What are energy-intensive companies and what are their obligations?

Technically, “energy intensive companies” are those companies that have an energy consumption of 1GWh or more per year.
The costs of primary energy and therefore of electricity in Italy are the highest in Europe and have risen further in the last period: an unforeseeable and unimaginable fact!
The technology in the field of co and trigenerative applications, offers a strong support and help, collaborating to the achievement of objectives not only of economic savings but also of decreasing emissions of harmful gases into the atmosphere.
A field of action in which IBT Group is a leader. In fact, the company is dedicated to the development of high-efficiency solutions, with specific expertise in cogeneration and trigeneration applications for any type of industry, thanks to partnerships with Capstone Green Energy and Century Corporation. Here’s what to know about it!

Energy-intensive companies?

Energy-intensive companies are characterized by high consumption of electricity. In Italy, there are about 3,100 companies, they are mainly large and distributed mainly in the manufacturing sector of metalworking, paper industry and also food. The CSEA, (Cassa Servizi Energetici e Ambientali) publishes annually the complete list of them, classified according to the consumption of electricity and the consequent impact of energy costs on their annual budget. Due to their volume of business they are considered strategic, and for this reason they are allowed to have recourse to specific facilities decided on the basis of government decrees. These forms of protection, which are widespread in many European countries, are represented in Italy in the form of discounts on system charges paid in the bill. In fact, they are a contribution by the State so that they do not lose their competitive advantage at international level. Although appreciable, these forms of protection, discounts on the bill, are neither sufficient nor adequate to meet the current, and even less so, future obligations of the companies to achieve the essential criteria of climate balance.
It is now indisputable that in order to meet these objectives it is essential to save on energy consumption, that is, with the support of technological innovation to implement all the necessary actions to meet their energy needs efficiently and at the same time protecting the environment.
These companies have a clear understanding of the concept of energy efficiency, benefiting from a policy of savings in production that is directly linked to the policy of environmental sustainability. A paradigm that is now essential in the field of industrial production.

Energy-intensive companies and the Energy Diagnosis obligation

Energy-intensive businesses are obliged to carry out an Energy Diagnosis (i.e., an assessment of the energy efficiency and consumption of a business in order to identify possible improvements) every four years. Legislative Decree 73/2020, published in the Official Gazette on 14/07/2020, introduced the obligation for energy-intensive companies to implement at least one of the energy efficiency measures identified in the Energy Diagnosis in the period between one diagnosis and the next. These allow to reduce energy consumption, evaluate the energy performance, save on energy bills and protect the environment, all without minimally affecting the performance of a system. In this regard, IBT Group proposes energy efficiency projects that exploit the most modern technologies, to help companies to be more competitive on the market in total respect of the planet, also creating customized solutions designed to contain the consumption of primary energy and reduce the energy bill.

Microgrid: integrated charging stations for electric vehicles in Italy

Capstone Green Energy, a leading Californian company and the world’s only manufacturer of energy systems that reduce carbon emissions through the use of gas turbines with oil-free technology, together with IBT Connectring Energies, exclusive partner in Italy and Greece, will provide three C65 microturbines to build an innovative MICROGRID in Italy with integrated charging stations for electric vehicles (EVs). The collaboration of IBT and S4E, an important Italian ESCO, has enabled the development of this microgrid solution in CCHP (Combined Cooling Heat and Power), one of the first examples of its kind in Italy.
The project is scheduled to start in March 2022, and is expected to dramatically reduce on-site greenhouse gas emissions to the tune of over 1,000 tons per year. Here’s what to know about this important news!

THE NEW INTEGRATED CHARGING STATIONS FOR ELECTRIC VEHICLES IN ITALY

In the energy field, the term MICROGRID indicates a small, self-sufficient local network for the generation of electrical energy that can support and integrate the public electricity network. The increasingly widespread use of electric vehicles has contributed to a strong expansion of this technology. Currently in Italy there are about 17,000 recharging points for vehicles, clearly already insufficient for the needs.
Capstone Green Energy’s Gas Turbines perfectly meet the different requirements of a Microgrid network.
In fact it is essential that the recharge mode is fast, simple and safe. Capstone gas microturbines allow the creation of flexible Microgrids and produce directly in direct current the energy needed to recharge vehicle batteries. They can operate in “stand alone” and do not depend on the public grid, contribute to energy efficiency by integrating if necessary to other types of power generators such as photovoltaic, hydrogen fuel cells, as well as battery storage systems. Finally, they are known to have very low gas emissions into the atmosphere thanks to oil-free technology.
The scenario for the next 5-10 years envisages millions of electric vehicles.
With this application IBT and S4E System are contributing to satisfy and support with this innovative technology the requests that are made by our new and reborn Company.

