Bestium Corporation Sdn. Bhd. (BCSB) was incorporated in October 1989 to market and implement the then new emerging renewable energy industry in Malaysia. With the availability of abundant sunlight in Malaysia throughout the year, Solar Photovoltaic (PV) was identified as the most feasible renewable energy solution to meet the requirements of rural and remote electrification in the country. Thus making BCSB the pioneer Solar PV company in the country.

In early 1999, as part of BCSB’s diversification program, the company ventured into the telecommunication sector. BCSB quickly established itself as a key telco player in the supply and installation of microwave and related  telco products for all the major telcos in the country. We have since branched out to providing specialised comprehensive services for telco network management in the country and abroad.

In June 2006, as part of a major shareholders restructuring exercise, Bestium Corporation Sdn. Bhd. (BCSB) was renamed Bestium Technologies Sdn. Bhd. (BTSB). The primary focus on the two main businesses namely power (renewable energy) and telecommunications was maintained.

In July 2010, BTSB ventured into the Energy Efficiency (EE) industry via its subsidary Green Energy Alliance Sdn Bhd. (GEA)
