Energy storage projects

Energy storage: the gold mine at Ampic

The increasing penetration of renewables has dramatically increased the volatility of electricity prices on the stock market. It is often the case that during sunny or windy spells, overgeneration causes prices to briefly approach zero, and occasionally even slip into negative territory. At such times, a battery storage system can charge very cheaply. This cheap energy can then be sold at a higher price later in the evening or when there is no wind, when supply is tight and prices have risen. This is the arbitrage option.

Energy storage systems can be veritable money-making machines through power market arbitrage.

The arbitrage is based on the difference between the minimum and maximum prices within the day. In recent years, there has been a tendency for daily minima to shift from dawn and night hours towards midday hours, due to the very rapid spread of solar PV systems (the basis for 1 cycle per day battery operation). However, a small price fluctuation has also been observed between dawn and early morning hours (possibility of 2 cycles per day operation). Let's see how much profit a 10.75 MWh industrial battery (at 75% utilisation) can generate based on HUPX market prices:

Other options
System frequency control: 10 MWh of capacity already provides an opportunity to register in the frequency regulation market, which could provide ongoing additional revenue.
"Peak shaving": in specific cases, as little as 5-10% of battery system capacity is sufficient to reduce peak loads. This means that the extra power consumption that rarely occurs does not appear as an extra performance cost.
Improving energy security: The battery capacity can even be used as a backup to increase availability.
AI-supported visualisation aid: using AI technologies, we use visualisation tools to calculate and scale energy storage systems, helping customers to make the best decision.
General construction: a full construction service, where we work with the latest semi-solid-state batteries with 95% capacity utilisation, up to the 10 MW container we have developed for you.
For "green" projects, a unique financing offer: expert help in finding financing options, even without a co-payment and with a significant immediate return on investment for sufficiently high time-series consumption.
