The History of Electricity In Mazandaran
There was no electricity in Mazandaran province until 1929 when the first diesel generator with 120 kilowatt capacity, was installed in Gorgan , and was utilized under supervision of municipality, in replace of oil and petroleum that were widely used in Mazandaran. Then following the installation of a diesel generator with capacity of 120 kilowatt in Babol , the third one was installed in Sari with 60 kilowatt capacity. Other cities of Mazandaran exploited similar units under the management of municipalities and private sectors and delivered electricity to different parts of the Province.
The capacity of the generator units did not suffice the increasing demands of customers in all daily hours. Although the electricity was used mainly for lighting , it was not enough to serve the normal diesel generator with consumption of consumers reliably and there was electricity merely in part of the day with very low voltage level and high voltage drop .
