In 2008 the acquisition of the OPM 2 SR heating plant as a subsidiary of A.EN. Slovensko, took place. The company is based in Nitra and its role is to operate the Central Heat Generating Source (CHGS) in Chrenová.
The CHGS consists of 4 boilers with the total installed output of 34.36 MW, thanks to which OPM 2 SR, s.r.o. is capable of supplying heat and hot service water to the entire urban district of Chrenová. The total annual volume of the produced heat constitutes approximately 170,000 GJ. All the operated devices are subject to regular inspections which guarantee their functionality, reliability and a high level of annual availability.
OPM 2 SR, s.r.o. has set itself clear pririties:
It burns local natural gas which is extracted in the vicinity of 11.5 kms from the CHGS, by which it partially contributes to a lower reliance of the Slovak Republic on natural gas imports from abroad.
The operation achieves an average annual effectiveness in heat production above the set limit of effectiveness thanks to a regular maintenance carried out by our qualified staff.
The burning of natural gas for heat production produces a smaller amount of CO2 greenhouse gas in comparison with the burning of coal as a result of a smaller emission factor, and, practically, no solid pollutants such as fly ash are produced.
On the basis of the quality standards assessment, it reaches 100% reliability and quality regarding heat supplies to consumers.
At present, OPM 2 SR, is trying to launch heat production in cooperation with the Nitra Municipal Power Plant, Inc., which operates the Cogeneration Power Plant with combined highefficiency electricity and heat production. This cooperation should lead to a decrease in operating costs of the primary energy sources and also to a decrease in the prices of heat for consumers.
In 2013 A.EN. Group expanded due to the acquisition of a business share in the company TEPLICO s.r.o., in which the Town of Turčianske Teplice is a business partner. Its activity involves the production of heat and hot water as well as residential and commercial property management in the Town of Turčianske Teplice. As much as 96% of Teplico’s income comes from the production and supplies of heat and hot water.
Up until the 1990s, Teplico was only engaged in residential and commercial property management for its only customer, the Town of Turčianske Teplice. Due to the general interest expressed by tenants regarding the sale of council flats to personal owners, in the last decade part of the town’s residential property was sold into personal ownership. In a majority of cases the sitting tenants became the new owners and united under Flat Owners Associations (FOAs). Owing to the previous long-term cooperation, FOAs decided that Teplico should continue to provide residential property management to them.
While in the 1990s at its production facilities Teplico produced approximately 14 GWh of heat per year, currently, it produces around 7 – 8 GWh per year. This is caused by the fact that, currently, 98% of consumers’ flats are insulated and heat adjusted. Simultaneously, the company modernized its heat generating sources in such a manner that today it produces heat not only in gas-fuelled hot water boilers, but also in condensing gas boilers. The company also operates a woodchip biomass--fuelled boilers with the installed heat output of 1.00 MWt, from which heat is supplied to consumers in the urban district of Horné Rakovce, using this method to produce ca. 50% of the total heat production from this source. At the same time, a technical and financial evaluation is being prepared for the replacement of gas-fuelled boilers with biomass-fuelled boilers in other boiler houses.
“Mestská elektráreň Nitra, a.s.” (the Nitra Municipal Power Plant, Inc.) operates two independent power plants: → The Nitra Cogeneration Power Plant → “BSP ČOV Nitra” (the Nitra Sewage Treatment Plant)
The Nitra project company “Mestská elektráreň Nitra, a.s.” (Nitra Municipal Power Plant, Inc.) with the 100% ownership interest of A.En. Slovensko s.r.o. was established in 2008 with the clear aim of constructing and subsequently operating combined high-efficiency electricity and heat generating sources.
The process of the realization of the large Nitra Cogeneration Power Plant project commenced in August 2014. The proposed site for the new energy source is situated in a built-up area of the City of Nitra, on the south-western outskirts of the urban district of Chrenová, on the existing site of the Nitra Central Heat Generating Source. The new source was constructed with the aim of supporting the Slovak transmission network and also of using waste heat generated by the equipment in order to heat service water in residential houses and public facilities located in the connected housing estates in Nitra.
Apart from the main project, in 2013 the Nitra Municipal Power Plant realized the Reconstruction of Energy and Gas Management at theSewage Treatment Plant project in Nitra – the installation of a cogeneration unit utilizing biogas as a fuel for the production of heat and electricity. The aim of the project consists in an effective utilization of energy of the entire amount of biogas produced as a byproduct of sewage treatment. Biogas will be burnt in the new cogeneration unit which will produce electricity and heat and, thereby, will utilize, to the maximum extent possible, the energy potential of biogas. The generated electricity and heat will be utilized directly on the production site, i.e. on the premises of the sewage treatment plant, which will enable to lower the operator’s costs.
The Nitra Municipal Power Plant as the main investor in the projects believes that by operating its power plants it will achieve a decrease in and stabilization of heat production costs for the inhabitants of the City of Nitra, it will support the stability of the transmission network within and in the vicinity of the city, and, by installing the best technologies available in this segment, it will contribute to the decrease in the amount of emissions and, consequently, to the protection of the environment.
Trnavská ekologická spoločnosť deals with production and distribution of heat, production and distribution of electricity produced by production equipment with total installed power until 1 MW from renewable resources, if it is production and distribution electricity to equipments, which uses biogas.
