Substations

The substations at the grid-connected wave and tidal sites are broadly similar. They provide isolation switching for the devices under test and operate as the interface between EMEC and the UK national grid.

The electrical output performance of each of the devices is measured by equipment within the substation and transmitted to the data centre. We then analyse the quality of the electricity to demonstrate that the devices can provide a smooth and reliable supply of electricity to the grid.

The metered data is also provided to the developer through the Supervisory Control and Data Acquisition (SCADA) system and the power data is logged in the data historian to be made available for historical trending. We ensure the confidentiality of the data collected.
