HH2E answers your initial questions.

System operators with a system of more than 100 kWp (connected load) must market the electricity directly in accordance with the applicable EEG. To do this, they sell the electricity to a marketer, who in turn sells this electricity on the electricity exchange. Direct participation in the electricity exchange is only economically viable for very large electricity production volumes.

The marketer receives the market value on the electricity exchange. The system operator receives the market value from the marketer and the market premium from the grid operator. Both together result in the value to be invested. The value to be applied corresponds to the EEG feed-in tariff plus 0.4 ct/kWh.

As a rule, marketers charge a considerable service fee, which means that the system operator receives less than the comparable feed-in tariff. This significantly impairs profitability. In addition, the electricity purchased by the marketer is only sold on the exchange.
HH2E wants to take your electricity and put it to a higher value use: We want to use the green electricity to produce hydrogen. That is why we do not charge a marketing fee for attractive systems: In short: you receive the full value of the electricity.

Renewable energy systems must be remotely controllable. This ensures that the marketer can shut down the system if, for example, negative prices occur on the electricity exchange.
Remote control is carried out by a small technical device on the generation plant, which is installed during the construction of the plant or retrofitted.

HH2E accesses the existing remote control technology so that no additional technology needs to be installed if HH2E markets the electricity. However, HH2E must provide evidence of the remote control to the grid operator when switching to HH2E, so that we can provide proof of installation. The installation certificate and a remote control certificate are required. HH2E submits these documents to the network operator together with the remote control certificate issued by HH2E.

Concerning remote control: HH2E is interested in the electricity, so compared to normal direct marketers, HH2E will shut down your system much less frequently. We say: Use it instead of lose it, rather use the electricity than leave the generation unit unused.

Renewable electricity is often produced in the north of Germany and transported via the grids to the main areas of consumption in the south and west. In many cases, the transmission capacity in the grids is not sufficient to transport the electricity. In this case, the grid operators regulate the plants down and conventional power plants are ramped up to cover demand in the south of Germany. This is called redispatch. This results in considerable costs because, on the one hand, the curtailed power plants are remunerated and, on the other, the additional power plants that are started up are also remunerated.
HH2E builds and operates plants for the production of hydrogen in regions where electricity generation has to be throttled particularly frequently. Through the additional, flexible demand for electricity at HH2E’s production sites, which otherwise tend to have low consumption, HH2E is making an important contribution to reducing the amount of otherwise curtailed electricity and at the same time transporting CO2-free energy in the form of hydrogen via the pipeline to industrial consumers.

Surplus feed-in means that part of the electricity generated is consumed directly on site and only the rest, the surplus, is fed into the grid.This form is often used by commercial and industrial customers who have the PV system on the roof of the production hall and are primarily self-sufficient. However, at sunny times and at weekends, the electricity is not needed and is fed into the grid. This is where HH2E comes into play: HH2E is happy to take this electricity because we primarily produce hydrogen whenever electricity from renewable plants is available.
HH2E remunerates you for every kWh fed in at the current market price on the exchange. In addition, HH2E pays out the market premium received from the grid operator so that you only receive the payments conveniently from HH2E. This also reduces the administrative effort for you.
