ATS (Applied Technical Systems Joint Stock Company) was found in 1998 and since then has established our position as a provider of solutions for Substation Automation and Power System Control.

We have steadily grown since our start as the exclusive distributor of Schweitzer Engineering Laboratories (SEL) in Vietnam. We serve industrial customers through the support of SEL products and technical services, at the same time research and develop complete substation automation systems predicated on new design and approach concept. The Integrated Control and Protection System @Station® is one such solution offered tailor-made to customers.

ATS successfully launched the first @Station® system, at small scale, in 2001 at 220kV Vinh Long Substation. The first large-scaled @Station® system was installed and operational in 2003 at 220kV Thu Duc Substation - the largest substation in Vietnam - marking the beginning of ATS’s success in the Substation Automation System field.

Since then, ATS has become increasingly reputed as the credential vendor of substation automation technology amongst international players. We have acquired an unrivaled track record in successful execution of SAS projects for 110kV to 500kV substations in Vietnam.

Our aim of date is to be the leading vendor for the Smart Grid evolution in Vietnam. This movement started with our first SCADA product being operational in 2008, registered with @SCADA+ trademark. In addition, other products and solutions are continuously in development to meet the various demands in the power system and real-time management market. With this current product base and further intensive innovation effort, we will play a proactive role in the Smart Grid movement of Vietnam’s power system.
