Power generation in the classical model means:
The price of 1 kWh includes the costs of mining, generating and transmitting electrical energy.
When paying for the actually supplied energy, each of us covers also costs of low efficiency of the conventional energy generation (circa 60% of energy loss in the generation and transmission process) and extremely high costs incurred for reducing the negative impact of this energy sector on the natural environment.
You pay too much and, additionally, you are 100% dependent on the system in which electricity prices increase and you cannot rely on supply stability.
By building your own energy source, you build your energy independence, protect the natural environment, and – in the first place – you SAVE MONEY!

OWN micro CHP STATION
Assumptions (a sports and recreation facility with a swimming pool):
Reduction in the facility running costs: amount of aggregate savings in a 20 years’ installation operation cycle (PLN) | 7 066 310 |
Level of the energy independence achieved | 94% |
The ratio of aggregate savings from 20 years to the current annual costs of utilities | 591% |
Installation price on contract termination (PLN) | 1 |
Aggregate savings due to the operation of the micro CHP installation over 20 years cover the current annual costs of electrical energy purchase and heat production nearly 6 times
