Poland’s energy holding company TAURON has commissioned a photovoltaic power plant combined with an electricity storage system in Zakopane. The company wants to draw the attention of prosumers and small entrepreneurs to the importance of producing energy at home and using it “on the spot”.
“The idea is that the electricity produced from the sun does not go directly to the grid,” said Artur Warzocha, vice-president of Tauron for corporate affairs. “In the near future, every prosumer who wants to optimise the production and consumption process will face the need to install such a device. That is why we are carefully observing changes in the law enabling the launch of the program of subsidies for the purchase of energy storage.”
The photovoltaic installation consists of 120 monocrystalline panels which in total give a power of almost 45 kilowatt-peaks (kWp) and the annual electricity production will amount to approximately 36 megawatt-hours (MWh). The produced energy will go to a storage system with a capacity of 40 kilowatt-hours (kWh). If there is a need to store more energy, the battery capacity can be increased to 140 kWh.
“Statistically, the highest electricity consumption is in the morning and in the evening, meaning when the panels work with minimum power or not at all,” explained Piotr Apollo, CEO of TAURON Nowe Technologie. “During the day, its efficiency increases significantly, but then the demand for electricity decreases. The use of an energy storage facility allows consumers to balance the energy process.”
The investment falls under the company’s goal to have 1,600 megawatts (MW) of renewable installed capacity by 2025 and it is in line with the country’s targets as well.
“Renewable energy sources mean energy independence and clean air for us and future generations,” commented Ireneusz Zyska, Deputy Minister of Climate and Environment. “Thanks to investments such as the one launched by Tauron, this path will be shorter and shorter. Also, these investments will provide an impulse for the development of the entire economy.”
Indeed, data show that the pace of renewable energy development in Poland is very high. At the end of January 2022, the installed RES capacity reached over 17.4 GW, including 8.1 GW from PV installations.
Mr Zyska added that the development of renewable energy sources should be carried out in a sustainable manner, ensuring the safety of the power grid operation and, in this regard, energy storage technologies will be of key importance.
