The CHP unit produces the electric power to supply production processes and the heat in a form of hot or warm water or steam where needed in the production process. Cold water can also be produced. The cold produced in the cogeneration is significantly cheaper than that produced by conventional manner. Due to the constant and high consumption of heat and power during the year, the economic savings are high. In these industries, it is common for companies to have their own heat sources with over 20 MW of fuel input. The price of heat produced by the CHP unit does not change much even with the high price of allowances. This is due to the fact that the price of power produced by the CHP unit rises with the price of the allowance and then the revenue from it also rises eliminating significantly in doing so the impact of the allowance on the price of heat. In this case, the installation of CHP unit can eliminate the cost for emission allowances. In addition, the independence from external suppliers ensures the continuity of operation in the case of black-out.A properly designed CHP unit, even if companies do not have stable year-round heat consumption, brings customers significant savings even when the CHP unit runs for six to eight months during the colder seasons when the heat is needed to heat interiors and HDW. The price of heat produced by the CHP unit does not change much even with the high price of allowances. This is due to the fact that the price of power produced by the CHP unit rises with the price of the allowance and then the revenue from it also rises eliminating significantly in doing so the impact of the allowance on the price of heat. The economic savings in such a mode can be in the order of millions of crowns per year, depending on the size of the operation. Moreover, the savings are made up of several components, making them diversified and long-term. Especially in times when the energy prices are on the rise, the CHP unit pays for itself and eliminates the impact of rising costs on inputs.In the food production, there is a high consumption of process heat or steam. Both can be produced more cheaply on the CHP unit than with the conventional sources. Along with this, this production is also demanding in terms of power consumption and therefore CHP units represent a suitable way to reduce costs in these plants and at the same time reduce the cost of emission allowances for the sources with a fuel input higher than 20 MW. The price of heat produced by the CHP unit does not change much even with the high price of allowances. This is due to the fact that the price of power produced by the CHP unit rises with the price of the allowance and then the revenue from it also rises eliminating significantly in doing so the impact of the allowance on the price of heat. Cold water can also be produced. The cold produced in the cogeneration is significantly cheaper than that produced by conventional manner.Thanks to the animal waste generated by these plants, it is possible to produce biogas on site through the anaerobic digestion. The companies using biogas CHP units can thus ensure energy independence and they significantly improve the cost-effectiveness of their business. In addition, all energy is produced in an environmentally friendly way. In the Czech Republic, most biogas plants were commissioned eight or more years ago and nowadays they are faced with the need to renew CHP units that need overhaul or replacement after 50-60,000 operation hours. The CHP unit renewal is a part of our services and we have a good track record in this field.CHP units are also a suitable source of energy for CHS systems which have a long tradition in the Czech Republic, being an important part of our energy sector. Heat consumption here is usually significantly higher during the heating season. Large sources of thermal energy are now at a disadvantage due to high allowance prices and often find themselves on the edge of a fight for survival. Even when switching from coal to gas, they often face rising heat prices due to the rising allowance prices. But this is only the case if they install gas boilers instead of the combined heat and power production. The price of boiler heat is very sensitive to the rising allowance prices. Whereas the price of heat produced by the CHP unit does not change much even with the high allowance prices. This is due to the fact that the price of power produced by the CHP unit rises with the price of the allowance and then the revenue from it also rises eliminating significantly in doing so the impact of the allowance on the price of heat. This proves that the CHP unit is a suitable instrument for eliminating the negative effects of high allowance prices for companies and district heating plants. The beauty of this mechanism is that it has a kind of self-regulation (higher EUA price = higher revenue from EE sales = mitigation of EUA impacts). Moreover, this will soon be backed up by interesting returns for providing the flexibility, which will be a scarce commodity. Plain and simple, district heating plants and enterprises have a great chance to become the electric power producers and profit therefrom, or at least to mitigate the impacts of allowances.Accommodation facilities with a capacity of around 50 beds or more have generally a sufficient demand of the heat for heating in the heating season and, in contrast, they consume the cold for air conditioning in the summer, and there is a constant consumption of HDW all year round. The need for electric power is also relatively high, especially in larger accommodation facilities, and the CHP units can reduce the cost of this energy significantly for them. It is also an advantage in terms of balanced energy consumption when hotels have their own laundries, mangle rooms, wellness centers or restaurants.Facilities such as hospitals have a high consumption of heat from the electrical energy. Moreover, the need is relatively even throughout the day and year. In summer, some wards also need cooling in the form of air conditioning - this can be provided by installing the trigeneration, that is, the CHP unit connected to the absorption unit. In large hospitals, there are large thermal sources with a fuel input above 20 MW which belong to the EU ETS system. The CHP unit is a solution for the large hospitals that have their own source of heat. The price of heat produced by the CHP unit does not change much even with the high price of allowances. This is due to the fact that the price of power produced by the CHP unit rises with the price of the allowance and then the revenue from it also rises eliminating significantly in doing so the impact of the allowance on the price of heat. In hospitals, more than anywhere else, there is a need for the quality and uninterrupted power supply, which is why the advantage of the CHP unit, equipped with a synchronous generator that enables the generation of power in the island operation in the event of an energy black-out, is perhaps most applicable here.The need for power and heat is relatively stable throughout the year. Thermal energy is needed to heat the water in the swimming pool, in showers, to heat the premises, including saunas and whirlpools. The power is used for lighting, driving pumps and the services of non-technical character. These facilities are often subsidized by municipal coffers, so the CHP unit installation can help municipal budgets in particular, as well as all the other operators of these facilities. Properly designed CHP units can deliver significant savings.These types of buildings have a high power consumption all year round. At the same time, heating costs during the heating season and cooling costs outside this season are high. As a rule, the heating and cooling distribution systems are already in place, therefore only minimal costs for the modification of the premises are required in the case of the CHP unit installation. These factors make the commercial and administrative centers one of the most suitable locations for the CHP unit installation. By installing the CHP unit, these buildings gain a competitive edge thanks to the lowest possible energy costs and, as a result, they become more attractive to tenants.
