RWE in Poland

contentMenu


RWE Stoen Operator manages the Warsaw electricity network and is the operator of the capital’s distribution system.

It delivers electricity to 910,000 customers in Warsaw and its suburbs. By employing highly experienced specialists, making significant investments as well as using the latest sustainable technologies, RWE Stoen Operator maintains the highest network operation standards. RWE Stoen Operator began its operations on 1st of July 2007, as a result of mandatory unbundling of sale and distribution operations, continuing the prior investments in the Warsaw electricity network. Investments in the development and modernisation of the energy infrastructure of the Warsaw network during 2002–2009 exceeded one billion PLN. Future investments until 2015 account for more than PLN 1.095 billion.

The strategic investment projects were focused on the modernisation and expansion of high voltage grid. The “Pałac” 110/15kV substation is unique in Poland, as it is the first underground facility of this type. It was installed in chambers built during the construction of Warsaw subway under the Plac Defilad square. The “Pałac” substation plays an important role in supplying electricity to Warsaw city centre.

The “Pałac” substation for the first time puts into practical use the idea of reutilisation of part of the losses. The power transformer chambers are designed to allow utilisation of heat generated during the operation of transformers to heat other spaces, e.g. the underground parking lot neighbouring the substation. The idea to reutilise the transformer waste heat was subsequently adopted as standard design guideline for new facilities and was implemented in three new substations, i.e. “Południowa”, “Imielin” and “Powiśle”.

In 2006 the high-voltage “Południowa” substation was commissioned, it supplies electricity to the districts of Mokotów, Ochota and Włochy, while in 2008 the “Powiśle” substation was put into operation. It is important to Warsaw, as it improves electricity supply security and powers the districts of Śródmieście and Powiśle. Creating the latest generation distribution substation in a historical building supervised by the Polish National Inspector of Historical Monuments relates to the traditions of the first Warsaw “Powiśle power station”. The building housing the new substation was erected in 1936, right from the beginning it was designed as electrical equipment building and the zoning regulations provided for such use.

In recent years significant land development activities are going on in more remote parts of Warsaw. Housing estates rise quickly, especially around Wilanów district. In response to growing electricity demand in this part of the city RWE Stoen Operator has built the 110/15 kV RPZ Wilanów substation. Its architecture excellently blends with the surrounding buildings of Wilanów City. The Wilanów substation is the latest energy facility in Warsaw. Built in 12 months at a cost of PLN 30 million it was commissioned in December 2009. This unmanned substation was built by RWE Stoen Operator using latest technologies thus – despite its great importance for the Warsaw electricity grid – it is compact in size.

In march 2011, RWE Stoen Operator has commissioned the “Stadion” substation, another investment under the framework of long-term investment programme focused on development of Warsaw’s electricity network. This new investment by the operator of Warsaw’s grid is in line with several infrastructure projects in Warsaw related to Euro 2012. The new substation will provide electricity supply to the National Stadium and the National Sports Centre building complex, and during the Euro 2012 will provide for efficient operation of stadium’s infrastructure. The change will also be noticeable to residents of Praga Południe district – the area to be ultimately supplied by the “Stadium” substation will be between the Wybrzeże Szczecińskie – Starzyńskiego – Kinowa – Ostrobramska streets and indirectly power will flow to more distant parts of Warsaw. This investment will translate to higher electricity supply security of this part of the capital.

RWE Stoen Operator makes sure the residents of Warsaw are provided with power supply. Its technical services constantly monitor the state of the electrical network. They also perform the necessary maintenance work to assure around the clock energy supply security for the city.

The operation of distribution system operators, including RWE Stoen Operator, is subject to regulation and mandatory submission of distributiontariffs to the Polish Energy Regulatory Office for approval.
