On the history of the Mittweida power station: Already at the turn of the century, the first plans to build a power station for Mittweida, 1900 acquisition of a plot of land in Neudörfchen including the water rights of the adjacent Zschopau by the city, first in 1908/09 construction of a steam power station as the first expansion stage, the facility was already there Planned as a combined hydropower and steam power plant, the second expansion stage, however, was initially postponed due to the lack of funds for the construction of the cost-intensive hydraulic engineering systems, in perspective steam power should serve as peak power and as a reserve in the event of an accident, trial operation from 1909, regular operation from 1910, coal procurement Railway (Mittweida Industriebahnhof – Ringethal line with the Mittweida power station freight station, built in 1907/08, opened in 1909, dismantled until 1975, the former railway bridge over the Zschopau preserved upstream, the only evidence in the immediate vicinity of the power station s, cf. Object 09305796), on the works track transport to the coal shed, initially isolated operation, i.e. the power plant supplied several communities in the area via long-distance lines with electricity (three-phase current) independently of other power grids, so 1910 connection of the local networks of Kockisch and Seifersbach next to the urban area of ​​Mittweida and commissioning of the Local lighting in Schönborn, Lauenhain, Altmittweida and Erlau, 1911 connection of the local networks of Hermsdorf-Falkenhain, Königshain, Tanneberg and Weißthal, 1914 further expansion of the high-voltage network through the Altmittweida-Königshain and Falkenhain-Tanneberg ring line, 1919 supply of Mittweida and 24 communities in the surrounding area , an increase in output of the power plant was previously only achieved through technical upgrading (swu), followed by a more fundamental expansion of the structural and technical systems to the combined use of water and steam power due to growing demand in a second expansion stage from 1919–1923 When using the favorable location on the Zschopau with a usable gradient of approx. 4.5 m to 100 m to operate a low-pressure turbine system, after construction began in 1919 and a five-month construction stop in 1923, the run-of-river power plant was put into operation, steam power plant continued to operate undisturbed during the expansion, now serving as a power reserve, Disadvantage of such a low-pressure hydropower plant: low adaptability to energy demand, among other things due to fluctuations in the available water flow rate, therefore the supply of steam as (uneconomical) peak power is necessary, but at night and on weekends no use of the power available, for this reason decision in 1924 to upgrade the power plant In a third expansion stage to a pumped storage plant, construction started in 1926, commissioning in 1928, utilization of the basic principle of hydraulic storage in a storage basin above the power plant, filling of the S at night and on weekends storage basin by means of pumps and pressure pipes from the backwater of the run-of-river power plant, at peak load times the stored Zschopau water flows back for the purpose of energy generation by means of high-pressure turbines, the installation of an equalization basin (cf. Pump storage plant Niederwartha) could be omitted due to favorable discharge conditions, 1943 sales and operating community with the Elektrizitätsverband Gröba, for this purpose expansion of a first interconnected line, still 1945 takeover of the power plant by AG Sächsische Werke, from 1949 communal ownership, in January 1953 transfer of the power plant to VEB energy distribution Siegmar, from May 1953 part of the VEB Energieversorgung Karl-Marx-Stadt, from 1954 part of the VEB Energieversorgung Karl-Marx-Stadt, from 1960 structurally assigned to the Freiberg operations department, after World War II decision not to replace the outdated steam power plant, but instead to expand the connection to the state network and to operate the steam power only as a reserve in the event of an accident, for this purpose the addition of a new switchgear house and the installation of a 60 kV switchgear and a 60 kV transformer, in 1958 finally shutdown of the outdated steam power plant, thus scrapping the associated technical systems in the machine and boiler building, at the same time, due to capacity problems, resolution to set up a peak-load diesel power plant in the former boiler house as a fourth expansion stage, commissioning in 1961, diesel generators only rarely in use due to the energy crisis in the 1970s, 1976 first concept for maintaining the diesel and hydropower plant in Mittweida as a technical museum, 1978 inclusion in the Central Monument List (Z) of the GDR, 1984 cessation of operation of the diesel power plant due to unprofitability, 1988 the decommissioning of the pumped storage plant follows, from 1991 extensive renovation work on the structural and technical systems, hydropower plant with two low-pressure turbines still in operation today.

