Energy origin guarantees – how do they support the development of green energy?
Energy origin guarantees are an element of the European Union's policy – and by extension, also that of the member states – aimed at supporting the development of the renewable energy market. On one hand, they serve an image-building purpose. On the other, they are tradable and should be considered a real profit for companies. What exactly is an energy origin guarantee, how to obtain it, and how can it be used?
What are negative energy prices and why do they occur?
Negative electricity prices are a phenomenon that at first glance may seem paradoxical – why would producers pay consumers to use energy? In reality, this is the result of dynamic changes in the energy market, driven by the rise of renewable energy production and the volatility of demand. In this article, we explain what negative energy prices are, why they occur, and the challenges and opportunities they present for energy systems.
What is Reactive Power Compensation? Explained!
In today’s economic reality, every kilowatt-hour counts — both for businesses and households. Reactive power, although not immediately visible, can present a significant challenge to the efficiency of power systems. How can reactive power compensation help? Why is it worth addressing? And what benefits can it bring to energy management?
Offshore wind farm - how do they work? Poland and world
The energy transition of individual countries - including Poland - involves the search for renewable energy sources. In addition to the well-known photovoltaics using solar energy or wind farms exploiting wind power, offshore wind turbines are playing an increasingly important role in this area. How do these devices work and what does their future look like?
Prosumer – who is it and what is their role in the world of renewable energy?
The operation of modern power systems, known as smart grids, no longer relies solely on electricity generation by a few large, state-owned providers. Prosumers are playing an increasingly important role in these systems. Who is a prosumer, and why is their role in the world of renewable energy so crucial?
What is a OSD network is? We explain!
Although the electricity grid is gradually being rebuilt from a centralized model to a smart grid emphasizing a plurality of smaller and larger energy producers and distributors, there still has to be someone in charge of balancing energy nationwide and maintaining the central grid that we all use - prosumers, consumers and businesses alike. That role is played by the DSO distribution network. What is it and how does it work?
What is the CSRD Directive?
In recent years, ESG has become one of the top five global business trends. In the European Union, the ability to conduct business while adhering to sustainable development principles is gaining rapid importance. For some, it’s an additional obligation and immense stress; for others, it presents opportunities linked to economic stimulation. Nevertheless, all entities will eventually have to take action in this area and, more importantly, report the steps they have taken. The CSRD Directive will facilitate this process, providing a standardized requirement for reporting on implemented and ongoing ESG activities. Learn more about it below!
Day-ahead Market. What is it?
The Day-ahead Market gained media attention with the introduction of the new photovoltaic billing system. This refers to net-billing, where the price per kilowatt-hour is not fixed but is determined in relation to specific indicators. However, the Day-ahead Market is a broader concept that is inextricably linked to Power Exchanges. What should be known about this market? Who trades on it, what is traded, and under what rules?
What is the Spot Market? Energy Without Secrets
Electricity trading through immediate (spot) transactions is carried out via short-term transactions. These can be executed within the operations of the day-ahead market, as well as the spot market. Let’s take a closer look at the spot market. How does it work, and what does it entail?
Carbon Border Adjustment Mechanism (CBAM) – What is it and what are its goals?
The Carbon Border Adjustment Mechanism, or CBAM for short, is a price adjustment mechanism at the borders that takes into account CO2 emissions. It applies to the prices of raw materials, semi-finished products, and products whose production has the strongest impact on increasing greenhouse gas emissions into the atmosphere.

Energy Intensity – What Is It and How Does It Affect Energy Consumption?
Using road, residential, or service infrastructure requires specific energy inputs. The less energy that needs to be consumed to use the infrastructure, the more energy-efficient the facility is. The concept opposite to efficiency is energy intensity. How should we understand it, and what can we do to reduce energy intensity in various industrial sectors?
The Energy Supply Chain – How Does It Work?
The energy supply chain is an extensive and fairly complex process. It begins with the extraction and processing of raw materials. Then, energy is generated, distributed, and delivered to end users. The process of energy transformation, along with the continuously growing demand for power, requires a solid understanding of supply chain mechanisms.
