TNB’s LSS Sepang Shows Consistent Operational Performance for 2 Straight Years

24/03/2021

Tenaga Nasional Berhad’s (TNB) maiden large scale solar (LSS) farm in Sepang exceeds its maximum annual energy declared for two consecutive years through smart plant management combined with the adoption of artificial intelligence and data analytics technologies.

For its first operational year in 2019, the solar power plant surpassed its maximum annual energy declared to the off-taker (TNB) by 6% or at more than 110,000 megawatt-hours (MWh).

This commendable operational performance was replicated in 2020, with the solar farm generating 108,900 MWh or 5% more than declared. 

“We are able to optimise this solar farm’s operation by leveraging on data analytics and monitoring technologies,” said TNB Renewables Sdn Bhd (TRe) Managing Director, Mohd Yusrizal Mohd Yusof. TRe is a wholly-owned subsidiary of TNB.

He explained that among others, the technologies used have allowed TNB to calculate the best timing to wash the solar panels based on output levels and weather forecast.
