    nuclear power plants

  • Fossil fuel and nuclear power plants are todays major source of electricity as they offer superior availability and cost-effectiveness.

    You need efficient solutions to manage and optimise your electrical systems entire life cycle from design and optimal operations, to maintenance and upgrades to avoid failures which could result in the loss of revenue or penalties.

    A power plants electrical power system delivers the produced electricity to the grid. It also supplies the power which is crucial to running the plant itself. This dual-function electrical infrastructure is vital to all power plants.

    The construction period of these large, complex power plants is also critical. They have to be brought on-line as fast as possible while maintaining a high safety level and respecting the environment, without jeopardising equipment quality and system reliability.

    To meet all these challenges, you can turn to Alstom Grid. We are a committed partner who know how to supply electricity to your plant and deliver your electricity to the grid, whatever the type of power plant you operate - conventional, gas or nuclear.

    Meeting the challenges...World electricity demand continues to grow. The total electricity consumption will increase by 66% between 2008 and 2030. In developing countries, the growth can be doubled.

  • Coal-firedCoal is the predominant source of electricity around the world (34% of electricity generation), far ahead of nuclear or gas. This is because the process of generating electricity from coal is well known and, of course, coal is inexpensive and plentiful. Coal-fired power plants are large, complex projects in which the electrical systems play a key role in timely commissioning and long-term availability.

    Alstom Grid engineering and project management expertise ensure smooth management of the electrical systems supply and installation.

    Whatever type of power generation...

    GasBecause of its low capital cost and limited environmental impact, the share of natural gas in global electricity generation has grown rapidly. It is projected to reach 22% by 2030. Open or combined-cycle power plants often have a short construction schedule. Here again, the electrical systems contribute substantially to plant rapid commissioning and its long-term availability.

    Alstom Grid engineering and project management know-how will help you streamline the supply and installation of the necessary electrical equipment.

    NuclearAround 14% of the worlds electricity comes from nuclear power plants. As nuclear power emits no greenhouse gases, and uranium resources are essentially inexhaustible, this clean generation is expected to expand significantly in the coming years, buoyed by climate change concerns and the rising cost of fossil fuels. The electrical systems of nuclear power plants are subject to a very stringent product qualification process.

    Alstom Grid has vast experience in supplying equipment to nuclear power plants, particularly in China, France and Germany.

  • Alstom Grid is your ideal partner for all types of power generation projects. Our highly-trained and seasoned project managers will scope your solution from beginning to end, including how your power plant will fit in the network. Electrical engineers in our network Consulting department create the most logical, cost-effective and ecological transmission evacuation system moving the energy from your generation point to end users.

    They will develop the entire scheme to move your generated energy to its distribution points using virtual simulation and short-circuit studies. In doing so, they integrate cutting-edge technologies and ensure that losses are kept to an absolute minimum.

    Alstom Grid solutions are also adapted to meet the growing demand and anticipate future developments, assuring your network has a long life cycle.

    Project management has quality assurance high on its list. With Alstom Grids project management know-how and experience, you know that your network is in safe hands, that skilled people are doing the work, that the highest standards and values are being applied to ensure that your system will operate exactly as designed.