THE STRUCTURE OF THE PROJECT

“The development of this innovative CCHP microgrid solution with integrated EV charging reflects the vision of our customers who are increasingly focused on greener and sustainable solutions,” said Darren Jamison, President and CEO of Capstone Green Energy. This cutting-edge application presented by Capstone Green Energy, IBT Group and S4E System is based on 3 Capstone C65 microturbines and allows the production of cooling, heat and energy using low-pressure natural gas to provide electricity and thermal energy to the end user. S4E, the owner of the plant, will manage and maintain the plant provided, making it possible for the end user to remain focused on its core business activities. Capstone’s clean turbine technology is a key component in the integrated EV solution due to its modulation capability, high overall efficiency and ultra-low emissions. the complete facility makes available a reliable and flexible on-site solution with the ability to charge EVs independently without relying on the local distribution network.

IBT GROUP PARTNERS

“The long-term partnership between IBT and S4E was strategic for this project. IBT and S4E’s extensive technological and commercial expertise were instrumental in the acquisition of this complex green energy project,” said Ilario Vigani, president of IBT Group.
S4E is a Certified Energy Service Company, consisting of a team of engineers specialized in energy efficiency projects in the industrial, civil and advanced tertiary sectors in general, while Capstone Green Energy is responsible for the construction of cogeneration and trigeneration plants that provide a significant reduction in energy bills, low maintenance and zero emissions by means of oil-free technology, which refers to the complete absence of lubricating oil inside the turbines through the use of air bearings that can support the turbine shaft in rotation without mechanical contact.

Turbogas plants and power stations: all you need to know

We often hear about turbogas power plants, but what exactly do they consist of? And what advantages do they bring? Here’s everything you need to know about them.

What is a turbogas plant?

Turbogas power plants use a primary energy source, usually methane gas, biogas, diesel oil but not only, to produce electricity through a gas turbine. These turbines, which replace the traditional and obsolete internal combustion engine, are made up of the following macro-components that operate according to the Brayton-Joule cycle:

  • Compressor: Combustion air is drawn in and compressed.
  • Combustion chamber: Combustion air and fuel react chemically, producing heat (combustion).
  • Turbine: the combustion fumes at high pressure and temperature expand in the turbine making it rotate and thus producing mechanical energy.
  • Alternator: Converts mechanical energy into electrical energy.
  • Regenerator: recovers part of the heat from the exhaust fumes to pre-heat the combustion air before entering the combustion chamber, increasing the electrical efficiency of the machine.

Gas turbines

As described above, gas turbines convert the chemical energy of the fuel into electricity through the generator, recovering the thermal energy also from the exhaust gases: all this is done with the gas turbines Capstone Green Energy by IBT Group, which is the exclusive distributor for the Italian market. These turbines originating from the aeronautical sector, have only one moving part, namely the shaft on which are keyed turbine, compressor and generator. The latter rotating on air bearings without mechanical contact and therefore without friction is “stress-free” as cushioned by a specially designed support structure that ensures durability and functionality of the mechanical parts. Capstone’s gas turbines have many advantages, such as the modulation of the electrical load from 0 to 100%, the reduced emission of pollutants into the atmosphere (NOx < 19mg/Nmc and CO < 50 mg/Nmc, the lowest available today), low vibration and noise emissions and low maintenance costs. By recovering the heat contained in the exhaust gases of the turbines it is possible to obtain other thermal vectors, such as hot air, steam, superheated water, hot water and – through an absorber – chilled and frozen water. This increase in energy production does not correspond to an increase in fuel consumption, thus ensuring high energy efficiency.

