Prof. Plohl postavio je temelje elektrifikacije Savske banovine i time bitno pridonio primicanju najsiromašnijih, posebice seoskih domaćinstava, bogatstvu, zdravlju i obrazovanju. Za elektrifikaciju osnovao je Bansko električno poduzeće (BEP) u listopadu 1937. i bio mu predsjednik do tragične pogibije u rujnu 1939. Zajedno s organizacijom Seljačka sloga uspio je u dvije godine elektrificirati općinu Vojni Križ, započeti izradu projekta hidrocentrale u Triblju i idejno zasnovati elektrifikaciju željezničke pruge Sušak–Zagreb. Cijenu elektrifikacije seoskih domaćinstava smanjio je 5–6 puta! Vlasnici elektrifikacijskih poduzeća pobojali su se da će ostati bez planirane dobiti, pa su angažirali inženjera Ivu Radulovića, direktora Elektre–Sušak, da održi stručna predavanja u kojima će diskreditirati postavke elektrifikacije BEP-a. Razvila se žestoka novinska polemika Plohl–Radulović koja je detaljno opisana u članku. Prof. Plohl set down the basis for the electrification of the Sava Banate (banovina) and in doing so significantly contributed to the improvement of the wealth, health, and education of the poorest households, especially in rural areas. He founded the Banal Electrical Company (Bansko električno poduzeće – BEP) in October 1937 and served as its chairman until his tragic death in September 1939. Together with the Peasants’ Concord (Seljačka sloga) organisation, within two years he managed to electrify the Vojni Križ Municipality, initiate he construction of the hydroelectric power station in Tribalj, and set down a plan for electrifying the Sušak–Zagreb railway. He managed to decrease the cost of electrifying rural households five- to sixfold! The owners of electrification companies feared they would lose their planned income and thus employed engineer Ivo Radulović, director of Elektra–Sušak, to hold professional lectures in which he would discredit the BEP’s tenets of electrification. This paper also describes in detail a heated polemic between Plohl and Radulović that developed in the newspapers.
