Is the ESCO model cost-effective?

The ESCO model is not a universal solution for every energy-efficiency investment. Under the right conditions, however, it can significantly accelerate a company’s energy modernization while reducing both technological and financial risk. The greatest value of ESCO is not financing itself, but the combination of financing with a guaranteed energy performance outcome. This is precisely what distinguishes ESCO from leasing or investment loans. For industrial companies, a detailed, project-specific analysis is crucial, covering both technical parameters and the financing structure. Only this approach allows a reliable assessment of whether the ESCO model is truly cost-effective in a given case.

What industrial companies need to know about ESG reporting

ESG reporting is the systematic process of disclosing information about a company's impact on the environment, society, and the way it is governed. An ESG report expands traditional financial reporting by including non-financial information that enables stakeholders to assess how well a company is prepared to operate in the context of the climate transition while meeting regulatory requirements and stakeholder expectations. For industrial companies, ESG reporting has become an integral part of strategic management. This is particularly true for energy-intensive businesses, where CO₂ emissions, energy consumption, process efficiency, and occupational health and safety have a direct impact on both operating costs and the company's long-term growth potential.

What is toe – tonne of oil equivalent?

In the field of energy efficiency and the white certificate scheme, the term toe (or TOE) appears frequently. For industrial companies implementing investments aimed at reducing energy consumption, it is one of the key units used to assess the results of energy efficiency projects. Energy savings that form the basis for obtaining Energy Efficiency Certificates, commonly referred to as white certificates, are expressed in toe. Although the term has been used in technical documentation, energy efficiency audits and legal regulations for many years, many people still do not fully understand what toe actually is, why this particular unit is used, or what its real economic value is within the white certificate scheme.

Capacity charge: who will pay the most and how can costs be reduced?

The capacity market charge is a component of the electricity bill that has been in force in Poland since 2021. It was introduced alongside the launch of the capacity market - a mechanism designed to ensure the security of electricity supply by compensating generation units for maintaining readiness to produce electricity. As a result, electricity consumers finance not only the generation and transmission of electricity itself, but also the maintenance of adequate reserve capacity within the national power system. Funds collected through the capacity market charge are allocated to entities that commit to delivering capacity during periods of peak electricity demand. This enables the transmission system operator to reduce the risk of power shortages and system failures.

What is a gas turbine?

A gas turbine is a flow machine used to convert the chemical energy of fuel into mechanical energy and, most commonly, into electrical energy. It belongs to the group of heat engines operating on the Brayton cycle, in which air is compressed, heated through fuel combustion, and then expanded in a turbine. Due to their high efficiency, exceptional reliability, and compatibility with heat recovery systems, gas turbines have been widely used for many years in power generation and across numerous industrial sectors, particularly where there is a simultaneous demand for electricity and process heat. In industrial applications, a gas turbine is often the central component of cogeneration and trigeneration systems.

How to leverage cogeneration for additional benefits – price arbitrage and flexibility

Cogeneration is the simultaneous production of electricity and useful heat from a single fuel source, most commonly natural gas. Its primary value lies in the system’s high overall efficiency, reaching 80–90%, which significantly reduces energy losses compared to the separate generation of electricity and heat. In industrial applications, however, cogeneration is no longer merely a generation technology. It is becoming part of an energy management system that can serve as a cost stabilizer, a market arbitrage tool, and a source of additional revenue streams.

Efficiency of compressed air systems

Compressed air systems are among the most energy-intensive auxiliary systems in industrial facilities. In many enterprises, they account for a dozen or even several dozen percent of total electricity consumption. Despite this, for years they have been treated as background infrastructure supporting production processes, without regular efficiency analysis. Meanwhile, improving the efficiency of compressed air systems is one of the fastest and most predictable ways to reduce energy consumption and operating costs.

How to prepare for the implementation of cogeneration?

Cogeneration (CHP – Combined Heat and Power) is one of the more compelling technologies for improving energy efficiency in industrial facilities. The simultaneous production of electricity and heat makes it possible to significantly reduce primary energy losses, lower operating costs, and decrease CO₂ emissions. However, the technology itself does not guarantee success – proper preparation, a reliable analysis of the energy consumption profile, and a well-informed selection of capacity and operating mode are crucial. Cogeneration can substantially improve a plant’s energy efficiency and reduce costs, including capacity charges, provided it is treated as part of a broader energy management strategy rather than as a standalone technological investment.

ESCO model in practice

As the steadily growing number of projects delivered under the ESCO model shows, more and more companies are looking for ways to implement energy upgrades without burdening their investment budgets. One of the most interesting solutions of this kind is the ESCO model (Energy Saving Company) - a form of cooperation in which an external partner designs, finances, implements, and maintains an energy-efficient investment, while the Client repays it from the savings generated. This enables companies to carry out an energy transition without committing their own capital (CAPEX) and while transferring the risk of not achieving the expected results to the ESCO company.

Organic Rankine Cycle (ORC)

The Organic Rankine Cycle is a heat recovery method that allows for the efficient use of waste heat and low-temperature energy sources to generate electricity. ORC installations enhance energy efficiency, reduce energy costs, and contribute to the reduction of CO₂ emissions. The Rankine Cycle is a classic thermodynamic process used in steam power plants, in which water is heated to steam and then drives a turbine. In the Organic Rankine Cycle, however, organic fluids with a lower boiling point are used instead of water. This makes it possible to utilize heat sources with much lower temperatures - even in the range of 80–350°C - which would be insufficient for conventional steam power plants.

Where to obtain financing to implement the projects indicated in the company energy audit?

Energy audits of enterprises are a legal requirement for large companies, and soon also for SMEs. Above all, however, an audit is a tool that identifies the potential for improving energy efficiency. It should include specific technical and organizational actions that can reduce energy consumption, cut emissions, and deliver tangible economic benefits. Yet the process does not end there – equally important is the implementation of the recommended solutions, which can be costly and complex. Even if a company has a sufficient own budget for energy-saving investments, additional financing is always welcome.

How to effectively manage reactive power?

Reactive power is a form of electrical energy that does not perform useful work but is essential for the operation of industrial equipment and for maintaining the electromagnetic field in alternating current (AC) circuits. This type of energy is not consumed in the traditional sense – it does not convert into heat, light, or motion – but rather “circulates” between the grid and devices, placing an additional load on the power infrastructure. Although often underestimated, reactive power significantly affects operational costs, system efficiency, and the reliability of the power network. Proper reactive power management not only helps avoid additional charges but also enhances the overall efficiency of the electrical infrastructure.
