Rural electrification, D.R. Congo

Micro substations enables access to electricity

Conventional power transmission and distribution requires a minimum amount of power for grid connectivity to be economically viable. Conventional substations are unsuitable for areas that require relatively small power loads. 

But ABB has come up with an innovative solution that taps into existing high voltage transmission lines located in the vicinity, and in one efficient transformation, steps down the voltage level to provide electricity to small communities living nearby. 

ABB has installed such a micro substation in each of seven rural farming villages in Southern DRC to bring affordable electricity to more than 5,000 people. The project was commissioned by the DRC’s national electricity company, Société nationale d'électricité (SNEL), and leverages funding from the European Investment Bank. 

At the core of the the micro substations is ABB’s  Station Service Voltage Transformer (SSVT), which transforms the power tapped from the high voltage line to low voltage output for use in small communities. If there is an increase in demand for power, additional SSVTs can be paralleled within the same micro substation. These are an ideal solution for rural electrification projects for small communities throughout the world where high-voltage lines are close by, even within 30km. .
