Western Power Distribution have given consent to the IMP® to be installed without further witness testing. This effectively verifies the export limitation capability of the IMP® illustrating that sufficient numbers have been installed to make WPD comfortable.
Wattstor has developed the IMP® as a smart export limiter which has the capability to switch-on specific loads in properties during times of excess renewable generation. It has recently been launched and is currently available to renewables installers across the UK.
Currently the local Distribution Network Operator (DNO) has set thresholds for the amount of generation that can be exported to the grid. This has meant that households and businesses have been restricted to the amount of generation that can be installed on their properties (usually 4kWp for a typical household single phase connection).
The IMP® guarantees that no more than the specified generation is exported to the grid. However this export limiter goes one step closer than turning off the generation – it redirects excess generation to specific electrical loads and appliances. This means that households and businesses can install more than the specified generation dictated by the DNO in addition to enjoying the financial benefits gained by using up to 90% of their renewably generated electricity.
