What was the original design and construction of the plant?
The planning and construction of the Tallinn Power Plant were driven by the Volta company, which initiated the project following a decision by the Tallinn City Council in 1912. This municipal decision was the culmination of work conducted by a special committee that had been established in 1909 to assess the city's energy needs. The design of the power plant was handled by Volta, with the architectural responsibilities assigned to Hans Schmidt.
When the power plant was officially opened on 24 March 1913, it was designed to be fired by coal. The initial equipment installed at the facility included three Laval-type steam turbines, each with a capacity of 250 horsepower (0.19 MW). These turbines were paired with three electric generators, also rated at 250 horsepower (0.19 MW) each. All of these turbine and generator units were produced by the Volta company itself. To support the steam generation process, the plant was equipped with two coal-fired boilers, which were manufactured by AS Franz Krull.
The 1913 commissioning marked the beginning of the plant's operational history, establishing it as a key energy infrastructure asset for Tallinn. The initial configuration of three turbines and three generators provided the foundational capacity for the city's early electrical grid. The use of coal as the primary fuel source at inception was a standard choice for early 20th-century power generation, leveraging the existing supply chains and technological maturity of coal-fired steam technology. The location adjacent to the Tallinn Gas Factory allowed for potential synergies in fuel storage and distribution, while the former Stuart fortress provided a spacious and centrally located footprint for the industrial complex.
How did the fuel source and capacity evolve?
