Hi bit of an awkward one
A customer has an AD plant generating electricity around 800KVA with the generation / Fit meter fitted to the AD equipment, however the export meter is on the HV side of supply. My customer has been told that there could be a 4% loss by going back through the transformer thus losing money, is this true.

Sounds about right for the transformer losses.
HV tariffs are normaly slightly cheaper when you buy electricity as the electricity company dosent have the transformer losses to pay for. Is the FIT payment the same for LV and HV?

The electricity supplier also does not carry the risk of the transformer failing and need replacement, or have to carry out maintenance on it.

The FIT payment is the same
The customer is thinking of taking the engine out and fitting a 1Meg engine and the point of connection will be at HV. What implications could this have?. They have permission to generate up to 1.5Meg
