC grid protection to become a plug-and-play solution. The third technology pathway will first time demonstrate performance of existing HVDC circuit breaker prototypes to provide confidence and demonstrate technology readiness of this crucial network component. The additional pathway will develop the international regulatory and financial framework, essential for funding, deployment and operation of meshed offshore HVDC grids. With 35 partners PROMOTioN is ambitious in its scope and advances crucial HVDC grid technologies from medium to high TRL. Consortium includes all major HVDC and wind turbine manufacturers, TSOs linked to the North Sea, offshore wind developers, leading academia and consulting companies.

Five DSOs (CEZ distribuce, ERDF, EON, Enexis, Avacon) associated with power system manufacturers, electricity retailers and power system experts, propose a set of six demonstrations for 12 to 24 months. Within three years, they aim at validating the enabling role of DSOs in calling for flexibility sources according to local, time-varying merit orders. Demonstrations are designed to run 18 separate use cases involving one or several of the levers increasing the local energy system flexibility: energy storage technologies (electricity, heat, cold), demand response schemes with two coupling of networks (electricity and gas, electricity and heat/cold), the integration of grid users owning electric vehicles, and the further automation of grid operations including contributions of micro-grids. The use cases are clustered into three groups. Three use cases in Sweden and the Czech Republic address the enhancement of the distribution network flexibility itself. Five use cases in France, Germany and Sweden demonstrate the role of IT solutions to increase drastically the speed of automation of the distribution networks, which can then make the best use of either local single or aggregated flexibilities. Ten use cases in Czech Republic, France, The Netherlands and Sweden combine an increased network automation and an increased level of aggregation to validate the plausibility of local flexibility markets where both distributed generation and controllable loads can be valued. Replicability of the results is studied by the DSOs and industry with an in-depth analysis of the interchangeability and interoperability of the tested critical technology components. Dissemination targeting the European DSOs and all the stakeholders of the electricity value chain will be addressed by deployment roadmaps for the most promising use cases, thus nourishing the preparation of the practical implementation of the future electricity market design, the draft of which is expected by end of 2016.

The PINTA Project (IP1 Traction TD1 and Brakes TD5 Phase 1) will address the two key topics highlighted in the first Shift2Rail Call topic S2R-CFM-IP1-01-2016 Development of concepts towards the next generation of traction systems and management of wheel/rail adhesion, namely Traction and Adhesion Management. Traction subproject will focus on the improvement of seven technical and economical performances of the Traction system that have been agreed and defined in Roll2Rail. These performances have to be improved on five different train applications having different constraints, needs and specificities, from tramway to HST, including metro, sub-urban, regional trains. In particular, Traction sub-project will address the following: 1) Line capacity increase through weight, volume and noise savings of Traction equipment. 2) Operational reliability increase via higher reliability/availability. 3) Railway system LCC reduction As far as Adhesion management is concerned, the work will lead to the achievement of a number of important objectives linked to Brakes, such as Improvement of braking degradation limit in poor adhesion condition Management of all adhesion conditions in a way that brake distances are optimized Improvement of the overall train safety, which relies substantially on the management of the wheel/rail contact Reduction of wheel Life-Cycle-Costs (LCCs) through optimized wheel/rail contact in braking The activities should contribute in formulating new performance specifications for Adhesion Recovery Systems. Moreover, improved requirements for Wheel Slide Protection test procedures should be developed, followed by new specifications for Automatic Test benches.
