TATC - a global network of Transformer Engineers Supporting Utility Clients.

With resources position in disparate global locations, TATC can expedite resources as needed and do so cost effectively. With our RMS Energy alliance in the US we can offer an extended scope of services including substation services and product solutions.

After many years as a dedicated transformer design Engineer, I realized there was a need for Utility clients to be represented by qualified, independent and professional Engineers to ensure they receive the best transformer deliverable, built to their specification without compromise.
I embarked on developing a lean and efficient collective of transformer Engineers with unparalleled experience in the trade.
