The company builds transformers and also develops transmission lines as an EPC contractor. In Ethiopia, TBEA was in 2009 awarded the contract to develop the transmission line to Addis Ababa for the Gilgel Gibe III Dam. In September 2010 in Zambia, the state power company ZESCO signed an EPC contract with TBEA to build 334 million USD 330 kv high voltage transmission lines, which would supply power to Eastern, Luapula, Northern and Muchinga Provinces. The project held a groundbreaking on July 2012. The project is to include two transmissions lines: one from Pensulo substation in Serenje to Kasama via Mpika, another transmission line from Pensulo substation to Chipata via Msoro and extension of the existing Pensulo substation to accommodate the two transmission line bays.
Outside of China, TBEA is also coming up with a manufacturing base for transformers, solar equipments & cables in Gujarat, India. The Indian division is registered under the name TBEA Energy (India) Pvt Ltd and will cater to India, African, Middle East and other markets.
