Grid Export Limiting Solution - Maximise Capacity on Site

CleanEarth can enable customers to maximise their renewable energy potential on site using an export limiting technology.

Government policies are encouraging companies and landowners to be environmentally conscious and install renewable energy to reduce carbon emissions. However, the electric grid distribution system was originally designed for energy to flow in one direction – from the power station to the home / business – and not to flow both ways. As such, the UK grid system has physical constraints in relation to the distribution of energy generated.

Many applications for renewable energy come with two options from the Distribution Network Operator (DNO):

  • Pay a large amount to upgrade the local network or transformer to enable the renewable energy installation to take place, or
  • Restrict your installation to a certain size according to exported power restrictions

Until now, many businesses and landowners have not been able to install the size of renewable energy system on their sites that matches their demand because of these constraints and / or associated grid upgrade costs. At CleanEarth we are changing this for our customers by utilising a new technology.

  • Solution for Commercial Customers

    This technology enables clients to install the renewable capacity that matches their demand profile without being affected by the DNO export limit and without the need for costly upgrade costs.

    For example, a site with a very small export capacity can install the volume solar panels that they require, and use export limiting technology to manage the amount of power that is exported.

    Our customers are able to benefit from increased energy capacity at their site and utilise the valuable grid resource effectively.

  • Solution for Landowners

    Export limiting technology allows customers to switch between technologies. We currently have five wind turbine customers with applications in planning for solar PV to be installed alongside their turbines. It will allow them to use both technologies, depending on the weather conditions and the output of each system. For example, on a sunny day with light winds, when the turbine may have a low output, the solar panels will be allowed to produce enough energy to reach the power capacity for site.

    Our customers will be able to benefit from increased energy capacity at their site and utilise the valuable grid resource effectively.