Turbogas efficiency

The thermodynamic cycle of turbogases is simple and efficient. Thanks to the combustion in excess of air and to the simplicity of construction, it is perfectly suited to co- and trigenerative applications. In fact, in the industrial sector in co- and trigenerative set-up, despite the fact that there is an increasing demand for custom plants that meet the needs of production processes, the overall efficiency is higher than 85%.

District heating technology: how it works and what benefits it offers

We often hear about district heating, but what exactly does that mean? And what advantages does it bring? We at IBT Group are able to meet this need as well, thanks to our high-efficiency cogeneration plants that exploit the patented oil-free technology of our partner Capstone Green Energy. Here’s what to know about it!

What does district heating consist of

The term “district heating” refers to a form of heating that consists of the distribution of hot, superheated water or steam generated by large cogeneration plants by means of pipeline networks to individual residential or commercial units – all managed remotely. In this way, the water arrives at the buildings for both heating and cooling purposes and then returns to the power station at either a lower or higher temperature. To power a district heating plant, different types of fuel can be used. District heating technology enables very high overall efficiency levels to be achieved, which translates into savings in terms of economics, logistics and the environment.

What is the purpose of district heating?

Thanks to district heating, it is possible to remotely distribute heat for both heating and cooling of buildings used for housing or commercial activities. In other words, it is a complete system of production and distribution of highly efficient heat that uses different energy sources, renewable and non-renewable. This offers numerous advantages from several points of view, such as:

  • Stricter and more frequent control of the fumes emitted from the chimneys of cogeneration plants than that of plants belonging to condominiums or individual houses;
  • The choice of the fuel used is based not only on the basis of economic convenience and market availability, but also on the availability of resources in the area of reference, whether renewable or not;
  • The limited need for maintenance;
  • More efficient use of primary energy;
  • Increased energy security, due to the possibility of exploiting several energy sources simultaneously at the local level;
  • Reduced transport and maintenance costs;
  • Reduced emissions of CO2 and other pollutants, such as NOx, CO and particulate matter.

How does the district heating network work?

A district heating plant is designed and constructed on the basis of a consumer needs analysis (estimated or actual) and the possible distribution route. This can be direct or indirect: in the first case, a single hydraulic circuit connects the plant with the user’s heating body while in the second case, there are two or more separate circuits connected through special heat exchangers. The water is then transported through a network of pre-insulated pipes to the connected buildings. Here by means of sub-stations the heat is transferred to the building system, allowing both, the heating of the rooms and use of hot water. Once the heat has been transferred, the water returns to the power station to restart its cycle. In most cases, the heat production plant also produces electrical energy at the same time, thanks to cogeneration. Cogeneration is synonymous with energy efficiency: using a single primary energy carrier, both electrical and thermal energy are produced with very low harmful emissions at low costs and with respect for the surrounding environment. An example is the installation to meet the needs of the new district heating system of Cervinia carried out by IBT Group: here it was applied the cogeneration system with Capstone C1000 Turbine in the “Dual Mode” version, an additional plus that allows in addition to the normal operation in parallel to the network, also the functionality in isolation in case of blackout. The result is the combined production of 1000kWel and hot water at 105°C obtained by exploiting the exhaust gases leaving the turbine.

Industrial trigeneration to improve energy efficiency

The term “Trigeneration” refers to the combined production of electrical energy, heat and chilled water; the latter is usually used in air conditioning systems or industrial processes and is produced by means of absorption refrigerators. It is therefore an extension of the possibilities offered by cogeneration, which is indicated by the English acronym CCHP (Combined Cooling, Heating and Power). We at the IBT Group, together with our renowned partners Capstone Green Energy and Century Corporation, offer tailor-made energy efficiency solutions for various sectors: here is what you need to know about industrial trigeneration.

Industrial trigeneration systems

Cogeneration involves the simultaneous production of electrical and thermal energy using a single primary energy source, with savings of over 30% on average.
In civil and industrial users, summer air conditioning requires cooling energy to meet the needs of users.
It is in these cases that the trigenerative set-up is applied, which extends cogeneration plant with special absorption chillers for the production of chilled water. This makes it possible to exploit this type of plant in any period, and is particularly useful in industrial sectors that require cooling systems, such as Food & Beverage.

