Concept of Conducting a Spatial Analysis of Heat Consumptionand Supply in the City Of Maribor
KOMUNALNA ENERGETIKA / POWER ENGINERING, 9
Sustainable heating and cooling solutions are based on modern technologies and increasing integration of various sectors of energy consumption and energy production – buildings, industry, electricity generation, and transport. District heating and cooling systems enable integration of various sectors, thus allowing for efficient management of all available energy sources and sinks. When planning energy management in a local community, such solutions require a systemic approach based on thorough spatial analysis of the current state and future development. The paper introduces the concept of conducting a spatial analysis of heat consumption and supply by using geographic information system tools of the City of Maribor.

PLANNING NEW RES ENERGY FACILITY OF ENERGETIKA MARIBOR BASED ON HIGH EFFICIENT HEAT AND ELECTRICITY PRODUCTION
KOMUNALNA ENERGETIKA / POWER ENGINERING, 9
Advanced heat production center, based on high efficient heat production, which would consist of a set of production and combined heat and power systems (heat and electricity), will provide for the region's largest district heating system additional quota of heat generated from high-efficiency systems and renewable energy sources.
The purpose of the center is to provide an optimized - real time heat production from renewable energy sources and combined heat and power production in line with real and momentary heat consumption of the system.
Advanced center will include:
• high performance, low-emission biomass boiler – 5 MW,
• combined heat and power production system powered by natural gas – 2.3 MWe
• high temperature heat pumps for the utilization of low temperature energy flows – 0.84 MW and
• public learning center on biomass energy utilization and advanced energy systems for efficient use of energy.

DESIGN AND OPERATION OF FIRST SLOVENIAN HEATING PLANT TO THE ENERGY-RICH FRACTION WASTE
KOMUNALNA ENERGETIKA / POWER ENGINERING, 33
Each year modern society produces more waste. Domestic habits and economic standard places us next to other developed countries thus statistically taken every person produces around a kilogram of waste per day. Taking into account the average heating value of waste this equals around a quarter of liter of heating oil or almost one-hundred liters per year. This energy potential is presently deposited in landfills across the country, causing shortage of deposition space, emission of green-house gases and production of polluted leaching water.
The utilization of this semi-renewable national energy source represents great challenge of the present time. Waste- to – energy means utilization of domestic energy source and greater import independence. The utilization of this energy is only possible with district energy systems. Our country has committed itself to utilize by the year 2020 25% of total consumed energy from renewable sources. The energy of waste can contribute to fulfil this commitment.
This paper is going to present a modern integral waste management system in Celje region and utilization of energy rich waste fraction after mechanical and biological treatment. The Celje heating plant is in operation for five years and it utilizes combustible fractions of the waste and produces power (electric energy) and hot water. The latter is distributed to the citizens of Celje over the existing district heating system
