Mavrorachi LFG Power Plant was constructed during 2017-2020 (including licensing and so on) and is operated 24/7/365 by highly specialized scientific and technical personnel of HELECTOR SA, since August 2020. The plant is located in Mavrorachi Landfill, in the greater area of Langadas Municipality of Thessaloniki. The landfill is operating since 2008 and municipal solid waste (MSW) from Thessaloniki is disposed daily.

There are three CHP units type Jenbacher JGC 416, with electrical output of 1,173 MW each and the corresponding permit is up to 3,52 MW power. The power plant is individually interconnected with HEDNO medium-voltage substation near Liti village. The landfill gas produced in the landfill cells is collected and transferred to the power plant, renewable electrical energy is generated, so -with LFG combustion- greenhouse gases emissions are avoided (specifically, methane CH₄), significantly improving the quality of air. The Operation and Maintenance personnel are skillful with expertise on gas engines, supporting the local community in many aspects.
