National energy balance
According to the information provided by rynekelektryczny.pl, in November 2021 the total capacity of all energy sources available in Poland increased to 54.8 GW. Just a few months earlier, around January and February 2021, Poland was excited about crossing the magical limit of 50 GW. In theory, the increase is quite large, which can mean a possibility of introducing certain investments in the energy market. Renewable energy sources, with a total installed capacity in November 2021 as much as 16.3 GW look interesting in this list. This means there has been an increase of around 36%, with solar installations making the biggest impact here.
Energy as a key to innovation
Why is it worth mentioning at all? One of the main reasons is beacaue in the coming years - if there is no unexpected revolution on the Polish energy market - we will face a real energy catastrophe. The largest Polish coal-fired power plant is located in Bełchatów, which can generate as much as 5 GW of energy, but it doesn’t really matter, since it has to be phased out after 2030. The same applies to the second largest power plant in Kozienice. Let’s also keep in mind that the majority of power plants that today determine the country’s energy power, were built in the 1970s and 1980s. It means that they require investments, and taking into account what is going on with the coal energy, they will be gradually decommissioned as well.
Ecomarketing in practice
A typical, portable EVSE car charger isn’t a very practical device. It provides “only” 2.3 kW of power, which means that electric cars equipped with it can charge up to 20 hours. If there are a million of such cars, the simultaneous load on the national power grid increases to 2.3 GW, which - considering the above statistics, but also innovations in industry, construction, etc. - is a lethal value for the Polish power grid. The same issue is visible in other innovative solutions, such as inductive charging of electric cars. The wireless charging of the vehicles is still at the stage of development and - unfortunately - still characterized by a relatively low efficiency.
By the way, WITricity is working on new induction chargers for electric cars. Their power is planned to be as much as 11 kW, and the efficiency is 93 percent. Can the Polish energy sector take in such innovations?