Cogeneration and Trigeneration for further improvement of energy efficiency

A trigeneration system involves a higher overall efficiency thanks to a greater exploitation of the power generated by the fuel, which is used both to produce electricity and as a source of heating, and as energy to power absorption refrigerators for refrigeration. Both types of plants are offered by IBT Group, which combines Capstone Green Energy’s patented oil-free technology (of aeronautical origin), i.e. the complete absence of lubricating oil inside the turbines thanks to the use of air bearings capable of supporting the turbine shaft in rotation without mechanical contact, with Century Corporation’s absorption refrigerators, which allow the production of cooling energy for summer air conditioning and/or for production processes.
These plants have numerous advantages in economic, environmental and structural terms including:

  • Lowest emissions of all CHP systems with NOx < 19mg/Nmc and CO < 50 mg/Nmc, therefore respectful of the environment
  • The reduction of fuel consumption, thanks to the further improvement of the overall efficiency of the plant, which translates into an economic saving
  • The complete modulability from 0 to 100% of electrical and thermal power, following the user’s request – Overall yield > 85% with production of valuable carriers
  • Ease of management and low maintenance costs
  • No vibrations and low noise emissions
  • The reliability of having 8,600 continuous hours/year guaranteed

Applications and sectors

As IBT Group we are guaranteeing to meet the specific needs of our customers basing on the most advanced technologies to support the competitive increase of your company in total respect of the planet.
This application is intended for large civil users and for all those industrial realities that require high-efficiency trigeneration plants: for example, in the Food & Beverage sector, where industries need valuable thermal vectors, such as saturated steam, superheated water and glycol water at sub-zero temperature, for the production process but also in the Chemical & Industrial sectors, for Hotel & Wellness sites, Hospitals and Pharmaceutical sectors. The possibilities of industrial trigeneration are really huge, they increase the competitiveness of your company and keep the resprect for the planet always in the foreground.

Decarbonisation: what it means, what are the benefits for the future

Decarbonization is a safe and effective solution to improve the companies environment to ensure the ecological balance of our planet. This is necessity that today more than ever must be a shared commitment. The IBT Group makes its contribution through the offers of cogeneration and trigeneration solutions. Here’s what to know about it and what are the advantages!

The decarbonisation process: what it means

“Decarbonisation” refers to the process of reducing the carbon-hydrogen ratio in energy sources. In business, this term is used to refer to policies to reduce CO2 emissions in order to drastically reduce emissions into the atmosphere. This happens, for example, when a coal- or oil-fired power plant is converted into a new one that uses renewable energy sources. Using those low carbon energy sources contributes strongly to reduce as much as possible the current greenhouse gas emissions into the atmosphere, a key element in the fight against climate change. To achieve this result, you can opt for different ways, such as choosing to use fossil fuels with a lower carbon content, replace where possible fossil fuels with renewable ones or opt for energy efficiency solutions, such as those proposed by IBT Group, which use the latest technologies to help companies to be more competitive in the market, in total respect for the planet. Thanks to the cogeneration and trigeneration plants, which exploit the patented oil-free technology of aeronautical origin of Capstone Green Energy and the absorption chillers of Century Corporation, it is possible to contain the consumption of primary energy and reduce the cost of the energy bill. This creates further significant advantages in terms of environmental sustainability: suffice it to say that the systems installed by IBT Group have the lowest emissions of all CHP systems, with NOx < 19mg/Nmc and CO < 50 mg/Nmc, well below the legal limits.

What is decarbonisation for?

Decarbonisation is a useful process to environmental impact, making the best use of available resources and, above all, opting for the least polluting ones possible. These choices lead, over time, to a reduction in the ratio between the emissions of a single country and the amount of energy consumed in the same period of time. To do this, it is necessary to opt for renewable energies, using fossil fuels with a reduced carbon content as an alternative, and to enhance energy efficiency. This is a strategy that must be shared at a local, national and international level, with changes on several fronts that – while requiring time and commitment – represent the only viable way to safeguard our planet.

