The Stadtwerke Pforzheim GmbH and Co. KG (SGP) for the supply of customers in the city of Pforzheim with district heating and drinking water responsible. In addition, they are one of several providers of electricity and natural gas in the Enzkreis .


The first central water supply in Pforzheim was founded in 1875 and was fed by the springs in the Grössel valley. Of the total of 23,000 inhabitants of the city, 17,000 had their own connection at the time.

The city's first power station went into operation in 1894 after a ten-year planning phase.

After the First World War , the citizens' committee of the city of Pforzheim decided to connect the power grid to the overland power supply in Baden . In 1922 almost all municipal businesses had an electricity connection.

On January 1, 1939, the Eigenbetriebsverordnung came into force: With the merging of the supply service providers gas works , water works , electricity works as well as the Pforzheim tram and the Pforzheimer Kleinbahn to Ittersbach , this was the hour of birth of the Pforzheim municipal works. Later they also operated the Pforzheim trolleybus , which ran from 1951 to 1969.

The second half of the 20th century was characterized by the expansion of the municipal utilities. In 1972 and 1983 a 110 kV switchgear house and a 20 kV control center were built. The Enzwerk in Brötzingen - built as a provisional facility in the post-war period - was also expanded and formed the heart of the power supply for three decades. When the company's own buildings were merged on the Enzwerk site in 1980, the old power plant was demolished.

Since 1985 the Pforzheimer Stadtwerke has developed into an energy supplier and service provider for the entire region. In particular, the aspects of efficient energy generation and renewable energies have played a major role in the last two decades. For example, river power plants were built on the Auerbrücke and in Eutingen to generate electricity .

In 2004 the biomass block in the thermal power station was put into operation.
