PUBLIC OPINION SURVEY: Poles prosumer about investments in renewable energy sources

The percentage of Poles interested about investments in renewable energy sources is significantly higher among people familiar with the term “prosumer” (67%), and among people informed about the adoption of a law on renewable energy (53%). The desire to invest in the near term is not significantly associated with higher incomes (the biggest interest is in multifamily homes, but rapidly increase with the declared interest in politics). As many as 44% of Poles interested in politics definitely declare their willingness to invest in the backyard microinstallation of renewable energy sources.

The largest group of potential Polish prosumers are people between the ages of 18 to 49 years, with secondary education, families with incomes in excess of 2500 zł and living in the capital region, western and central eastern Poland. Residents of rural areas, but also large cities (over 200,000 inhabitants).

Renewable energy equipment, in which most Poles would invest are solar collectors - qualified for 40% of respondents. One in six respondents have invested in small wind turbines, heat pumps and photovoltaic panels (PV). The greatest increase of interest in relation to the research of 2013 - by 5 percentage points was in the case of photovoltaics.

One-fourth of respondents who do not know the term "prosumer" and the law, it is difficult to say in what devices, if they had the opportunity, would like to invest. More often they pointed to investing in these types of installations, which make it possible to save heat than electricity.

The study aimed to analyze public opinion on the use of renewable energy sources (RES) in Poland, in the context of passed this year the Law on RES and a program to encourage the purchase of RES installations - Prosumer. Realized under the project "Agricultural farms and smart grids integrated renewable energy sources OZERISE" co-financed by the LIFE + Programme and the National Fund in the framework of the project LIFE11 ENV / PL / 444 commissioned by the Institute for Renewable Energy by TNS Poland on 03.27.2015 - 01.04.2015 omnibus test method, of an interview face-to-face (CAPI).

 

Implementation of the project

Implementation of the project – OZERISE – Agricultural farms and smart grids integrated renewable energy sources

OZERISE project is aimed to practical help in the selection of small-scale renewable energy sources on farms and their groups / co-operatives energy.  In the 10 farms that were selected for the project, installed electricity meters.

Adjusting the internal electrical installations on the farms to measure (and future installation microinstallations RES)

In addition, on the farm were installed  monitoring devices of wind power and insolation.

Installation of meteorological measuring mast to assess local renewable energy resources on farm

 

Based on the measurements of power consumption and meteorological conditions, prepared web application (calculator), which allows to chose hybrid systems of all kinds of microinstallations of renewable energy sources taking into account the consumptions profiles of electricity and heat for production purposes and living for each of the farms. It is also designed an energy management system in prosument farm.

Currently, research in the project OZERISE are in the process of analysis and develop results. The results enable to determine the relationship between dynamic energy needs and possibilities of their coverage by microinstallation  of renewable sources, which can be used on a farm with certain profiles the energy needs, technical conditions and location. 

The results of monitoring of electricity consumption in farms participating in the project OZERISE

An active electricity consumption in the first quarter of 01.08 – 30.11.2013 by farms participating in the project OZERISE included in the range between 5 000 and 22 000 kWh, while consumption of energy on living in all households contained at a constant level between 1 400 and 4 600 kWh.

Varied energy consumption results from the various energy intensity and scale manufacturing processes occurring in individual farms (and in the case of domestic purposes – from the number of household members). The largest energy consumption was notice in orchard farm (about 20 000 kWh).

Figure 1 shows the variation in energy consumption depending on the farm participating in the project.

Individual groups of energy consumers, which can be either a single device (eg. grinder, feed mixer, drying) and a group of devices working in one place (eg. cowshed, piggeries, house) are characterized by diversified intensity of electricity consumption. Also in this case, energy consumption depend on production scale. The largest energy consumption was observed in the piggery (165 dairy and beef cattle). Also, high energy consumption was characterized by a dryer, located in farms with large acreage crops (143 and 370 ha). Other manufacturing processes are shown in Figure 2.

The following diagram shows the hourly active energy consumption for selected receivers of energy.

There are two general reasons occurrence high variability in electricity consumption during the day. First one is the biological rhythm occurring at the farm (eg. milking dairy cattle in times of morning and afternoon or increased households activity in the mornings and evenings). The second reason is adjustment of working rhythm of the device to the electricity tariff structure (eg. grinder is active when a cheaper fare – in the afternoon).
In Figure 4 shows the seasonal electricity consumption for selected energy receivers.

Cold stores and dryers most intensively working in August and October, because in this month’s farmers must store fruits (orchard activities) and dry cereals after harvest. The seasonal variability in this case results from the nature of the producting processes.
