Energy Storage – Key Legal Changes for Entrepreneurs After the Amendment to the Energy Law
Energy storage has been one of the most dynamically developing segments of the renewable energy market for several years. Until recently, it was primarily seen as a technological solution to increase self-consumption of energy from photovoltaic installations. However, it is now becoming a full-fledged element of the national electricity system, enabling effective energy management and increasing supply security.
The importance of energy storage has also been recognized by the legislator. On April 30, 2026, a comprehensive amendment to the Energy Law, referred to as the so-called “network law,” came into force, introducing a number of changes significant for investors, entrepreneurs, and operators of electricity systems. The new regulations primarily aim to streamline the process of connecting new installations to the grid, increase the availability of connection capacities, and create better conditions for the development of energy storage.
What is cable pooling?
Cable pooling involves sharing a single electricity connection by several generating installations. This solution has been functioning in the Polish legal system since 2023 and initially allowed the use of a single connection only by renewable energy installations, primarily photovoltaic farms and wind power plants.
The idea behind this solution is relatively simple. Different technologies produce energy at different times of the day and year. A photovoltaic power plant achieves its highest production during the day, while a wind power plant often operates most efficiently at night or in winter. This allows for much more efficient use of the same connection infrastructure without the need to build additional connections.
Why is energy storage gaining importance?
The increasing number of renewable energy installations is causing greater strain on the national electricity grid. Energy production from photovoltaic farms or wind power plants is dependent on weather conditions, which translates into variability in energy supply.
Energy storage allows for the accumulation of excess produced energy and its use during periods of increased demand or limited production. From the entrepreneurs’ perspective, this means the possibility of increasing self-consumption of energy, reducing the costs of purchasing energy from the grid, and greater stability in business operations.
At the same time, energy storage is becoming an important element of new renewable energy projects – both as standalone investments and installations cooperating with photovoltaic farms or wind power plants.
Amendment to the Energy Law – what has changed since April 30, 2026?
The amendment to the Energy Law focuses primarily on restructuring the process of connecting new installations to the grid. The legislator’s goal was to unlock connection capacities occupied by projects that had remained at the planning stage for many years.

One of the key changes in the indicated project is the expansion of the possibility of sharing a single connection point. Currently, not only different renewable energy installations can use a single connection, but also energy storage, which allows for more efficient use of the existing network infrastructure.
For investors, this means the possibility of reducing the costs of building new connections and greater flexibility in designing investments. This solution can significantly increase the profitability of new projects, especially in regions with limited availability of connection capacities.
Energy Storage Before Obtaining a License
A favorable change for entrepreneurs is also the ability to conduct activities related to energy storage even before obtaining a license, provided that the requirements specified in the law are met.
This change allows for more efficient launching of new investments and reduces the risk associated with waiting for the completion of administrative proceedings. For investors, this means greater predictability of the schedules of implemented projects.
What Do the New Regulations Mean for Entrepreneurs?
Entrepreneurs should primarily pay attention to the need for more thorough preparation of projects before submitting an application for connection conditions. Shorter deadlines and new financial obligations mean that submitting applications “in advance” is no longer profitable.
On the other hand, the new regulations increase the chances of obtaining connection conditions for investors who are genuinely prepared to implement the project. In the long run, this may translate into faster development of energy storage and improved availability of network infrastructure.
Summary
The amendment to the Energy Law opens up new opportunities for entrepreneurs in the implementation of investments in energy storage, while imposing on investors the obligation to adequately prepare the connection process and adapt projects to the new regulations. In practice, a proper analysis of the regulations at the planning stage of the investment allows avoiding many legal and organizational risks.
