2.1.1.3. Electricity generation. After treatment, the LFG is introduced into a gas generator set specifically designed for operation using LFG. The engine parts are hardened against corrosive elements to resist the impurities that usually appear in this type of fuel, the low heating value and fluctuating gas quality and pressure. Two internal combustion engines, Caterpillar and GE-Jenbacher generators reciprocating engine (engine/generatorsystem) with an electrical generation capacity of approximately 1.0 MW each. The specific biogas consumption for electricity generation is nearly 550–600 m3/MWh.
