Shtang is pioneering the way to sustainable energy generation. We have constructed the largest power plant in the Middle East based on biogas from sanitary sludge treatment: an anaerobic sludge treatment facility, which co-generates both heat and electricity, to be used in the plant itself and to be sold to the Israel Electric Company.

Shtang was part of a national project of pumped-storage hydroelectricity. This method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost off-peak electric power is used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power.
