You give the impression that heavy consumers do not pay because they only pay a few cents per kWh, which is incorrect. A large consumer pays mainly on power, but not so much on consumption. That purchase right of 32MW as well as the purchase obligation is what a large consumer pays for.
Until now, it was only the small consumer (mainly consumer) who was billed purely on consumption, something that is no longer tenable.
After all, the challenge has always been to keep the net in balance, how much should I produce vs how much decrease there is. If a large consumer indicates that it needs 32MW, but suddenly it does not decrease, then you have 32MW on your network that you cannot get rid of. But also vice versa, if it suddenly decides to purchase 64MW, you suddenly have a 32MW shortage. The large consumer is therefore heavily financially punished for this, if it suddenly starts to demand more or less power.
What you see in production companies is that due to a sudden standstill (power down) or when production has to start up (power up), you have to impose an enormous amount on the energy bill. That battery they put here is presumably purely for this, to keep them from causing spikes in both directions.
In the past, that consumption by consumers was predictable, small and it was not technically feasible to start billing on power. However, technology does not stand still and with the rise of EV, solar panels and heat pumps, that predictability disappears. This means that if the prices remain stable, you will pay much less for consumption, but you will charge if the required power fluctuates strongly. The consumer will therefore come closer to how things work with large consumers.
Holiday homes will then pay more below the line, they consume very little but they ask for 10 months 0 and then suddenly ask for 2 months. That is also logical because the fixed costs for the network are equal to a non-vacation house while you can only sell production capacity for 2 months that you cannot lose for the other 10 months. The same story goes for solar panels that are directly connected to the grid, once billed correctly many current owners will be angry because their variable demand for power will push their bill up.
However, if we stick to the old system, where consumers demand more power and more variable, those costs are there anyway. In the old system, those costs are simply spread over everyone, but do we want that? I certainly don’t, because then you don’t have the financial impulse to improve it and, like this company, to invest in a battery, for example.
