Together, the two sites will offer 750MW of flexible capacity and 600MWh of storage, with the battery handling instant, short-duration balancing while the generation plant covers extended periods of low renewable output. Wilson Power Solutions supplied the earthing transformers that protect the battery site.
A battery site of this scale depends on equipment that performs reliably when a fault occurs on the network. Our nine transformers provide the neutral earth reference for the site's 15kV system and protect it during short-circuit events. We supplied 33kV Wilson Earthing Transformer, four 15kV Wilson Earthing Transformers, each rated to withstand 1000A for 10 seconds, along with two 250kVA 15kV/415V, and two 500kVA 33kVA/415V Wilson Auxiliary Earthing Transformers, which combine the earthing function with an auxiliary supply for the site's own power requirements.
Once fully operational, the combined Thurrock Flexible Generation facilities will support electricity demand equivalent to that of up to 2.4 million homes, transforming a former fossil fuel site into one of the UK's significant clean energy assets.
