08.10.2012 The brightest among the thrifty

Yekaterinburg is the leader in the rating of the most energy efficient cities of Russia. Back in 2009, the city had entire streets illuminated by LED lights.
When in 2009, a new lighting system with LED lights was installed on five streets of Yekaterinburg, the power consumption in this part of the city was reduced by almost one third. Since each lamp can be controlled separately and not only from the control room, but also using a portable point, the maintenance costs were considerably reduced. Troubleshooting and quality repairs in the traditional cascade system required the switching on of several streets (five- seven streets), while the new system allows for spot searching - to locate and identify faults.
Following this experiment, a long-term city target program was launched; its first stage was completed by the end of 2011. The development of energy balance capacities of Yekaterinburg was carried out as part of the program, and the employees of public utilities studied the characteristics of energy-efficient technologies. The program also provided for energy audit of the city’s infrastructure, and modernization of units of commercial energy accounting.
The project was proven as being profitable. Therefore, it is being significantly expanded for the period 2012-2014, and its implementation involves private enterprises.
Made jointly with Germany
The Russian-German project "Yekaterinburg – the Energy Efficient City" is being implemented in Yekaterinburg since 2010, as part of state program of energy conservation and energy efficiency. The Siemens Company, one of its key members, previously undertook a comprehensive analysis of energy efficiency of the city. The decision in this respect was taken in October 2008 on the initiative of Russian President Dmitry Medvedev and German Chancellor Angela Merkel.
According to the evaluation of the company, the introduction of technologies that are used in the U.S.A. and Europe will allow Yekaterinburg to save approximately 34 billion kilowatt-hours per year (44% of primary energy) by 2020. "Given the fuels consumed by Yekaterinburg when using conventional technologies, this corresponds to a reduction of consumption by 2 billion cubic meters of gas per year," said the press service of Siemens.
The total investments into urban infrastructure will come to only about € 3.6 billion. In most cases, the payback period will not exceed four years.
The program provides for the implementation of several schemes and solutions, such as individual heating systems, water-saving technologies, energy saving lamps, and triple-glazed windows. With regard to energy facilities, Siemens proposed to use cogeneration (combined production of electric and thermal energy) in the heating plants and boilers, and improved the insulation of heating utilities.
"Inadequate quality of heating networks is a major problem. Heat loss in transit is between 30% and 50%, the problem is worsened by the considerable length of hot water systems in Yekaterinburg – 3,500 km," informs the press service of the concern. Better heat insulation will reduce the maintenance costs of heating mains, as well as minimize accidents.
Today, Siemens’ solutions are already implemented in the terminals of Koltsovo Airport, the residence of the presidential envoy in the Urals Federal District, the Hotel Hyatt Regency Yekaterinburg, Palladium Business Center, and the Atrium Palace Hotel.
Energy efficiency of the Ural capital was also improved by the German company BASF, which worked in close cooperation to modernize the utilities and equipment in the Akademichesky District. As a result of this cooperation, "in 2010-2011, heat consumption in the apartment houses was reduced by 30-35% of the average city level (0.0224 instead of 0.033 Gcal/sq. m. per month), the cost of electricity for lighting public places was reduced ten-fold," announced the press service of the Ministry of Energy of the Sverdlovsk Oblast.
After the total modernization of district utilities, heat losses in the Akademichesky do not exceed 2.63%, electricity losses - 3.92%. As a result, payments for utility services in the district are 25% less than the average city indicators.
The energy review, which was conducted in the buildings of the Akademichesky District, has allowed assigning these premises a ‘Class C’ (normal) energy efficiency rating. In addition, a pilot ‘Class B++’ building was designed and built.
Now the Akademichesky has a joint dispatch center to collect and process information on energy consumption, which helps monitor the application of energy efficient technologies.
In July 2012, the Russian-German Energy Agency Rudea signed an agreement with the Ministry of Energy, the Government of the Sverdlovsk Oblast, the administration of Yekaterinburg and the Integrated Energy Systems Company (IES CJSC) to develop cooperation in the field of energy efficiency in the Sverdlovsk Oblast.
"This agreement covers the consumption of energy resources in the heat supply system of Yekaterinburg. For this purpose, there will be developed a program to improve the energy efficiency of the heating systems in Yekaterinburg for the period of 2012-2027," the press-service reports.
The Rudea Agency has already conducted an energy audit in the production departments of Uralkhimmash OJSC. “The indexes of energy efficiency of companies and the heating system of Khimmash District have been analyzed, as well as the potential for energy conservation and energy efficiency,” says the press service of Rudea.
The cost of the technical and organizational measures for energy conservation and energy efficiency will amount to about 1.3 billion rubles, while the average payback period will be seven years.
The regional government claims that under the program "Yekaterinburg – the Energy Efficient City", by 2014, the city intends to realize energy savings of 21.37 billion rubles.
According to the estimates of Siemens, the introduction of technologies that are used in Europe and the U.S.A. will allow Yekaterinburg to save approximately 34 billion kWh per year by 2014.
After the introduction of energy efficient technologies in the Akademichesky District of Yekaterinburg, the utility bills of the residents were reduced by 25%.
