Renewable Energy - Biogas Power
Mistral, a wholly owned Malaysian subsidiary
of Timah, is principally engaged in the
business of renewable energy generation. Mistral operates
a Biogas Renewable Energy Plant (“Plant”) in
Malaysia, with nominal capacity of up to 3 Megawatt (“MW”)
to be upgraded soon to 3.8MW. The Plant uses Palm Oil Mill
Effluent to produce Methane Gas, which is then used as fuel
to run Gas Engines to generate green and renewable energy.
The Plant is located at Km 63 Jalan Sandakan, Lahad Datu,
Sandakan in the State of Sabah, Malaysia, and next to the
Prolific Yield Palm Oil Mill owned and operated by CGB that
has a processing capacity of 90 Metric Tons of Fresh Fruit
Bunches (“FFB”) per hour.
Previously POME from this Mill was treated in a conventional
open lagoon system with the biogas produced being emitted
to the atmosphere. The Biogas Plant provides more efficient
and controlled treatment of POME, whereby methane is captured
and converted in gas engines into electricity.
Mistral has entered into a Renewable Energy Power Purchase
Agreement (“REPPA”) with Prolific Yield Sdn.
Bhd. (“Prolific Yield”) for a period of 21 years.
On 9 February 2015, Mistral has obtained the Feed-in Approval
from the Sustainable Energy Development Authority Malaysia
(“SEDA”) to supply electricity to the national
grid at the Feed-in Tariff rate.
Mistral’s Biogas Plant, being CDM-approved, is a showcase
of how biogas renewable energy can be harnessed sustainably
from palm oil mills in Malaysia.
The Biogas Plant employs an efficient biogas digester system
based on thermophilic digestion, which harnesses methane
generated during anaerobic digestion of POME. The system
involves primary and secondary digester tanks with flexible
membrane roofs for controlled thermophilic digestion.
The captured biogas or methane is utilised for power generation
in gas engines. Biogas that cannot be utilized for energy
production is flared in a closed flare system. Treated wastewater
from the Biogas Plant undergoes further treatment in an
effluent polishing plant and the sludge is then used for
The production process of biogas contributes to Greenhouse
