Sarawak People's Energy Party

Back then, TERAS was a splinter political party of the Sarawak Progressive Democratic Party (SPDP). It was founded by disgruntled leaders led by William Mawan Ikom following a leadership crisis within the SPDP. The party was later joined by elected representatives from the Sarawak United People's Party (SUPP).^[3] The leadership of the party was supportive of the then ruling Barisan Nasional (BN) coalition. However, their application to become a BN component party was rejected by the coalition.^[3]

TERAS succeeded in attracting a total of 11 elected representatives to join the party in May 2014. However, Wong Soon Koh and four state assemblymen who defected to the party decided to quit TERAS to join the United People's Party (UPP), an offshoot of SUPP. An arrangement was made between TERAS and Barisan Nasional for the division of seats to be contested in the 2016 Sarawak state election.^[4][5] On 11 May 2016, the party's leadership decided to officially dissolve itself to allow their members, who were elected as direct BN candidates, to join any Sarawak-based component within the coalition.^[6] However, the plans were put on hold and then cancelled following the developments of the 2018 general election.^[7]

Banyi Beriak, who was the founding Secretary General of TERAS when it was formed in 2013 before quitting in 2018 to join the UPP and later the PSB, announced on 28 October 2021 that he had left PSB to return to TERAS to take over the presidency of the party.^[8] He then announced in December 2021 that the party would field candidates in the 2021 state election only to be canceled due to a lack of preparations by the party.^[9]

Some true speculations that TERAS will be fully rebranded in a new name as TERAS Plus (TERAS+), as Sarawak prepraring for the upcoming 13th Sarawak general election.