What are the advantages for the future

The benefits of decarbonisation are all looking to the future: the more changes we make today to reduce our environmental impact and CO2 emissions , the more clean resources in balance with the needs of the planet we will have tomorrow. The more sustainable choices we make today, the more future generations will be able to appreciate the possibilities offered by our planet. These are innovative energy technologies that really make a difference enabling significant environmental, economic and efficiency benefits that, as seen above, are vital to our near future.

Refrigeration energy: what it is and what are its uses

Cooling energy is usually used in the form of chilled water at a temperature of 7-12°C. Where is it needed? We can start from the classic air conditioning of working environments, warehouses, offices etc. to industrial processes that require the cooling of specific production machinery up to Data Centers and Control Rooms.
By means of lithium bromide absorption chillers, we can produce the necessary cooling energy using the heat from the exhaust fumes coming out of the turbine, in this way we obtain the combined production of 3 different energies: electrical, thermal and cooling: Trigeneration.
Here’s what to know about the advantages and related procedures thanks to the solutions offered by IBT Group in collaboration with partners Century Corporation and Capstone Green Energy.

The absorption refrigeration unit

Trigeneration, also known as CCHP (Combined Cooling, Heating and Power), also allows the production of cooling energy useful for production processes and/or air conditioning of the rooms.
Century absorption refrigerators produce cooling energy using waste heat energy, but not electricity.
The transformation of waste heat energy into cooling energy takes place by means of the absorption cycle, which takes place in the following heat exchangers:

  • The evaporator: under high vacuum conditions, water boils at very low temperatures (about 3°C) and removes heat from the chilled water, thus creating water vapour at low temperature.
  • The absorber: this low-temperature water vapour then flows into the absorber, into which a highly concentrated aqueous solution of lithium bromide is sprayed; once these two elements have combined, the water vapour precipitates as a dilute solution.
  • The generator: the diluted solution is sent to the generator, where it is heated thanks to the recovered thermal energy. At this point, the steam separates from the solution (which becomes very concentrated) due to the high temperatures, and the solution is finally sent to the absorber.
  • The condenser: Water vapour flows into the condenser, which is cooled by water at room temperature. Here, it is transformed into distilled water which is then sent to the evaporator.

What are the advantages

First of all we are in the field of ENERGY EFFICIENCY. The only use of waste heat, instead of electricity, allows a considerable saving of primary energy and consequently the reduction of CO2 emissions.
Other advantages of the production of cooling energy from trigeneration are the high productivity indexes (2,000 cold kW are obtained with less than 10 electrical kW), the simplicity of management and reduced maintenance. Without neglecting the ecological aspect (it is a 100% safe process for the ozone layer, without CFCs), the low noise emissions and vibrations and the possibility of remote control. Finally, it is characterized by modulability, which guarantees high efficiency even in non-project conditions, by the possibility to adjust the temperature in a simple and immediate way and by the patented anti-crystallization system. All this is possible thanks to the solutions of Century Corporation, a South Korean company leader for over 50 years in the production of absorption refrigerators, electric refrigerators and turnkey HVAC systems for civil, industrial, nuclear and marine sectors and of which IBT Group is exclusive partner for Europe: their systems have a life cycle of over 30 years, thanks to their solid structure, which makes them a certainty for any application needs.

Trigeneration using absorption technology

The trigeneration realized with turbine cogenerators to feed absorption chillers allows to feed air conditioning plants and/or industrial processes in different sectors, from food & beverage to chemical, from pharmaceutical to paper industry for example. To power the turbine, liquid or gaseous fuels, fossil or renewable energy sources can be used.
The Capstone turbines, which operate in a patented “oil free” regime, produce electricity and “clean” heat. The part of the heat that is not used for the customer’s processes, is collected and conveyed in order to activate the absorption cycle of the Century chiller: the result of this trigeneration process is to obtain 3 different forms of clean energy, with a single source of primary energy (significant cost savings) while limiting the tons of CO2 released into the atmosphere.

What are biomasses and how are they used in the energy sector?