On the construction and technical history of the power plant systems: 1st expansion stage 1908/09 with later extensions (steam power plant): Structural systems: machine house with machine hall and high-voltage switch room, boiler house with chimney and coal shed, also workshop, administration and social rooms, technical equipment at the start of operations: two tandem compound steam engines from HANOMAG (125 or 250 PS), direct coupling with two three-phase flywheel generators (93 kW / 5,200 V or 184 kW / 5,200 V), boiler system from Oschatz from Meerane ( two corrugated tube boilers, each 100 m² heating surface), the perspective installation of a third steam engine including generator and a further boiler was already planned during construction and took place in 1912/13: tandem composite steam engine from Sächsische Maschinenfabrik vorm. Richard Hartmann AG (500 PS), generator from Pöge from Chemnitz, two-flame tube boiler from Oschatz (150 m² heating surface), 1914 replacement of the 125 PS steam engine with a steam turbine from Bergmann Elektrizitätswerke AG Berlin (2,250 PS), at the same time renewal of the switchgear, 1920 equipping the two-flame tube boiler with a hollow grate furnace, in order to be able to use at least some of the brown coal as a substitute fuel in view of the prevailing hard coal shortage (in the final stage all boilers had a hollow grate furnace), 1925 installation of a fourth steam boiler (two-flame tube boiler of the Saxon machine factory formerly Richard Hartmann AG, 150 m² heating surface) as well as a second steam turbine (2,250 PS, Albert Gieseler names 2.239 PS and year of purchase 1926), for this structural expansion of the machine and boiler building to the south, the total output of the four generators was now 3,500 kW, 1948 construction ash removal plant, 1946 dismantling of the steam engine from 1925 as a reparation payment, with the establishment of the diesel engine power plant 1958 shutdown and subsequent scrapping of the technical systems necessary for steam power generation.

2nd expansion stage 1919–1923 (run-of-river power plant): Structural or hydraulic systems: weir system with fixed overflow and movable weir and bottom outlet gate, upper and lower trench, turbine hall and generator house, turbine set in the turbine chambers: two Francis shaft turbines and one Francis - Twin shaft turbine from JM Voith from Heidenheim (usable head H of 4.25 m, volume flow Q of 7.5 or 15 m / s³, designed for a water throughput of 30 m³ / s, total output of 965 kW), on a common horizontal Shaft directly coupled (can be switched off individually by means of a claw clutch), drive of a three-phase synchronous flywheel generator from Sachsenwerk from Niedersedlitz (1,430 kW), 1954 installation of automatic turbine controls, 1965 installation of a semi-automatic computer system from Germania from Chemnitz, 1985 replacement of the small riflemen, 1992 renewal of the computer system, 1994 modernization of the turbine regulator.

3rd stage of expansion 1926–1928 (pumped storage plant): Structural systems: Extension of the generator house in a southerly direction, storage basin, throttle valve building, pressure pipeline (height gradient 115 m), technical equipment in the generator house from 1927: two feed pumps from Voith (according to Albert Gieseler from from Escher-Wyss) to fill the storage basin (delivery of a maximum water volume of 540 l / s), connected to the shaft of the low-pressure turbine system via a gearbox, to be released using a coupling, two high-pressure turbines from Voith (spiral turbines, individually or jointly switchable, 750 or 1,500 PS, 1,000 / min, head 120 m) were used to generate energy when the storage water flows back through the pressure pipeline, directly coupled with two three-phase synchronous generators (900 or 1,830 kW).

4th expansion stage 1960/61 (diesel power plant, replacement of the steam power plant): Structural system: conversion of the boiler house to a machine hall, in it installation of three marine diesel units (type 8 NVD 66A, output 1,500–1,940 kW each), each coupled with a three-phase synchronous Generator (type DFH 206/20, output 2,500 kW each, if required, the diesel engine power system can be switched on within 15 minutes, fuel delivery by train), further installation of associated electrical switching and monitoring systems, ancillary and auxiliary systems, batteries, transformers, after 1980 two of the three diesel units scrapped.
