Abstract
The utilization of renewable energy sources spread with stormy speed on the world there-
fore more and more municipalities propose to provide their energy demand from renewable
sources.
The fossil fuels represent a significant proportion in Hungarian energy balance and the ma-
jority of these is import energy.
The proportion of renewable energy sources must be increased to narrow the energy depen-
dence and the energy cost of municipalities, to increase the energy security and to consider
the aspects of environment.
The interest of Hungary is to increase the proportion of renewable energy sources in en-
ergy supply.
In order to this, the government created the small, household size power plant category
in the Electricity law. This power plants should be not greater than 50 kW’s performance.
In this category, electricity can be produced from renewable and fossil sources.
Since the government introduced the small, household size power plant category the in-
stalled capacity grew quickly in the last seven years. The whole capacity was only 0.51 MW
altogether at the end of 2008 but it has already approached 129 MW’s at the end of 2015. The
whole capacity was increased the multiple of the previous year amount every year between
2008 and 2015 and further dinamic capacity expansion will be expected. The 99.5% of in-
stalled capacity comes from renewable energy source and the 99.0% derives from solar energy.
This capacity increase is remarkable despite the fact that the price paid for excess pro-
duction is lower the full end consumer price. If the input electricity volume is bigger the
offtaken electricity volume in the accounting period then at a given connection point selling
electricity trader or universal service bound to pay to the owner operator of the small, house-
hold size power plant lower price than the end consumer price. So only electricity saving
and environmental awareness generated the capacity growth in Hungary.
The capacities and the produced electricity can be displayed as data on municipality level,

too. The purpose of the researches is to determine how the built capacity of the small,
household size power plant category can participate in the electricity supply of Hungarian
municipalities.
So how many percentages of electricity demand can this electricity power gratify in the
municipalities? Based on this, a municipalities ranking can be made which shows the level of
sufficiency in production of renewable energy and give the possibility for planning the power
shift. To what extent can we build upon on this power plant category that Hungary can
comply its objective value.
The investment accomplishment of the residential, institutional and company segment was
motivated by merely the energy saving while using renewable energy – primarily solar energy.
Based on by accomplishments it can be assumed that production aid of energy production
could help Hungary’s renewable energy goals.
The accomplishments seem to disprove those hypotesis according to which a municipality can
not satisfy its electricity demand from renewable energy source. The data provided shows
that the electricity demand of municipalities can be provided in 100% by villages and this is
not impossible by small or big cities.