Biomasses are organic substances, specifically, according to DLgs 387/03, art. 2, paragraph 1, letter a, biomass is defined as “the biodegradable part of residual products from agriculture (including animal and plant substances) and forestry and related industries, as well as the biodegradable part of industrial and municipal waste”.
Biomass energy is actually the first renewable energy used by man! In order to obtain energy from biomass it is necessary that it produces biogas: a natural gas consisting mainly of methane, carbon dioxide and other elements (such as oxygen, hydrogen and nitrogen) and is obtained by means of anaerobic fermentation of organic substances called biomasses (for example, OFMSW or waste from agriculture and agro-industrial activities).
In order to obtain a significant economic benefit, it is necessary to have a rather high material quantity of biomass, therefore very large processing areas.
The reference legislation also recognizes as biomasses the waste of organic substances such as OFMSW and the biodegradable part of industrial and municipal waste.

How a biogas plant works

Biogas is mainly used for the production of electrical and thermal energy, in cogeneration. In the last 5 years there has been a strong implementation of biogas plants:
Capstone Green Energy is a leader in cogeneration systems with gas turbines that use “oil-free” technology, a patent of aeronautical origin that refers to the complete absence of lubricating oil inside the turbines thanks to the use of air bearings capable of supporting the turbine shaft in rotation without mechanical contact.
Thanks to its exclusive technology, it is possible to achieve energy self-production by using as fuel the biogas produced in water treatment plants following the anaerobic digestion of supero sludge and/or of FORSU (Organic Fraction of Municipal Solid Waste), that is the organic material collected through separate waste collection.
This system is characterized by high overall efficiency, low maintenance requirements and near-zero emissions; moreover, it works even in presence of methane-poor biogas (CH4 > 30%) or with non-constant flow rates, thanks to the modulation capacity of the turbine, a factor that makes it particularly suitable for an end-of-life landfill. Finally, IBT Group is able to provide biogas analysis and/or treatment systems so that its qualitative characteristics are suitable to feed a cogeneration plant: in this way, it is possible to exploit in the best way both methane-poor biogas (like the one from landfills) and the one from anaerobic digestion (like the one from water treatment plants).

Where is biomass used?

Thanks to the partnership with Capstone Green Energy, IBT Group is able to provide biogas powered solutions perfect for end-of-life landfills and water treatment plants.
With regard to landfills, Capstone oil-free technology allows turbogenerators to operate even in the presence of biogas with low percentages of methane and decreasing flow rates over time, even in the case of landfills at the end of their life cycle.
In water treatment plants, on the other hand, again by means of oil-free Capstone technology, turbogenerators can operate even in the presence of biogas with low percentages of methane, or not with constant flow rates, ensuring efficiency and avoiding the problems mentioned above. And it is precisely in these areas that enormous progress has been made: thanks to continuous re-search and technological progress, it has been possible to make energy efficiency in compliance with stringent environmental protection regulations, using the waste we produce in our homes, i.e. waste organic material and waste water (white) of our human activities.
Purifiers and landfills use the electrical and thermal energy produced for the operation of the purifiers and biogas production equipment, as well as for their own offices: in perfect cycle!

Energy efficiency: what it is and how to achieve it

IBT Group, thanks to the collaboration with technological partners such as Capstone Green Energy and Century Corporation, deals with energy efficiency solutions made and sized according to the specific needs of each customer and using the latest technologies, so as to help companies to be more competitive in the market, always in total respect of the planet.
Such tailor-made solutions can reduce primary energy consumption and lower energy bills. Here is what to know when talking about energy efficiency!

What does efficiency mean?

When we talk about energy efficiency, we refer to all those interventions useful to obtain an increase in energy efficiency. In short, the aim is to increase the efficiency of the process so as to obtain the same result with less consumption and therefore fewer emissions into the atmosphere.
This principle is applicable to both public and private buildings, as well as to companies and commercial structures belonging to the most varied sectors. The energy efficiency allows to use the energy sources in an optimal way, with a lower energy consumption but without this going to affect minimally the performance. In addition, this expenditure aimed at improving energy efficiency also has numerous tax advantages. In full compliance with the objectives of the European Union, through the Green Deal (European Green Pact), aims to achieve climate neutrality by 2050: in this document, you can read the declaration of intent that aims to “improve energy efficiency, reduce dependence on energy imports, reduce emissions and stimulate employment and growth.

