July, 19th, “EKOLTAVA” team and journalists visit Horishni Plavni city council, invited by Oleksandr Chupryna, the mayor’s first deputy.
We were announced to see the progress in energy saving here, to hear about money profits and the experience gained while implementing and using uprated sets.
It should be admitted that the tour was full of content and a representative one: 4 spots, that is utility enterprises “Mis’ksvitlo”, “Teploenerho”, local urban water supply and dwelling zones.
The concentrating complex has decontamination buildings, which are thermal sets in fact. Our media squad had a talk with Oleksiy Haydabura, the manufacturing director of water supply enterprise in Horishni Plavni. He shed some light on purification plants functions, for instance, decontaminating water which later becomes a source of heat, that is, used iteratively.
“We have 12 to 16 thousand cubic metres of sewage daily, depending on the weather. Thus, we supply the city with 14 to 15 thousand cubic metres of purified water.
In 2008 a resolution was adopted to build the most economical and energy effective possible set which would supply the decontamination buildings with heat and hot water for minimal expenditures. And so, heat pumps were launched in 2016. As a result, we refused autonomous electrical heat completely.” – states Oleksiy.
The prime cost of a gigacalorie these pumps produce is 770 UAH. On the average, this is twice less comparing to natural gas or autonomous heaters. The initial temperature of sewage is 9 to 19 Celsius, purified water is 40 to 60 Celsius.
Yevhen Romas’, acting boss of sewage lines workshop КП ВУВКГ, speaked about heating pumps in more details.
“The pump conveys purified sewage to the exchanger, the heat taken up by glycol mixture. The mixture transfers heat to heating pump and then to the water circulating inside the urban heating system.”
Before the heating pumps installed, water was heated with electrical boilers. Now the expenses are 35% lower.
Since 2015, UE “Mis’ksvitlo” cooperating with department of communal services household, of Horishni Plavni city council have initiated the replacing of sodium light bulbs street lights with autonomous LED lanterns. The modernization have been completed before the end of 2016 with 1114 lighting units replaced.
LED bulbs power is 30 and 60 W. Sodium bulbs power is 150 W.
Vasyl’ Mykhaylyk, UE “Mis’ksvitlo” chief, reflects on the profits:
“Lighting expenditures were 1 470 000 UAH yearly with exploiting spendings in addition. LED-lighting results in 347 000 UAH per year. These new lanterns are self-serviced, autonomous and hard to be damaged intentionally. Using special software one can remotely regulate the lighting time according to duration of daylight hours”
The experience of implementing energy saving measures by condominiums of Horishni Plavni proved to be a piece of interest too. Dwellers of a multifamily house which belongs to Rubin 18 condominium are the participants of international project “Community-oriented local development” run by EU/DPUN and launched since 2015 in Horishni Plavni city council. The project supports the following leads in condominiums: energy saving and energy efficiency, modernization of plumbing and sewer, start for wastes salvaging.
“Financing the project of implementing energy saving in condominiums goes like this: 50 % are given by EU and UN, 45 % are covered by municipal budget, 5 % are condominium’s inner money” – comments Nataliya Ruban, chief specialist, section of improvement and housing, department of communal services household.
Head of board, condominium Rubin 18 – Roman Dubets’kyj:
“We started from putting everything in order, then we replaced all the plumbing and heating pipes, set the separated heating post (SHP) with function of weather-based regulation and solar boards for lighting public areas. This will help us to become independent from network electricity. Solar boards capacity is 600 W. We also installed new windows in all the four flat sections”
To fulfill the project, four multifamily houses were selected out of sixteen applied.
The fourth spot of our tour is worth special attention.
Since May 2015 there is a solid-propellant boiler-room functioning at UE “Teploenerho”. Its power is 1,64 MW, it supplies with hot water district 15 of Horishni Plavni – that is, 24 multifamily houses. Two solid-fuel boilers of capacity 820 kW each can consume several kinds of fuel: chips or firewood with peat and agricultural pellets as well.
Now only firewood and chips are in use as the most appropriate and obtainable fuel. The staff numbers only four people. An enterprise like this has a handler to convey fuel to boiler-house with hoisting capacity 600 kg and an electrical woodchopper, so the process runs rather automatically.
Constructing of this boiler-house was financed from local and state budget, local enterprises also contributed.
Pavlo Snizhko, chief engineer, UE “Teploenerho” states that this boiler-house spares up to a million cubic metres of natural gas yearly.
This press tour clearly shows that serious shiftings lead to more substantial results. Our CSO continues to display the experience of Poltava region in energy saving and implementing renewable energy sources. We want to inspire region dwellers to invest money into sustainable energy development, that is, into the future of our country.
