Paying when energy prices are negative? Here's how the Embion EMS helps.

Negative energy prices are increasingly becoming a reality in the energy market. This happens when there is a surplus of electricity, for example due to high production of solar and wind energy at times when demand is low. In such cases, energy prices can even fall below zero. For users with dynamic energy contracts, this means that feed-in to the grid not only generates nothing, but actually costs money.

Costs due to feed-in

One of our customers noticed that their energy costs suddenly went up even though they were delivering a lot of energy back to the grid. This was due to negative energy prices: moments when feed-in does not generate revenue, but actually costs money. With the Embion EMS, we solved this problem by using energy smarter and avoiding costs.

Smart energy management with the Embion EMS

With the Embion EMS, a solution was developed that responds to the dynamics of the energy market. The system works fully automatically and continuously monitors EPEX prices. As soon as prices become negative, the EMS responds accordingly. The energy generated is first used locally as efficiently as possible. Is there still a surplus? Then production is reduced by reducing inverters. This prevents energy from being delivered to the grid at negative prices.

If negative prices persist longer, the system may even choose to take energy from the grid. The Embion EMS then temporarily shuts down production, allowing the cheaper energy from the grid to actually provide a financial benefit. Instead of losing money, an opportunity arises to make a profit by making smart use of market prices.

The energy market is changing, and smart technologies such as the Embion EMS make it possible not only to keep up with that change, but to take advantage of it.
