3.16 Primary/grid transformer

Tap changer

Please note that should it be determined at detailed design stage that the replacement of the tap changer is not possible due to the unavailability of a compatible replacement that is rated 100% reverse power capable or for any other reason; it will be necessary to replace the associated Primary/Grid Transformer with one that is equipped with a suitable tap changer with 100% reverse power capability rating. The Works, provisional Price and completion date do not currently include the works for the replacement of the Grid Transformer to one that is equipped with a suitable tap changer with 100% reverse power capability rating.   

Adjustment to the price, delivery dates and works 

Once UK Power Networks has completed the detailed design, determined whether or not the Primary/Grid Transformer needs to be replaced and what if any, additional works are required, UK Power Networks will notify You in writing of any associated adjustment to the provisional Price, the completion date and the Works required to reflect the replacement of the Primary/Grid Transformer.