What is meant by energy efficiency interventions?

The objective of energy efficiency interventions is to optimise the relationship between energy requirements and the level of emissions. Possible works include the covering of walls or window frames with insulating material, the replacement of air conditioning systems and/or old generation boilers, the installation of solar panels, the introduction of lighting sources such as LEDs and the adoption of systems designed to produce energy with significant energy savings and emissions not released into the atmosphere, namely those applied to cogeneration and trigeneration: the first involves the simultaneous production of electrical and thermal energy, the latter in the form of hot water, steam, hot air and diathermic oil. The second involves a further phase of production of chilled water. Both solutions are offered by IBT Group through its partners Capstone Green Energy and Century Corporation, both leaders in the field of energy efficiency. Thanks to the work of energy efficiency, you can reduce the amount of energy demand and increase the performance of efficiency, while respecting the environment.

How do you measure energy efficiency?

When we talk about energy efficiency, it is very important to evaluate how and where energy is used, in what quantity it is consumed, what economic savings it brings and what impact it has on environmental resources. That’s why it is essential to install, both at private and public level, devices and tools that allow to monitor the real consumption and to obtain an effective optimization especially in the long term. To allow this, IBT Group provides a SCADA system with the visualization of all data, parameters and status of the plant also remotely. In addition, in a dedicated section are indicated all the economic values of savings generated by the system.

White certificates for cogeneration

When we talk about “cogeneration”, a process that allows the simultaneous production of electrical and thermal energy from a single primary source, obtaining economic savings thanks to lower fuel consumption, we cannot ignore the important facilitation represented by incentives such as white certificates. But what are they exactly? What advantages do they represent and, above all, how can they be obtained?

How do the White Certificates work for cogeneration?

The white certificates (also known as Energy Efficiency Certificates-TEE) are subsidies introduced by Ministerial Decree of 24 April 2001, and have the purpose of encouraging the implementation of energy efficiency projects such as the adoption of cogeneration plants. As made known by the European Directive 2004/CE, these are defined as high efficiency (or CAR) when the value of primary energy saving (PES) is at least 10% or, in the case of micro-cogeneration units (< 50 kWe) or small cogeneration units (< 1 MWe), when it assumes any positive value. White certificates are awarded annually by the GSE, which first ensures that the efficiency has been achieved and then awards the relevant number of white certificates for the following 10 years: it also carries out a preliminary examination of units not yet in service and indicates any shortcomings or changes to be made if a project does not comply with the regulations.

The criteria for taking advantage of the benefits of high-efficiency cogeneration

As mentioned in the previous paragraph, a cogeneration plant can be defined as CAR if its efficiency exceeds a certain threshold which varies according to the power class of the cogeneration unit. The cogeneration units that can take advantage of these benefits are:

  • Those brought into operation as a result of new construction or renovation after March 6, 2007, for a period of 10 calendar years, beginning on January 1 of the year following the year of entry into operation.
  • Those brought into use as a result of new construction or renovation after 6 March 2007 and combined with a district heating network, for a period of 15 calendar years starting from 1 January of the year following their bringing into use.

How to obtain incentives with high-efficiency cogeneration

Every year the GSE verifies the CAR requirements and the allocation of TEE: to send your request for access to incentives, you must use only the RICOGE Portal, which allows you to upload all the data and documents needed to start the practice. It is also available a RICOGE User Manual to better understand all the steps of compilation and submission of documentation, which must be submitted every year by March 31 of the year following the production to which it refers. The preliminary documentation instead can be presented throughout the year. IBT, if the customer re-quests it, can be available for the preparation and presentation of the relative GSE practices for its own supplied plants.
The main benefits that current legislation recognizes to CAR are numerous, among which we find:

  • the precedence, in dispatching, of electricity produced from cogeneration over electricity produced from conventional sources;
  • tax relief on excise duty on methane gas used for cogeneration;
  • the possibility of accessing the on-site exchange service for electricity produced by High Yield Cogeneration plants with nominal power up to 200 kW;
  • the possibility of applying simplified technical and economic conditions for connection to the electricity grid;
  • the possibility of obtaining tariff concessions for plants powered by Renewable Energy Sources.
