The new service offers a rational solution to deal with challenges such as rising fossil fuel and emission allowance prices, the impending extension of the EU ETS to small sources, the stability of natural gas supply, the declining availability of biomass, the requirements of new directives on the efficiency of heat production and the use of RES, as well as the need to ensure affordable energy and a healthy living environment for the inhabitants of towns and cities.
Green heating works with a hybrid system of heat and electricity production using the mutual advantages of different sources. ORGREZ experts design the system according to the needs and character of the site, combining conventional gas, biomass or waste sources with modern RES. “We maximise the utility of the photovoltaic plant in combination with a cascade of heat pumps and electric boilers. We supplement the system with hot water storage or batteries to cover the time discrepancy between electricity production and heat consumption,” explains Jan Krišpín, CEO of ORGREZ. A key element of the system is an automated control system that will enable the purchase of missing electricity for heat generation at times of daily price minima and ensure the operation of the most advantageous combination of sources at any given time. All of this is managed through the cloud, which the company operates for customers.
Benefits not only for the environment, but also price stability and increased safety
The ecological benefit of the hybrid system lies in the possibility of combining current sources with renewable energy sources with a high emphasis on short-term heat storage, which allows the system to significantly reduce the consumption of fossil fuels. “By linking the system to the community energy system, it also enables the direct use of surplus energy from municipal renewable sources that could otherwise be thwarted,” adds Jan Hanus, Environmental Project Manager at ORGREZ ECO.
From an economic point of view, the system stabilises, improves or maintains the price of heat at a comparable level and, in addition, when linked to other areas (e.g. public charging of electric vehicles or consumption of urban buildings), can significantly reduce the total cost of electricity for these operations.
On the operational benefits, Jan Hanus adds: “The system contributes significantly to the diversification of resources, i.e. the possibility of choosing the optimal mix of currently operated resources according to current market prices. In addition, the system emphasises the maintenance of sufficient available power and capacity of backup sources to ensure safe heat supply.”
