Power plant design by William H. Lindley

Power plant design by William H. Lindley

According to this design, Warsaw was to be powered by a power plant built in Powiśle district, and the grid voltage was supposed to be 5 k~ on the high side and 120 Y on the low-side of single-phase current. Adoption of the high voltage of 5 kY was an innovative solution at that time, because in those years power plants in Europe were operated at 2-4 kV voltage. Initially, the power plant’s output was planned at 3 MW, and 10 MW in the future.

The Warsaw Power Plant becomes the property of the city

The acquisition of the Power Plant took place on the basis of the judgment of the Regional Court in Warsaw. The initiator of the actions related to the acquisition was the then mayor of the city, Stefan Starzynski. The mayor believed that the Association failed to meet its obligations under the concession, the process of the city’s electrification was behind the city’s development, and the residents incurred unreasonable costs for their access to electricity.

First days of the war in the Warsaw Power Plant

At the outbreak of World War II, the Warsaw Power Plant had 20 boilers and 8 turbine generators, whereas during the siege 4 boilers and 2 turbines were operational. The first days of the war in the Power Plant were quiet, and the whole crew was on their stations. Regular fire aimed at the power plant began on September 7th, but did not cause much damage. During the subsequent attacks in mid-September, a fire broke out on the roof of the engine room. The crew’s actions focused on making sure that the fire does not get through to turbine sets and other devices. In order to prevent flooding by rainwater, employees quickly installed covers made of boards and canvas.

Seizing the Pruszkow Power Plant

Seizing the Pruszkow Power Plant

German troops approaching Warsaw seized the Pruszkow Power Plant. During this seizure, the plant was operational. However, its output decreased due to the damage to the transmission network caused by warfare. After the capitulation of Warsaw, the work on repairing the damage commenced. Among other things, the line connecting Pruszkow with Wola was repaired, which allowed to power the western part of Warsaw.

The bombing and rebuilding of the Warsaw Power Plant

The Warsaw Power Plant was operational until September 28th. On that day, the numerous cases of damage caused by an air-ride made it impossible to restart the power plant. After the Germans had entered Warsaw, the Power Plant was put under military supervision, which was next replaced by the civilian one. In the first months of the occupation, the Power Plant’s crew took mainly to reconstructing the plant and restoring its ability to generate power. Experts from the German company Siemens, brought to Warsaw specifically for this project, took part in the reconstruction of the power plant. Already on October 4th the boiler no. 23 and the 15 MW turbine generator no. 9 were started, and at the end of the year it was possible to connect virtually all consumers to the network.

The occupation vs. the Pruszkow Power Plant

During the occupation, the power plant operated almost at full capacity. Electricity production in 1941 was 86,500 MWh and in 1943 - as much as 110,500 MWh. The crew of the Pruszkow Power Plant also conducted conspiratorial activities. The Home Army underground group was established. It was associated with the 6th Helenow Region, 7th District of the Home Army - “the Collar”. Many commanders of “the Collar” received the so called iron papers issued by the Power Plant, even though they were not in fact employed there. A unit consisting of 45 people was formed on the territory of the Power Plant, code named “Water lily”. The group underwent training and gathered weapons.

Wyzwolenie i plany odbudowy

Wyzwolenie i plany odbudowy

Warsaw is liberated from the Nazi occupation. On the same day the Warsaw power engineers, including those working in the Praga district, reached the destroyed power plant in the Powiśle district to inspect the damage. The destruction of the Warsaw Power Plant was so immense that the authorities even wondered if its reconstruction is at all possible. Opponents of the Power Plant located in the Powiśle district jumped at the chance to get rid of the facility they considered harmful to the city center. The most tenacious advocates of the Warsaw Power Plant’s rebuilding were power engineers themselves, including their first post-war director Stanislaw Beniger. They found that the damage to the turbine sets and boilers was not that extensive, and it was possible to deploy the first devices the very same year.

Effective flue gas desulfurization in the Siekierki CHP Plant

Already in the first heating season, during which we use our newly built wet flue gas desulfurization installation in the Siekierki CHP Plant, we obtain the expected environmental effect. On January 4, 2013 the Inspector of Environmental Protection in the Mazowieckie Province issued an opinion, which confirms the achieved environmental effect resulting from the construction of the wet flue gas desulfurization installation. Sulfur dioxide emissions fell by more than 4586 tons/year. This means that as a result of this investment 70% of the installed capacity is desulfurized.
